Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Fig. 3 and Fig. 4 is the structural representation of the medical pilot sleeve device in the embodiment of the present invention.
Referring to Fig. 3 and Fig. 4, presently preferred embodiments of the present invention provides one for medical guider, and including eccentric adjusting sleeve 6 and sleeve handle 8, sleeve handle 8 is arranged on the one end of eccentric adjusting sleeve 6, and the outside of eccentric adjusting sleeve 6 is provided with the first locking mechanism.In the present embodiment, eccentric adjusting sleeve 6 includes the first sleeve part 63, the 61, second sleeve part the 62, the 3rd, sleeve part of different-diameter, and sleeve part 63, the 61, second sleeve part 62 the 3rd, the first sleeve part is one-body molded.Sleeve handle 8 includes a pair handle 81, and handle 81 is symmetrically disposed in the both sides of the first sleeve part 61.
The check lock lever 7 of the first preferably a pair of symmetry of locking mechanism, first end of check lock lever 7 is fixed on the outer surface of eccentric adjusting sleeve 6 by the way of welding, second end of check lock lever 7 is connected, so that handle 81 is connected with eccentric adjusting sleeve 6 by the way of welding with handle 81 respectively.It is preferred that the bearing of trend of the bearing of trend of the first end of check lock lever 7 and the second end is perpendicular, check lock lever 7 also has bending part 71, between first end and the second end of check lock lever 7.
Fig. 5 is the structural representation of caster assembly therefor in the embodiment of the present invention for fixation bone fracture plate.Refer to Fig. 5, first locking mechanism in the outside of eccentric adjusting sleeve 6 and the matching of the second locking mechanism on caster assembly therefor in Fig. 55, thus the position of fixed guide sleeve arrangement.In the present embodiment, second locking mechanism is semi-circular recesses 52, semi-circular recesses 52 is symmetrically disposed in the both sides of fixing hole 51 and is connected with fixing hole 51, the bending part 71 of check lock lever 7 is corresponding to the groove 52 on caster assembly therefor 5, after pilot sleeve device 4 inserts caster assembly therefor 5, check lock lever 7 bends the most laterally, it is resisted against on the inner surface of groove 52, produce a power laterally, the inner surface of groove 52 then applies a reciprocal compression stress to check lock lever 7, so that the outer surface that handle 81 is against the first sleeve part 61 plays the effect of an auto lock, pilot sleeve device 4 is made to carry out position and lock after inserting caster assembly therefor 5.
Please also refer to Fig. 3-Fig. 7, Fig. 6 is the generalized section of guider for fixation bone fracture plate in the embodiment of the present invention, and Fig. 7 is the structural representation of lockplate in the embodiment of the present invention；In the present embodiment, 61, second sleeve part, first sleeve part 62 of eccentric adjusting sleeve 6 and the diameter of the 3rd sleeve part 63 are sequentially reduced, and eccentric adjusting sleeve 6 has through hole 64, according to different needs, can be shoulder hole by via design, the such as through-hole diameter at the first sleeve part 61 be more than the through-hole diameter at the second sleeve part 62 and the 3rd sleeve part 63.In this preferred embodiment, 3rd sleeve part 63 is biased relative to the first sleeve part 61 and the second sleeve part 62, namely, the central axis of the 3rd sleeve part 63 and the first sleeve part 61 and the centerline axis parallel of the second sleeve part 62 but the most overlapping, and the first sleeve part 61 and central axis conllinear of the second sleeve part 62.
During use, the combination bore 91 on lockplate 9 is inserted in the end of the 3rd sleeve part 63, and therefore, the outside diameter size of the 3rd sleeve part 63 can mate setting according to the size of the lock hole 92 of the combination bore 91 arranged on lockplate and pressurization hole 93.On the other hand, referring to Fig. 6, the handle 81 that the lateral symmetry of eccentric adjusting sleeve 6 is arranged is with arc groove 83, it is simple to the finger of user carries out pressing operation.
Fig. 8 is that in the embodiment of the present invention, humerus blade plate guides fixing system structure schematic diagram.Referring to Fig. 6 and Fig. 8, the guidance system for fixation bone fracture plate that the present invention provides, including pilot sleeve device 4, caster assembly therefor 5, lockplate 9 and connecting rod 10.Pilot sleeve device 4 sequentially passes through caster assembly therefor 5 and lockplate 9, and fixed with caster assembly therefor 5 by the first latch-up structure and the second latch-up structure, connecting rod 10 is substantially in J-type, its one end is connected with caster assembly therefor 5, the other end is connected with lockplate 9, so that caster assembly therefor 5 position relative with lockplate 9 keeps immobilizing.Fixing hole 51 on caster assembly therefor 5 is corresponding with combination bore 91.
Described first locking mechanism and the second locking mechanism can have multiple coupling structure, it has been observed that the first locking mechanism is preferably check lock lever 7, the second locking mechanism is the groove 52 matched with check lock lever 7.In other embodiments, the first latch-up structure and the second latch-up structure can also use other multiple fit structures, such as: the first locking mechanism is the first protruding (not shown), and the second locking mechanism is the slotted eye matched with described first projection；First locking mechanism is the first groove (not shown), and the second locking mechanism can be the second projection with described first groove match, described first groove or the first projection outside being axially disposed within eccentric adjusting sleeve 6 along eccentric adjusting sleeve 6；And described first locking mechanism and the second locking mechanism are the buckle structure etc. being mutually matched, if the first locking mechanism carry out with the second locking mechanism on caster assembly therefor 5 mating positioning and locking just can, this is no longer going to repeat them.
Refer to Fig. 7 and Fig. 8, the specifically used mode that above-mentioned guidance system is described as a example by fixed system is guided below by proximal humerus blade plate, multiple combination bore 91 it is provided with on lockplate 9, combination bore 91 is combined into figure of eight hole by lock hole 92 and pressurization hole 93, fixing hole 51 on caster assembly therefor 5 is corresponding to the combination bore 91 on proximal humerus lockplate 9, pilot sleeve device 4 loads in the fixing hole 51 of caster assembly therefor 5, can select corresponding to the lock hole 92 on lockplate 9 or pressurization hole 93 by the rotations of 180 degree, the demand of different fixed form is met under Minimally Invasive Surgery environment.
To sum up, the guider that the present invention provides is by arranging eccentric adjusting sleeve, and the locking mechanism arranging on eccentric adjusting sleeve and matching in caster assembly therefor through hole, during use, manually eccentric adjusting sleeve device is loaded in guide hand delthyrium, adjust placement direction, insert eccentric adjusting sleeve device, after unclamping sleeve handle, the locking mechanism of eccentric adjusting sleeve device can play a self-locking and the effect of orientation；One guider is by rotating the location that can realize two positions, therefore, can meet the requirement of locking compress combination bore design in lockplate, while the operation realizing Micro trauma gets involved and can meet the demand of difference fixed form.
Although the present invention discloses as above with preferred embodiment; so it is not limited to the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when making a little amendment and perfect, therefore protection scope of the present invention is when with being as the criterion that claims are defined.
