Abstract
Abstract A surgical clip for closing the margins of a wound, is disclosed, which clip consists of a bridge and two legs having cutting edges at their ends and projecting from opposite ends of the bridge. Each leg has a part formed as an arc of a circle which adjoins the bridge, and a free ended straight section including the cutting edge of the leg, extending from the arcuate part of the leg. For reducing trama when the clip is implanted and for maintaining eversion of the wound margins after the clip has been implanted, the straight sections of the legs are set at an angle in the range of 2.5° to 10° with respect to the axis of symmetry of the clip.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
A surgical clip having an axis of symmetry and comprising a bridge and two legs extending therefrom, one on each side of said axis of symmetry, each leg having a part extending over an arc of a circle and being connected to, and projecting from, the bridge, from which arcuate part extends a straight free ended section having a cutting edge, wherein each straight section is set at an angle which lies in the range of 2.5° to 10° with respect to said axis of symmetry.
Claim 2
Dependent Claim
86 words
A surgical clip having an axis of symmetry and comprising a bridge and two legs extending therefrom, one on each side of said axis of symmetry, each leg having a part extending over an arc of a circle and being connected to, and projecting from, the bridge, from which arcuate part extends a straight free ended section having a cutting edge, wherein each straight section is set at an angle which lies in the range of 2.5° to 10° with respect to said axis of symmetry.
Claim 3
Dependent Claim

A surgical clip as claimed in claim 1, comprising smooth transitions between the arcuate parts of the legs and the bridge.
Claim 8
Dependent Claim
25 words
A surgical clip as claimed in claim 1, comprising smooth transitions between the arcuate parts of the legs and the straight free ended sections thereof.
Claim 9
Dependent Claim
28 words
A surgical clip as claimed in claim 1, wherein the legs are formed with kinks at transitions between the arcuate parts and said straight sections of the legs.
Claim 10
Dependent Claim
63 words
A surgical clip as claimed in claim 1, wherein the angle over which the arcuate part of each leg extends, as measured between an imaginary perpendicular intersecting the radius point of the arc of such arcuate part and intersecting the bridge, and the junction between such arcuate part and the straight section of said leg lies in the range of 80° to 100°.
