Abstract: The invention relates to a shaft for a medical instrument (12), in particular a homopolar or bipolar medical instrument, comprising a shaft member (16) that accommodates a tool (18) at the distal end, said tool (18) being provided with a first jaw part (19) and a second jaw part (21) which can be moved relative to each other from an open position (29) into a closed position (28) by a draw bar/push rod (26) that is guided inside the shaft member (16); at the proximal end, the shaft member (16) has a connecting piece (14) for attachment to a manipulating device (23) that allows the draw bar/push rod (26) to be moved back and forth; at the distal end, each jaw part (19, 21) is pivotally guided inside the shaft member (16) by means of a sliding block (49).

Abstract: The invention relates to a surgical instrument with a main part and at least one movable part movable relative thereto, with a handle arranged on the main part and having a stationary handle portion and a handle portion which can actuate the movable part. A locking device is provided in which, in a first position, the movable part is arranged in an initial position, and in a second position, the movable part can be changed over into a cleaning position and the movable part in this position is arranged captive with respect to the main part.

Abstract: The tubular-shaft surgical instrument is provided with an actuating rod for the manual operation of a forceps-like or scissors-like tool, which actuating rod is guided axially movably in a guide tube. The tool is mounted at the free end of the guide tube, and it has at least one tool part pivotable around a pivot axis extending at right angles to the axis of the tube. The tool is detachably mounted in the front end of the guide tube in the manner of a bayonet catch. The actuating rod is connected at its rear end, by a detachable connection, to an actuating lever, which in turn is pivotably mounted on a holder provided with a handgrip. A guide sleeve, which is coaxial with the guide tube, and in which the actuating rod is prevented from rotating in relation to the guide tube by manually detachable rotation-preventing elements, is arranged in the holder.
