ABSTRACT:
A surgical stapler device of the so-called pistol grip type includes a stack of staples loaded into a lower cartridge in an orientation similar to a conventional paper stapler. A former rotates and turns a leading staple 90.degree. or normal to its prior orientation in the stack of staples as the former slides between a start position and an intermediate position. The rotational movement of the staple insures maximum clarity in the surgeon's line of visions when placing a staple in position. The former is further displaced between an intermediate and a final position wherein the staple is formed around a staple forming surface of an anvil. The former also cams the anvil downwardly separating the formed staple from the anvil lip, thereby allowing the former to receive a staple from the stack of staples onto its staple transport surface for sequential stapling.
