Expanding suture anchor having an actuator pin

摘要

A method and apparatus for reattaching soft tissue to a boney structure using an expanding suture anchor. The method can include providing a suture anchor and forming a cavity in the boney structure for receipt of the suture anchor. The method can also include coupling the soft tissue to a suture and coupling the suture to the suture anchor. The method can further include deploying the suture anchor to fix the suture to the suture anchor and the suture anchor to the cavity.

1. A method for attaching a soft tissue to a boney structure comprising:
forming a cavity in a boney structure; passing a suture having first and second ends through a soft tissue; passing the first and second ends of the suture into a suture-receiving opening of an insert of a suture anchor; inserting the suture anchor into the cavity; applying a retractive force on the insert through a sleeve of the suture anchor; pivoting an expanding element of the sleeve with the insert, the expanding element defined by a U-shaped slot formed in a midsection of the sleeve so as to be spaced apart from a proximal end and a distal end of the sleeve and surrounded by the sleeve, the U-shaped slot defining three sides of a periphery of the expanding element, with a fourth side of the periphery of the expanding element hingeably coupled to the midsection of the sleeve; and anchoring first and second portions of the suture in contact with a wall of the cavity and the sleeve of the suture anchor without a knot.
