Original Abstract Submitted
A surgical drill system for drilling a bore in a bone. The system has a handpiece including a motor and a chuck coupled to the motor for releasably holding a drill bit to the motor so the drill bit can be rotated by the motor. The handpiece defines a lumen. The system also includes a telescoping member being coupled to the handpiece such that the telescoping member is slidable within the lumen of the handpiece. A spring biases the telescoping member in a distal direction relative to the motor. A brake is attached to the handpiece and is moveable relative to the telescoping member to an engaged position to stop movement of the telescoping member. An actuator is configured to move the brake to the engaged position responsive to a signal received from a controller when the drill bit penetrates bone.
