DRIVE DEVICE FOR A MEDICAL TOOL, IN PARTICULAR FOR A DENTAL OR SURGICAL TOOL

摘要

The invention describes various mechanical drive devices (1, 1A), mechanical gears (4, 29, 30), combinations thereof, and a medical treatment device, in particular a dental or surgical treatment device (14, 25, 25A), having such mechanical drive devices (1, 1A) or gears (4, 29, 30), by which a unidirectional rotating motion received from a motorized drive is converted into a multi-directional motion, such that a tool holder (23) of the treatment device (14, 25, 25A) can be moved in a multi-directional motion, particularly in a preferably simultaneous reciprocating and rotating motion or reciprocating and oscillating rotational motion with reduced speed.
