Knotless suture anchor and method of using same

摘要

A suture anchor including a first portion and a second portion. The first portion defining a first suture bore and having an angled distal surface that extends in a plane oblique to a longitudinal axis of the suture anchor. The second portion defining a second suture bore and having an angled proximal surface that is complementary to the angled distal surface. The angled proximate surface extends in a plane oblique to the longitudinal axis. In a first configuration, the first portion and the second portion are aligned along the longitudinal axis, and the first suture bore is aligned with the second suture bore. In a second configuration, the first portion and the second portion are offset with respect to the longitudinal axis, and the first suture bore is offset from the second suture bore to retain a suture within the first suture bore and the second suture bore.

1. A method of knotlessly securing a suture to a suture anchor comprising:
implanting the suture anchor in a bone hole with an insertion tool, the suture anchor including a first portion defining a first suture bore and a second portion defining a second suture bore, the suture extending through the first and the second suture bores; moving the second portion of the suture anchor relative to the first portion of the suture anchor using the insertion tool to misalign the first portion and the second portion, and to misalign the first and the second suture bores to pinch the suture between the first and second portions to retain and restrict movement of the suture within the first and the second suture bores along a longitudinal axis of the suture anchor; and actuating a deployment shaft of the insertion tool to move the second portion of the suture anchor toward a distal end of a cannula to which the suture anchor is mounted.
