1. A medical instrument comprising: a hollow shaft having a proximal end and a distal end, 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 one or more actuating elements, which are mounted so as to be axially displaceable in the shaft and which can be actuated on the proximal end, and wherein the tool tip can be pivoted via a joint mechanism relative to a longitudinal axis of the shaft,
characterized in that the jaw parts are each coupled via an articulated drive element to a distal end of one of the one or more actuating elements such that the articulated drive element spans a region of the joint mechanism between the distal end of the shaft and a proximal end of the tool tip, wherein the articulated drive element is a roller chain that is mounted so as to be guided in a region of the tool tip and articulated as a link chain and wherein the link chain is designed as a bolt chain.
