Abstract

The invention discloses a balloon suction catheter device for intracranial thrombus removal and relates to the field of medical instruments. The device comprises an outer sleeve, a suction catheter, aballoon, a first developing ring, a second developing ring, a stress diffusion tube and a Y-shaped handle, the outer sleeve and the suction catheter are coaxially arranged, the proximal part of the suction catheter is arranged in the inner cavity of the outer sleeve, and the suction catheter arranged in the inner cavity of the outer sleeve and the outer sleeve form a double-cavity structure; andthe balloon is fixedly arranged at the distal end of the outer sleeve, the first developing ring is fixedly arranged at the distal end of the outer sleeve and is close to the balloon, the second developing ring is fixedly arranged at the distal end of the suction catheter, and the proximal end of the outer sleeve is connected to the distal end of the stress diffusion tube. The device of the invention not only can reduce the escape probability of embolus and reduce the expense and the operation time, but also has the characteristics of simple structure and various functions.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a balloon suction catheter device for intracranial thrombus removal. Background technique [0002] Stroke is 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 are disabled to varying 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. [0003] Intravenous rt-PA thrombolysis is currently the only effective treatment for acute cerebral infarction proven by evidence...
