Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of be used for Hypertension, enter the orthosympathetic ablation catheter of blocking-up kidney system in the renal artery by the mode that gets involved.
Background technology
Hypertension is common clinical, frequently-occurring disease, calculates according to up-to-date data, and Chinese hyperpietic group surpasses 200,000,000, and is number of the infected and increases year by year, and age of onset is trend in advance gradually.The important organ complication such as the heart that hypertension causes, brain, kidney have very high fatality rate and disability rate, and human health in serious harm.Approximately there are 3000~4,000 ten thousand obstinate hypertension in China, and the following increase that is accompanied by aged tendency of population and obesity, diabetes patient, patient's quantity of intractable hypertension will further increase, and brings great burden for society, family, individual.Without good intractable hypertension Therapeutic Method, open up new non-drug therapy means at present, thereby the deficiency that remedies current pharmacotherapy is simple, it is very urgent safely, effectively to control blood pressure.
Studies confirm that in a large number, the sympathetic nervous system of excessive activation and hypertensive formation are closely related with progress, wherein, the kidney sympathetic nervous system is kidney Sympathetic Nerve and the nervus centripetalis of the most close renal artery wall particularly, the key factor that is considered to the hypertension initiating and keeps.For this mechanism, the foreign scholar has proposed by this new hypertension therapeutic strategy of catheter ablation renal artery sympathetic nerve treatment intractable hypertension.
2009, the people such as Krum at first produce the Symplicity ablation catheter with Ardian company 45 routine obstinate hypertension enforcement kidneys are gone the sympathetic nerve radio-frequency ablation procedure in catheter ablation kidney sympathetic nerve treatment intractable hypertension research (Symplicity HTN-1), confirm simple, the safety of this new technique, antihypertensive effect occurs early, and can keep for a long time.In reaching the tracing study in 2 years, find that the blood pressure that descends increases again, and the kidney merit keeps stable.Nearly ten remainders of clinical research that the percutaneous catheter kidney goes sympathetic nerve treatment are being carried out or are being finished at external a plurality of center, finished or ongoing clinical test results encouraging, this technology is expected to become the revolutionary breakthrough in hypertension therapeutic field.
US 2011/0264075 A1 discloses and has a kind ofly removed orthosympathetic radio frequency ablation catheter for kidney, although this kind conduit that Ardian company produces has certain application in clinical abroad, also has significantly deficiency.At first this kind conduit only can carry out single-point and melts, and generally is to melt around carrying out 6-8 the spiral type of putting in one week of renal artery because kidney removes orthosympathetic radiofrequency ablation therapy, so this kind conduit of Ardian company need to melt 6-8 time, and operating time is long.Ablation catheter for Ardian company can not carry out the problem that multiple spot melts, US 2012/0116392 A1, US 2012/0029510 A1, CN 201110117776.8, thereby CN201110327772.2 arrives the purpose that multiple spot melts simultaneously by radio-frequency ablation electrode is set respectively on many strip electrodes bar, CN 102198015A then realizes that by according to the precalculated position a plurality of radio-frequency electrodes are installed on a spiral electrode stem multiple spot melts simultaneously, although above-mentioned design has realized that to a certain extent multiple spot melts simultaneously in the renal artery, but because radio-frequency ablation electrode and blood vessel wall applying are tight not, so that radio-frequency ablation electrode is easily mobile when melting, and cause ablation range excessive, cause unnecessary damage to the patient; For so that a plurality of radio-frequency ablation electrode attaches simultaneously closely blood vessel wall, US 2012/0101413A1 has adopted the scheme that dilating sacculus is set in revolving the electrode stem of shape, can be so that radio-frequency ablation electrode and blood vessel wall closely attach by in sacculus, being filled with liquid, but the kidney blood flow can be blocked during balloon expandable, easily cause renal ischaemia if the time of melting is grown, and cause unnecessary complication; Be blocked US 2012/0029512 A1 for fear of the kidney blood flow sacculus has been replaced to the tinsel tennis, although solved the problem that the kidney blood flow is blocked, the sacculus that is far from the operation is convenient; It is larger that this stranger's renal artery is walked row variation, and the design of above-mentioned these a plurality of radio-frequency ablation electrodes is difficult to use when the renal artery traveling is morphed, and therefore limited the crowd that kidney goes sympathetic nerve to treat; And the design of above-mentioned a plurality of radio-frequency ablation electrodes is owing to only for radio-frequency (RF) ablation, therefore being difficult to same design is promoted for laser ablation, microwave ablation etc.Secondly the guiding of the conduit of electrode catheter and the above-mentioned a plurality of radio-frequency ablation electrodes auxiliary ablation site that can arrive appointment that all needs to add conduit and conduit is not accurate enough frequently for the injection of Ardian company, therefore can not finely satisfy clinical requirement.Again, the conduit of the injection of Ardian company frequency electrode catheter and above-mentioned a plurality of radio-frequency ablation electrodes all is difficult to the effect that melts is carried out Real-Time Monitoring, therefore is difficult to carry out examination of curative effect in art, so that patient's second operation risk increases.

The Main Function that controllable bending tune 5 is set is to help the section of melting 6 to arrive more easily the ablation locations of appointment, such as so that the easier bending by blood vessel of the section of melting 6 so that the section of melting 6 is easier of assigned direction deflection etc.Cylindrical or the class cylinder design of controllable bending tune 5 preferred employings, different according to the length of different design controllable bending tunes 5.Figure 25 has shown the situation under duty when controllable bending tune 5 is C shape curved design, Figure 26 has shown the situation under duty when controllable bending tune 5 is S shape curved design, this two width of cloth figure all is that the absolute construction 8 of the section of melting 6 describes when being two, when being other design forms for the section of melting 6, only needing to replace the section of melting 6 and get final product.As shown in figure 25, be shaped as C shape after 5 deformation of controllable bending tune, the controllable bending tune 5 of solid line part has represented the situation of a kind of C shape bending, under this shape, controllable bending tune 5 preferred lengths are 60--120mm, controllable bending tune 5 will have two local c1 to contact with the blood vessel medial wall with c2, wherein c1 contacts with the medial wall of renal artery a, and c2 contacts with the medial wall of ventral aorta b, be conducive to like this when melting stablely to melt 9, controllable bending tune 5 this moment preferably and one of them absolute construction 8 at grade, like this for 9 situation as detecting electrode that melt are only arranged on the absolute construction 8, can detecting electrode 19 be set at c1, melt like this 9 or absolute construction 8 on detecting electrode 19 will form a granting electric pulse with detecting electrode 19 on the controllable bending tune 5, one receives electric pulse, certainly for adapting to the renal artery of different tube diameters, a plurality of ring-types can be set near c1 receive detecting electrode 19; As shown in figure 25, the controllable bending tune 5 of dotted portion has represented the situation of another kind of C shape bending, in this case, controllable bending tune 5 preferred lengths are 40--100mm, controllable bending tune 5 can not contact with the medial wall of tremulous pulse, perhaps only there is a local c2 to contact with the medial wall of tremulous pulse, melts like this 9 the stable strong point that will mainly rely on each absolute construction 8 to contact with the medial wall of tremulous pulse and form.As shown in figure 26, be shaped as S shape after 5 deformation of controllable bending tune, the controllable bending tune 5 of solid line part has represented a kind of situation of S shape, under this shape, controllable bending tune 5 preferred lengths are 80--160mm, controllable bending tune 5 will have three local c1, c2 contacts with the blood vessel medial wall with c3, its c1 contacts with the medial wall of renal artery a, and c2, the blood vessel wall contact that c3 is relative with ventral aorta b, so more be conducive to when melting stablely to melt 9, controllable bending tune 5 this moment preferably and one of them absolute construction 8 at grade, like this for 9 situation as detecting electrode that melt are only arranged on the absolute construction 8, can detecting electrode 19 be set at c1, melt like this 9 or absolute construction 8 on detecting electrode 19 will form a granting electric pulse with detecting electrode 19 on the controllable bending tune 5, one receives electric pulse, certainly for adapting to the renal artery of different tube diameters, a plurality of ring-types can be set near c1 receive detecting electrode 19, certainly for paired electric pulse granting and the situation of collecting electrode have been arranged on the absolute construction 8, c1 can not arrange detecting electrode 19; The controllable bending tune 5 of dotted portion has represented the situation of another kind of S shape, in this case, controllable bending tune 5 preferred lengths are 70--140mm, and controllable bending tune 5 will only have c2 to contact with the medial wall of tremulous pulse with c3, situation than solid line is slightly poor, but processing technology is relatively simple.
As the case may be, the technical staff can be merged the design of above-mentioned these sections of melting 6 and controllable bending tune 5, improvement and cross-reference, and these equivalences change and modify and fall into equally this utility model claim limited range.
ACTIVE CONTROL deformation or and Passive Control deformation can occur in controllable bending tune 5, absolute construction 8 and guiding catheter 7.Wherein the controllable bending tune 5, the ACTIVE CONTROL deformation of absolute construction 8 and guiding catheter 7 refers to controllable bending tune 5, absolute construction 8 and guiding catheter 7 are in the situation that pass through indirectly in real time control controllable bending tune 5 without external force direct effect or transmission, the variation of absolute construction 8 and guiding catheter 7 internal force and the deformation that occurs, for example: controllable bending tune 5, absolute construction 8 and guiding catheter 7 contain intellectual material (such as marmem), by the outer control to intellectual material temperature etc. of ablation catheter 1 and guiding catheter 7, realize real time altering controllable bending tune 5, absolute construction 8 and guiding catheter 7 in vivo with external deformation form.The Passive Control deformation of controllable bending tune 5, absolute construction 8 and guiding catheter 7 then refers to make in the external force of controllable bending tune 5, absolute construction 8 and guiding catheter 7 by directly or indirectly real-time control action the deformation of controllable bending tune 5, absolute construction 8 and guiding catheter 7 generations; For example be fixed on the guide wire 11 on the controllable bending tune 5 so that deformation occurs controllable bending tune 5 by tractive, be fixed on the traction fiber 10 on the absolute construction 8 so that deformation occurs absolute construction 8 by tractive, be fixed on the guide wire 70 on the guiding catheter 7 so that deformation occurs guiding catheter 7 by tractive; Again for example in the propelling movement process, melting paragraph header end 17, to contact the compliance that after the blood vessel wall controllable bending tune 5 is occured crooked; Again for example controllable bending tune 5, absolute construction 8 and guiding catheter 7 contain can be by the material of attraction, by externally-applied magnetic field so that controllable bending tune 5, absolute construction 8 and guiding catheter 7 bend.Ablation catheter 1 and guiding catheter 7 can have prefabricated deformation, for example can in advance controllable bending tune 5 be preset to the state of certain direction bending when external manufacturing, so that the section of melting 6 can enter renal artery smoothly; Prefabricated deformation also can realize external prefabricated deformation being adjusted by add the material with shape memory function in ablation catheter 1 and guiding catheter 7, for example: in controllable bending tune 5, add marmem, can first it be made C shape in advance at external bending shape crooked, when needs controllable bending tune 5 changes bending shape, can again it be taken out again externally making controllable bending tune 5 make the curved pattern of other shapes by variations in temperature.
