1. An input unit configured to operate a medical instrument with a hollow shaft extending along a longitudinal axis and configured to receive 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 relative to the longitudinal axis by the control unit and/or to rotate it to a limited extent 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 its extension axis in a second handling mode, wherein the first input means are configured as operating means that can be moved in a first actuating section and the second input means are configured as switching means for switching the user input of the operating means limited by the switching means between the first and the second handling mode, wherein the switching means can be switched by reaching and/or exceeding a force and/or torque on the operating means.
