Device for dredging cardio-cerebral vessels and cleaning vascular thrombosis

Abstract

The invention relates to a device for dredging cardio-cerebral vessels and cleaning vascular thrombosis, and belongs to the technical field of medical appliance structures. The device comprises a guiding catheter, wherein an inflatable balloon which can be inflated and deflated is arranged on the outer wall of the guiding catheter, and a microcatheter is inserted in the guiding catheter; a part of the microcatheter is positioned inside the guiding catheter, and a part of the microcatheter is positioned outside the guiding catheter; a driving mechanism used for driving the microcatheter to rotate and a sucking device are arranged on the microcatheter; sucking holes are distributed in partial wall of the microcatheter; a micro-guiding wire is inserted in the microcatheter; a detachable anti-thrombus ball net is arranged at one end of the micro-guiding wire; and a reticular vessel stent for supporting vessels is arranged outside the micro-catheter, and is of a cylindrical shape after being unfolded. The device is reasonable in structure design, simple and convenient to operate and strong in plasticity, can be used for sucking and cleaning thrombus while dredging vessels, and has a vessel supporting effect.

Description

technical field [0001] The invention relates to a device for guiding cardiovascular and cerebrovascular and clearing blood vessel embolism, which belongs to the technical field of medical device structure. Background technique [0002] Cerebral thrombosis is more common in middle-aged and elderly people, and cerebral thrombosis is the most common type of cerebral infarction. Atherosclerosis of the main cerebral artery or cortical branch leads to thickening of blood vessels, stenosis and occlusion of the lumen, and thrombosis, resulting in reduced or interrupted blood flow in the brain, cerebral ischemia and hypoxia leading to softening and necrosis, and focal neurological symptoms , is an acute cerebrovascular disease with a sudden onset, high mortality and disability rate among ischemic cerebrovascular diseases. [0003] Because the time allowed for endovascular treatment is extremely short, it is very easy to cause large-scale cerebral infarction, the physical fitness of ...

AI Technical Summary

Problems solved by technology

[0003] Due to the extremely short time allowed for endovascular treatment, it is very easy to cause large-scale cerebral infarction, the physical fitness of the elderly is poor, and the mortality and disability rates are high

At present, drug intravenous or arterial thrombolysis is mostly used to treat thrombus. Among them, the opening rate of intravenous thrombolysis is less than 30%, the opening rate of arterial thrombolysis is less than 60%, and the postoperative bleeding rate is as high as 10%.
