A surgical instrument and a bearing arrangement includes a wobble plate having a main shaft. The wobble plate is rotatable about two axes and to the main axes of the main shaft. An intersection of the two axes defines a pivot center of the wobble plate and is located on the main axis. The main shaft has a spherical coupling portion. The wobble plate includes a hollow spherical outer bearing opening. A bearing arrangement includes rolling bearing balls and a ball cage movably arranged in the outer bearing opening and delimits a hollow spherical inner bearing opening. The ball cage includes window openings in which the rolling bearing balls are arranged. The coupling portion has first round grooves for the rolling bearing balls and the outer bearing opening has second round grooves for the rolling bearing balls.

Wobble plate bearing arrangement and surgical instrument equipped therewith

One exemplary embodiment relates to an input unit () for operating a medical instrument () with a hollow shaft () extending along a longitudinal axis (L) for receiving guide wires (), with a tool () arranged on the distal side of the shaft (), extending along an extension axis (E) and a control unit () arranged proximally on the shaft () for handling the tool () by means of the guide wires (), comprising first input means () 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 () in a first handling mode, in order to pivot the tool () by means of the control unit () relative to the longitudinal axis (L) in a limited way and/or to rotate about the extension axis (E) in a limited way.
