Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of thrombus with telescopic thrombi disruption elements
Suction catheter.
Background technique
Acute myocardial infarction (AMI) be on the basis of coronary artery pathological changes, occur coronary artery blood supply sharply reduce or in
It is disconnected, make that corresponding cardiac muscle is serious and enduringly acute ischemia leads to myocardial necrosis, AMI morbidity is dangerous, and lethal disability rate is high.Due to
The main reason for atherosclerosis is the pathologic basis for leading to acute cardiocerebrovasculaevents events, leads to acute cardiovascular event is office
The rupture of portion's atherosclerotic plaque and thrombosis, and thrombosis depends on the vulnerability of atherosclerotic plaque, easily
Damage patch is easy to appear plaque rupture and thrombosis, so as to cause the generation of acute coronary syndrome.
Biochemical analyzer is to be applied to a kind of clinical new method in recent years, and the purpose is to be quickly drawn out by mechanism
The thrombus of blockage pathology blood vessel can reduce thrombus load and Microembolization theoretically, change coronary flow, reduce
Medicine is used in combination by thrombus suction catheter in the incidence of postoperative " slow blood flow " and " fluoride-free flux ", clinical also further verifying
Object can obviously reduce the incidence of fluoride-free flux, improve the blood flow of target vessel, improve clinical prognosis, to treatment acute myocardial infarction
Patient has recent and long-term effect well, and after application Biochemical analyzer, has 2/3 case can without carrying out balloon pre-dilation
It is implanted directly into bracket, saves medical expense.
Biochemical analyzer is broadly divided into manual thrombus suction catheter and mechanical Biochemical analyzer device, manual thrombus suction catheter hand
The principle of dynamic suction is to generate negative pressure using syringe suction thrombus is sucked out.Suction unit is by suction catheter, pressure extension tube, pumping
The basic element of character such as suction emitter, aspirate strainer composition, suction catheter generally have lockable connector or threeway.Mechanical thrombus is taken out
Two major classes can be divided into for mechanical Biochemical analyzer device according to working principle by inhaling device: one kind is inhaled by mechanicalness vacuum pump negative pressure
Draw and dispel thrombus (such as Rescue and TVAC), principle is similar with manual thrombus suction catheter, and only its negative pressure suction force is by machinery
Property vacuum pump generate.While persistently forming negative pressure, catheter aspirates thrombi is slowly pushed and withdrawn.Another kind of machinery thrombus
Suction unit is then that thrombus is crushed and excreted by mechanical method, and the mechanism crushed according to thrombus is different can be divided into again
Mechanical rotary-cut and fluid smash two kinds.
For example, the patent application of Patent No. CN102319097A, discloses a kind of thrombus suction catheter, including tube socket
Connecting conduit, mobilizable on the outer wall of the suction tube to be arranged with casing, casing includes Y type connector, double lumen tube and sacculus,
The Y type connector connects double lumen tube, and sacculus is set on the distal end outer wall of double lumen tube；It can be inserted into interference metal in suction tube
Thread, outside the distal end for interfering the extended suction tube in the distal end of wire.The suction catheter can quickly remove that be dispersed in blood vessel extensive
The thrombus in region and the embolism for handling coronary artery tip capilary；When encountering big volume and heavy bodied thrombus, using interference
Wire is aspirated again after breaing up thrombus, allows the present invention that can handle the thrombus inhaled compared with hard-pumped.Although the technical solution solves
The problem of draw volume is big and heavy bodied thrombus, but still have certain deficiency.Firstly, the head end of suction tube is dedolation
Mouthful, although the puncture convenient for suction tube enters, there is also operation error, head end punctures the risk of blood vessel.Secondly, it is broken up
The operation of thrombus can not carry out simultaneously with suction operation, and thrombus can not be carried out in suction breaks up operation, beat carrying out thrombus
It when dissipating, can not be aspirated, need to frequently replace component between two operations, cumbersome, pumping efficiency is lower.
