Abstract: The invention is a super elastic bone plate and inserter. The bone plate has a plate section with openings for screws at fixed or variable angles, an optional compression slot, and a pronged section (i.e. the claw foot), which is generally transverse to the long axis of the plate for insertion, and after deployment returns to an angle of less than 90° to impart compression at a bone/bone interface, e.g. to cause fusion between bone segments. The inserter, which has a first leg with a frictional fit holding block for the plate and a second leg with a holding and activation mechanism for the super elastic pronged section. The invention also relates to a method of bone fusion using the plate system.

Abstract: The invention is an inserter for a staple having a bridge member and opposing open legs and the inserter holds the staple between a pair of cylindrical expanders which splay apart in response to a camming mechanism having a pair of followers that carry the expanders. The followers are activated as they are drawn over the camming ramp in response to a trigger action. The ramp also includes a detent which alerts the user that the staple is engaged in an activated position, and a safety that keeps the followers from returning to the un-loaded position.

Abstract: An assistance device for assisting in operation of an injection syringe including a syringe body carrying an injection needle covered with a protective cap. The assistance device includes a support for housing the syringe body, and a removal device for removing the protective cap, having a gripping member to be maneuvered by a user to remove this protective cap from the injection needle, and at least one extractor cooperating with the protective cap during removal of the protective cap. The removal device also has complementary members for controlling the extractor, which can be moved relative to each other in a relative engagement movement, to move the extractor between a reference configuration retracted relative to the protective cap and a cooperation configuration cooperating with the protective cap. The relative engagement movement is independent of the maneuvering movement applied by the user to the gripping member to remove the protective cap.

Abstract: The present disclosure relates to improved plate and screw systems for use in fusion and other surgical procedures, which improve the ability to effectively affix adjacent bodies without gapping or experiencing loss of compression over time. The systems include plates having armatures configured to receive bushings, the bushings configured to pivot and rotate and thereby permit a greater degree of orientation of corresponding screws placed through the bushings. In embodiments, the bushings comprise anti-rotation elements which lock the bushings in a desired orientation. Methods for use of the components described herein are also disclosed.
