An atrial appendage forceps comprising a first clamp arm (1) and a second clamp arm (2) provided symmetrically, in the first clamp arm (1) and the second clamp arm (2) The first cavity (11) and the second cavity (21) provided along the axial direction thereof are provided correspondingly, and the first cavity (11) and the second cavity (21) are provided in the first cavity (11) and the second cavity (21). The first spring (12) and the second spring (22) are provided corresponding to each other, and the first spring (12) is connected to the second clamp arm (13) via the first tension thread (13). 2), the second spring (22) is connected to the first clamp arm (1) via the second tension thread (23), thereby forming a closed ring structure, and the first clamp arm (1) and the second clamp arm (2) can be expanded and contracted by the first spring (12) and the second spring (22). It can be accompanied by opening and closing. By providing the springs (12, 22) in the clamp arms (1, 2), the external dimensions of the atrial appendage forceps are reduced, the pressure and wear on the peripheral tissue of the atrial appendage are reduced, and the thickness of the auricular appendage is increased. In addition, since the amount of deformation of the springs (12, 22) increases, a larger closing force can be provided. By covering the atrial appendage with the entire closed ring structure, it is possible to prevent the clamp arm from overflowing after the atrial appendage is crushed. The atrial appendage forceps has a sophisticated structure design, a stable and reliable closing force, is easy to operate, is safe and effective.心耳鉗子であって、対称に設けられた第１のクランプアーム（１）及び第２のクランプアーム（２）を含み、第１のクランプアーム（１）及び第２のクランプアーム（２）内には、その軸方向に沿って設けられた第１の空洞（１１）及び第２の空洞（２１）が対応して設けられ、第１の空洞（１１）及び第２の空洞（２１）内には、第１のバネ（１２）及び第２のバネ（２２）が対応して設けられ、第１のバネ（１２）は、第１の引張糸（１３）を介して第２のクランプアーム（２）に接続され、第２のバネ（２２）は、第２の引張糸（２３）を介して第１のクランプアーム（１）に接続、これによって閉環構造が形成され、第１のクランプアーム（１）と第２のクランプアーム（２）は、第１のバネ（１２）及び第２のバネ（２２）の伸縮に伴って開閉することができる。バネ（１２，２２）をクラ
