This invention is a one-piece (150) or two-piece (66, 68) knotless suture anchor assembly for the attachment or reattachment or repair of tissue to a bone mass. The assembly allows for an endoscopic or open surgical procedure to take place without the requirement of tying a knot for reattachment of tissue to bone mass. In one embodiment, a spike member (158) is inserted through tissue and then inserted into a bone mass. The spike member is securely fastened or attached to the anchoring sleeve (66) with a ratchet mechanism thereby pulling or adhering the tissue to the bone mass.

L'invention porte sur un dispositif d'ancrage pour suture sans noeud une pièce (150) ou deux pièces (66, 68) servant à fixer ou à refixer un tissu à une masse osseuse, ou bien à le réparer. Le dispositif permet d'exécuter une intervention endoscopique ou chirurgicale ouverte sans avoir besoin de faire un noeud pour refixer des tissus à une masse osseuse. Dans un modèle, un perforateur (158) est inséré dans les tissus, puis dans une masse osseuse. Il est attaché ou fixé solidement à la gaine d'ancrage (66) au moyen d'un mécanisme d'encliquetage, tirant ou collant ainsi le tissu à la masse osseuse.
