A medical instrument comprises a hollow shank. An instrument section is arranged pivotable to the hollow shank, in the proximity of the distal end of this hollow shank. An instrument part is mounted in an axially movable manner in the pivotable instrument section. This instrument part which may be a part acting in a direct manner on organs, tissue or likes, or preferably serves for movement coupling to such a part in the bendable instrument section, is coupled in movement via a forcibly guided multi-joint arm, to an actuation means which is axially movably guided in the hollow shank.
