Abstract

The invention relates to a thrombus removal support, a thrombus removal device and a thrombus removal system. The thrombus removal support has a compressed state during conveying and an expanded state during thrombus removal, can elastically expand from the compressed state to the expanded state, and comprises a separating bracket for scraping a thrombus from the inner wall of a blood vessel; a supporting bracket, wherein the supporting bracket is connected to the far end of the separating bracket; and during thrombus removal, an inner cavity for containing the thrombus is defined by the separating bracket and the supporting bracket, an opening allowing the thrombus to enter the inner cavity is formed in the near end of the separating bracket, the elastic supporting strength of the separating bracket is higher than that of the supporting bracket, and the flexibility of the supporting bracket is higher than that of the separating bracket; and a filter screen film, wherein the filter screen film is at least connected with the supporting bracket, and the filter screen film is used for filtering the thrombus and passing blood. The thrombus removal device comprises the thrombus removal support, a traction catheter and an outer sheath tube. The thrombus removal system comprises the thrombus removal device and a thrombus breaking device.

Description

Technical field [0001] Technical Field The present invention relates to medical devices, and particularly to a stent thrombectomy, embolectomy and thrombectomy apparatus system. Background technique [0002] Venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE). [0003] Deep vein thrombosis (DVT) is a high incidence of vascular surgery disease, usually caused by abnormal venous blood clotting, so that the backflow of blood caused by obstruction. Pulmonary embolism (PE) has become the third leading cause of death from cardiovascular disease. Two risk factors for pulmonary embolism include environmental factors and personal factors, personal factors including age, previous history of VTE, history of cancer, heart and lung failure, congenital or acquired coagulation disorders, hormone therapy. PE can cause acute systemic hypotension and even heart failure, which causes the death of the patient. [0004] Therefore, as soon as possible quickly ...
