Description

Technical Field

[0001] The utility model belongs to the technical field of thrombus aspiration, and in particular relates to a thrombus aspirator. Background Art

[0002] Thrombi are small pieces of blood formed on the surface of the peeling or repaired parts of the inner surface of the cardiovascular system. In the variable fluid-dependent type, thrombi are composed of insoluble fibrin, deposited platelets, accumulated white blood cells and trapped red blood cells. In clinical vascular surgery, thrombi need to be extracted. It is necessary to use a thrombus extractor to absorb the thrombus in the blood vessel. When using existing thrombus extractors, they are generally connected by combining an extraction tube with a collection bottle for thrombus extraction. When the extraction tube and the collection bottle are connected, most of them are fixed by plugging. When this connection method is assembled and used, due to the problem of no limiting structure, it will lead to an unstable connection and it is very easy to separate when pulled. For this reason, we propose a thrombus extractor. Utility Model Content
