Abstract
This application is directed to a medical instrument with a hollow shaft, an actuating unit at the proximal end and an instrument tip with an instrument at the distal end, wherein the instrument can be actuated via an actuating element in the shaft, the element being in an connection with the actuating unit and the instrument tip being pivotable via a joint mechanism, the joint mechanism having pivoting members connected with a proximal-side drive via steering wires running in the direction of the shaft in such a way that movement of the proximal-side drive causes a corresponding movement of the distal-side pivoting members and a pivoting of the instrument tip and wherein the proximal-side drive includes a spatially adjustable disk on which the steering wires are mounted. In order that the steering wires may be controlled precisely and reproducibly, the drive for the spatially adjustable disk is a motorized drive.
