Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, and particularly a kind of local circulation formula thrombosis is got except device.
Background technology
Due to reasons such as dietary structure changes, the sickness rate of people's thrombotic disease presents and increases trend, and especially deep vein thrombosis of lower extremity case is more and more.Phlebothrombosis deposition can cause circulatory disorders and stasis, thereby in vein blood vessel, forms thrombophlebitis disease.For chronic iliofemoral vein thrombosis patient, phlebothrombosis can cause the long-term swelling of lower limb, varicosis, and ulceration is not healed etc.In addition, after phlebothrombosis comes off, also may transfer to other positions of health and internal organs, thereby cause serious complication.For example, the XUESHUANTONG in vein is crossed vein blood vessel and is shifted and in pulmonary deposition, can cause pulmonary infarction, causes death.The Therapeutic Method of thrombotic disease has: 1, medical treatment, mainly adopts the Drug therapy such as anticoagulant, thrombolytic.Drug therapy occasional occurs bleeding or the symptom such as hemorrhage; In addition, to some emergency case, adopt pharmacotherapy speed too slow.2, surgical operation therapy has the position of thrombosis deposition to open an otch, via this otch removal of thromboses on blood vessel.Operative treatment is large for patients with deep venous thrombosis difficulty and wound; And, get bolt process itself and just likely cause remaining thrombi to enter pulmonary, thereby cause fatal pulmonary infarction.3, interventional therapy, can adopt the mode of percutaneous puncture, by small otch of patient body-surface, special Wicresoft's interventional operation equipment is introduced to vein, directly carries out contact thrombolysis and except bolt under x-ray fluoroscopy.Compared with conventional surgical operation therapy, interventional therapy wound is less, is subject to the impact of the phlebothrombosis deposition site degree of depth less.
Through the literature search of prior art is found, the Chinese utility model patent " vein Fogarty " (Granted publication number is CN2659350Y) that the patent No. is ZL200320121061.0 discloses a kind of vein Fogarty.This patent by stilet, get bolt pipe and sacculus 3 parts form, advantage is not damaged vein valve for taking out extremity deep venous thrombosis.The patent No. is that the Chinese utility model patent " Catheter for removing thrombus from blood vessel " (Granted publication number 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 links sacculus, for supplying liquid or gas makes inflation; Another chamber is for blood jet flow.Whether the advantage of this patent is for arriving thrombosis position by automatic discrimination conduit head end.This two patent all adopts a sacculus to carry out the function of scraping removing thrombus.For some old 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 to remain in blood vessel and can not be thoroughly taken out.
The patent No. is that the Chinese utility model patent " being used for the treatment of the slidingtype combined catheter of thrombosis " (Granted publication number is CN201192520Y) of ZL200820098250.3 discloses a kind of slidingtype combined catheter that is used for the treatment of thrombosis.This patent is made up of a core pipe and a sleeve pipe, and core pipe and sleeve pipe head end link respectively a sacculus.This patent is intended dragging back and forth to scrape removing thrombus by sleeve pipe head end sacculus.The advantage of this patent is to adopt two sacculus to realize respectively the function that blood vessel temporary plugging and thrombosis strike off, thereby has reduced the probability of broken [Dan piece remnants.
Application number is the conduit that the Chinese utility model patent " conduit of fetching intravascular thrombus in human internal organ " (publication number is CN1072867A) of 92106702.X discloses a kind of fetching intravascular thrombus in human internal organ.This patent is made up of with horn mouth the trocar sheath that offers side opening an inner catheter with sacculus and one.This patent can be in the process of scraping removing thrombus blocking blood flow not.But, the horn mouth of this patent is a fixed-size solid structure, the thickness that can not adapt to different patient vessels is not etc., in addition, this solid structure is unfavorable for the sealing of trocar sheath head end and human vas contact site, near adding horn mouth, also have some side openings, these reasons all will cause the broken little thrombi of part to remain in blood vessel and can not thoroughly be taken out.
In above 4 patents, directly carry out the element that thrombosis strikes off function and be sacculus.Sacculus is originally as flexible member, and smooth surface, adds human vas wall and has certain elasticity, and this makes the process medium vessels and the sacculus that strike off at execution thrombosis that " yielding " all can occur to a certain degree.Cause some thrombosis, especially old thrombosis can not be struck off up hill and dale.
The patent No. is that the Chinese utility model patent " getting bolt device " (Granted publication number for CN201042451Y) of ZL200620164685.4 discloses one and gets bolt device.This patent adopts the umbrella-shaped structure being made up of memory alloy wire to carry out thrombosis and strikes off, and adopts sleeve pipe that the thrombosis after striking off is excreted.This patent adopts tinsel but not sacculus carries out thrombosis strikes off, and can improve and strike off effect.But, simultaneously also scratch blood vessel likely of tinsel.
Above-mentioned prior art Shortcomings still aspect following 3: 1, get except effect for bolt core or old thrombosis undesirable, get except rate low; 2, get bolt process arterial intima, easily form secondary thrombus; 3, get the thrombosis particle part producing in the process of fastening and remain in blood inside and enter bypass tremulous pulse and internal organs, may cause relevant internal organs generation thromboembolism or nonfunction; 4, get in bolt process normal blood and run off manyly, easily cause patient's anemia.
