Method and apparatus for heat tipping sutures

摘要

A heat tipping method and apparatus for surgical sutures to facilitate inserting the sutures into the barrel ends of surgical needles. The method comprises tensioning the suture, heating a portion of the suture to be heat tipped by blowing a current of hot air across the portion of the suture, and releasing the tension and cutting the portion of the suture to create heat tipped ends. The apparatus comprises a cylindrical drum around which the suture is wound, a concave channel in the drum for delimiting a portion of the suture to be heated, and hot air blowers for heating the delimited portions of the suture to a heat tipping temperature.
