Abstract

The invention relates to a thrombus removing system which is suitable for removal of foreign matters such as thrombi, thrombus fragments, blood clots, blood lipid plaques and atherosclerotic substances in blood vessels and is also suitable for removing blood vessel thrombi formed on the inner surfaces of blood vessel stents placed in blood vessels of a human body and causing vascular endothelial hyperplasia. The thrombus removing system comprises a thrombus removal device and an operating handle portion, wherein the thrombus removal device is connected with the operation handle portion througha rear catheter; the thrombus removal device comprises a puncture head, a guide wire, a front catheter, a middle catheter, a front cannula, a front balloon, a front balloon catheter, a front supportsleeve, a front collection basket, a front thrombectomy device, a front catheter and middle catheter telescopic connection mechanism, a middle catheter and rear catheter telescopic connection tube, arear catheter, a rear catheter cannula, a rear balloon, a rear balloon catheter, a rear support sleeve, a rear collection basket, a rear thrombectomy device and a negative-pressure suction tube; the front thrombectomy device is arranged on the middle catheter at the rear portion of the front collecting basket; the rear thrombectomy device is disposed on the rear catheter in front of the rear collection basket.

Description

technical field [0001] The invention relates to a thrombus removal system, which belongs to the field of medical equipment, and is suitable for removing foreign objects such as thrombus, thrombus fragments, blood clots, blood lipid plaques, atherosclerosis, etc. Vascular thrombus formed on the inner surface of the vascular stent and cause vascular endothelial hyperplasia. Background technique [0002] A thrombus is a small piece of blood that forms on the surface of a vessel in the cardiovascular system where the lining has been peeled off or repaired. In the variable fluid-dependent type, the thrombus is composed of insoluble fibrin, deposited platelets, accumulated white blood cells, and trapped red blood cells. Thrombosis is a multifactorial process that interacts and influences each other with a set of genetic and environmental factors. Common clinical thrombosis patients, the main characteristics are familial heredity, recurrence, severity of symptoms, abnormal thrombu...
