Abstract

The invention provides a high-speed rotary grinding mechanism and an intrusive rotary grinding device. The rotary grinding mechanism comprises a guide wire and shaft assembly, an output connector, a track tube assembly and a temperature detection assembly, the track tube assembly comprises a sheath tube of a cylindrical structure, and a mounting hole penetrating in the axial direction of the sheath tube is formed in the side wall of the sheath tube; the temperature detection assembly comprises a thermocouple detection end and a thermocouple wire which are connected with each other, the thermocouple wire is inserted into the mounting hole, and the thermocouple detection end extends out of the end part of the sheath tube; the shaft assembly comprises a rigid shaft and a flexible shaft which are connected with each other, the flexible shaft comprises an inner-layer coil assembly and an outer-layer coil assembly which are attached and are opposite in winding direction, and at the two ends of the flexible shaft, spring wires are connected in a welded mode; and the flexible shaft is provided with two or three rotary grinding layers at intervals so as to grind a same plaque, and the rotary grinding layer on the outermost side is located at the end of the flexible shaft. The device can adapt to a wider blood vessel range, and the operation safety is higher.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a high-speed rotational atherectomy mechanism and an interventional atherectomy device. Background technique [0002] Interventional medical equipment is a commonly used equipment in existing medical technology, such as atherosclerosis and other diseases, ischemic heart disease has gradually become one of the most lethal diseases, and its cause is mainly atherosclerosis: Fat, fiber, and calcium deposit on the blood vessel wall to form plaques, which hinder the normal circulation of blood and cause blood vessel blockage. In the existing technology, interventional balloons and stents are often used to push the atherosclerotic plaque into the blood vessel wall to dredge the blood vessels and treat ischemic heart disease and peripheral arterial disease. However, for severely calcified lesions, as well as lesions in special locations, such as joints, because the internal spac...
