Medical handle with pneumatic safety coupling

A medical handle for a pneumatically or hydraulically driven medical instrument, the medical handle comprising:

• a clutch member on a side of the medical handle for mechanical and pneumatic/hydraulic coupling of a corresponding clutch member on a side of the pneumatically or hydraulically driven medical instrument;
• and
• a manually operable valve mechanism for selective pressurization of the pneumatically or hydraulically driven medical instrument coupled thereto or the motor unit thereof, which medical handle is equipped with a safety function for preventing pressurization when the pneumatically or hydraulically driven medical instrument or a motor unit thereof is uncoupled,
• wherein the clutch member present on the side of the medical handle interacts with the valve mechanism such that during or by a mechanical coupling operation, the valve mechanism is automatically opened or enabled for manual opening, whereas correspondingly in an uncoupled state, the valve mechanism is closed or enabling is correspondingly cancelled,
• wherein the clutch member on the side of the medical handle interacts with a manually operable valve device of the valve mechanism such that the valve device is operative for manual opening and closing only in a state in which the clutch member is coupled and locked and is inoperative in a state in which the clutch member is uncoupled.