ACTIVE CONTROL deformation for absolute construction 8, controllable bending tune 5 and guiding catheter 7, at present preferred intellectual material, wherein better with the comparatively ripe marmem of technology, certainly can select the intellectual materials such as electroactive polymer, magnetic living polymer according to specification requirement.Marmem being designed to the structures such as spiral type, " Z " font, " G " font implants in absolute construction 8 and the controllable bending tune 5 or in their tube wall, and in guiding catheter 7 tube walls, by the temperature of the adjustable shape memorial alloys such as electric current, reach the purpose of control absolute construction 8, controllable bending tune 5 and guiding catheter 7 deformation.Figure 27 has shown that this utility model adopts marmem to realize the situation of ACTIVE CONTROL deformation.Shown in Figure 27 A, marmem is designed to spiral type, such as spring-like, when when heating energising, straight spiral in shape memorial alloy under the room temperature will bend, and this kind structure generally is used for the situation of bend in one direction and distorted shape bending.Shown in Figure 27 B, marmem is designed to " Z " font and " G " font.Shown in Figure 27 C, according to the original shape of marmem, when the energising heating, " Z " character form structure can occur to stretch or compression.Figure 27 D has shown the crooked method of multidirectional control that realizes, be about on three different directions of " Z " character form structure difference implantation catheter wall, when " Z " character form structure on when heating energising some directions, conduit will bend to some directions, when " Z " character form structure on when heating energising adjacent direction, conduit will " Z " character form structure generation direction with joint efforts bend on both direction, certainly according to practical situation, can adjust the quantity of " Z " character form structure implantation catheter wall, directions etc. are to realize control conduit both direction and the Bending Deformation more than the both direction.Figure 27 E has shown the structure of the marmem when conduit is semicircle, total is semicircular helical form, spiral both sides can arrange two Metallic rod a, play the semicircular helicoidal structure of restriction to two lateral bends, therefore when the energising heating, this semicircular helicoidal structure will bend intelligently forward or backward.Figure 27 F has shown the structure of the another kind of marmem when conduit is semicircle, " Z " character form structure can arrange bent side or the flat side capable with semicolumn, therefore when the energising heating, " Z " character form structure occurs to stretch or compression, so that conduit is crooked forward or backward.Because when marmem was heated, temperature generally was higher than human body temperature, so the outer surface of conduit is preferably selected adiabator or heat insulating construction.The project organization of marmem never is confined to spiral type, " Z " font, " G " character form structure, can also design according to actual needs other structures.Be the situation of other shapes for conduit, can copy marmem illustrated in Figure 27 to realize that the design of conduit ACTIVE CONTROL deformation designs.Also can use the traction fiber 10 in the line traffic control structure described later, guide wire 11, guide wire 70 instead the marmem manufacturing in addition, also can realize the control to the deformation of ablation catheter 1, guiding catheter 7 by traction fiber 10, guide wire 11, guide wire 70 length variations.
For the Passive Control deformation of absolute construction 8, controllable bending tune 5 and guiding catheter 7, preferably adopt the design of line traffic control structural design and magnetron configuration.On ablation catheter 1, the line traffic control structural design is or/and the variation of stress by the traction fiber 10 that is connected in absolute construction 8 or guide wire 11 tension force that are connected in controllable bending tune 5, so that Passive Control deformation occurs in absolute construction 8 or controllable bending tune 5, but preferred by increasing traction fiber 10 or/and the tension force of guide wire 11, i.e. tractive traction fiber 10 and push ablation catheter 1 other parts except traction fiber 10 or/and tractive guide wire 11 and propelling movement ablation catheter 1 other parts except guide wire 11; Similarly, or/and the variation of stress by guide wire 70 tension force of traveling in guiding catheter 7 tube walls at guiding catheter 7 control structure of reaching the standard grade, so that Passive Control deformation occurs in guiding catheter 7, but preferred tension force by increase guide wire 70, i.e. tractive guide wire 70 and propelling movement guiding catheter 7 other parts except guide wire 70.The traction fiber 10 main deformation of being responsible for control absolute construction 8, sometimes ablation catheter 1 also can lead, but traction fiber 10 when the section of melting 6 traveling in absolute construction 8, also but traveling is outside absolute construction 8, but other parts at the ablation catheter 1 except the section of melting 6, traction fiber 10 preferred travelings are in ablation catheter 1, and traction fiber fixed disk 205 final and on the joystick 2 links to each other.The effect of guide wire 11 mainly is to adjust ablation catheter 1 at endovascular direction of travel, guide wire 11 preferred travelings are in controllable bending tune 5, in ablation catheter 1, and guide wire fixed disk 204 final and on the joystick 2 links to each other in other parts of the ablation catheter 1 except controllable bending tune 5 also preferred traveling.The effect of guide wire 70 mainly is to adjust guiding catheter 7 at endovascular direction of travel, and guide wire 70 preferred travelings and finally are connected with guiding catheter control handle 27 or joystick 2 in guiding catheter 7 tube walls.The bending direction of the main as required control of the quantity of guide wire 11 and controllable bending tune 5 have or not and preset deformation and decide, the quantity of guide wire 11 preferably is less than or equal to the quantity of the bending direction of required control, table 1 enumerated guide wire 11 quantity and controlling party to have or not the relation that presets deformation.In the situation that satisfy traction fiber 10, guide wire 11, guide wire 70 major functions, preferably reduce the quantity of traction fiber 10, guide wire 11, guide wire 70 as far as possible.Magnetron configuration design mainly is by can being added magnetic attraction under the action of a magnetic field or repulsion so that the Passive Control deformation occur for absolute construction 8, controllable bending tune 5 and guiding catheter 7 by the material of attraction in absolute construction 8, controllable bending tune 5 and the guiding catheter 7, thereby realizes the function of various piece.Joystick 2 and guiding catheter control handle 27 will be at the detailed descriptions of back.

Figure 28, Figure 29, Figure 30, Figure 31 are take two absolute construction 8 as example, have shown that absolute construction 8 far-ends are connected to form the main feature of the line traffic control structure when melting paragraph header end 17; Wherein Figure 28, Figure 29 have shown the line traffic control structure when controllable bending tune 5 is C shape curved design, and Figure 30, Figure 31 have shown the line traffic control structure when controllable bending tune 5 is S shape curved design.Such as Figure 28 A, Figure 30, shown in Figure 31, when traction fiber 10 travelings when absolute construction 8 is outer, the head end fixing point 110 of traction fiber 10 preferably is arranged at and melts paragraph header end 17, and the major axis centrage traveling of the edge section of melting 6, also preferably traveling is in the major axis centrage in the ablation catheter 1 except the section of melting 6 for traction fiber 10, and this moment preferably only need to a traction fiber 10.Such as Figure 28 B, Figure 30, shown in Figure 31, when traction fiber 10 travelings when absolute construction 8 is interior, the head end fixing point 110 of traction fiber 10 preferably is arranged at and melts paragraph header end 17 (comprising end points) to the absolute construction 8 between melting 9, shown in the figure is to be fixed in the situation that melts paragraph header end 17, traction fiber 10 can be along the part traveling of each absolute construction 8 by the section of melting 6 major axis centrages, situation for two absolute construction 8 shown in the figure, absolute construction 8 is interior all to arrange a traction fiber 10, for the situation more than two absolute construction 8, at least two traction fibers 10 can be separately positioned in the relative absolute construction 8 or a traction fiber 10 all be set each absolute construction 8 is interior; Such as Figure 28 A, Figure 30, shown in Figure 31, these traction fibers 10 preferably are merged into one the ablation catheter 1 except the section of melting 6 is interior, and preferably traveling in the major axis centrage of 1 section of these ablation catheter.As shown in figure 29, traction fiber 10 also can be along the part traveling of each absolute construction 8 away from the section of melting 6 major axis centrages, and this moment, traction fiber 10 can be brought into play the effect of guide wire 11; Situation for two absolute construction 8 shown in Figure 29, each absolute construction 8 is interior all to arrange a traction fiber 10, for the situation more than two absolute construction 8, can be with at least two traction fibers 10 respectively in relative absolute construction 8, perhaps a traction fiber 10 all is set each absolute construction 8 is interior; As shown in figure 29, be used as the traction fiber 10 of guide wire in the ablation catheter 1 interior preferably respectively traveling except the section of melting 6, nonjoinder becomes one, and preferably traveling in 1 section of these ablation catheter accordingly away from the part of major axis centrage, so if increase simultaneously the tension force of all traction fibers 10 this moment or in the situation that absolute construction 8 has prefabricated deformation to increase simultaneously the effect of the traction fiber that traction fiber 10 stress then bring into play, if increase respectively the tension force of each traction fiber 10 or increase respectively the effect that each traction fiber 10 stress is then brought into play guide wire.Such as Figure 28 B, Figure 30, shown in Figure 31, for line traffic control structure shown in Figure 29, the controllable bending tune 5 preferred C shape curved design that adopt, Figure 29 A has shown in the C shape curved design design form of dotted portion among Figure 25, and Figure 29 B has shown in the C shape curved design scheme design form of solid line part among Figure 25.Be connected in the situation that melts paragraph header end 17 for absolute construction 8 far-ends, for handled easily, prefabricated deformation preferably is not set, namely the initial deformation of absolute construction 8 is not made the scatter state of protuberance of mid portion, Figure 28 A, Figure 28 B will mainly rely on the tension force (being tractive traction fiber 10 or front ablation catheter 1 other parts except traction fiber 10 of sending) that increases traction fiber 10 to realize that absolute construction 8 mid portions scatter to swell finally to make to melt 9 and contact with blood vessel wall this moment; If certainly the initial deformation of absolute construction 8 being made mid portion scatters when swelling, Figure 28 A, Figure 28 B will mainly rely on stress (namely pushing traction fiber 10 or rollback ablation catheter 1 other parts except traction fiber 10) realization absolute construction 8 mid portions that increase traction fiber 10 to draw close each other and then so that melt 9 and separate with blood vessel wall, if to melt 9 and contact closelyr with blood vessel wall in order to make, also can increase the tension force of traction fiber 10.As shown in figure 28, when controllable bending tune 5 adopts the C shape curved design of solid line part among Figure 25, the head end fixing point 111 of guide wire 11 preferably is arranged on controllable bending tune 5 near the place of the section of melting 6, and should be as required the crooked corresponding centrifugal fixed position of set direction, guide wire 11 preferably traveling and has a guide wire 11 and traction fiber 10 coplines at least in controllable bending tune 5.Shown in Figure 29 A, when controllable bending tune 5 adopts the C shape curved design of dotted portion among Figure 25, can adopt the function of traction fiber 10 performance guide wires 11, and the head end fixing point 110 of traction fiber 10 is arranged on melts paragraph header end 17; Certainly C shape warp architecture shown in Figure 29 also can adopt the fixed form of guide wire shown in Figure 28 11, this moment traction fiber 10 arrange and traveling also can arrange according to design illustrated in Figure 28.Shown in Figure 30 A, Figure 31 A, when controllable bending tune 5 adopts S shape curved design, on the basis that C shape curved design guide wire illustrated in Figure 28 11 is arranged, can add in addition a guide wire 11' at the far-end that needs form second bending of S shape bending and be fixed in this, this guide wire 11' is the corresponding centrifugal fixed position of set direction of bending as required, and best and at least one guide wire 11 copline; Shown in Figure 30 B, Figure 30 C, Figure 31 B, Figure 31 C, also can not increase the quantity of guide wire 11, by the traveling path of adjusting guide wire 11 and the hardness distribution (aftermentioned) of passing through to adjust controllable bending tune 5, so that can realize that by one of them guide wire 11 S shape is crooked; Wherein Figure 31 represents is the line traffic control structural design of the S shape curved design of solid line part among Figure 26, is the line traffic control structural design of the S shape curved design of dotted portion among Figure 26 and wherein Figure 30 represents.
