Thrombus aspiration device for vascular surgery

Abstract

The invention discloses a thrombus aspiration device for vascular surgery. The device comprises a crushing drill bit, a thrombus fine crushing assembly, an inflation isolation assembly, a shell and a thrombus pull-back assembly, wherein the thrombus fine crushing assembly is mounted at one end of the crushing drill bit, the inflation isolation assembly is mounted at one end of the thrombus fine crushing assembly, and a middle rod is arranged at one end of the inflation isolation assembly; a shell is detachably connected to one end of the middle rod, a first motor is arranged on the inner surface of the shell along one end of the middle rod, the thrombus pull-back assembly is mounted at the right end of the inner surface of the shell, and belt wheels are rotated through a third motor, pull ropes are driven, and a sliding sleeve ring is pulled to move inwards; when the sliding sleeve ring and a first air bag move, blood isolated in the middle and all large and small thrombus can only be pushed by the air bag to move into a collecting cavity, and even tiny thrombus cannot escape due to the isolation effect of the air bag, so that the thrombus aspiration effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a thrombus suction device for vascular surgery. Background technique [0002] Vascular surgery is a branch of surgery, mainly aimed at the prevention, diagnosis and treatment of peripheral vascular diseases other than cerebrovascular and cardiovascular diseases. In addition to hair, nails, cornea, etc., the human body has blood vessels all over the body. Therefore, vascular surgery covers a wide range. 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 variable flow dependent patterns, thrombi consist of insoluble fibrin, deposited platelets, accumulated leukocytes, and trapped erythrocytes. [0003] However, the existing thrombus suction effect is not good. In the treatment of thrombus in blocked blood vessels, the clogged thrombus cannot be broken well, and adhes...

Problems solved by technology

[0003] However, the existing thrombus suction effect is not good. In the treatment of thrombus in blocked blood vessels, the clogged thrombus cannot be broken well, and adhesion residue is easy to appear. Many small thrombi escape from the interception in the gap and the filter, and the suction effect needs to be improved. For this reason, we provide a thrombus suction device for vascular surgery
