Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of whole course visible takes thrombus device, is suitable in patient
When lopsided stroke onset, mechanically removal of thromboses that can be more accurate is to realize that intracranial vessel leads to again.
Background technique
The Etiological of cerebral apoplexy is that blocking causes encephalic to distal vessels after the small embolus on cerebral vessels wall falls off
A little blood vessel blood supply insufficiencies entirely shut and lose blood supply ability.According to statistics, China is annual to occur cerebral apoplexy patient up to 3,000,000,
Annual stroke patient death about 1,200,000, the patient of the cerebral apoplexy for being sent to hospital in time, conventional therapeutic scheme is that drug is molten
Bolt, but the optimal window time of drug thrombolysis (disease is dealt into the time to obtain medical treatment) is the thrombolysis within 4 hours, and so short
Time window causes the patient only less than 10% that can obtain effective thromboembolism treatment, and more patients can not be in 4 hours time windows
Interior acquisition effectively treatment, and drug thrombolysis is smaller to the effect of larger thrombus, machinery takes bolt to become and controls in order to which one kind is more efficiently
Treatment means, it by therapeutic time window extend to 24 hours even it is longer, bring benefit to more patients.
