SURGICAL CLIP
This surgical clip ( 1 ), comprises, on at least one lateral arm ( 3 ), several successive projecting portions ( 4 ), particularly of a tapered shape, forming series of shoulders ( 5 ) suitable for opposing, after insertion, the extraction of said lateral arm ( 3 ) from the bone. According to the invention, at least one projecting portion ( 4 ) of said lateral arm ( 3 ) comprises at least one groove ( 6 ) opening onto the shoulder ( 5 ) formed by said portion ( 4 ), said groove ( 6 ) and said shoulder ( 5 ) thus delimiting a pointed and sharp material zone ( 7 ), suitable for hollowing the bone when, after the intermediate arm ( 2 ) of the clip has been cut, said lateral arm ( 3 ) is driven in rotation.
1 . A surgical clip comprising:
at least on lateral arm for insertion into bone comprising several successive projecting portions forming a series of shoulders suitable for opposing the extraction of said at least one lateral arm from bone, wherein at least one said projecting portions comprises at least one groove opening onto at least one of the shoulders, said at least one groove and said at least one shoulder delimiting a pointed and sharp material zone suitable for hollowing the bone when, after the intermediate arm of the clip has been cut, said at least one lateral arm is rotated.
2 . A surgical clip according to claim 1 , wherein each of said successive projecting portions displays a tapered shape.
3 . A surgical clip according to claim 1 wherein said at least one groove has a triangular cross-section.
