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. To make it possible to easily detach the actuating rod with the tool from the guide tube and from the holder, the actuating rod is designed such that it passes through the guide sleeve in one piece. Moreover, it is detachably connected to the actuating lever by a rod coupling, while the guide tube is rigidly and especially nonrotatably connected to the guide sleeve.
