Abstract

A coronary atherosclerotic plaque taking-out device comprises a medical flexible fiber catheter, and is technically characterized in that a working part is arranged at the front end of the medical flexible fiber catheter, the tail end of the medical flexible fiber catheter is connected with a control handle, the working part comprises a cold light source, a micro camera and a plaque spatula with a flexible front end, the cold light source is connected with a power supply through a circuit, the micro camera is connected with a display screen through a data line, and the plaque spatula is connected with the control handle through a control cord. The operation with the device belongs to invasive operation, under the condition of trauma of a patient, the operation applicable symptoms are widened, and the operation is not limited by ages and nutritional conditions; no stent is placed inside the body, so that the probability of fever caused by endogenous infection is avoided, and the probability that the atherosclerotic plaque is formed again on the inner wall of a stent after operation is avoided; the therapeutic effect is better when the blockage happens at the early onset stage of a patient, the pain symptom of the patient is effectively controlled, myocardial infarction is prevented, and the death rate of patients is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a coronary atherosclerotic plaque removal device. Background technique [0002] As we all know, atherosclerosis is the most common and important type of arteriosclerosis, which is characterized by the deposition of lipids in the intima of the affected arteries, the accumulation of complex sugars, followed by fibrous tissue hyperplasia and calcium deposition, and arterial medial of lesions. The disease mainly involves large and medium-sized muscular elastic arteries, especially the aorta, coronary arteries, and cerebral arteries, often leading to serious consequences such as lumen occlusion or wall rupture and bleeding. Atherosclerosis that occurs in the coronary arteries is called coronary atherosclerosis. It is the most common form of stenotic coronary artery disease, especially atherosclerosis of extramural coronary branches. The reason why the proximal segment of th...
