Abstract

The invention discloses an intracranial vascular thrombus extractor. The intracranial vascular thrombus extractor comprises a thrombus extracting support, developing elements, a conveying catheter, a storage tube and a conveying guide wire. The thrombus extracting support comprises branches, a far end and an integral framework. One ends of the branches are fixedly connected with the thrombus extracting support into a whole, and the other ends of the branches are free ends. The developing elements are arranged on the thrombus extracting support, and the number of the developing elements is at least two. According to the intracranial vascular thrombus extractor, the whole thrombus extracting support can be developed, the branches are arranged on the thrombus extracting support, the developing elements are arranged on the branches, the developing effect is enhanced, a surgeon can rapidly and accurately position the thrombus extracting support in the operation process, the situation that a blood vascular wall is damaged due to the fact that the shaking amplitude of the thrombus extracting support is too large is avoided, and the problems that the support is inaccurate in positioning, the thrombus extracting time is too long, and thrombus falls off are solved.

Description

technical field [0001] The invention relates to the field of medical device research, in particular to an intracranial blood vessel thrombus retriever. Background technique [0002] Stroke is currently one of the common diseases in the world, and its characteristics are: high incidence rate, high prevalence rate, and high disability rate. The annual incidence of cerebrovascular disease in my country's urban areas is 219 / 100,000, and that in rural areas is 185 / 100,000, and it is still increasing year by year. From 1998 to 2008, the prevalence of cerebrovascular disease increased from 5.9‰ to 9.7‰. Among the surviving patients with cerebrovascular disease, about three-quarters of them are disabled in different degrees. It is reported that 80% of stroke patients have different degrees of limb dysfunction, and 43.7% of them cannot take care of themselves. Intravenous rt-PA thrombolysis is currently the only effective treatment for acute cerebral infarction proven by evidence-b...
