Cleaning device applied to thrombus prone to falling off in blood vessel

Abstract

The invention discloses a cleaning device applied to thrombus prone to falling off in a blood vessel. The cleaning device comprises an interventional tube, a first telescopic tube is arranged at the interventional end of the interventional tube and can stretch out and draw back in the axial direction of the interventional tube, one end of the first telescopic tube is connected with the interventional tube, a connecting block is arranged at the other end of the first telescopic tube, and multiple elastic baffles are arranged between the connecting block and the interventional tube; a pluralityof inner supporting plates are further arranged on the circumferential outer wall of the interventional tube; one end of each inner supporting plate is hinged to the interventional tube, an inner supporting ball is arranged at the other end of each inner supporting plate, a movable assembly is arranged between each inner supporting plate and the interventional tube, an elastic first movable plateis arranged in each inner supporting plate, an elastic second movable plate is arranged in each first movable plate, and each first movable plate is further provided with an outlet matched with the corresponding first movable plate. When thrombus which is easy to move in a blood vessel is cleaned, the blood vessel can be expanded, the thrombus is prevented from being pushed to move in the blood vessel, and the thrombus can be conveniently and rapidly cleaned out of the blood vessel.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a cleaning device for easy-losing thrombi in blood vessels. 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 in which a set of genetic and environmental factors interact and influence each other. Common clinical thrombosis patients, the main characteristics are familial heredity, recurrence, severity of symptoms, abnormal thrombus formation site, and younger onset time, suspicion of arterial or venous thrombosis or thromboembolism requires objective evidence of angiography The standard of reference for diagnosis, but superficial blood ve...

Problems solved by technology

[0003] At present, when the existing thrombus cleaning equipment cleans the thrombus in the blood vessel, it usually uses the tip of the device to pass through the thrombus in the blood vessel, and then uses the expandable metal mesh at the tip to move back, pulling the thrombus to move along with it , so as to achieve the purpose of cleaning the thrombus in the blood vessel, but for the thrombus that is easy to fall off from the inner wall of the blood vessel, because the metal structure that is expanded and expanded is set on the tip, it also has a certain thickness when it is not expanded. When passing through a thrombus that is easy to fall off, it is not easy to pass through the thrombus smoothly, and it is easy to push the thrombus to move in the blood vessel, resulting in the failure to remove the thrombus smoothly
