Abstract:
1. A medical instrument with a proximal instrument part and a distal instrument part that are connected with one another by an elongated shaft, such that the distal instrument part includes a pivot element that is mounted to pivot with respect to the shaft and that is pivotable by means of a translationally movable actuation element, wherein the pivot element is coupled with the actuation element by means of at least one coupling element, so that the coupling element is in a hinged connection with the pivot element by a first hinged connection and with the actuation element by a second hinged connection, the second hinged connection of the coupling element is controlled by at least one nonlinear channel or nonlinear groove formed by the distal instrument part in such a way that the pivot element is pivotable both in one pivot direction as well as in the other pivot direction, and the nonlinear channel or nonlinear groove is configured to guide the actuation element in nonlinear movement.
