Technical Field
[0001] The utility model relates to the technical field of medical appliances, in particular to a Y-shaped connecting tube for thrombus aspiration. Background Art
[0002] Thrombi are small pieces of blood formed on the surface of the peeling or repaired inner surface of the cardiovascular system blood vessels. Thrombi are composed of insoluble fibrin, deposited platelets, accumulated white blood cells and trapped red blood cells. Thrombosis is a multifactorial process involving many genetic and environmental factors that interact with each other.
[0003] Thrombus aspiration surgery is a commonly used medical method in the prior art, that is, a thrombus aspirator is used for surgery, and a suction tube is inserted into the affected area for surgical operation. In actual use, since a variety of medical fluids (such as saline solution, etc.) need to be injected during the operation, the machine needs to frequently replace the connecting tubes during use to achieve the medical purpose. This method of repeated plugging and unplugging is more troublesome and easy to cause contamination.
