1. An input unit configured for operating a medical instrument having a hollow shaft extending along a longitudinal axis for receiving guide wires, with a tool arranged distally on the shaft and a control unit arranged proximally on the shaft for handling the tool by means of the guide wires, comprising:
first input means for the continuous, pivoting and/or rotation-true conversion of an ergonomically limited user input into an adjustment movement of the tool in a first handling mode in order to pivot the tool to a limit relative to the longitudinal axis by means of the control unit and/or to rotate it to a limit about the extension axis, wherein
the input unit has second input means for at least partially, non-absolutely converting at least one further user input into an endless rotational movement (ωE) of the tool about the tool's extension axis in a second handling mode, wherein the first input means is arranged as a control handle that can be pivoted relative to a rest position with a first rotary element arranged at the control handle for rotation-true rotation of the tool in the first handling mode and the second input means are formed either as at least one second rotary element for controlling the second handling mode or as switching means for switching of the first rotary member between controlling the first and second handling modes.
