Abstract: A compression staple system for bone fixation may include a first drill, configured to create a first hole in a bone, and a drill guide. The drill guide may include a handle, a foot portion coupled to the handle, a first guide sleeve slidably received in the foot portion and including a first aperture configured to guide the first drill towards the bone, and a second guide sleeve slidably received in the foot portion and including a second aperture configured to guide the first drill towards the bone. The first guide sleeve and the second guide sleeve may have a first compression spring configured to bias the first guide sleeve away from the foot portion and towards the bone, and a second compression spring configured to bias the second guide sleeve away from the foot portion and towards the bone.

Abstract: A method for bone fixation using a compression staple system may include loading a compression staple including legs into an inserter, positioning a drill guide proximate first and second bone portions, using the drill guide and a drill to create a first and second hole in the first and second bone portions, wherein the first and second holes may be configured to receive the legs of the staple, using the drill guide and a first and second drill pin, driving the first and second drill pins into the first and second bone portions, withdrawing the drill guide and leaving the drill pins in the first and second bone portions, guiding the inserter and the staple over the first and second drill pins, inserting the legs of the staple into the first and second holes, actuating the inserter to release the staple, withdrawing the inserter, and removing the drill pins.

Abstract: A compression staple system for bone fixation may include a compression staple configured to span first and second bone portions. The staple may apply compression between the first and second bone portions. An inserter may be configured to releasably engage the staple. The inserter may include a stationary jaw including a first retention mechanism and a moveable jaw including a second retention mechanism. The moveable jaw may be moveable between a closed configuration wherein the stationary jaw may be spaced apart from the moveable jaw a first distance, and an open configuration wherein the stationary jaw may be spaced apart from the moveable jaw a second distance greater than the first. The staple may be captive within the inserter in the closed configuration. The staple may be releasable from the inserter in the open configuration, and the stationary and moveable jaws may remain parallel between the close and open configurations.

Abstract: An improved torque control and fluid shut-off mechanism for a fluid operated tool includes a bit holder and driving clutch member which are connected for uniform cojoint axial movement and independent rotary movement. Spring biased ball bearings provides for cojoint rotary movement which is overcome when the spring biasing force associated with the driving clutch member exceeds a threshold level. A locking sleeve fitted over the driving clutch member cooperates with a control rod for the fluid inlet to the rotary vane air motor to control initiation of operation, termination of operation, and resetting of the tool.
