Abstract
A syringe-like bone clamp installation tool has a hollow piston with a longitudinal slot. A shank end of a Reese clamp and at least one of a plurality of right truncated cones of a central portion thereof are disposed within the piston. The piston is slidably disposed within a hollow barrel that has a proximal end from which a forked tab extends through the slot into the piston. The tines of the fork maintain the cone against motion relative to the barrel. An open end is the piston is countersunk to receive a button of the clamp exterior to the piston. As the barrel is moved towards the closed end of the piston, the button is advanced.
