Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
A ligating clip applying instrument comprising a pair of handles pivoted about a hinge point and extending beyond the hinge point to form a pair of clip closing jaws having opposing inner faces, each of said jaws having a recessed clip-receiving channel in the inner face thereof extending from the forward tip of said jaw rearward toward said hinge point, said channel having a length at least equal to the length of the clip to be applied by said instrument, each channel having an abutment across the base thereof spaced from the tip of said jaw, said abutment being a raised area extending across the width of the jaw and having a generally convex semi-cylindrical shape with the axis of the cylinder extending across said jaw, the depth of the channel forward of said abutment being greater than to the rear of said abutment.
Claim 2
Dependent Claim
144 words
A ligating clip applying instrument comprising a pair of handles pivoted about a hinge point and extending beyond the hinge point to form a pair of clip closing jaws having opposing inner faces, each of said jaws having a recessed clip-receiving channel in the inner face thereof extending from the forward tip of said jaw rearward toward said hinge point, said channel having a length at least equal to the length of the clip to be applied by said instrument, each channel having an abutment across the base thereof spaced from the tip of said jaw, said abutment being a raised area extending across the width of the jaw and having a generally convex semi-cylindrical shape with the axis of the cylinder extending across said jaw, the depth of the channel forward of said abutment being greater than to the rear of said abutment.
Claim 3
Dependent Claim
31 words
The instrument of claim 1 wherein the abutments in each channel are in opposed alignment relative to the inner faces of said jaws when said jaws are in a closed position.
