Clamper for repairing valve leaflet

Abstract

The invention relates to the technical field of medical instruments and discloses a clamper for repairing valve leaflet. According to the clamper for repairing the valve leaflet, a locking assembly isdriven to move back and forth by a push-pull actuating rod to enable a main body frame to be inserted into or separated from a first through groove, simultaneously a first clamping elastic piece anda second clamping elastic piece can have elastic deformation to clamp the position to be clamped on the valve leaflet, and after the valve leaflet is clamped by the first clamping elastic piece and the second clamping elastic piece, outward expanding of the first clamping elastic piece can also be limited by utilizing the two opposite side walls of the first through groove, and it is ensured thatthe valve leaflet clamped between the first clamping elastic piece and the second clamping elastic piece does not fall out. Compared with an existing clamper, the clamper for repairing the valve leaflet has fewer parts, is simple in structure and convenient to operate, the operation time is shortened, and the clamping stability of the valve leaflet is enhanced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a holder for valve leaflet repair. Background technique [0002] The heart has four valves, the valve between the left atrium and the left ventricle is the mitral valve, the valve between the right atrium and the right ventricle is the tricuspid valve, the valve between the aorta and the left ventricle is the aortic valve, and the valve between the pulmonary artery and the right ventricle The valve is the pulmonary valve. Normal valves maintain a one-way flow of blood by opening and closing according to the pressure difference on each side, ensuring that blood is pumped out of the chambers and not backed up. Many diseases, such as rheumatic heart disease and endocarditis, cause valvular lesions that impair the function of the valve, among which stenosis and regurgitation are common valvular diseases. Stenosis is caused by a valve that cannot open fully, resulting in...

AI Technical Summary

Problems solved by technology

The main principle is to suture the prolapsed mitral valve leaflet / tricuspid valve leaflet with the corresponding anterior leaflet or posterior leaflet to form a double-hole mitral valve edge midpoint suture, thereby reducing mitral regurgitation, while The blood flow into the left ventricle is not affected when the mitral valve opens during diastole, but MitraClip still has the following problems: complex structure, difficult valve leaflet clipping, long operation time, etc.
