Handle

摘要

A handle of a surgical instrument including a shaft, a handle body, a stationary handle lever, with a movable handle lever, with a receptacle that is disposed on the movable handle lever for a proximal end piece of an actuating rod that extends through the shaft, at the distal end of the shaft, an end effector, wherein the receptacle receives or releases, in the receiving position of the movable handle lever, the end piece for assembly or disassembly of the shaft, and with a handle spring that applies force to the movable handle lever when the actuating rod is not installed, and on a stop means on the movable handle lever. The handle includes a deactivation means that deactivates the application of force to the movable handle lever by means of the handle spring, when the actuating rod is installed on the handle.
