ABSTRACT:
A stapler for interconnecting adjacent penetrable bodies such as vertebrae includes a barrel with a staple support and deforming anvil at one end thereof; a plunger slidably mounted in the barrel for pressing the staple against the anvil to deform and drive the staple out of the stapler into the vertebrae; a handle and trigger at the other end of the handle for driving the plunger against the anvil and out of the stapler; a helical spring for returning the plunger to the rest position; and a control sleeve and pin arrangement for placing the plunger in the "DISMANTLE", "LOAD", "SAFE" or "FIRE" position, in which the stapler can be dismantled or assembled, loaded, inserted into position or fired.
