Description
Technical field
The present invention relates to a kind of connector, particularly a kind of quick change union joint for deep venous thrombosis being got except device is connected with power set.
Background technology
In recent years, due to reasons such as dietary structure changes, people's deep vein thrombosis of lower extremity sickness rate presents the trend increased year by year.Phlebothrombosis accumulation for a long time can cause circulatory disorders and the stasis of blood stagnant, cause the long-term swelling of lower limb, varicosis, thus in vein blood vessel, form thrombophlebitis disease.More severe patient, phlebothrombosis comes off and transfers to internal organs and also may cause fatal complication, and such as, phlebothrombosis is transferred to pulmonary and piled up, and patient's thromboembolism can be caused dead.The Therapeutic Method of thrombosis has: 1, medical treatment, mainly adopts the Drug therapy such as anticoagulant, thrombolytic.Drug therapy occasional occurs bleeding or the situation such as hemorrhage; In addition, or the situation of being critically ill urgent for some, medication effect is too slow.2, surgical operation therapy, blood vessel has the position opening that thrombosis is piled up, via this otch removal of thromboses.Operative treatment is too large for wound patients with deep venous thrombosis; And because Operative thrombectomy can not removal of thromboses completely, residual thrombosis may enter pulmonary, thus causes fatal pulmonary infarction.3, interventional therapy, adopts the mode of percutaneous puncture, and special Wicresoft's interventional operation equipment is introduced vein by the otch small by patient body-surface one, directly carries out contact thrombolysis and get bolt under x-ray fluoroscopy.Compared with the surgical operation therapy of routine, interventional therapy wound is less, and the impact by the phlebothrombosis deposition site degree of depth is less.
Through finding the literature search of prior art, the patent No. is that the Chinese invention patent " vein Fogarty " (Authorization Notice No. is CN2659350Y) of ZL200320121061.0 discloses a kind of vein Fogarty.This patent, by stilet, gets bolt pipe and sacculus 3 part, and advantage does not damage vein valve for taking out extremity deep venous thrombosis.The patent No. is that the Chinese invention patent " Catheter for removing thrombus from blood vessel " (Authorization Notice No. is CN2268496Y) of ZL96245233.5 discloses a kind of Catheter for removing thrombus from blood vessel.This patent is actually a kind of double channel catheter, and wherein a chamber connects sacculus, for supplying liquid or gas makes inflation; An other chamber is used for blood jet flow.Whether the advantage of this patent is for can arrive thrombosis position by automatic discrimination catheter head.These two patents all adopt a sacculus to perform the function of scraping removing thrombus.For some outmoded thrombosis, may be difficult to realize disposable striking off, so just need to reinsert conduit, scraping off residual thrombosis again after dilatation balloon, is easy to cause the broken little thrombi of part remain in Ink vessel transfusing and can not thoroughly be taken out.
The patent No. is that Chinese invention patent " being used for the treatment of the slidingtype combined catheter of thrombosis " (Authorization Notice No. is CN201192520Y) of ZL200820098250.3 discloses a kind of slidingtype combined catheter being used for the treatment of thrombosis.This patent is made up of a core pipe and a sleeve pipe, and core pipe and bushing head are connected a sacculus respectively.This patent scrapes removing thrombus by the dragging back and forth of bushing head sacculus.The advantage of this patent have employed two sacculus to realize the function that blood vessel temporary plugging and thrombosis strike off respectively, thus decrease the probability of broken microthrombus block remnants.
The patent No. is that the Chinese invention patent " getting bolt device " (Authorization Notice No. is CN201042451Y) of ZL200620164685.4 discloses one and gets bolt device.This patent adopts the umbrella-shaped structure be made up of memory alloy wire to carry out thrombosis and strikes off, and adopts sleeve pipe to get rid of external by the thrombosis after striking off.This patent adopts tinsel but not sacculus carries out thrombosis strikes off, and can improve scraping effect, but tinsel also likely scratch blood vessel simultaneously.
In order to ensure the safe and reliable stable of operation process, and realize getting fast and safely being separated of bolt device and power set, for the design of getting the integration of bolt device above, designing a kind of supporting deep venous thrombosis gets except device quick change union joint, while meeting doctor's operation, the fast and safely connection realizing getting bolt device and power set be separated.
Summary of the invention
Object of the present invention, exactly in order to solve the problem, provides a kind of quick change union joint for deep venous thrombosis being got except device is connected with power set.
In order to achieve the above object, present invention employs following technical scheme: a kind of quick change union joint for deep venous thrombosis being got except device is connected with power set, comprise union joint body, this union joint body comprises the through central canal of axis and an overcoat, and the afterbody of union joint body is provided with a trailer card latch mechanism for being connected with power set; One is provided with for getting anterior locking mechanism except device is connected with deep venous thrombosis in the front portion of union joint body; Trailer card latch mechanism is connected with a handle switch mechanism for trailer card latch mechanism and power set being separated fast.
Described trailer card latch mechanism comprises symmetry and is connected to two of central canal both sides and picks up the ears, and is symmetricly set on two barbs of overcoat both sides, forms two breach, pick up the ears and two orthogonal settings of barb for two between two barbs.
Described anterior locking mechanism comprises the through axial rectangle slotted eye of setting four radial directions on the coat, and overcoat is divided into four lock dogs by these four rectangle slotted eyes, and the outside of each lock dog is equipped with barb.
Described handle switch mechanism comprises two symmetrically arranged spanners, two spanners are connected with the end of two barbs of trailer card latch mechanism respectively, the afterbody of spanner is extruded inwards, realizes two barbs and outwards open, thus realize being separated of trailer card latch mechanism and power set.
