Abstract
In at least one aspect of this disclosure, a surgical drill can include a housing, a retracting enclosure slidably disposed within the housing and configured to move between an extended position and a retracted position and a retracting motor operatively connected to the retracting enclosure to move the retracting enclosure between the extended position and the retracted position. The drill can further include a drill motor including a motor shaft configured to connect to a drill chuck and disposed within the retracting enclosure such that the motor shaft can rotate relative to the retracting enclosure.
Claims12
A surgical drill, comprising:
- a housing;
- a retracting enclosure slidably disposed within the housing and configured to move between an extended position and a retracted position;
- a retracting motor operatively connected to the retracting enclosure to move the retracting enclosure between the extended position and the retracted position;
- a drill motor including a motor shaft configured to connect to a drill chuck and disposed within the retracting enclosure such that the motor shaft can rotate relative to the retracting enclosure;
- a trigger switch configured to allow electrical energy to selectively flow to the retracting motor or the drill motor;
- a forward drill trigger operatively connected to the trigger switch;
- a reverse drill trigger operatively connected to the trigger switch, wherein the trigger switch is configured to activate the drill motor in a first rotational direction when only the forward drill trigger is actuated,
- wherein the trigger switch is configured to activate the drill motor in a reverse direction relative to the first rotational direction when only the reverse drill trigger is actuated,
- wherein when both the forward drill trigger and the reverse drill trigger are actuated simultaneously, the trigger switch is configured to actuate the retracting motor to move the retracting enclosure from the extended position to the retracted position.
