Description
Technical field
The utility model is related to the field of medical instrument technology more particularly to a kind of thrombus removers.
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 remover of current stage, for example, existing
Some thrombus remove equipment and will produce the up to residual of 30%-50% when carrying out thrombus removing, and existing equipment is being led
Fragment when pipe enters clot, countless can stay in blood vessel, reduce blood flowing speed, cause tissue necrosis.
Such as application No. is：200720172190.0 Chinese patent disclose a kind of Intravascular Thrombus and embolus excision
Device has thrombectomy device, it is characterised in that：The thrombectomy device includes the mesh basket (3) in contraction or release conditions, mesh basket
(3) it is located at the distal end of thrombectomy device, is coaxially connected with conducting wire pole (6) with mesh basket (3), conducting wire pole (6) is distally connected with softness
Conductive filament head (1)；Entire thrombectomy device can be in delivery conduit (8) when being in contraction state for the mesh basket (3)；The conveying
In recycling conduit (9), delivery conduit (8) can be stretched out along recycling conduit (9) to distal end for conduit (8) setting；It is disclosed in the present application
Thrombectomy device utilizes excision spring pair by the way that the reception device of mesh basket structure is arranged in the blood flow distal end at thrombectomby position
Thrombus is wound excision, is finally recycled in mesh basket structure, and endovascular blood flow is kept to may pass through mesh basket knot during this
Structure is able to continue to flow, but spring device for excising is when cutting off thrombus, unavoidable to will produce some minimum thrombus
Fragment enters across mesh basket reception device intravascular together in company with blood, may again be generated more by long time integration
More thrombus, do harm to huamn body.