Figure 32, Figure 33, Figure 34, Figure 35 have shown the deformation that promotes ablation catheter 1 and guiding catheter 7 in this utility model by the mode of structural design.This mode by structural design promotes the deformation of ablation catheter 1 and guiding catheter 7 and does not require that the hardness of manufactured materials of various piece itself is different.
Such as Figure 32 A, shown in Figure 32 B, in ablation catheter 1 inside the chicken ribs spline structure shown in Figure 32 A and Figure 32 B is set, be that interval d5 is the structure shown in Figure 32 B apart from a cross section is set, the part that this structure bend represents is had certain elastic Material Filling, preferred high molecular polymer, white space a1 will form a chamber ablation catheter 1 is interior, be mainly used in the traveling of traction fiber 10 and the traveling of counter-bending deformation structures relatively poor or easy and traction fiber 10 or guide wire 11 entanglement, wire for example, conduit, optical fiber etc., certainly white space a1 is not limited to circle, also be not limited to a chamber is only arranged, according to circumstances can be arranged to other shapes (for example oval, rectangle etc.), the respectively different member of traveling of more chamber also can be set.Shown in Figure 32 A, Figure 32 B, white space b1 also will form a chamber in ablation catheter 1, be mainly used in guide wire 11 or/and the traveling of traction fiber 10, certainly white space a1 is not limited to semicircle, also be not limited to a chamber is only arranged, according to circumstances can be arranged to other shapes (such as ellipse, rectangle etc.), the respectively different member of traveling of more chamber also can be set, be independent of each other if wish traction fiber 10 or guide wire 11, traction fiber 10 and guide wire 11 can be distinguished traveling in different chamber.Shown in Figure 32 A, owing to the arcuate structure in d3 and the d4 institute inclusion region among shortage Figure 32 B in the included zone of d5, therefore on y direction, the included zone of each d5 will easily bend, and the bending in the zone that all d5 are included will make structure shown in Figure 32 A form integrally bending; Take controllable bending tune 5 as example, if the prefabricated deformation bending direction of controllable bending tune 5 is the indicated direction of arrow among Figure 32 A, tractive will so that controllable bending tune 5 rightabout shown in the arrow in Figure 32 A bends, so just have been realized the bending of both direction near the guide wire 11 of d4 traveling by a guide wire 11 from white space b1 so.Similarly, shown in Figure 32 C, the white space that b1 sample among two Figure 32 B is set in the included zone of d3, d4, d3', d4' is white space b1, b2, and this moment white space a1 between white space b1, b2, be in the included zone of d1 (mainly in the zone that d2 and d2' surround), structure among Figure 32 A in the included zone of d6 will be substituted by the structure shown in Figure 32 C, and the structure in the included zone of d5 will be the extension of the structure in the included zone of d1 among Figure 32 C among Figure 32 A; White space a1 will form a chamber ablation catheter 1 is interior, be used for the relatively poor structure of traction fiber 10, counter-bending deformation or easily with the traveling of the structure of traction fiber 10 or guide wire 11 entanglement, certainly white space a1 is not limited to ellipse, and also being not limited to only has a chamber; White space b1 and b2 also will form two chambers in ablation catheter 1, be mainly used in guide wire 11 or/and the traveling of traction fiber 10, certainly white space b1 and b2 are not limited to semicircle, also be not limited to a chamber is only arranged, be independent of each other if wish traction fiber 10 and guide wire 11, traction fiber 10 is with in guide wire 11 can be distinguished the different chamber of traveling; Owing in the included zone of d5, lacking the arcuate structure in d3, d4 among Figure 32 C, d3', the d4' zone institute inclusion region, therefore on y direction, the included zone of each d5 will easily bend under the effect of traction fiber 10 or guide wire 11, the bending in the zone that all d5 are included will make structure shown in Figure 32 A form integrally bending, this moment is because the d5 both sides all lack supporting construction, therefore compound bending can occur, and pass through to adjust the large young pathbreaker of white space b1 and b2 so that different to the complexity of both direction bending; Certainly also can the b1 sample white space that three Figure 32 B illustrate be set at three different directions similarly, with the bending of at least three directions of realization, and this project organization can also be by that analogy.Shown in Figure 32 D, Figure 32 E, when the cross section of ablation catheter 1 some part is not circle, the chicken ribs spline structure can be realized in these ablation catheter 1 parts equally, Figure 32 D, Figure 32 E have illustrated the implementation of chicken ribs spline structure in other shapes except circle as an example of semicircular structure example, different according to the position that the different white space a1 of bending direction and b1 arrange.For example, shown in Figure 32 D, white space b1 is arranged in the left side of white space a1, structure among Figure 32 A in the included zone of d6 will be substituted by the structure shown in Figure 32 D, and the structure in the included zone of d5 will be the extension of the structure in the included zone of d1 among Figure 32 D among Figure 32 A, like this traveling under the tractive of the traction fiber 10 of white space b1 or guide wire 11 whole stereochemical structure will be easily to white space b1 lateral bend or weaken to the degree of white space a1 lateral bend; Shown in Figure 32 E, white space b1 is arranged in the right of white space a1, structure among Figure 32 A in the included zone of d6 will be substituted by the structure shown in Figure 32 E, and the structure in the included zone of d5 will be the extension of the structure in the included zone of d1 among Figure 32 E, like this traveling under the tractive of the traction fiber 10 of white space b1 or guide wire 11 whole stereochemical structure will be easily to white space b1 lateral bend or weaken to the degree of white space a1 lateral bend.In structure shown in Figure 32, by changing white space a1, the size of b1, b2, quantity, and by changing the size of d1, d2, d3, d4, d5, d6, can realize the difference of each section hardness, for example a certain section in Figure 32 A widened d1, dwindling d3 or d4 will be so that this section be not easy deformation, more for example a certain section widen d5 will so that, the easier deformation of this section; Can realize that by the relative position that changes the interior white space a1 of different sections and b1 different sections are non-crooked in the same way, for example with the Lower Half horizontal rotary turnback of Figure 32 structure that A illustrates, with so that the arrow side of Lower Half white space b1 in Figure 32 A, the structure after improving like this will help to realize that S shape is crooked.In a word, the essence of chicken ribs spline structure is by reducing or/and increase the internal structure of some conduit segment and then optionally reduce or/and improve the counter-bending ability of a certain side of the little intrasegmental part of some conduit or a few sides, so that conduit is easier to be crooked or/and form some bending shape to some direction.
Figure 33 has shown that another kind of mode by structural design changes the design that hardness distributes and then promotes the multi-direction bending of ablation catheter 1 and guiding catheter 7 in this utility model.This structural design needing to be preferred for the situation of control controllable bending tune 5 multi-direction bendings.Wherein Figure 33 A is the schematic perspective view of this structure, Figure 33 B is the cross sectional representation of the included zone level center line of this structure d6, it also is the sectional view that the cc2 cross section amplifies among Figure 33 C, Figure 33 D, Figure 33 C and Figure 33 D are the vertical section schematic diagram of this structure, also are the sectional view of cc1 cross section among Figure 33 B.The thinking of this project organization is similar to the chicken ribs spline structure, also is in interval d5 distance the structure that a d6 zone comprises to be set, and shown in Figure 33 A, Figure 33 C, Figure 33 D, whole stereochemical structure is that the biconvex disk overlaps.As shown in figure 33, the part that this structure bend or horizontal line represent is had certain elastic Material Filling, preferred high molecular polymer.Shown in Figure 33 A and Figure 33 B, disc centre white space a1 will form a chamber ablation catheter 1 is interior, be mainly used in traction fiber 10, relatively poor structure or the traveling easy and structure that guide wire 11 tangles of counter-bending deformation, certainly white space a1 is not limited to circle, also be not limited to a chamber is only arranged, according to circumstances can be arranged to other shapes (such as ellipse, rectangle etc.), the respectively different member of traveling of more chamber also can be set; White space b1, b2, b3, b4 are at the ablation catheter 1 interior pipeline that will form four interruptions around the disk, be mainly used in guide wire 11 travelings, the caliber of this pipeline is d3, but when biconvex disk overlay structure is used for other parts also traveling traction fiber 10 etc. of white space b1, b2, b3, b4; Be independent of each other if wish traction fiber 10 and guide wire 11, traction fiber 10 and guide wire 11 can be distinguished traveling in different chamber.Shown in Figure 33 C, because adjacent two biconvex disks are relative inclined-plane in the zone that d4 comprises, exist certain for d7, therefore under the effect of the guide wire 11 on certain direction or traction fiber 10, overall structure will easily bend, under the effect, overall structure can easily bend to more direction in several guide wires 11 or traction fiber 10; Certain whole design is not limited to four b1 sample white spaces (b1, b2, b3, b4), can increase and reduce according to the needs of bending direction; The setting position of b1 sample white space also can be different, can regulate like this tension force and the stress intensity of the required guide wire 11 of overall structure deformation or traction fiber 10, for example some b1 sample white space can more close white space a1, and the guide wire 11 that needs of the bending that makes progress of the party or the tension force of traction fiber 10 will be larger like this; B1 sample white space also can be different in the position that each biconvex disk arranges, perhaps same guide wire 11 or traction fiber 10 can be in total traveling in different b1 sample white spaces, can adjust like this bending shape of total, realize distortion etc.Adjacent two flying saucer sample disks can arrange the d5 zone shown in Figure 33 D simultaneously, so that overall structure more easily bends.By changing white space a1, b1, b2, the size of b3, b4, quantity, and the size that changes d1, d2, d3, d4, d5, d6, d7, can make each section hardness difference, for example a certain section in Figure 32 A widened d1, dwindling d4 will be so that this section be not easy deformation, again for example a certain section widen d5 will so that, this section easier deformation.In addition, this structural design is equally applicable to the situation of some other cross section non-circular structure, such as semicircle etc., but need to consider that dissymmetrical structure is on the impact of guide wire 11, traction fiber 10 and the hardness of structure own this moment.Similarly, the essence of biconvex disk overlay structure also is by reducing or/and increase the internal structure of some conduit segment and then optionally reduce or/and improve the counter-bending ability of a certain side of the little intrasegmental part of some conduit or a few sides, so that conduit is easier to be crooked or/and form some bending shape to some direction.
