Problems solved by technology

[0003] At present, patients with multi-stage extremity arteriosclerotic occlusive disease usually adopt surgical methods, including artificial vascular bypass and intra-arterial stenting. Complete stripping and elimination of atherosclerotic plaques will lead to poor surgical results, and it will only play a new role in restoring blood flow. Device that peels off without obstructing blood flow solves the problem

Abstract

The invention discloses an adjustable endovascular exfoliator which comprises a fixing mechanism, a driving mechanism is fixedly arranged on the right side of the fixing mechanism, a moving mechanism is slidably arranged outside the driving mechanism in a sleeving mode, and a plurality of spokes capable of exfoliating angiosclerosis plaques are fixedly arranged on the right side of the fixing mechanism in a surrounding mode. The right side of the spoke is fixedly connected with the moving mechanism, the driving mechanism is sleeved with a pushing mechanism capable of driving the moving mechanism to move leftwards or rightwards in a threaded mode, the pushing mechanism is rotationally connected with the moving mechanism, and scales allowing the moving distance of the pushing mechanism to be observed are integrally arranged outside the driving mechanism. According to the adjustable endovascular exfoliator, a surgeon can tighten up the spokes, and exfoliating treatment is carried out on plaques in a blood vessel through the tightened spokes, so that by using the adjustable endangium exfoliating device, angiosclerosis plaques can be exfoliated and eliminated, and the surgical treatment effect is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable vascular intima stripper. Background technique [0002] Atherosclerotic occlusive disease of the extremities is a chronic arterial occlusive disease caused by atherosclerotic lesions. Due to atherosclerotic plaque, arterial medial degeneration and secondary thrombosis, the lumen is gradually occluded, causing ischemia in the limbs. . [0003] At present, patients with multi-stage extremity arteriosclerotic occlusive disease usually adopt surgical methods, including artificial vascular bypass and intra-arterial stenting. Complete stripping and elimination of atherosclerotic plaques will lead to poor surgical results, and it will only play a new role in restoring blood flow. A device that exfoliates without obstructing blood flow solves the problem. Contents of the invention [0004] The technical problem to be solved by the present invention is to provid...
