    摘要: 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 article 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.

    摘要: An automatic pull-testing apparatus for testing the strength of an armed surgical needle comprises a supporting blade for supporting a suture receiving end of the armed needle and having at least one suture receiving guide therein. A first gripping device is provided for releasably retaining the armed needle in an oriented position, and for positioning the armed needle at the supporting blade to enable the suture strand depending therefrom to be threaded at the suture receiving guide. A second suture gripping device grips the suture at a position below the suture receiving guide of the supporting blade. A slide block counterweighted to a predetermined weight is connected to the second suture gripping device for applying a controlled positive downward force upon the suture strand. When the first gripping device releases its grip upon the armed needle and the second gripping device and the slide block is released, a positive downward force is applied to the suture strand to perform a minimum pull-test of the armed needle. A destructive pull test is also performed by a device that generates a positive force against the slide block that is sufficient to dislodge the suture from the needle.
