Description
Technical field
The present invention relates to a kind of device for conducting cardiovascular and cerebrovascular vessel, cleaning blood vessel embolism, belong to technical field of medical appliance structures.
Background technology
Cerebral thrombosis is more common in middle-aged and elderly people, and cerebral thrombosis is the modal type of cerebral infarction.That cerebral arteries trunk or cortical branches atherosclerosis cause Aldosterone, luminal stenosis obturation and thrombosis, brain regional blood flow is caused to reduce or blood supply interruption, brain tissue ischemia anoxia causes the focal neurological symptom of softening downright bad appearance, that in ischemic cerebrovascular, morbidity is anxious, the acute cerebrovascular disease that lethal, disability rate is high.
Because allowing the time compole carrying out endovascular treatment short, very easily cause massive cerebral infarction, old people's body constitution is poor, and case fatality rate and disability rate are very high.Medical intravenous or the Arterial thrombolysis method of adopting treats thrombosis more at present, and wherein, intravenous thrombolysis therapy takes up rate less than 30%, and Arterial thrombolysis treatment takes up rate less than 60%, and postoperative hemorrhage rate is up to more than 10%.
Summary of the invention
The object of the invention is to the weak point solving the existence of above-mentioned prior art, there is provided a kind of reasonable in design, easy and simple to handle, plasticity is strong, thrombosis can be removed clean while dredging vascellum, and there is the device for conducting cardiovascular and cerebrovascular vessel, cleaning blood vessel embolism of vessel support effect.
One of the present invention is used for conducting cardiovascular and cerebrovascular vessel, the device of cleaning blood vessel embolism, its special character is to comprise guiding catheter 1, the outer wall of guiding catheter 1 is provided with can the inflating balloon 2 of inflation/deflation, microtubular 3 is inserted with in guiding catheter 1, it is inner that microtubular 3 part is positioned at guiding catheter 1, it is outside that part is positioned at guiding catheter 1, microtubular 3 is provided with the driving mechanism 4 for driving microtubular 3 to rotate and aspirator 9, the section tubular wall of microtubular 3 is laid with sucker 5, micro-wire 6 is inserted with in microtubular 3, one end of micro-wire 6 is provided with dismountable anti-bolt net 7, the outside of microtubular 3 is provided with the netted intravascular stent 8 for support blood vessels, in cylindricality after intravascular stent 8 launches,
Further, in order to more convenient to use, described driving mechanism 4 is micromotor;
Further again, the diameter of described sucker 5 is 1-2mm
Further again, the aperture of described anti-bolt net 7 is 4mm*4mm;
Further, the outer surface of described intravascular stent 8 is coated with biomembrane.
Of the present invention for conducting cardiovascular and cerebrovascular vessel, the device of cleaning blood vessel embolism, smart structural design, during use, first insert guiding catheter from femoral artery, by micro-wire, guiding catheter 1 is positioned over thrombosis proximal part, then microtubular is placed in guiding catheter by micro-wire, open the inflating balloon on guiding catheter, blood flow capable of blocking after inflating balloon inflation, start driving mechanism, driving mechanism drives microtubular to rotate, rotation limit, microtubular limit is aspirated, arrive thrombosis body distal end, by micro-wire, anti-bolt net is put into thrombosis distal end to open, inflating balloon is exitted simultaneously, open blood flow, rotate with microtubular while aspirate, the thrombosis of thrombus area is all aspirated totally, in aspiration procedure, the thrombosis fragment come off is stopped completely by the anti-bolt net being positioned at distal end, avoid thrombosis at a distance, after operation is satisfied, anti-bolt net is taken out, outer surface is coated with biomembranous intravascular stent and puts into endovascular thrombus area, support blood vessels.
In sum, the present invention has following beneficial effect:
1, thrombus cleaning is totally thorough;
2, suction limit, microtubular 3 limit is rotated, and reduce thrombosis by disturbance, anti-tampon fragment causes distal vessels thromboembolism;
3, anti-bolt net can be tackled the thrombosis fragment come off after opening, and avoids distal end portion blood vessel embolism;
4, increase the protection to damaged vessel walls, be with biomembranous intravascular stent 8 pairs of thrombi blood vessels to play support and protective effect;
5, inflating balloon can of short duration occluding vascular, reduces the movement of thrombosis;
6, easy and simple to handle, efficiency is high, and greatly reduce the lethal disability rate of cerebral thrombosis, take up rate and reach 93.3%, postoperative hemorrhage rate is less than 6%.
