Abstract: A surgical power tool assembly is provided. The assembly includes a handpiece and a pin driver attachment coupled to the handpiece. The handpiece includes a motor and a controller for operating the motor. A trigger is movably coupled to a housing of the handpiece. The controller controls a speed of the motor based on an actuated position of the trigger. An output drive is coupled to the motor and is rotated by the motor about an axis. An actuation surface of the trigger is moveable relative to the housing such that the actuation surface is closer to the axis in the actuated position than in the unactuated position. The pin driver attachment includes a housing for coupling to the handpiece. The pin driver attachment may include a lever to clamp a surgical pin to drive the surgical pin into bone.

Abstract: A pin driver attachment system is provided. The system includes an input shaft to be coupled to a handpiece housing including a motor. The input shaft receives torque from the motor. The input shaft has a first drive portion having a first bore for connecting to a first surgical pin having a first diameter and a second drive portion having a second bore for connecting to a second surgical pin having a second diameter. The first bore is coaxial with and smaller than the second bore. First and second flexible couplers are secured to the input shaft and associated with the first and second bores. Each coupler has an annular shape and is movable between an engaged position and an unengaged position to secure and release the respective surgical pin to the respective bore. The first coupler has a smaller cross-sectional area than the second coupler.

Abstract: Fuel fill apparatus for use with fluid delivery systems are described. An example fuel fill apparatus includes a body defining a throat area adjacent an opening of the body where the opening is configured to receive a fuel cap. A fuel fill portion defines a first passageway extending at a non-perpendicular angle relative to a longitudinal axis of the opening and a vent portion defines a second passageway. The first passageway is fluidly coupled to the second passageway via the throat area and a fuel nozzle retainer is disposed within the throat area.
