Abstract

The invention relates to the technical field of medical equipment, in particular to a rotary cutting device. The rotary cutting device comprises a cutting assembly extending into a blood vessel for cutting, a driving device for driving the cutting assembly to move and a protective casing arranged relative to the cutting assembly, and the head of the cutting assembly is located on the inner side ofthe protective casing relative to the extending direction of the blood vessel. The rotary cutting device has the advantage that the inner wall of the blood vessel is not damaged during the rotary cutting process.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a rotary cutting device. Background technique [0002] Peripheral vascular thrombosis is mainly due to slow blood flow and changes in blood viscosity on the basis of vascular stenosis or occlusion caused by atherosclerosis and atrial thrombus shedding. In recent years, the application of endovascular technology in the treatment of arteriosclerotic occlusive diseases tends to be extensive, and its development has gone through major stages such as percutaneous transluminal angioplasty, stent placement, and volume reduction technology. For the old thrombus in the blood vessel, it is generally necessary to perform rotary cutting on the thrombus or plaque in the diseased blood vessel. The devices used are such as the existing patent document CN101795630B, rotary cutting device, system and method, and CN103957825B, atheromatous plaque removal device , system and method, alth...
