  • Patent number: 5607449
    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.
