摘要：
A surgical operating instrument comprises an instrument body (10), a rotary ring (20), a triggering handle (30), and a rack (102) fitting the triggering handle (30). The rack (102) can move from a proximal end to a distal end of the surgical operating instrument under the action of the triggering handle (30). The surgical operating instrument further comprises a rotary ring action member (104). The rotary ring (20) is set to be allowed to rotate around the axis of the surgical operating instrument when the surgical operating instrument is in an initial state. The rack (102) makes contact with the rotary ring action member (104), and exerts an acting force on the rotary ring action member (104) towards the proximal end of the surgical operating instrument. When the surgical operating instrument is in closed and triggered states, the rack (102) is separated from the rotary ring action member (104), the rotary ring action member (104) makes contact with an inner wall surface (202) of the rotary ring, and applies a tensile force to the rotary ring (20) at least in the radial direction of the rotary ring (20). The surgical operating instrument can prevent the rotary ring (20) from rotating by mistake when the surgical operating instrument is in the closed and triggered states, avoid harms to human tissues, and reduce surgical risks.La présente invention concerne un instrument d'opération chirurgicale qui comprend un corps d'instrument (10), un anneau rotatif (20), une poignée de déclenchement (30), et un montage (102) raccordé à la poignée de déclenchement (30). Le montage (102) peut se déplacer d'une extrémité proximale vers une extrémité distale de l'instrument d'opération chirurgicale sous l'action de la poignée de déclenchement (30). L'instrument d'opération chirurgicale comprend en outre un élément d'actionnement d'anneau rotatif (104). L'anneau rotatif (20) est configuré pour pouvoir tourner autour de l'axe de l'instrument d'opération chirurgicale lorsque l'instrum
