Medical instrument

A medical instrument comprising:

• a hollow shaft having a proximal end and a distal end, whose proximal end is adapted to be connected to an operating unit and having a tool tip arranged on the distal end of the shaft having a tool arranged on a distal end of the tool tip, wherein the tool has two jaw parts, which can be pivoted relative to one another and wherein the jaw parts are pivoted via actuating elements, which are mounted so as to be axially displaceable in the shaft and which can be actuated on the proximal end via the operating unit, and wherein the tool tip can be pivoted via a joint mechanism relative to a longitudinal axis of the shaft,
• characterized in that the pivotable jaw parts are each coupled via an articulated drive element to a distal end of an actuating element mounted so as to be axially displaceable in the shaft such that the articulated drive element extends between the distal end of the shaft and a proximal end of the tool tip, wherein the articulated drive element includes at least one roller chain, wherein the at least one roller chain includes a plurality of chain links and is mounted in a region of the tool tip so as to be articulated as a link chain and mounted with its free end on one of the pivotable jaw parts, and wherein the link chain is designed as a bolt chain.
