Abstract

The invention discloses a thrombus suction device for vascular surgery, belongs to the technical field of medical equipment, solves the problems that a large number of thrombus fragments are generated in the prior art, all the fragments cannot be sucked in the suction process, and thrombus residues are caused, and comprises a tube body used for stretching into a blood vessel with thrombus, the tube body is used for stretching into a blood vessel with thrombus, an inner ring suction tube is movably arranged in the tube body, an outer ring suction tube is movably arranged outside the inner ring suction tube in a sleeving mode, and a telescopic system and a negative pressure tube are fixedly connected to the ends, close to the interior of the tube body, of the inner ring suction tube and the outer ring suction tube, so that the mode of breaking thrombus by rotating is improved, and the generation of thrombus debris is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a thrombus suction device for vascular surgery. 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 form, the thrombus consists of insoluble fibrin, deposited platelets, accumulated leukocytes, and trapped erythrocytes. Thrombosis is a multifactorial change process in which a group of genetic and environmental factors interact and influence each other. The main characteristics of common clinical thrombosis patients are familial heredity, recurrence, severity of symptoms, abnormal thrombosis site, and younger onset time. Suspicion of arterial or venous thrombosis or thromboembolism requires objective evidence. Angiography is the reference standard for diagnosis, but ultrasonography, performed wi...
