Abstract

The present invention relates to a device for mitral valve cerclage surgery for patients with mitral valve regurgitation. tension. The device for mitral valve cerclage surgery that protects the tissue of the coronary sinus and the tricuspid valve and transmits the knot to maintain the tension of the cerclage wire includes: (A) a tissue protection device (20), including: a tube for the coronary sinus (22) is a hollow cylindrical tube for protecting the coronary sinus tissue; the tricuspid valve tube (24) is a hollow cylindrical tube for protecting the tissue of the tricuspid valve and the ventricular septum; and the cadre (26) consists of the above-mentioned The tube for the coronary sinus and the tube for the tricuspid valve are respectively extended and fixedly combined with each other; and (B) the node transmission device (30), which is a hollow catheter and has an opening and closing part that can be opened and closed at the end of one side (32) A through hole (34) formed on a side surface of the opening and closing portion along the longitudinal direction.

Description

technical field [0001] The present invention relates to a mitral valve cerclage surgery device used for mitral valve cerclage surgery on patients with mitral valve regurgitation, which can safely and effectively transmit and maintain the final appropriate tension required for the cerclage surgery . Specifically, the present invention relates to a tissue protection device for protecting the coronary sinus and the tricuspid valve and their surrounding tissues during the mitral valve cerclage operation, passing the knot of the cerclage wire to the upper end of the above-mentioned tissue protection device to A knot transmission device for transmitting and maintaining a certain tension to a cerclage line, and a device for mitral valve cerclage operation including the two devices. Background technique [0002] The heart is an organ that acts as a blood pump. In order to operate the pump (heart) constituted by muscles, it is necessary to have a valve (valve) that allows blood to ...
