Abstract

In order to achieve high rotational speeds for a drive motor used for surgical purposes without the need for excessive maintenance of this motor, it is proposed that it be in the form of a compressed-fluid-driven, gear-type motor having interengaging gears which are sealed in a housing and have a rotational speed of between 40,000 and 150,000 revolutions per minute.
