Claim Text:
1. A medical instrument, in particular for endoscopic purposes, comprising: a shaft, a handle positioned on a proximal end of the shaft, a tool positioned on a distal end of the shaft with two jaw members that can be displaced between an open position and a closed position, and an actuating element by which the handle and the tool are in active connection with one another for opening and closing the jaw members, wherein every jaw member of the tool is configured as a jaw member that consists of an inner cheek and an outer cheek, which are connected with one another on a distal end of every jaw member and are at a distance from one another in a proximal direction, wherein the inner cheek and the outer cheek of every jaw member are connected with one another by a framework of at least one connecting brace which is positioned between the inner cheek and the outer cheek so that every jaw member can be deformed under force impact by deforming the inner cheek and the outer cheek of the respective jaw member, wherein the inner cheek and the outer cheek of each jaw member are configured differently with respect to a cross-section shape, so that the inner cheek is of wider configuration than the outer cheek and the outer cheek of each jaw member is rounded or stepped in configuration on its outside, wherein the at least one connecting brace is configured to have a first width dimension, the first width dimension being measured in a direction transverse to a longitudinal direction of each jaw member and along the inner cheek of each jaw member, the at least one connecting brace is configured to have a second width dimension being measured in the direction transverse to the longitudinal direction of each jaw member and along the outer cheek of each jaw member, said first width dimension being larger than the second width dimension, and wherein the inner cheeks of both jaw members are directly and transition-free connected with one another on their proximal ends as a contact point for the actuating element and wherein the inner cheeks are configured as cast directly onto the actuating element to achieve a direct connection free of play between the actuating element and the tool, and wherein the actuating element is configured as a push/pull element which is mounted in the shaft.