Figure 34 has shown that another kind of the distribution by change structure design and then change hardness makes the crooked design that more easily realizes in this utility model.This project organization is the implementation of chicken ribs spline structure in hollow tubular structure, and this kind structure optimization is used for hollow tubular structure (such as guiding catheter 7 etc.).This structure mainly by change metal gauze in ablation catheter 1 and guiding catheter 7 tube walls in different conduit segments arrange or ablation catheter 1 and the thickness of guiding catheter 7 tube walls in different conduit segments realizes by changing, certainly metal gauze described here is construed as the project organization of reinforcing duct wall hardness, such as also can being macromolecular material net etc., therefore the essence of this kind design is by reducing or/and increase the structure of some conduit segment tube wall and then optionally reduce or/and improve a certain side of some conduit segment tube wall or the counter-bending ability of a few sides, so that conduit is easier to be crooked or form some bending shape to some direction.Figure 34 changes metal gauze in ablation catheter 1 or guiding catheter 7 tube walls arranging in different conduit segments to describe for example.Shown in Figure 34 A, netting twine represents metal gauze among the figure, can see from the lower-left figure of Figure 34 A, metal gauze in the duct wall is to cover duct wall fully, can see from the picture left above of Figure 34 A, does not have metal gauze in the side pipe wall of conduit, two little spacer segments of conduit are stacked together, structure shown in the right figure of pie graph 34A, owing to do not have metal gauze in the side pipe wall of a bit of conduit of top, so the easier curving to there not being metal gauze of conduit.Certainly also be not limited to the design that does not have metal gauze in the side pipe wall of conduit, shown in Figure 34 D, between two conduit segments that complete metal gauze arranged, four S shape tinsel f1 are arranged, f2, f3, f4, can be at f1, between f2 and f3, metal gauze is set between f4, and at f2, between f3 and f1, metal gauze is not set between f4, so easier two lateral bends to there not being metal gauze of conduit, the metal gauze of half in like manner also can only be set between every adjacent two S shape tinsels, the easier four direction to there not being metal gauze of conduit is crooked like this, can also only have four S shape tinsels and not have metal gauze, whole like this conduit will be easily crooked to a plurality of directions, if cooperate the guide wire 70 on the four direction, traction fiber 10 or guide wire 11 can realize controlling multi-direction bending.Also be not limited in addition a certain side of some conduit segment tube wall or the situation that a few side does not have metal gauze, the modes such as the aperture that this can be by changing metal gauze, density, width wiry realize that a certain side or a few side of catheter wall of some conduit segment is soft or hard than other catheter walls; According to circumstances S shape quantity wiry can be adjusted, and simultaneously S shape tinsel also can be other forms, such as " Z " shape etc.The structure of Figure 34 A can be arranged according to the side sight figure shown in Figure 34 B, and the bending direction of whole like this run will be consistent; The structure of Figure 34 A can be arranged according to the side sight figure shown in Figure 34 C, the bending direction of whole like this run top and the bottom is inconsistent, just can realize complicated bends by a guide wire 70 in this way, the zone of for example guide wire 11 d3 and d3' from Figure 34 C being intersected is passed the bending of realizations S shape.Shown in Figure 34 B and Figure 34 C, can also change the complexity of each section of conduit bending by the width of adjusting d1, d3, d3', d4, d5.Total also is not limited to the situation that conduit cross section is circle in addition, conduit cross section still can design according to this thinking when being the shape such as semicircle, square, but need to consider that these shapes are on the impact of traction fiber 10, guide wire 11, guide wire 70 and the hardness of chicken ribs spline structure own this moment.
Figure 32, Figure 33, the hardness that the mode of passing through structural design that Figure 34 is shown changes ablation catheter 1 and guiding catheter 7 distributes, can also realize by the hardness that changes manufactured materials, for example the cross section of each section of conduit can all be designs of Figure 32 B, but d3 on the cross section of some section, the included regional manufactured materials of d4 is hard than other sections, these sections will be not easy to bend so, again for example in the structure shown in Figure 33 D, the manufactured materials of second biconvex disk is soft with the 3rd than first, will more easily bend in the place of second flying saucer sample disk so.
Figure 35 has shown in this utility model by design of hinges structure 15 and joint spline structure and has realized that ablation catheter 1 some part more easily bends.Figure 35 A is connected in the situation that melts paragraph header end 17 take two absolute construction 8 to describe as the mentality of designing of example to hinge arrangement, therefore also can copy design for other situations.Shown in Figure 35 A, absolute construction 8 above figure melt 9 around be provided with two hinge arrangements 15, like this when the absolute construction 8 above traction fiber 10 effect figure below bends, two hinge arrangements 15 will at first bend, form a bit of horizontal segments 15 of two hinge arrangements, conveniently melt 9 and contact with blood vessel wall.Figure 35 B, Figure 35 C have shown the situation after hinge arrangement 15 feasible design schemes amplify.Shown in Figure 35 B, hinge arrangement 15 is blocked mutually by the local complementation that g1 and g2 partly cross, and guarantees two part normal rotation of g1 and g2 and do not separate mutually under the interting of breechblock e.Similarly, shown in Figure 35 C, hinge arrangement 15 by g1 and g2 partly cross local complementary complete, and under the interting of breechblock e, guarantee two part normal rotation of g1 and g2 and do not separate mutually.Hinge arrangement 15 shown in Figure 35 B also can arrange in the place that g1 and g2 partly cross latch to be guaranteed two part normal rotation of g1 and g2 with draw-in groove and not to separate mutually.Different according to the direction of bending and traction fiber 10 model of action, the traction fiber 10 shown in the dotted line can select different paths by hinge arrangement 15 among Figure 35 B, Figure 35 C, for example for by the tension force that increases traction fiber 10 g1 being bent downwardly, then the preferred traveling of traction fiber is in the side by bending direction of hinge arrangement 15, it is the below of hinge arrangement 15, as for the stress by the increase traction fiber g1 being bent downwardly, then the preferred traveling of traction fiber is in a side of the back of the body bending direction of hinge arrangement 15, the i.e. top of hinge arrangement 15.Certainly hinge arrangement never is confined to two kinds of designs shown in the figure, as long as pass through two parts of breechblock or breechblock spline structure connecting duct, and realizes that conduit all is fine in the design of breechblock or the place's bending of breechblock spline structure.Can adopt in addition the joint spline structure shown in Figure 35 D, ball and socket joint h1 is held by articular cavity h2, and rotates in the h2 of joint, and the shape of ball and socket joint h1 and articular cavity h2 has determined rotation direction and the slewing area of joint spline structure; If ball and socket joint h1 is cylindrical, articular cavity h2 also is the cylindrical shell of half opening, then only has the rotation of both direction, if ball and socket joint h1 is spherical, articular cavity h2 is hemispherical Shell, then can realize multiple-directional rotating, and slewing area is larger; Traction fiber 10 or guide wire 11 preferably pass through around ball and socket joint h1 and articular cavity h2, do not pass ball and socket joint h1 and articular cavity h2, and traction fiber 10 or guide wire 11 that control joint spline structure rotates preferably pass through from joint spline structure rotation direction side, the joint spline structure can not rotating side can be used for other linear passing through, for example ball and socket joint h1 is cylindrical, when articular cavity h2 also was the cylindrical shell of half opening, traction fiber 10 or guide wire 11 preferably passed through from the joint spline structure upper and lower shown in Figure 35 D; The pipe-like structure also can be set on this external ball and socket joint h1 and the articular cavity h2 to be used for passing through member in the spline structure of joint.The hinge arrangement 15 of this joint spline structure in also can alternate figures 35A.
Figure 36, Figure 37 are that the far-end take two absolute construction 8 is connected in and melts paragraph header end 17 as example, and how having shown in this utility model distributes by the hardness of adjusting absolute construction 8 more easily realizes the deformation of design.As shown in figure 36, two absolute construction 8a, 8b bending shape are symmetrical each other, for conveniently outwards protruding for semi-cylindrical two absolute construction 8a, 8b, Figure 32 can be adopted or/and chicken ribs spline structure illustrated in Figure 34, when adopting chicken ribs spline structure illustrated in Figure 32, absolute construction 8 can adopt the design shown in Figure 32 D, wherein the form of the cross section shown in the dotted line cc is preferably shown in Figure 32 D, if traction fiber 10 travelings this moment in (shown in Figure 36 B) in the absolute construction 8 traveling in the white space b1 shown in Figure 32 D; When adopting chicken ribs spline structure illustrated in Figure 34, the blank parts in the absolute construction 8 is interpreted as the structural rigidity that absolute construction 8 tube walls keep at a certain distance away and reduces, such as by removing metal gauze, changing the density of metal gauze etc.As shown in figure 37, the bending shape of two absolute construction 8 also can be asymmetric, and this is very necessary for absolute construction 8 during more than two, and it helps so that ablation points is on the different renal artery cross sections; Similar with chicken ribs spline structure shown in Figure 36, design shown in Figure 37 also can adopt Figure 32 or/and chicken ribs spline structure design illustrated in Figure 34, in order to realize different bending shapes, can realize by the arrangement of adjusting chicken ribs spline structure on each absolute construction 8 difference of each section hardness, the local hardness larger in curvature is preferably less, more easily realizes crooked.The blank parts of absolute construction 8a, 8b represents the less part of hardness on each absolute construction 8 among Figure 37, therefore the hardness that can change the chicken ribs spline structure such as the size by adjusting absolute construction 8a, the upper blank parts of 8b, form, branch's density distributes, and then the change bending shape.Shown in Figure 37 A, Figure 37 B, in absolute construction 8a, melt and melt 9 greatlyr to the part curvature that melts paragraph header end 17 among a part of 9 to absolute construction 8a tail ends and the absolute construction 8b, so blank parts is also larger and closeer.Similarly, among Figure 37 C, Figure 37 D, latter two melts 9 distances to the section of melting 6 major axis centrages and equates in order to realize absolute construction 8 deformation, in the situation that two absolute construction 8 equal in length, absolute construction 8b has been designed to that near-end is not flexible and far-end and mid portion easily bend, therefore far-end and the mid portion blank parts of absolute construction 8b are also more intensive, make it more flexible.Among Figure 37 E, Figure 37 F, absolute construction 8 deformation latter two melt 9 unequal to the distance between center line of the section of melting 6 major axis, in the situation that two absolute construction 8 equal in length, the length of the most obvious part of median rise of absolute construction 8 on two absolute construction 8 is different, the most obvious part of absolute construction 8b median rise is longer, this just requires other part curvature of absolute construction 8b larger, more flexible, so the blank parts of the far-end of absolute construction 8b and near-end is also larger, more intensive.As shown in figure 37, the shape of blank parts also can be changeable, can be the shape shown in Figure 37 A, Figure 37 B, also can be the shape shown in Figure 37 C, Figure 37 D, Figure 37 E, Figure 37 F, and the technical staff can also be according to concrete other shapes of actual design certainly.Figure 36, Figure 37 carry out the design explanation as an example of two absolute construction 8 example, therefore be not limited to the situation of two absolute construction 8, and be applicable too for the situation more than two absolute construction 8.The blank parts on the absolute construction 8 is interpreted as the structural rigidity reduction that absolute construction 8 keeps at a certain distance away among Figure 36, Figure 37 in addition, and this hardness descends and not only can realize by the mode of change structure design can realizing by the mode that changes material hardness equally.Need absolute construction 8 to form the situation of other bending shapes for the technical staff, can the blank parts of absolute construction 8 among Figure 36, Figure 37 be adjusted accordingly.
