Abstract

A surgical clip has projections on its load-bearing portion. Also, a forceps used with the surgical clip is formed with depressions or small holes to receive the projections on the surgical clip.

Claims

1. Forceps for holding a surgical clip provided with projections thereon, said forceps comprising:

a guide tube having a longitudinal axis;

a pair of control levers connected to one end of the guide tube so as to be movable toward and away from each other;

a pair of links connected at one end to the pair of control levers;

knee means, connected to opposite ends of the pair of links, for joining the pair of links together;

a wire rod extending through the guide tube and having one end connected to the knee means;

a movable clamping piece being connected to an opposite end of the wire rod and projecting from an opposite end of the guide tube;

a fixed clamping piece provided on the opposite end of the guide tube in parallel with the movable clamping piece; and

bore means, provided in alignment with each other in the movable clamping piece and in the fixed clamping piece in a direction parallel with the longitudinal axis of the guide tube, for receiving projections provided on a surgical clip;

whereby the surgical clip is clamped in a direction perpendicular to the longitudinal axis of the guide tube.
