Description

The power set except device are got for thrombosis

Technical field

The present invention relates to a kind of medical apparatus and instruments, particularly a kind ofly get power set except device for 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 in vein blood vessel, form thrombophlebitis disease.For chronic iliofemoral vein thrombosis patients, phlebothrombosis can cause the long-term swelling of lower limb, and varicosis, ulceration is not healed.In addition, also may transfer to other positions of health and internal organs after phlebothrombosis comes off, 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 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, an otch is opened at position blood vessel having thrombosis deposit, via this otch removal of thromboses.Operative treatment for patients with deep venous thrombosis difficulty and wound large; And, get bolt process and inherently likely cause remaining thrombi to enter pulmonary, thus cause fatal pulmonary infarction.3, interventional therapy, can adopt 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 remove 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 utility model patent " vein Fogarty " (Authorization Notice No. is CN2659350Y) of ZL200320121061.0 discloses a kind of vein Fogarty.This patent by stilet, get bolt pipe and sacculus 3 part is formed, advantage does not damage 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 " (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 links sacculus, for supplying liquid or gas makes inflation; 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 adopts a sacculus to perform 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 remain in Ink vessel transfusing and can not thoroughly be taken out.

The patent No. is that Chinese utility model 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 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 the function that employing two sacculus realize blood vessel temporary plugging and thrombosis respectively and strike off, thus reduces the probability of broken microthrombus block remnants.

The patent No. is enclose utility model patent " getting bolt device " (Authorization Notice No. is CN201042451Y) in ZL200620164685.4 to disclose one and get 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 be excreted 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 simultaneously also likely scratch blood vessel.

Above-mentioned prior art still Shortcomings in following 3: 1, bolt core or old thrombosis are got except effect is undesirable, get except rate is low; 2, get bolt process arterial intima, easily form secondary thrombus; 3, get the thrombosis nibs parts produced in the process of fastening to remain in blood inside and enter bypass artery and internal organs, relevant internal organs generation thromboembolism or nonfunction may be caused; 4, getting normal blood in bolt process runs off many, easily causes patient's anemia.

Summary of the invention

Object of the present invention, exactly in order to solve the problem, there is provided a kind of and get power set except device for thrombosis, this device is and the earlier application of the applicant " local circulation formula thrombosis is got except device " and " for deep venous thrombosis being got the quick change union joint except device is connected with power set " matching used device.

In order to achieve the above object, present invention employs following technical scheme: a kind ofly get power set except device for thrombosis, comprise pedestal and be arranged on fluid infusion pump on pedestal, take out bolt pump, motor and control panel; Described fluid infusion pump front end is connected with and is connected except device for getting with thrombosis and is got by thrombosis except device is to the fluid infusion syringe of human vein liquid make-up, take out bolt pump front end be connected with for thrombosis get to be connected except device and got by thrombosis except device, the thrombosis in human vein is extracted out take out bolt syringe, motor driving shaft front end is provided with for getting with thrombosis the square hole that the transmission square shaft except device is connected, and motor driving shaft outer race has for getting with thrombosis the union joint that the quick change union joint except device is connected.

Described union joint to be arranged on pedestal and to be sleeved on the periphery of motor driving shaft, comprise a conical body, being provided with at the rear portion of conical body for getting with thrombosis the annular steps that the quick change union joint axial location except device is connected, being provided with in the front portion of conical body for getting with thrombosis the cross notch that the quick change union joint radial location except device is connected.

Described control panel is provided with rotating speed, the fluid infusion pump for showing motor and takes out the pressure of bolt pump and the display of flow, and power switch button, operation button and motor speed adjusting knob.

The power set got except device for thrombosis of the present invention coordinate thrombosis to get except device uses, scrape removing thrombus thoroughly, damage tunica intima of vein can be prevented, thrombosis thoroughly can be excreted, avoid residual in human body of broken microthrombus block.The present invention is suitable for that human limb is venothrombotic to be struck off, and is especially applicable to adopting minimal invasion surgical technic to carry out striking off of human body femoral vein depths thrombosis.
