A suture anchor, an insertion tool for inserting a suture anchor, and a device for internal working of hole in bony tissue. The anchor comprises an anchor body having a longitudinal cross-section defined by a perimeter. The perimeter comprises at least one tissue-intruding edge formed between the first side and the second side of the perimeter. The intruding edge is arranged to penetrate the tissue during a rotating motion of the anchor in said opening. The anchor further comprises an abutment surface, arranged substantially on the opposite side of the anchor body in relation to said intruding edge. The first side of the intruding edge is arranged to connect with the abutment surface by a connecting part of the perimeter having the shape of a substantially curved piece in said longitudinal cross-section. |
