A surgical stapler having a trigger (40) attached to a racheting mechanism (28, 36) for preventing the refiring of the stapler trigger (40) with a staple loaded within a forming mechanism. In addition, the mechanism contains driver buffering means (26) to prevent the sharp reduction in opposing force driving formation of a staple (100). The staples (100) are constantly maintained in proper orientation during transfer from a track to the forming site, and are self-centering on the former, and have an oversized crown so that cold-worked areas on each staple (100) do not hinder forming. <IMAGE> |
