The present disclosure provides staples, and corresponding staple guides, for applying a compressive force between biological elements. The staples may include a bridge portion and a pair of tines extending from the bridge portion configured for implantation into biological elements. The tines may be spaced a first distance in a first state of the bridge portion. The bridge portion may be elastically deformable into a second state with the pair of tines spaced a second distance that is greater than the first distance and the tines pre-loaded to apply a compressive force therebetween. The guides may include a staple engagement portion operable to maintain the biased state of the staple, and/or a drill guide portion operable to facilitate the formation of apertures spaced the second distance in the biological elements.

Staples and staple delivery and drill guides

An impactor having a housing including an upper portion and a lower portion at least a part of which extends perpendicularly from the upper portion, a ram having a first end positioned in the upper portion and positioned in axial alignment with the lower portion, an opposite end of the ram extending from the lower portion of the housing, at least one drive assembly including a first drive shaft operably coupled to a cam shaft, a cam operably coupled to the cam shaft, a cam operably coupled to the cam shaft, the drive shaft operably connectable to motor, wherein the cam is operable to rotate and positioned to contact the proximal end of the ram upon rotation of the cam, a circuit board comprising circuitry operable to receive instructions from a plurality of switches electrically coupled to the circuit board to operate the impactor, wherein the impactor is operable to deliver low amplitude pulsed strikes to a workpiece at variable frequencies.