Figure 38, Figure 39 have shown this utility model is how by the hardness distribution of adjusting controllable bending tune 5 design deformation more easily to be realized; Wherein Figure 38 has shown the structure when controllable bending tune 5 is C shape curved design, and Figure 39 has shown the structure when controllable bending tune 5 is S shape curved design.Blank parts among Figure 38, Figure 39 on the controllable bending tune 5 is interpreted as the structural rigidity reduction that controllable bending tune 5 keeps at a certain distance away, this hardness descends and not only can realize by the mode of change structure design also can realizing by the mode that changes material hardness, and the hardness distribution of the changes controllable bending tunes 5 such as size that therefore can be by adjusting blank parts on the controllable bending tune 5, form, branch's density makes it more flexiblely become needed form.When controllable bending tune 5 is C shape curved design, the structure of the quantity design controllable bending tune 5 of preferred as required bending direction, Figure 38 A, Figure 38 B, Figure 38 C describe with the example that is bent into that guide wire 11 is controlled a direction by the mode that increases tension force, and wherein Figure 38 B, Figure 38 C are the side view after the chicken ribs spline structure of controllable bending tune 5 amplifies.Shown in Figure 38 A, guide wire 11 head end fixing points 111 preferably are arranged on the local of the controllable bending tune 5 close sections of melting 6 and are positioned at the eccentric position of bending direction side, similar with the design of Figure 36, absolute construction 8 illustrated in Figure 37, controllable bending tune 5 also preferably adopts the chicken ribs spline structure; When adopting chicken ribs spline structure shown in Figure 32, controllable bending tune 5 can adopt the design shown in Figure 32 A and Figure 32 B, wherein the section morphology of the cross section shown in the dotted line cc1 is preferably shown in Figure 32 B among Figure 38 B, if this moment, guide wire 11 travelings were in controllable bending tune 5, the white space b1 that illustrates in Figure 32 A and Figure 32 B of preferred traveling then, also be the d3 part among Figure 38 B, Figure 38 C, certainly according to circumstances guide wire 11 also can traveling outside controllable bending tune 5 or the part traveling outside controllable bending tune 5; When adopting chicken ribs spline structure shown in Figure 34, the blank parts of controllable bending tune 5 is interpreted as the structural rigidity decline that controllable bending tune 5 tube walls keep at a certain distance away among Figure 38 A, Figure 38 B, Figure 38 C, such as by removing metal gauze, changing the density of metal gauze etc., guide wire 11 preferred travelings are in the curved side of controllable bending tune 5; If need crooked direction and the opposite direction (being direction shown in the arrow ao2) shown in Figure 38 B arrow ao1, then can adopt the design shown in Figure 38 C, this moment, guide wire 11 same travelings were in the d3 part.If by pushing guide wire 11 or rollback ablation catheter 1 controllable bending tune 5 is bent, namely increase the stress of guide wire 11, the bending direction of the controllable bending tune 5 that the direction that then bends in same design will cause with the tension force of increase guide wire 11 is opposite.If need controllable bending tune 5 to both sides all than being easier to bending, can adopt the design shown in Figure 38 D, namely preferably respectively Figure 32 is set or/and chicken ribs spline structure illustrated in Figure 34 in controllable bending tune 5 relative both sides; When adopting chicken ribs spline structure illustrated in Figure 32, shown in the similar Figure 32 C of its design, just the size in each zone slightly has adjustment (shown in Figure 38 D middle graph), two guide wire 11 preferred respectively travelings are in white space b1 and the b2 shown in Figure 38 D intermediate cross-section figure, because the hardness of bendable control tune 5 both sides is smaller, therefore the tension force that increases certain side guide wire 11 will make controllable bending tune 5 to this lateral bend, and the stress that increases certain side guide wire 11 will make controllable bending tune 5 to lateral bend; When adopting chicken ribs spline structure shown in Figure 34, the blank parts of controllable bending tune 5 is interpreted as the structural rigidity decline that controllable bending tune 5 tube walls keep at a certain distance away among Figure 38 D, such as by removing metal gauze, changing the density of metal gauze etc., guide wire 11 preferred travelings are in the curved side of controllable bending tune 5.Shown in two width of cloth side views about Figure 38 D, the not necessarily full symmetric of arranging of both sides chicken ribs spline structure can have certain dislocation.Can adopt the design shown in Figure 38 D for the controllable bending tune 5 in the design of traction fiber illustrated in Figure 29 10 performance guide wires 11 effects, if when adopting chicken ribs spline structure illustrated in Figure 32, two traction fiber 10 preferred respectively travelings are in white space b1 and b2, if when adopting chicken ribs spline structure shown in Figure 34, two traction fiber 10 preferred travelings are in the curved side of controllable bending tune 5.Realize that for needs multidirectional control crooked (more than or equal to 3 directions) can empty bending section 5 can adopt the design of biconvex disk overlay structure illustrated in Figure 33, guide wire 11 is that b1 sample white space (b1, b2, b3, b4) is passed through in traveling, can increase as required the quantity of b1 sample white space, certainly can also can adopt the expansion design of chicken ribs spline structure illustrated in Figure 32 and the chicken ribs spline structure shown in Figure 34 D to help realize the control multi-direction bending by empty bending section 5.When controllable bending tune 5 is S shape curved design, similar to C shape curved design, the structure of the quantity design controllable bending tune 5 of preferred as required bending direction, Figure 39 describes with the example that is bent into that guide wire 11 is controlled 5 one directions of controllable bending tune by the mode that increases tension force, the structure optimization of controllable bending tune 5 adopts the chicken ribs spline structure at this moment, and the blank parts on the controllable bending tune 5 represents the less part of hardness on the controllable bending tune 5.Wherein Figure 39 A, Figure 39 B and Figure 39 C represent is implementation on the chicken ribs spline structure controllable bending tune 5 that the solid line part is illustrated in Figure 26, and Figure 39 D, Figure 39 E and Figure 39 F then represent is implementation on the chicken ribs spline structure controllable bending tune 5 that dotted portion is illustrated in Figure 26.Shown in Figure 39 A, for figure on the basis that C shape curved design guide wire 11 is arranged, can add in addition a guide wire 11' at the far-end that needs form second bending of S shape bending and be fixed in this, the blank parts of the head end fixing point 111' of guide wire 11' to the controllable bending tune 5 of head end fixing point 111 and the opposite direction of the blank parts of head end fixing point 111' to the controllable bending tune 5 of catheter body section 4, guide wire 11 and guide wire 11' respectively traveling in the relative both sides of controllable bending tune 5, and through the white space of side separately, the tension force that increases simultaneously guide wire 11 and guide wire 11' can realize that S shape shown in Figure 39 A is crooked.Shown in Figure 39 B and Figure 39 C, also can not increase along the quantity of controllable bending tune 5 guide wires 11 and realize that S shape is crooked; Shown in Figure 39 B, respectively melt 9 contact with blood vessel wall is stable after, make controllable bending tune 5 form C shape by guide wire 11 crooked, several stable fulcrum shapes that contact with blood vessel wall are so just arranged, then push ablation catheter 1, because the existence of the blank parts of close second knee similar to Figure 39 A, this part will bend in the propelling movement process, form second bending; Shown in Figure 39 C, also can allow guide wire 11 pass through the blank parts of first sweep in the part of first bending, then turn to again the blank parts by second sweep to the place of second bending, when increasing the tension force of guide wire 11, equally also can form like this S shape crooked.Similarly, Figure 39 D, Figure 39 E and Figure 39 F also adopt Figure 39 A, Figure 39 B and design corresponding to Figure 39 C, just since among Figure 26 first bending curvature of the controllable bending tune 5 of dotted portion less, so the distribution of blank parts is more sparse, size is also smaller.The technical staff can adjust the size, form, branch's density etc. of blank parts on the controllable bending tune 5 to change its bending shape according to practical situation.Can in controllable bending tune 5, implant in addition the hinge arrangement that Figure 35 B, Figure 35 C illustrate or implant joint spline structure that Figure 35 D illustrates so that controllable bending tune 5 is easier bends to some direction.
