Coupling for a surgical rotary drive hand piece comprises a catch which slides against the action of a spring into a extended position using a tool

摘要

Coupling comprises a catch (10) which slides against the action of a spring (13) into a extended position using a tool (23). The shaft (24) of the tool extends into a receiver (7) whose bearing surfaces lie on the bearing surfaces of the tool forming a rotary slave. An independent claim is also included for a tool used in the coupling. Preferred Features: The bearing surfaces of the catch and tool lie flat on each other. Both bearing surfaces of the catch and/or the tool are arranged in a V-like manner.
