The systems described herein include a surgical instrument having a shaft with a fixed handle part having a sliding part arranged thereon, and axially movable by means of a pivotable handle. The sliding part is guided on the shaft within an axial working stroke by proximal and distal guidance means. Locking means limit the axial displacement of the sliding part on the proximal end of the working stroke. In use, after unlocking the locking means, the sliding part is movable beyond the proximal end of the working stroke into a cleaning position, in which the distal guidance means are disengaged, so that the sliding part can be lifted away from the shaft. The proximal guidance means has two walls, which are arranged so they are axially parallel and guide the sliding part on the shaft. A link slot, having a pin engaged therein, is formed in each wall to guide the sliding part which is held in contact with the shaft within the working stroke.
