Thrombus cleaning brush device

Abstract

The invention discloses a thrombus cleaning brush device. The thrombus cleaning brush device comprises a guide wire and a micro-catheter, the guide wire is arranged in the micro-catheter; the guide wire is composed of a core and a sheath outside the core; the sheath comprises a spiral sheath and a coating sheath; the spiral sheath is used for spiral winding and covering outside the core at the head of the guide wire; the coating sheath is used for covering outside the core at the tail part of the guide wire; the core at a brush part is sleeved with a spiral guide wire; and brushes arranged inan outward radiation manner are clamped on the spiral guide wire. The thrombus cleaning brush device is simple in structure, convenient to operate, low in cost, capable of being produced in batches, capable of effectively cleaning endovascular thrombus, capable of being repeatedly used and remarkable in social and economic benefits, and damage to endovascular membranes due to multiple times of operation is avoided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a thrombus cleaning brush device. Background technique [0002] With the advent of an aging society, the incidence of atherosclerotic diseases continues to increase. As atherosclerotic plaques cause vascular lumen narrowing, once the plaques are inflamed or ruptured, blood clots will form on the damaged inner surface of the blood vessels. Blockage is thrombosis, which will lead to sudden stenosis and even acute occlusion of the vascular lumen. In a short period of time, once the stenosis and occlusion of the vascular lumen become severe, it will lead to acute ischemia and hypoxia of the tissues and organs in the blood supply area, and even necrosis. Cerebral infarction can occur in the brain, and acute myocardial infarction can occur in the heart. Of course, it can also occur in other organs and blood vessels in the body. It is a clinical emergency and has become a serious threat...
