Abstract

Surgical drill comprises a pneumatic torque motor, an output device for transmitting motor rotation to a drill, and a fastening or clamping device for fixing the drill to the output device. The fastening device contains transmission means for converting air pressure to a drill clamping force. The transmission pref. contains an air chamber in the output device, and a piston in the chamber for ejection from the chamber by compressed air. Movement of the piston produces a force for pressing the fastening device against the drill. This automatic chuck is thus locked when the motor is a started, and the air used to drive the motor is also used to lock the drill. The drill is retained reliably without jamming on locking.
