Abstract: An impact tool includes a controller configured to control power being delivered to the and operable in one of: (a) a normal mode where the controller allows power to be delivered to the motor so that the impact mechanism transitions from operation in the rotary mode to operation in the impacting mode when an output torque exceeds a normal transition torque; and (b) a control mode where the controller controls power being delivered to the motor so that the impact mechanism transitions from operation in the rotary mode to operation in the impacting mode when an output torque exceeds a control transition torque that is greater than the normal transition torque.

Abstract: A two-part screw system includes an inner member and a cannulated outer member that may be pre-assembled with an inner member driver and an outer member driver to form a surgical assembly. A method of inserting the two-part screw system includes advancing the inner member into the bone by using the inner member driver, and advancing the outer member into the bone by using the outer member driver. The inner member acts as a guide for the outer member, and eliminates the need for a separate guide wire. The pre-assembled nature of the surgical assembly eliminates the need to sequentially remove and apply drivers and implant parts. The inner member and the outer member are configured to integrate into a substantially solid body when in a final alignment, thus forming a stronger implant than a cannulated screw.

Abstract: A power tool includes a housing, a motor disposed in the housing, an output spindle configured to be driven by the motor, an input switch, and a controller configured to control power being delivered to the motor. The controller is operable in one of: (a) a normal mode where the controller causes continuous electric power to be delivered to the motor during actuation of the input switch in a first range of positions; and (b) a feathering mode where the controller causes discontinuous electric power to be delivered to the motor during actuation of the input switch in a second range of positions that is different from the first range of positions motor to simulate feathering the input switch.
