The present invention relates to a device for a mitral valve membrane cerclage procedure that can maintain the tension of a cerclage string at a certain level and maintain the effect of choking the mitral annulus via the cerclage string during a mitral valve membrane cerclage procedure on mitral regurgitation patients, so as to increase the success rate of mitral valve membrane cerclage procedures. The device for a mitral valve membrane cerclage procedure of the present invention comprises: a tissue protecting tube (20) including a coronary sinus tube (22) that is a hollow cylindrical tube for protecting coronary sinus tissue, a tricuspid valve tube (24) that is a hollow cylindrical tube for protecting the tricuspid valve and the ventricular septum tissues, and a stem portion (26) from which the coronary sinus tube and the tricuspid valve tube respectively extend and are fixed and coupled to one another and which is formed having a catching ledge (28) on the outer surface thereof; and a cap (30) that is a structure that is hollow inside so that the tissue protecting tube can be inserted therein, and which has a blocking plate (31) formed on a top surface thereof, at least two through-holes (32) formed in the blocking plate (31), and a catching projection (35) formed corresponding to the catching ledge of the tissue protecting tube, wherein the catching ledge (28) of the tissue protecting tube and the catching projection (35) of the cap have a structure that facilitates the mutual separation of the tissue protecting tube and the cap and does not easily permit mutual insertion by means of catching therebetween. |
