Abstract
A suture anchor system including an anchor, a plug and an inserter. The anchor inserter includes a tubular outer shaft having a cannulation dimensioned to receive an inner shaft. The distal end of the outer shaft cannulation is threaded for engagement with the plug. The anchor includes a longitudinal cannulation formed within the anchor body, including a smooth-sided portion and a threaded portion. An eyelet, dimensioned to receive a suture therein, extends transverse to the longitudinal axis of the anchor and intersects the distal portion of the cannulation. The plug is a generally elongated, tubular threaded rod comprising a cannulation adapted to receive a distal end of the inner inserter shaft.
Claims20
A suture anchor system, comprising:
- an inserter including a shaft with a cannulated distal end, the cannulated distal end including a threaded portion;
- and
- an anchor, comprising:
- an eyelet, extending transversely through a longitudinal axis of the anchor dimensioned to receive one or more sutures;
- a cannulation extending along the longitudinal axis of the anchor, the cannulation including a threaded portion;
- and
- a plug having a threaded external surface that threadingly couples directly to both the shaft threaded portion and anchor cannulation threaded portion, and thereby operatively couples the anchor to the inserter.
A suture anchor system, comprising:
- an inserter including a shaft with an internally threaded cavity at an inserter distal end;
- and
- an anchor, comprising:
- an eyelet, extending transversely through a longitudinal axis of the anchor for receiving one or more sutures therethrough;
- a cannulation extending along the longitudinal axis of the anchor, the cannulation including a threaded portion;
- and
- a threaded plug configured to threadingly couple the anchor to the inserter internally threaded cavity and wherein the plug is also configured to advance axially along the anchor cannulation to both threadingly disengage the anchor from the inserter and at least partially secure the one or more sutures within the eyelet.
A suture anchor system, comprising:
- an inserter including a shaft with a cannulated distal end, the cannulated distal end including a threaded portion for selectively threadingly coupling directly with threads of an anchor plug;
- and
- an anchor, comprising:
- an eyelet, extending transversely through a longitudinal axis of the anchor dimensioned to receive one or more sutures;
- a cannulation extending along the longitudinal axis of the anchor, the cannulation including a threaded portion for threadingly coupling to the anchor plug threads.
