In addition to hair, nails, cornea, etc., the human body has blood vessels throughout the body. Vascular surgery covers a wide range. Thrombi are small pieces of blood formed on the surface of the peeling or repaired 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. The thrombus aspiration device can effectively remove thrombi by aspirating them out of the body and cooperating with catheter thrombolysis. The use of this device can significantly reduce the dosage and time of thrombolytic drugs, reduce the risk of severe complications such as massive bleeding, achieve minimally invasive treatment effects, and effectively improve the treatment efficiency within a limited time. Suspended thrombi and thrombogenic substances can be directly aspirated.
