Abstract

One exemplary embodiment relates to an input unit (10) for operating a medical instrument (12) with a hollow shaft (14) extending along a longitudinal axis (L) for receiving guide wires (20), with a tool (16) arranged on the distal side of the shaft (14), extending along an extension axis (E) and a control unit (18) arranged proximally on the shaft (14) for handling the tool (16) by means of the guide wires (20), comprising first input means (22) for continuous, pivoting and rotation-true, preferably uninterrupted and/or absolute, conversion of an ergonomically limited user input, in particular a natural user movement of movable first operating means, into an adjustment movement of the tool (16) in a first handling mode, in order to pivot the tool (16) by means of the control unit (18) relative to the longitudinal axis (L) in a limited way and/or to rotate about the extension axis (E) in a limited way.
