Abstract

A swaging system for attaching surgical needles to sutures and testing the attachment strength includes a bottom swaging die and a top swaging die that is configured to move up and down along a swaging axis that is in alignment with the bottom swaging die. The bottom swaging die includes a swaging tool mounted thereon that extends toward the top swaging die along the swaging axis. The swaging tool includes an upper end having a top surface with a swaging notch for swaging a needle to a suture to form an armed surgical needle, and a testing notch, adjacent the swaging notch, for conducting a pull test on the armed surgical needle.