Figure 40, Figure 41, Figure 42, Figure 43, Figure 44, Figure 45 are take two absolute construction 8 as example, shown the characteristics of line traffic control structure when absolute construction 8 is separated from each other in this utility model and how by adjust absolute construction 8 hardness distribute design deformation more easily realized.The design of controllable bending tune 5 can be continued to use absolute construction 8 far-ends and be connected in design when melting paragraph header end 17, and as shown in figure 40, controllable bending tune 5 is preferred to adopt the crooked and S shape curved design of C shapes.The meaning that blank parts among Figure 41, Figure 42, Figure 43, Figure 44 on the absolute construction 8 represents is interpreted as the structural rigidity reduction that absolute construction 8 keeps at a certain distance away, this lower hardness not only can realize by the mode of change structure design can realizing by the mode that changes material hardness equally, and the hardness distribution of the changes absolute construction 8 such as size that therefore can be by adjusting blank parts, form, distribution density makes it more flexiblely become needed form.Shown in Figure 41 A, when traction fiber 10 travelings when absolute construction 8 is outer, traction fiber 10 preferred major axis centrage travelings by the section of melting 6, this moment, each absolute construction 8 preferably needed a traction fiber 10, the head end fixing point 110 of traction fiber 10 preferably be arranged on melt 9 or contiguous absolute construction 8 on, head end fixing point 110 is by the major axis centrage of the section of melting 6, general apart from melting 9 at 0--8mm, do not melt an absolute construction 8 of 9 for having to arrange, the head end fixing point 110 of traction fiber 10 preferably is arranged on absolute construction 8 head ends or its contiguous absolute construction 8, head end fixing point 110 is by the major axis centrage of the section of melting 6, generally apart from absolute construction 8 head ends at 0--8mm; As shown in figure 40, these traction fibers 10 preferably are merged into one in 1 section of the ablation catheter except the section of melting 6, and preferably traveling in the major axis centrage of 1 section of these ablation catheter.Shown in Figure 41 B, Figure 41 C, when traction fiber 10 travelings when absolute construction 8 is interior, the head end fixing point 110 of traction fiber 10 is preferably different according to the difference in the traveling path of traction fiber 10; Shown in Figure 41 B, when traction fiber 10 by the absolute construction 8 interior traveling of the section of melting 6 major axis centrages the time, head end fixing point 110 preferably be arranged on melt 9 or contiguous absolute construction 8 on, head end fixing point 110 is by the major axis centrage of the section of melting 6, general apart from melting 9 at 0--8mm, for the absolute construction 8 that the energy contact is not set, head end fixing point 110 preferably is arranged on absolute construction 8 head ends or its contiguous absolute construction 8, head end fixing point 110 is by the major axis centrage of the section of melting 6, generally apart from absolute construction 8 head ends at 0--8mm; Shown in Figure 41 C, when traction fiber 10 away from the absolute construction 8 interior traveling of the major axis centrage of the section of melting 6 time, head end fixing point 110 preferably be arranged on melt 9 or contiguous absolute construction 8 on, head end fixing point 110 is away from the major axis centrage of the section of melting 6, general apart from melting 9 at 0--8mm, for the absolute construction 8 that the energy contact is not set, head end fixing point 110 preferably is arranged on absolute construction 8 head ends or its contiguous absolute construction 8, head end fixing point 110 is away from the major axis centrage of the section of melting 6, generally apart from absolute construction 8 head ends at 0--8mm; As shown in figure 40, these traction fibers 10 preferably are merged into one in 1 section of the ablation catheter except the section of melting 6, and preferably traveling in the major axis centrage of 1 section of these ablation catheter.Situation about being separated from each other for absolute construction 8, for convenient control, prefabricated deformation preferably is not set, namely the initial deformation of absolute construction 8 is not made mutually away from state, this moment Figure 41 A, Figure 41 B will mainly rely on the stress (namely pushing traction fiber 10 or the part of rollback ablation catheter 1 except traction fiber 10) that increases traction fiber 10 to realize that absolute construction 8 mutually melts 9 and contacts with blood vessel wall away from finally making, and tension force (being tractive traction fiber 10 or the front part of ablation catheter 1 except traction fiber 10 of sending) the realization absolute construction 8 that Figure 41 C will mainly rely on increase traction fiber 10 mutually melts 9 and contacts with blood vessel wall away from finally making; If certainly the initial deformation of absolute construction 8 is made mutually away from state, Figure 41 A, Figure 41 B will mainly rely on the tension force that increases traction fiber 10 to realize that absolute construction 8 far-ends draw close mutually so that melt 9 and separate with blood vessel wall, if for make melt 9 contact with blood vessel wall tightr, also can increase the stress of traction fiber 10, and Figure 41 C will mainly rely on the stress that increases traction fiber 10 to realize that absolute construction 8 far-ends draw close mutually so that melt 9 and separate with blood vessel wall, if to melt 9 and contact closelyr with blood vessel wall in order to make, also can increase the tension force of traction fiber 10; The structural design that absolute construction 8 amplifies among Figure 41, Figure 42, Figure 43, Figure 44 and corresponding line traffic control structure all do not arrange prefabricated shape with absolute construction 8 and become the basis, can adopt the structural design of absolute construction 8 among Figure 41, Figure 42, Figure 43, Figure 44 when prefabricated deformation is arranged for the absolute construction 8 that does not adopt the line traffic control structure yet.Figure 41 D, Figure 41 E, Figure 41 F represent the structural design that absolute construction 8 amplifies, respectively corresponding diagram 41A, Figure 41 B, Figure 41 C.Shown in Figure 41 D, Figure 41 E, Figure 41 F, contact with blood vessel wall for absolute construction 8 more easily being bent and then conveniently melting 9, be connected in to aforementioned absolute construction 8 that to melt paragraph header end 17 similar, preferably adopt the chicken ribs spline structure, adopt shown in Figure 32 or/and chicken ribs sample design shown in Figure 34 all can; Wherein on the absolute construction 8 shown in Figure 41 D, Figure 41 E, blank parts is arranged in absolute construction 8 by the part of the section of melting 6 centrages, and head end fixing point 110 is to the part of absolute construction 8 near-ends on the absolute construction 8 shown in Figure 41 F, and blank parts will be arranged in absolute construction 8 away from the part of the section of melting 6 centrages; Head end fixing point 110 is to the part of absolute construction 8 far-ends in the absolute construction 8 shown in Figure 41 D, Figure 41 E, Figure 41 F, and the main purpose of blank parts is to melt 9 pressure that contact with blood vessel wall, the protection blood vessel wall by this part being easy to bending to cushion.Figure 42, Figure 43, Figure 44 are that how explanation realizes that ablation points is on different renal artery cross sections as an example of two absolute construction 8 example, the traveling of the setting of this three width of cloth figure empty part, the setting of head end fixing point 110, traction fiber 10 and the Asia figure basic corresponding similar (for example Figure 42 A corresponding diagram 41A) of Figure 41, but realize that the mode of ablation points on different renal artery cross sections is slightly different.As shown in figure 42, this moment two absolute construction 8a, 8b length be equate, internal structure is mirror symmetry substantially, just melt a fixed position of 9 different, the far-end that melts the more close absolute construction 8 of a 9a on the absolute construction 8a can realize that in this way ablation points is on different renal artery cross sections.Such as Figure 43, shown in Figure 44, also can adopt not isometric two absolute construction 8a, 8b, melt 9 heads that all are arranged on each absolute construction 8 owing to the length of two absolute construction 8 is different, therefore can realize that also ablation points is on different renal artery cross sections; The difference of Figure 43 and Figure 44 mainly is the equal in length of traction fiber shown in Figure 43 10, and being uneven in length of traction fiber 10 shown in Figure 44.Figure 41, Figure 42, Figure 43, Figure 44 carry out the design explanation as an example of two absolute construction 8 example, therefore be not limited to the situation of two absolute construction 8, and be applicable too for the situation more than two absolute construction 8.Figure 45 is take two isometric absolute construction 8 as example, illustrates how by hinge arrangement 15 deformation of design more easily to be realized.As shown in figure 45, hinge arrangement 15 preferably is arranged at the near-end of absolute construction 8, the hinge arrangement 15 preferred design forms that adopt the hinge arrangement shown in Figure 35 B; The situation that does not have prefabricated deformation for absolute construction 8, Figure 45 A, Figure 45 B mainly realize that illustrated deformation makes and melt 9 and contact with blood vessel wall by increasing traction fiber 10 stress, and Figure 45 C mainly realizes by increase traction fiber 10 tension force that illustrated deformation makes and melts 9 and contact with blood vessel wall; Be prefabricated into the situation of deformation shown in Figure 45 for absolute construction 8, Figure 45 A, Figure 45 B mainly realize weakening by the tension force that increases traction fiber 10 and melt 9 and contact with blood vessel wall, as the tension force that increases traction fiber 10 then strengthens and melts 9 and contact with blood vessel wall, and Figure 45 C mainly realizes weakening by the stress that increases traction fiber 10 and melts 9 and contact with blood vessel wall, then strengthens such as the tension force of increase traction fiber 10 and melts 9 and contact with blood vessel wall.Hinge arrangement 15 also can replace with the joint spline structure that Figure 35 D illustrates among Figure 45.Figure 45 carries out the design explanation as an example of two isometric absolute construction 8 example, therefore be not limited to the situation of two absolute construction 8, and is applicable too for the not isometric situation more than two absolute construction 8 and absolute construction 8.The situation that needs absolute construction 8 to form other bending shapes for the technical staff in addition maybe needs to change the situation of 10 pairs of absolute construction 8 control forms of traction fiber, can the blank parts of absolute construction 8 among Figure 41, Figure 42, Figure 43, Figure 44 be adjusted accordingly, perhaps the setting position of hinge arrangement illustrated in Figure 45 15 is adjusted.
Figure 46, Figure 47, Figure 48, Figure 49 be take two absolute construction 8 as example, shown in this utility model somewheres in the middle of the absolute construction 8 link together the characteristics of far-end line traffic control structure when being separated from each other again and how by adjust absolute construction 8 hardness distribute design deformation more easily realized.The design of controllable bending tune 5 can be continued to use absolute construction 8 far-ends and be connected in design when melting paragraph header end 17, as shown in figure 46, and controllable bending tune 5 preferred C shape and the S shape designs of adopting.The meaning that blank parts among the blank parts of Figure 47 middle section figure and Figure 48 on the absolute construction 8 represents is interpreted as the structural rigidity reduction that absolute construction 8 keeps at a certain distance away, this lower hardness not only can realize by the mode of change structure design can realizing by the mode that changes material hardness equally, and the hardness distribution of the changes absolute construction 8 such as size that therefore can be by adjusting blank parts, form, distribution density makes it more flexiblely become needed form.As shown in figure 47, when traction fiber 10 travelings outside absolute construction 8 and absolute construction 8 when being two, the junction point 18 of two absolute construction 8 can be made and connect the joint, connecting the joint can link together semi-cylindrical absolute construction 8a, 8b by breechblock e, and can relatively rotate, traction fiber 10 head ends preferably are fixed in this breechblock e, and the major axis centrage traveling of the edge section of melting 6, can only need a traction fiber 10 this moment, this traction fiber 10 in the ablation catheter section 1 except the section of melting 6 preferably traveling in the major axis centrage of 1 section of these ablation catheter;

For bending shape shown in Figure 47 is more easily formed, equally also can adopt the chicken ribs spline structure, outer absolute construction 8b is because curved openings is downward, the downside that therefore can keep at a certain distance away at absolute construction 8b arranges the part that hardness weakens, similarly, inner absolute construction 8b is because curved openings makes progress, and the upside that therefore can keep at a certain distance away at absolute construction 8a arranges the part that hardness weakens; If adopt chicken ribs spline structure illustrated in Figure 32, the cross section enlarged drawing of dotted line cc1, cc2 cross section is the semicircle little figure of upper and lower two width of cloth among Figure 47 among Figure 47, and then the horizontal figure in cross section of the included zone of d6 absolute construction 8a, 8b in Figure 47 namely is respectively the semicircle little figure of upper and lower two width of cloth among Figure 47 among Figure 32 A;

Also can adopt in addition the design of hinge arrangement 15 to promote the section of melting 6 to form the deformation that needs.Figure 50 has realized ablation points on the varying cross-section of tremulous pulse in the not isometric mode of part absolute construction 8, can certainly melt 9 by isometric absolute construction 8 and realize on the varying cross-section of ablation points at tremulous pulse in the different mode of the setting position of each absolute construction 8.Figure 50 carries out the design explanation as an example of four absolute construction 8 example, therefore be not limited to the situation of four absolute construction 8, and is applicable too for the situation more than four absolute construction 8.The situation that needs absolute construction 8 to form other bending shapes for the technical staff in addition maybe needs to change the situation of 10 pairs of absolute construction 8 control forms of traction fiber, can the hardness branch of absolute construction 8 be adjusted, perhaps the setting position of hinge arrangement 15 is adjusted.
