  • Plastic ligating clips
    Patent number: 4446865
    Abstract: Plastic ligating clips of absorbable or nonabsorbable materials are formed by two legs joined with a resilient hinge. One leg terminates in a hook member which secures the other leg when the clip is closed. Each leg of the clip is provided with an indentation extending across its width near the distal end which secures the clip in the applier and allows the clip to rotate about its hinge during closure. The clip applier is a forceps-type instrument having channeled jaws especially adapted to receive and close the plastic clip.
