Description

Thrombectomy support system

Technical Field

The invention relates to the technical field of medical instruments, in particular to a thrombus removal support system.

Background

Cerebral apoplexy (also known as stroke and cerebrovascular accident (CVA)). Is an acute cerebrovascular disease, which is a group of diseases causing brain tissue damage due to sudden rupture of cerebral vessels or failure of blood flow into the brain due to vessel occlusion, including ischemic and hemorrhagic stroke. The incidence rate of ischemic stroke is higher than hemorrhagic stroke, and accounts for 60-70% of the total stroke. Occlusion and stenosis of internal carotid and vertebral arteries can cause ischemic stroke, which is more than 40 years old, more female than male, and death in severe cases. Mortality from hemorrhagic stroke is high. The investigation shows that the urban and rural total stroke becomes the first death reason in China and is also the leading cause of the disability of adults in China, and the stroke has the characteristics of high morbidity, high mortality and high disability rate. Different types of stroke have different treatment modes. Because of the continuing lack of effective therapies, prevention is currently considered to be the best approach, where hypertension is an important controllable risk factor for stroke, and thus treatment with reduced pressure is particularly important in preventing stroke onset and recurrence. The prevention and treatment of apoplexy can be really realized by strengthening the education of the popularization of apoplexy risk factors and premonitory symptoms.

In the patent document No. 201710142837.3, a thrombectomy support system is disclosed, which comprises a thrombectomy support, wherein the distal end of the thrombectomy support is in an open state. Preferably, the thrombectomy support is in a roll shape; the cross section of the thrombus taking support is of an open-loop structure, so that the support has proper supporting force and very good flexibility, and can better reach intracranial bent blood vessels. The thrombus taking support has proper supporting force, is favorable for improving the fusion of the thrombus taking support and the thrombus, does not damage the blood vessel and increases the grasping capacity of the thrombus. Furthermore, due to the special cutting design of the thrombus removal support, the flexibility of the thrombus removal support is guaranteed, meanwhile, the thrombus removal support has good thrombus grabbing capacity, and thrombus can be effectively attached to avoid falling off from the thrombus removal support in the thrombus removal process.

The patent documents can ensure the flexibility of the thrombus taking support and simultaneously have good thrombus grabbing capacity; but the technical solution is lacked for how to provide a thrombus removal stent system with simple structure, stronger adhesiveness and more convenient cutting.
