摘要：
FIELD: medicine.SUBSTANCE: surgical instrument contains a rod, an end effector and a trigger actuator. The trigger actuator comprises a rotating primary shaft and a flexible secondary shaft. The rotating primary shaft comprises a threaded transfer portion. The primary shaft can rotate in the first direction and in the second direction. The flexible secondary shaft comprises a thread operatively engaged with the threaded transfer portion. The flexible secondary shaft contains a longitudinal axis. The flexible secondary shaft is limited in rotation around the longitudinal axis. The rotating primary shaft is adapted to move the flexible secondary shaft to the end effector when the rotating primary shaft is rotated in the first direction. The rotating primary shaft is adapted to move the flexible secondary shaft from the end effector when the rotating primary shaft rotates in the second direction. The flexible secondary shaft comprises a housing, the thread comprises a spring including a plurality of turns. The housing passes through the plurality of turns. In the second embodiment, the above surgical instrument comprises a rod, an end effector, a hinge joint, and a trigger actuator. The end effector comprises a movable cutting member. The end effector is movable relative to the rod around the hinge joint. The flexible secondary shaft is functionally engaged with the cutting member. The flexible secondary shaft comprises a flexible body including a proximal end, a distal end, a plurality of interconnected portions of the grid and a thread. The plurality of interconnected portions of the grid passes between the proximal end and the distal end. The thread is designed to limit the external movement of the plurality of interconnected portions of the grid. The rotating primary shaft is adapted to move the flexible secondary shaft to the end effector when the rotating primary shaft is rotated in the first direction. The flexible body contains a longitudinal hole extending thr
