Abstract
A surgical drill for use with a drill bit. The drill includes a handpiece with a motor and a brake mechanism. The brake mechanism is a sliding rack adjacent a first end and a second end with a stop adjacent the drill bit. An actuator is mounted to the handpiece and a plunger is coupled to the actuator. A sensor asserts a signal when the drill bit penetrates bone. When the sensor asserts the signal indicting the drill bit penetrated bone, the actuator moves the plunger into engagement with the rack to prevent further insertion of the drill bit.
