Abstract

The present invention provides a catheter for removing a thrombus, which is characterized by comprising: a catheter body: a stent for removing a bolus, which is arranged at a position close to the end of the catheter body; a handle, which is connected to the other end of the catheter body; a camber adjusting device , is connected between the handle and the catheter body to adjust the curvature of the catheter body, and then adjust the angle of the bolt removal bracket. The beneficial effect of the technical solution is that the thrombectomy stent has an adjustable curvature, and the stent curvature can be adjusted according to the patient's blood vessel curvature, so as to quickly pass through the blood vessel and reach the thrombus position; the operation time and the number of surgical instruments can be reduced, and the stent can be adjusted according to the patient's blood vessel curvature. The thrombectomy stent has a spring device inside, which can effectively control the stress and strain of the thrombectomy stent during stretching, and the 3-layer mesh disk stent structure can effectively grasp the thrombus.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a stent catheter for thrombectomy. Background technique [0002] Thrombosis refers to the pathological process in which the formed components in the circulating blood form emboli in the blood vessels under certain conditions, resulting in partial or complete blockage of the blood vessels and obstruction of blood supply in the corresponding parts. A thrombus is a blood clot formed in the vascular system of a living body. It is not affected by the blood flow in the blood vessel, so its structural characteristics are different from the blood clot formed in a resting state in vitro. Thrombosis can be found in atrioventricular cavities, arteries, veins, and capillaries. Clinically, acute events caused by thrombosis include acute myocardial infarction, ischemic stroke, pulmonary embolism and disseminated intravascular coagulation, which are often life-threatening. Thrombosi...
