Description
Technical field
The utility model is related to the field of medical instrument technology more particularly to a kind of thrombus remove devices.
Background technology
Thrombus is that blood flow is formed by fritter on the surface of cardiovascular system blood vessel inner face exfoliation or mend.Variable
Fluid dependent form in, thrombus is by insoluble fibrin, the blood platelet of deposition, the leucocyte of accumulation and the red blood cell group being absorbed in
At thrombosis is by one group of h and E factor interaction, interactional multifactor change procedure.It is clinical common
Thrombosis patients, most important feature have a Familial Occurrence, repeated relapsing, symptom severity, thrombosis position abnormality, with
And disease time rejuvenation, it is diagnosis to suspect that artery or venous thronbosis or thromboembolism need objective basis angiographies
Reference standard, but the ultrasound detection operated by consummate skill can also check superficial vein and heart.
Curing thrombus uses thrombolytic drug, antiplatelet drug and anti-coagulants.Heparin is controlled thrombotic disease
It is anticoagulation key agents in treatment, can effectively prevents and treats Lower limb deep venous thrombosis, is widely used in recent years not
Stable angina pectoris, acute myocardial infarction AMI and brain soldier wait indefinitely the treatment of disease.But heparin has shortcomings, such as easy bleeding, it is necessary to
Laboratory clotting mechanism monitoring is carried out, it is inconvenient to use, and decrease of platelet and aleucia can be induced etc..
The thrombus of intravascular generation is taken out, the revascularization of occlusion is made, is the key that recovery thrombus blocking blood vessel, and
The frontier of world blood vessel research at present.But there are many shortcomings for the thrombus remove device of current stage, for example,
Existing thrombus removes equipment and will produce the up to residual of 30%-50%, existing equipment when carrying out thrombus removing and exist
