Description

Multi-stage inching circulating spot removing device for cardiology department

Technical Field

The invention relates to the field of medical instruments, in particular to a multi-stage inching circulating speckle removing device for cardiology.

Background

Coronary artery calcification, i.e., calcification of atherosclerosis, as well as bone formation, is a complex, organic, regulated, and active process that is one of the manifestations of atherosclerosis. At present, the treatment mode of a patient with severe coronary vessel calcification disease in a hospital is to adopt an olive-shaped rotary grinding head with diamond particles, eliminate all soft, fibrous and calcified morphological plaques according to the principle of differential cutting or selective cutting, form a smooth lumen channel, eliminate or reduce the pneumatic trauma of a vessel wall and minimize the stretching and elastic retraction of the vessel wall. Because of the rotary grinding head diameter is fixed, the rotary grinding heads with different specifications need to be continuously replaced during treatment, so that the contact area of the abrasive drill and calcified plaques in blood vessels of patients is constant, the abrasive drill can only crush the local area of the calcified plaques, and the calcified plaques which are not crushed are still remained in the blood vessels of the patients, thereby causing injury to the patients.
