Abstract
Different mechanical drive devices for a medical, dental or surgical tool are described that are designed to put the tool into an oscillating, rotational motion, wherein the oscillating, rotational motion comprises an alternating rotation of the tool by a first angle of rotation in a first rotational direction and by a second angle of rotation in a second rotational direction substantially opposed to the first rotational direction, wherein the first and second angles of rotation may have different values, so that during multiple sequential rotations in the first and second rotational directions, the tool cumulatively experiences a rotational motion in a preferred direction.
