Abstract

A surgical stapler having a trigger attached to a ratcheting mechanism for preventing the refiring of the stapler trigger with a staple loaded within a forming mechanism. In addition, the mechanism contains driver buffering means to prevent the sharp reduction in opposing force driving formation of a staple. The staples 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 do not hinder forming.
