Description
Technical field
The present invention relates to a kind of connector, it is connected with power set for deep venous thrombosis is removed device particularly to a kind of
Quick change union joint.
Background technology
In recent years, because dietary structure such as changes at the reason, people deep vein thrombosis of lower extremity sickness rate presents and increases year by year
Trend.Phlebothrombosises accumulation for a long time can cause circulatory disorders and the stasis of blood stagnant, leads to the long-term swelling of lower limb, varicosis, thus quiet
Arteries and veins Ink vessel transfusing forms thrombophlebitis disease.More severe patient, phlebothrombosises come off and transfer to internal organs also can result in fatal simultaneously
Send out disease, for example, phlebothrombosises are transferred to pulmonary and piled up, patient's thromboembolism can be caused dead.The Therapeutic Method of thrombosis has: 1, interior
Section treats, and mainly adopts the Drug therapy such as anticoagulant, thrombolytic.Drug therapy occurs once in a while bleeds or the situation such as bleeding；In addition,
For some urgent or the in the case of of being critically ill, medication effect is too slow.2nd, surgical operation therapy, has thrombosis to pile up on blood vessel
Position opening, via this otch removal of thromboses.Operative treatment wound for patients with deep venous thrombosis is too big；And, by
In Operative thrombectomy can not completely removal of thromboses, the thrombosis of residual possibly into pulmonary, thus causing fatal pulmonary infarction.3、
Interventional therapy, by the way of percutaneous puncture, by one small otch of patient body-surface by special minimally invasive intervention surgical device
Tool introduces vein, directly carries out contact thrombolysis and take bolt under x x ray fluoroscopy x.Compared with conventional surgical operation therapy, intervention is controlled
Treatment trauma is less, is affected less by phlebothrombosises deposition site depth.
Through the literature search discovery to prior art, the Chinese invention patent of Patent No. zl200320121061.0 is " quiet
Arteries and veins takes bolt pipe " (Authorization Notice No. be cn2659350y) disclose a kind of vein Fogarty.This patent by stilet, take bolt pipe and
Sacculus 3 part, advantage does not damage vein valve for can be taken off extremity deep venous thrombosis.In Patent No. zl96245233.5
State's patent of invention " Catheter for removing thrombus from blood vessel " (Authorization Notice No. is cn2268496y) discloses a kind of Catheter for removing thrombus from blood vessel.This patent
It is actually a kind of double channel catheter, wherein one chamber connects sacculus, so that sacculus is expanded for supplying liquid or gas；An other chamber
For blood jet flow.The advantage of this patent is whether can to reach thrombosis position by automatic discrimination catheter head.This two patents are all adopted
Scrape the function of removing thrombus with a sacculus execution.For some outmoded thrombosis it may be difficult to realize disposably striking off, thus need
Conduit to be reinserted, after dilatation balloon again scraping off residual thrombosis it is easy to lead to partly broken little thrombi to remain in blood
Can not thoroughly be taken out in pipe.
The Chinese invention patent " for treating the slidingtype combined catheter of thrombosis " of Patent No. zl200820098250.3
(Authorization Notice No. is cn201192520y) discloses a kind of slidingtype combined catheter for treating thrombosis.This patent is by one
Core pipe and a sleeve pipe are constituted, and core pipe and bushing head connect a sacculus respectively.This patent coming by bushing head sacculus
Return dragging to scrape removing thrombus.The advantage of this patent employs that two sacculus realize blood vessel temporary plugging respectively and thrombosis strike off
Function, thus decrease the remaining probability of broken microthrombus block.
(Authorization Notice No. is the Chinese invention patent " taking bolt device " of Patent No. zl200620164685.4
Cn201042451y) disclose one kind and take bolt device.This patent carries out thrombosis using the umbrella-shaped structure being made up of memory alloy wire and scrapes
Remove, the thrombosis exclusion after being struck off using sleeve pipe is external.This patent carries out thrombosis using tinsel rather than sacculus and strikes off, Ke Yiti
High scraping effect, but tinsel is also possible to scratch blood vessel simultaneously.
In order to ensure the safe and reliable stable of operation process, and realize taking fast and safely dividing of bolt device and power set
From, for the design taking the integration of bolt device above, design a kind of supporting deep venous thrombosis and remove device quick change union joint, satisfaction
While doctor's operation, realization takes the fast and safely connection of bolt device and power set and separates.
Content of the invention
The purpose of the present invention is it is simply that in order to solve the above problems, provide one kind for removing device and moving deep venous thrombosis
The quick change union joint that power apparatus are connected.
In order to achieve the above object, present invention employs technical scheme below: one kind is for removing device by deep venous thrombosis
The quick change union joint being connected with power set, including union joint body, this union joint body include one axially through center
Pipe and an overcoat, are provided with an afterbody locking mechanism for being connected with power set in the afterbody of union joint body；?
The front portion of union joint body is provided with one for removing, with deep venous thrombosis, the anterior locking mechanism that device is connected；In afterbody kayser
One handle switch mechanism for quickly separating afterbody locking mechanism and power set is connected with mechanism.
Described afterbody locking mechanism include being symmetrically connected to central canal both sides two pick up the ears, and are symmetricly set on overcoat
Two barbs of both sides, form two breach between two barbs, pick up the ears and the orthogonal setting of two barbs for two.
Described front portion locking mechanism includes arranging the axial rectangle slotted eye of four radial direction insertions on the coat, this four
