Abstract

The invention relates to a thrombus removal system. The thrombus removal system comprises a thrombus removal support and a traction catheter, wherein the traction catheter is connected with the thrombus removal support, the thrombus removal support is used for scraping a thrombus of the inner wall of a blood vessel, and the scraped thrombus enters the thrombus removal support; a thrombus breaking support and a conveying pipe which are both connected into the traction catheter in a sliding mode. In which, the conveying pipe is connected with the thrombus breaking support so as to drive the thrombus breaking support to be discharged from the far end of the traction catheter and enter the thrombus removal support, and the conveying pipe is used for driving the thrombus breaking support to rotate in the thrombus removal support along a circumferential direction to conduct thrombus breaking; and after thrombus breaking, the conveying pipe can further be used for driving the thrombus breaking support to enter the traction catheter from the far end of the traction catheter and driving the thrombus breaking support to be discharged from the near end of the traction catheter.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thrombectomy system. Background technique [0002] Venous thromboembolism (VTE) includes deep vein thrombosis (DVT) and pulmonary embolism (PE). [0003] Deep vein thrombosis (DVT) of the lower extremities is a high-incidence vascular surgical disease, which is mostly caused by abnormal coagulation of blood in the veins of the lower extremities, resulting in obstruction of blood return. Pulmonary embolism (PE) has become the third leading cause of cardiovascular death. Risk factors for pulmonary embolism include both environmental and personal factors. Personal factors include age, previous VTE history, cancer history, cardiopulmonary failure, congenital or acquired coagulation disorders, and hormone therapy. Acute PE can lead to systemic hypotension and even heart failure, which can lead to patient death. [0004] Therefore, early, rapid and effective thrombus remov...
