本発明を詳述する。Each of the actuating jaw members is curved such that the respective edge of the hole engages with the curved portion of the respective actuating jaw member while the actuating jaw members are being moved apart and toward each other. It is convenient if the arm supporting the actuating jaw member has a protrusion arranged on the side of the arm opposite to the actuating jaw member and made to fix the ligature holder. Preferably, the protrusion is provided with a lock. The proposed prosthetic valve holder can provide reliable attachment of the prosthetic valve therein, and also allows the surface of the prosthetic valve to be attached to the surface of the atrioventricular fiber ring. The present invention allows rapid and precise apposition, and the ability to quickly attach or detach the valve from the holder, thereby reducing surgical time and eliminating the possibility of redundancy or complete obstruction of the surgical field. The invention will now be described in detail with reference to the accompanying drawings, in which preferred embodiments of the invention are shown.

にする。A holder for a prosthetic valve, for example a heart prosthesis, comprises two arms 1.2 which are connected to each other via a T-shape 3 and have a box-shaped lock 4. Each arm 1, 20 is provided with a handle 5 or 6 at one end, and three actuating jaw members 7 at the other end of the arm 2.
8.9 is supported. When the respective ends of the actuating jaw members 7, 8.9 are separated, they form a circle and are equally spaced along the circle, i.e. the actuating jaw members 7, 8.9. The number of actuating jaw members 7, 8.9, which are spaced 90 degrees apart in a circumferential plane passing through their working ends, may be increased. In that case, as mentioned above, the ends of the actuating jaws should be equally spaced apart on the circumference. Since the valve remains stable on at least three points on the support member, the provision of three or more actuating jaws 7, 8, 9 provides reliable fixation of the artificial valve 10 on the actuating jaws. enable.

む。Since the artificial valve holder of the present invention allows the surface of the artificial valve collar to be accurately juxtaposed to the surface of the atrioventricular fiber ring,
The prosthetic valve can be quickly and precisely aligned to a predetermined position. This allows for reliable fixation of the valve in the holder, has the possibility of fast fixation and removal from the holder, and also has the advantage of providing a reliable fixation of the valve in the holder, as well as the possibility of fast fixation and removal from the holder, and furthermore, when accessing the surgical field, i.e. the entire surgical field. It can be obtained by eliminating the possibility of interference. This allows good visualization of the surgical area and allows convenient sewing of the prosthetic valve to the atrioventricular fiber ring. All of this significantly reduces the operative time, and the valve installation allows the surgeon to correct the above deficiencies more precisely, yielding better results within the postoperative period.
