Abstract

The invention relates to the technical field of medical instruments, and discloses a filter screen assembly for pulmonary embolism thrombus removal and a thrombus suction assembly. The filter screen assembly comprises a thrombus breaking filter screen, a first isolation filter screen and a second isolation filter screen which can radially and elastically expand and are coaxially arranged, and thethrombus breaking filter screen is arranged between the first isolation filter screen and the second isolation filter screen. The thrombus suction assembly comprises a thrombus suction tube, a thrombus output tube, a thrombus sucker and a connecting base with a hollow channel. The hollow channel is used for allowing the stored filter screen assembly to penetrate through; the thrombus suction tubeis arranged at the front end of the connecting base, a flexible sealing valve is arranged at an opening in the rear end of the connecting base, the inner end of the thrombus output tube is connected with the side face of the connecting base, and the outer end of the thrombus output tube is connected with the thrombus sucker. The embodiment of the invention can effectively remove large thrombus ofthe pulmonary embolus, reduce the operation complexity and shorten the operation time.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a filter assembly and a thrombus suction assembly for removing pulmonary embolism thrombus. Background technique [0002] Acute pulmonary embolism (PE) is a common cardiovascular system disease in my country. It is a clinical and pathophysiological syndrome of pulmonary circulation disorder caused by endogenous or exogenous emboli blocking the pulmonary artery. It is often caused by deep vein thrombosis of the lower extremities. As a result, the fatality rate is high, which seriously endangers the health and quality of life of patients. Pulmonary thromboembolism is the most common type of acute PE, and deep vein thrombosis is the main source of thrombus that causes pulmonary thromboembolism. [0003] Acute pulmonary embolism is an acute development of pulmonary circulation disorders, the most important is that patients have symptoms of dyspnea, chest tightness, and even d...
