ABSTRACT:
An apparatus for cutting an indefinite length suture strand to uniform lengths for subsequent threading and swaging to a surgical needle includes a drawing tower having at least one guide member defining a drawing axis parallel thereto. First and second gripping devices are provided to grip the indefinite length suture strand and draw it along the drawing axis; each gripping device mounted for reciprocal movement on at least one guide member. A retractable cutter for cutting the indefinite length suture strand is also provided for cutting the strand at a start position along the drawing axis. The indefinite length suture strand is fed to the drawing axis and drawn a predetermined distance beyond the location of the retractable cutter for positioning within a suture receiving opening formed in the surgical needle, while the second gripping device reciprocates to a start position along the drawing axis. The indefinite length suture strand is then inserted within the suture receiving opening of the needle and cut to a predetermined length by the retractable cutter after the second gripping means has gripped the indefinite length suture strand at the start position.
