Abstract

The device comprises a rotationally driven surgical instrument incorporating a hand-held element having a mount rotatably installed therein for reception of interchangeable cutting and milling inserts, a driving motor for driving the mount receiving the tool inserts, a control unit for controlling the driving motor with means of setting the rotational speed and of preselecting the rotational speed range and direction of rotation as well as a digital indicator for displaying the rotational speed set up in each case. For the purpose of accessible storage of setting data, the control unit incorporates a non-volatile read-write memory for digital storage of rotational speeds, a code carrier as well as a coding/decoding arrangement.
