Thrombus-taking assembly and thrombus-taking device using thrombus-taking assembly and thrombus-taking method

Abstract

The invention relates to a thrombus-taking assembly and a thrombus-taking device using the thrombus-taking assembly and a thrombus-taking method. The thrombus-taking device comprises the thrombus-taking assembly. The thrombus-taking assembly comprises a thrombus-taking stent used for being conveyed to corresponding blood vessels from the back to the front. The thrombus-taking stent is connected with a stent conveying wire and further comprises a net cover used for being arranged on the front side of the thrombus-taking stent. The net cover is connected with a net cover wire. The net cover is provided with a cover opening sleeving the thrombus-taking stent from the front to the bottom.The thrombus-taking assembly and the thrombus-taking device using the thrombus-taking assembly and the thrombus-taking method have following beneficial effects: the problems in the prior art such as the requirement for high flexibility of net cover material, and proneness of damaging blood vessel walls during an overturning process of the net cover are solved.

Description

technical field [0001] The invention relates to a thrombectomy assembly for mechanically removing intracranial thrombus in a medical device, a thrombus retrieval device and a thrombus retrieval method using the thrombus retrieval assembly. Background technique [0002] In my country, acute stroke is the third leading cause of death and the first leading cause of disability. According to statistics, there are about 2 million new cases of stroke in the country every year, about 1.5 million people die of stroke every year, and about 6.5 million stroke survivors. The annual direct cost of stroke in the country exceeds 20 billion yuan. Hemorrhagic stroke accounts for about 85% of all patients. [0003] Once acute ischemic stroke occurs, how to quickly remove the thrombus blocking the blood vessel is the key to the success of the treatment. There are two conventional treatment methods. The first is to eliminate thrombus with thrombolytic drugs; the second is to remove thrombus me...
