Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, remove device particularly to a kind of local circulation formula thrombosis.
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 gets more and more.Phlebothrombosis deposition can cause circulatory disorders and stasis, thus forms thrombophlebitis disease in vein blood vessel.For chronic iliofemoral vein thrombosis patients, phlebothrombosis can cause the long-term swelling of lower limb, varicosis, and ulceration is not healed.It addition, phlebothrombosis is also possible to after coming off to transfer to other positions of health and internal organs, thus cause serious complication.Such as, the thrombosis in vein is shifted by vein blood vessel and in pulmonary deposition, can cause pulmonary infarction, cause death.The Therapeutic Method of thrombotic disease has: 1, medical treatment, mainly uses the Drug therapy such as anticoagulant, thrombolytic.Drug therapy occasional occurs bleeding or the symptom such as hemorrhage；It addition, to some emergency case, use pharmacotherapy speed the slowest.2, surgical operation therapy, an otch is opened at the position having thrombosis to deposit on blood vessel, via this otch removal of thromboses.Operative treatment is big for patients with deep venous thrombosis difficulty and wound；And, take bolt process and be inherently likely to result in remaining thrombi and enter pulmonary, thus cause fatal pulmonary infarction.3, interventional therapy, can use the mode of percutaneous puncture, by one small otch of patient body-surface, special Wicresoft's interventional operation equipment is introduced 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 affected less by the phlebothrombosis deposition site degree of depth.
Through finding the literature search of prior art, the Chinese utility model patent " vein Fogarty " (Authorization Notice No. is CN2659350Y) of Patent No. ZL200320121061.0 discloses a kind of vein Fogarty.This patent by stilet, take bolt pipe and sacculus 3 part is constituted, advantage does not damage vein valve for can be taken off extremity deep venous thrombosis.The Chinese utility model patent " Catheter for removing thrombus from blood vessel " (Authorization Notice No. is CN2268496Y) of Patent No. 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, is used for supplying liquid or gas makes sacculus expand；Another chamber is used for blood jet flow.Whether the advantage of this patent is for can arrive thrombosis position by automatic discrimination conduit head end.This two patent all uses a sacculus to perform to scrape the function of removing thrombus.For some old thrombosis, it may be difficult to realize disposably striking off, thus need to reinsert conduit, scraping off residual thrombosis again after dilatation balloon, it is easy to cause the broken little thrombi of part to remain in Ink vessel transfusing and can not thoroughly be taken out.
The Chinese utility model patent " for treating the slidingtype combined catheter of thrombosis " (Authorization Notice No. is CN201192520Y) of Patent No. ZL200820098250.3 discloses a kind of slidingtype combined catheter for treating thrombosis.This patent is made up of a core pipe and a sleeve pipe, and core pipe and sleeve pipe head end link a sacculus respectively.This patent is intended scraping removing thrombus by the dragging back and forth of sleeve pipe head end sacculus.The advantage of this patent is to use two sacculus to realize blood vessel temporary plugging respectively and function that thrombosis strikes off, thus reduces the probability that broken microthrombus block is remaining.
The Chinese invention patent " conduit of fetching intravascular thrombus in human internal organ " (Publication No. CN1072867A) of Application No. 92106702.X discloses the conduit of a kind of fetching intravascular thrombus in human internal organ.This patent with horn mouth by an inner catheter with sacculus and one and is offered the trocar sheath of side opening and constitutes.This patent can during scraping removing thrombus not blocking blood flow.But, the horn mouth of this patent is a fixed-size solid structure, do not adapt to the thickness of different patient vessel, additionally, this solid structure is unfavorable for the sealing of trocar sheath head end and human vas contact site, adding and also have some side openings near horn mouth, these reasons all can not thoroughly be taken out causing the broken little thrombi of part to remain in Ink vessel transfusing.
In above 4 patents, the element that direct execution thrombosis strikes off function is sacculus.Sacculus is originally as flexible member, and smooth surface, adds human vas wall and has certain elasticity, and this makes blood vessel and sacculus during execution thrombosis strikes off that a certain degree of " yielding " all can occur.Some thrombosis, especially old thrombosis is caused not to be struck off up hill and dale.
The Chinese utility model patent " taking bolt device " (Authorization Notice No. is CN201042451Y) of Patent No. ZL200620164685.4 discloses one and takes bolt device.This patent uses the umbrella-shaped structure being made up of memory alloy wire to carry out thrombosis and strikes off, and the thrombosis after using sleeve pipe to strike off excretes.This patent uses tinsel rather than sacculus carries out thrombosis strikes off, and can improve scraping effect.But, tinsel is also possible to scratch blood vessel simultaneously.
Above-mentioned prior art is at following 3 aspect still Shortcomings: 1, removes effect for bolt core or old thrombosis undesirable, removes rate low；2, take bolt process arterial intima, easily form secondary thrombus；3, take fasten during the thrombosis nibs parts that produces remain in that blood is internal enters bypass artery and internal organs, relevant internal organs generation thromboembolism or nonfunction may be caused；4, during taking bolt, normal blood runs off many, is easily caused patient's anemia.
