Abstract

A medical handle for pneumatically or hydraulically driven medical instruments or motor units includes a clutch member for mechanical and pneumatic/hydraulic coupling of a corresponding clutch member and a manually operable valve mechanism for selective pressurization of a medical instrument coupled thereto or the motor unit thereof, the valve mechanism being provided with a safety device for preventing pressurization in the case of an uncoupled medical instrument or the motor unit thereof. The clutch member present on the side of the handle is provided to interact with the valve mechanism such that during or by the mechanical coupling operation the latter is automatically opened and/or enabled for manual opening, whereas in the uncoupled state the valve mechanism is closed and/or enabling is cancelled.