Figure 22 E is take four absolute construction 8 as example, shown the characteristics of line traffic control structure when the far-end of all not isometric absolute construction 8 in this utility model is connected in the different parts of traction fiber 10.The outer traction fiber 10 of an absolute construction 8 preferably only is set this moment, and these traction fiber 10 travelings are in the major axis centrage traveling of the section of melting 6, in the ablation catheter section except the section of melting 6 this traction fiber 10 also best traveling in the major axis centrage.The design of controllable bending tune 5 can be continued to use absolute construction 8 far-ends and be connected in design when melting paragraph header end 17, preferably adopts C shape and S shape design.Same, also can promote the section of melting 6 to form the deformation that needs by mode and the hinge arrangement 15 that changes hardness branch.Figure 22 E carries out the design explanation as an example of four absolute construction 8 example, therefore be not limited to the situation of four absolute construction 8, and is applicable too for the situation more than four absolute construction 8.Need absolute construction 8 to form the situation of other bending shapes for the technical staff in addition, can the hardness branch of absolute construction 8 be adjusted, perhaps the setting position of hinge arrangement 15 is adjusted.
Magnetron configuration design for ablation catheter 1, preferably controllable bending tune 5 is adopted the magnetron configuration design, and absolute construction 8 is still adopted the line traffic control structural design, this moment ablation catheter 1, joystick 2, guiding catheter 7 etc. be in that the part of not bringing into play the magnetic attraction guide effect under the externally-applied magnetic field preferably uses can not be by the material of attraction or by the weak material of attraction.When adopting C shape curved design for controllable bending tune 5, preferably permanent magnet, electric magnet or other can be arranged on the cross section of head end fixing point 111 of guide wire 11 by the material of attraction, get final product the bending of more than 5 direction of real controllable bending tune by the change of externally-applied magnetic field direction, namely control the bending direction of controllable bending tune 5; When adopting S shape curved design for controllable bending tune 5, preferably with permanent magnet, electric magnet or other can be arranged on the cross section of head end fixing point 111 of guide wire 11 by the material of attraction, electric magnet is arranged on the fixing cross section of the head end of guide wire 11', for the convenient control magnetic line of force opposite direction on two cross sections preferably, like this under externally-applied magnetic field, controllable bending tune 5 will bend to two different directions, namely form S shape crooked, and owing to therefore can also control by whether switching on for electric magnet on the fixing cross section of the head end of guide wire 11' and form that C shape is crooked or S shape is crooked, can certainly adopt the design of line traffic control structural design and magnetron configuration to control respectively two bendings of S shape curved design;

Since be electric magnet on the absolute construction 8, therefore can be by magnetic line of force direction and the magnetic field intensity of Current Control electric magnet, and this is just so that absolute construction 8 more easily forms the deformation form of design.Also can only adopt the magnetron configuration design to absolute construction 8, preferred absolute construction 8 is two, and controllable bending tune 5 only has prefabricated deformation or/and only the compliance bending can occur, and this moment, the section of melting 6 of absolute construction 8 compositions preferably also can be brought into play guide effect; For the situation that all adopts electric magnet on two absolute construction 8, electric magnet on the absolute construction 8 preferably is arranged on and melts on the cross section of 9 absolute construction 8 of fixing, melt an absolute construction 8 of 9 for not arranging, electric magnet preferably is arranged on needs near the local and position that at first contacts with blood vessel wall after absolute construction 8 deformation, for the situation that far-end is separated from each other again that links together of somewheres in the middle of two absolute construction 8, electric magnet preferably is arranged near four local and positions that needs at first contact with blood vessel wall after absolute construction 8 deformation, variation by electric magnet magnetic induction line direction will so that two absolute construction 8 can form crooked in the same way that guide effect needs, can form again the deformation form that needs when melting; Other can be adopted by the material of attraction (for example metallic iron) situation of electric magnet on another absolute construction 8 except electric magnet for adopting on the absolute construction 8, the electric magnet that all adopts the lower absolute construction 8 of situation of electric magnet on two absolute construction 8 used other can be replaced by the material of attraction except electric magnet, variation by electric magnet magnetic induction line direction on the absolute construction 8 will so that two absolute construction 8 can form crooked in the same way that guide effect needs, can form again the deformation form that needs when melting.Certainly the technical staff can be according to actual needs, adjusts permanent magnet, electric magnet or other can by the setting position of the material of attraction on ablation catheter 1, make ablation catheter 1 form the deformation of other shapes.
In order to help ablation catheter 1 to arrive predetermined ablation locations, guiding catheter 7 can be set in addition.The Main Function of guiding catheter 7 is to be enclosed within ablation catheter 1 outer playing to guide ablation catheter 1 direction and hold ablation catheter 1, so the diameter of guiding catheter 7 is because of bigger than ablation catheter 1.Guiding catheter 7 itself unidirectional or multidirectional ACTIVE CONTROL deformation can occur also or/and Passive Control deformation, and prefabricated deformation (aftermentioned) can be set.
Described ablation catheter 1 and guiding catheter 7 outer surfaces can labelling development scales, with the degree of depth of indication ablation catheter 1 and guiding catheter 7 intravasations and the convenient length of indirectly measuring organization of human body under the image documentation equipments such as ultrasonic, X ray, width etc.Different developing marks also can be set on ablation catheter 1 and the guiding catheter 7 to be used for distinguishing different conduits under the image documentation equipments such as ultrasonic, X ray.Different developing marks preferably is set on each absolute construction 8 to be used for distinguishing different absolute construction 8 under the image documentation equipments such as ultrasonic, X ray, for example at an absolute construction 8 subscript trianglees, and another absolute construction 8 mark squares, or at three bands of an absolute construction 8 subscripts, and two bands of another absolute construction 8 marks.Developing mark also can be set on ablation catheter 1 and the guiding catheter 7 in addition to be used for distinguishing different axial-rotation states under the image documentation equipments such as ultrasonic, X ray, such as the left surface at ablation catheter 1 short-term that can develop is set under the image documentation equipments such as ultrasonic, X ray, at the right flank of ablation catheter the short-term that another can develop is set under the image documentation equipments such as ultrasonic, X ray, two short-terms overlap when ablation catheter 1 is horizontal, when ablation catheter 1 axial-rotation certain angle, short-term then is separated by a distance.In order to reduce the probability of ablation catheter 1 and 7 pairs of blood vessel injuries of guiding catheter, preferably, the place that ablation catheter 1 and guiding catheter 7 contact with blood vessel wall should be as far as possible smooth, simultaneously form should try one's best round and smooth, the head of ablation catheter 1 and guiding catheter 7 is preferably softer in addition.
Figure 51 has shown the primary features of guiding catheter 7 afterbodys in this utility model.Shown in Figure 51 A, according to actual needs, the end of guiding catheter 7 (tail end, near-end) can be provided with side opening 77, after being connected with one section conduit 20, side opening 77 links to each other with syringe or priming device, syringe or priming device can be by injection in the side opening 77 promoting the circulation of blood pipes or injection Intravascular contrast agents, and conduit 20 did not seal when side opening 77 did not use.Shown in Figure 51 A, Figure 51 B, Figure 51 C, the afterbody of guiding catheter 7 preferably has Seal Design, for example sealing ring or sealing shroud 79, anti-Hemostatic Oral Liquid spills and spills to the medicine of intravascular injection or the contrast agent of injection through guiding catheter 7 through guiding catheter 7, what wherein Figure 51 A, Figure 51 B showed is the situation of not inserting ablation catheter 1, what Figure 51 C showed is the situation of inserting ablation catheter 1, and Figure 51 B, Figure 51 C are the enlarged drawing of guiding catheter 7 afterbodys; Rigidized cover 78 is preferably arranged around the afterbody of guiding catheter 7 in addition, make guiding catheter 7 afterbodys be difficult for deformation, convenient operation also conveniently simultaneously is connected with other structures or is attached on other structures.Guiding catheter 7 itself unidirectional or multidirectional ACTIVE CONTROL deformation can occur also or/and Passive Control deformation also can arrange prefabricated deformation simultaneously.Shown in Figure 51 A, the situation of prefabricated deformation is only arranged for guiding catheter 7, guiding catheter control handle 27 (aftermentioned) preferably is not set, its end only arranges jointing 76, and jointing 76 can be connected with syringe, priming device, ablation catheter 1 etc.The ACTIVE CONTROL deformation of guiding catheter 7 preferably adds intellectual material (such as marmem) by the tube wall at guiding catheter 7 and realizes, for example: the marmem design distribution scheme that adopts Figure 27 D to illustrate.The Passive Control deformation of guiding catheter 7 preferably realizes by line traffic control structural design and magnetron configuration design; Wherein the line traffic control structural design namely was to penetrate guide wire 70 (being similar to the guide wire 11 of ablation catheter 1) to realize in guiding catheter 7 tube walls; In order to make things convenient for guiding catheter 7 to form the deformation form of design, the hardness that can also change guiding catheter 7 distributes in addition.Figure 52 has shown the main structure of guiding catheter 7 line traffic control structural designs in this utility model and how has distributed by the hardness of adjusting guiding catheter 7 and promotes guiding catheter 7 to form required deformation form.Shown in Figure 52 A, in a side pipe wall of guiding catheter 7, be provided with guide wire 70, when increasing the tension force of guide wire 70 (tractive guide wire 70 or front guiding catheter 7 other parts except guide wire 70 of sending), guiding catheter 7 will bend to the side that guide wire 70 is set, also i.e. direction shown in the arrow ao1 among the figure is if need multidirectional control bending on several directions of guiding catheter 7 guide wire 70 to be set respectively.In order to make things convenient for guiding catheter 7 to form the deformation form that needs, the hardness that can change guiding catheter 7 segments distributes, and the change that this hardness distributes not only can realize by the mode of change structure design also can realizing by the mode that changes material hardness;

