A medical instrument with a shaft, a handle positioned on the proximal end of the shaft, a tool positioned on the distal end of the shaft with two jaw members that can be displaced between an open and a closed position, and with an actuating element by which the handle and tool are in active connection with one another and where each jaw member of the tool consists of an inner cheek and an outer cheek, which are connected with one another on the distal end of each jaw member and are distanced from one another in the proximal direction, and at least one connecting brace is positioned between the inner cheek and the outer cheek. The medical instrument has jaw members, while preserving flexibility, have an increased dimensional stability, in particular with respect to torsion impact. The inner cheek and the outer cheek of each jaw member is configured differently with respect to the shape of their cross-section, with the inner cheek configured as wider than the outer cheek and with the inner cheek of each jaw member having rounded or stepped configuration.
A medical instrument, in particular for endoscopic purposes, with a shaft, a handle positioned on the proximal end of the shaft, a tool positioned on the distal end of the shaft with two jaw members that can be displaced between an open and a closed position, as well as with an actuating element by which the handle and the tool are in active connection with one another and where every jaw member of the tool is configured as a jaw member that can be deformed under force impact and that consists of an inner cheek and an outer cheek, which are connected with one another on the distal end of every jaw member and are at a distance from one another in the proximal direction, so that at least one connecting brace is positioned between the inner cheek and the outer cheek, wherein the inner cheek and the outer cheek of each jaw member are configured differently with respect to the 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.
