Handle

A handle of a surgical instrument comprising:

• a shaft;
• a handle body;
• a stationary handle lever that is stationary on the handle body;
• a movable handle lever that is movably disposed on the handle body;
• a receptacle that is disposed on the movable handle lever to receive or release a proximal end piece of an actuating rod that extends through the shaft;
• an end effector disposed on a distal end of the shaft;
• a handle spring that applies force to the movable handle lever when the actuating rod is not installed, and is supported on the stationary handle lever or on the handle body on one end, and on a stop on the movable handle lever, on another end such that the movable handle lever is moved to a receiving position;
• a deactivation mechanism that deactivates an application of force to the movable handle lever by using the handle spring, when the actuating rod is installed on the handle, wherein:
• the receptacle is configured to receive or release, in the receiving position of the movable handle lever, the proximal end piece for assembly or disassembly of the shaft on the handle;
• the deactivation mechanism includes a movement element that causes deactivation and that is movably disposed between a deactivating and a non-deactivating position;
• and
• the movement element is disposed and configured such that, in the non-deactivating position, the movement element constitutes the stop for the handle spring, and the movement element releases the handle spring in the deactivating position.