Figure 54 C, Figure 54 D are take the line traffic control structure as example, have illustrated joystick 2 can control the main structure of controllable bending tune 5 joystick 2 in the crooked situation of four direction, and wherein Figure 54 D is the sectional view that Figure 54 C dotted line cc2 cross section amplifies; The design of the joystick 2 that Figure 54 illustrates is mainly improved the previous section of joystick 2, therefore Figure 54 has only illustrated the previous section of joystick 2, the design of the joystick 2 of illustrating for Figure 54 simultaneously and the similar place of the design also no longer repetition here of the joystick 2 that Figure 53 illustrates.Shown in Figure 54 A, control knob 230 is charged into the part of lever 211 and is dwindled to some extent, so that control knob 230 can slide to both direction when being in initial position.Shown in Figure 54 A, each is controlled two guide wire 11a, 11b of the bending of 5 one directions of controllable bending tune and will be respectively links to each other with guide wire fixed disk 204a, 204b on the control knob 230 through interface channel 217a, 217b, similarly also buffer structure can be set, the tractive that spring 208 is used for 230 pairs of guide wires 11 of dash-control button for example is set; When control knob 230 slides to direction shown in the arrow ao1, guide wire 11a will be subject to tractive, and spring 208a stretches, and because the funnel-like groove 218b that interface channel 217b far-end preferably arranges, guide wire 11b is in relaxation state; When control knob 230 slides to direction shown in the arrow ao2, guide wire 11b will be subject to tractive, and spring 208b stretches, and because the funnel-like groove 218a that interface channel 217a far-end preferably arranges, guide wire 11a is in relaxation state.Similarly, in order to realize the rotation by the rotation control operation handle 211 of control knob 230, shown in Figure 54 B, the groove tooth slide construction that preferably adopts dotted rectangle rc to illustrate.Similarly, be handled easily, on the lever 211 or/and signable control knob 230 displacements and moving direction on the control knob 230, on the lever 211, on the lever 247 or/and signable lever 211 and lever 247 relative rotation angle and direction of rotation on the control knob 230.Shown in Figure 54 C, the control knob 230 of control guide wire 11 is replaced by console panel 231 among Figure 54, Figure 54 A, Figure 54 B, console panel 231 is not charged into the part of lever 211, and the contact surface between lever 211 and the console panel 231 is the part in spherical universal joint, therefore console panel 231 can rotate to a plurality of directions, and promotes forward or backward console panel 231 can not move it and skid off lever 211.Figure 54 D is the schematic cross-section that dotted line cc2 cross section amplifies among Figure 54 C, because the cause chart 54C in cross section has only shown two guide wire 11a, 11c.Shown in Figure 54 C, Figure 54 D, each four guide wire 11a, 11b, 11c, 11d that controls the bending of 5 one directions of controllable bending tune will pass through respectively interface channel 217a, 217b, 217c, 217d and link to each other with guide wire fixed disk 204a, 204b, 204c, 204d on the console panel 231 respectively, four guide wires 11 preferably are uniformly distributed on the circumference of console panel 231 and lever 211, similarly also buffer structure can be set, the tractive that spring 208 is used for 231 pairs of guide wires 11 of dash-control dish for example is set; When console panel 231 rotates to direction shown in the arrow ao1, guide wire 11a will be subject to tractive, and spring 208a stretches, and because the existence of interface channel 217c far-end funnel-like groove 218b, guide wire 11c is in relaxation state; When console panel 231 rotates to direction shown in the arrow ao2, guide wire 11c will be subject to tractive, and spring 208c stretches, and because the existence of interface channel 217a far-end funnel-like groove 218a, guide wire 11a is in relaxation state; If console panel 231 rotation directions are not on any one guide wire 11, to have two adjacent guide wires 11 to be subject to tractive this moment, controllable bending tune 5 will be crooked to the direction that two guide wires 11 that are subject to tractive are made a concerted effort like this, namely realize multidirectional control bending by such mode.Similarly, be handled easily, on the lever 211 or/and signable console panel 231 rotation distances or radian and rotation direction on the console panel 231, on the lever 211, on the lever 247 or/and signable lever 211 and lever 247 relative rotation angle and direction of rotation on the console panel 231.Figure 54 C, Figure 54 D only carry out the structure explanation as an example of four guide wires 11 example, the design shown in Figure 54 can also be expanded for the situation of guide wire 11 more than or equal to one.Similarly, for making controllable bending tune 5 form the situation of S shape bending by set up guide wire 11' at second knee, guide wire 11' can be linked to each other with the guide wire fixed disk 204 of this guide wire 11 on control knob 230 or console panel 231 by logical 217 roads of the connection of any one guide wire 11, this guide wire 11 of tractive is with while tractive guide wire 11' like this, certainly the tightness of guide wire 11' and guide wire 11 be can also regulate, first tractive guide wire 11 or guide wire 11' so just can be realized; Guide wire 11' also can finally be fixed on control knob 230 or the console panel 231 independently position by interface channel independently in addition.For controlling controllable bending tune 5 or/and the situation of absolute construction 8 deformation by the magnetron configuration design, remove corresponding line traffic control structure in the design of the joystick 2 that Figure 54 illustrates, change control knob 230 and console panel 231 into design for the magnetron configuration of controlling controllable bending tune 5 Passive Control deformation, annular control knob 257 is changed into the Passive Control deformation that designs for the magnetron configuration of controlling absolute construction 8.For passing through ACTIVE CONTROL shape control controllable bending tune 5 or/and the situation of absolute construction 8 deformation, remove corresponding line traffic control structure in the design of the joystick 2 that Figure 54 illustrates, control knob 230 and console panel 231 are changed into for the ACTIVE CONTROL deformation of controlling controllable bending tune 5, annular control knob 257 is changed into for the ACTIVE CONTROL deformation of controlling absolute construction 8.
ACTIVE CONTROL deformation, Passive Control deformation and front sending with the control of rollback for guiding catheter 7 are mainly passed through 27 realizations of guiding catheter control handle.Because the general line traffic control structure that adopts is controlled the deformation of guiding catheter 7, therefore the design of guiding catheter control handle 27 is take the line traffic control structure as the basis, for other control forms of the deformation of guiding catheter 7, only need improve a little guiding catheter control handle 27 on this basis getting final product.The design of guiding catheter control handle 27 be the design of the joystick 2 illustrated take Figure 53, Figure 54 as the basis, the use that can break of preferred guiding catheter control handle 27 and joystick 2, use also can be bonded together.Figure 55 can control the line traffic control structure of guiding catheter 7 in the crooked situation of direction as example take guiding catheter control handle 27, shown the main structure of guiding catheter control handle 27 and how to break with joystick 2 and engage, to be the joystick 2 illustrated take Figure 54 describe as example the joystick 2 of anticipating shown in Figure 55, but represented the design of aforesaid all joysticks 2.Figure 55 B, Figure 55 C are the schematic cross-section that dotted line cc1 among Figure 54 A, cc2 cross section amplify.Shown in Figure 55 A, guiding catheter control handle 27 mainly is comprised of lever 211', lever 242 and control knob 230', wherein the design of the lever 211 illustrated of the design of lever 211' and control knob 230' and Figure 53 A and control knob 230 is similar, and the guide wire 11 of just Figure 53 A being illustrated has changed guide wire 70 into.Shown in Figure 55 A, guide wire fixed disk 279 is arranged on the control knob 230', interface channel 217' on the guide wire 70 process lever 211' links to each other with the guide wire fixed disk 279 on the control knob 230', can buffer structure be set in guide wire 70 similarly, for example one section of guide wire 70 is replaced with spring 278, perhaps connect tension pick-up in guide wire 70; Guide wire 70 will be subject to tractive when control knob 230' slides to direction shown in the arrow ao.For control knob 230' can be rotated with lever 211', the groove tooth slide construction that dotted rectangle rc illustrates among Figure 55 B is set preferably.Shown in Figure 55 A, similarly, lever 211' and lever 242 by a dotted line the groove tooth slide construction shown in the rectangle frame ar1 link to each other, this groove tooth slide construction is mutually coincide by the annular hook formation 212' on the lever 211' and the annular hook formation on the lever 242 241 and forms, so lever 211' and lever 242 can relatively rotate.In order to make guiding catheter control handle 27 and joystick 2 realize engaging, the front end of joystick 2 need to improve; Shown in Figure 55 D, the front end of joystick 2 is provided with down two hook-shaped latch 210a, the 210b of " L " font, and two hook-shaped latch 210a, 210b are preferably in the relative position setting of circumference;

Draw-in groove 243 just in time can pass through hook-shaped latch 210 near the place narrower (shown in Figure 55 C) of lever 242 ends; Draw-in groove 243 is away from the place of lever 242 ends wider (shown in Figure 55 B), and therefore hook-shaped latch 210 has certain activity space at draw-in groove 243 away from the place of lever 242 ends; The internal diameter of lever 211' preferably just reaches ablation catheter 1 to be passed through, and the internal diameter of lever 242 is a bit larger tham the external diameter of ablation catheter 1, but is slightly less than the external diameter of the rigidized cover 48 of ablation catheter 1, so rigidized cover 48 can snap in lever 242.Such as Figure 55 A, Figure 55 B, Figure 55 C, shown in Figure 55 D, when needs guiding catheter control handle 27 and joystick 2 joint, ablation catheter 1 penetrates in the vacant duct in the guiding catheter control handle 27 and then enters in the guiding catheter 7, when the front end of joystick 2 is terminal near guiding catheter control handle 27, hook-shaped latch 210 is aimed at draw-in groove 243, then push forward joystick 2 so that hook-shaped latch 210 touches the end of draw-in groove 243, this moment, the Spin Control handle 2, hook-shaped latch 210 will be locked in draw-in groove 243 away from the wider place of lever 242 ends, add this moment rigidized cover 48 and snapped in lever 242, so the joint that guiding catheter control handle 27 and joystick 2 can be stable; When needs guiding catheter control handle 27 separated with joystick 2, reverse rotation joystick 2 made hook-shaped latch 210 aim at the narrower place of draw-in groove 243, and rollback joystick 2 gets final product.The design of the guiding catheter control handle 27 of illustrating for Figure 55 is changed to guiding catheter control handle 27 design form of joystick 2 front portions that Figure 55, Figure 54 illustrate and guide wire 11 is replaced with the control that guide wire 70 can realize or multi-direction bending two-way to guiding catheter 7.In order to make things convenient for the operation of guiding catheter control handle 27, can be on the control knob 230' or console panel 231' of control guide wire 70, lever 211' indicates displacement and moving direction or rotation distance and the rotation direction of control knob 230' or console panel 231', on control knob 230' or the console panel 231', on the lever 211', lever 242 indicates lever 211' and lever 242 relative rotation angle and direction of rotation; In order to make things convenient for guiding catheter control handle 27 to engage with joystick 2, can indicate respectively pairs of bit line that both engage, para-position sign etc. on the guiding catheter control handle 27 with on the joystick 2.For the situation by 7 deformation of magnetron configuration design control guiding catheter, remove corresponding line traffic control structure in the guiding catheter control handle 27, change control knob 230' or console panel 231' into for the magnetron configuration design of control guiding catheter 7 Passive Control deformation, and set up for the energy exchange joint that energy is provided to guiding catheter 7 and guiding catheter control handle 27 at guiding catheter control handle 27.For the situation by 7 deformation of ACTIVE CONTROL shape control guiding catheter, remove corresponding line traffic control structure in the guiding catheter control handle 27, change control knob 230' or console panel 231' into for control guiding catheter 7 ACTIVE CONTROL deformation, and set up for the energy exchange joint that energy is provided to guiding catheter 7 and guiding catheter control handle 27 at guiding catheter control handle 27.
