Abstract
Surgical constructs, assemblies and methods for surgical repairs are disclosed. A swivel anchor is employed with a driver provided with a driver-eyelet attachment mechanism that allows a suture eyelet to engage a mating driver shaft. The attachment mechanism includes one or more flexible prongs on the driver tip that are configured to mate with one or more apertures on the eyelet. The prongs are configured to flex in and out of the eyelet apertures. The swivel anchor may be locked and secured within tissue by inserting a cannulated fixation device to abut and contact the eyelet.
Claims24
A driver-eyelet attachment mechanism comprising:
- a driver having a shaft with a longitudinal axis, a proximal end and a distal end, and a plurality of prongs extending away from the distal end and about parallel to the longitudinal axis of the shaft;
- and
- an eyelet with a plurality of apertures configured to securely engage with and disengage from the plurality of prongs of the shaft, and with a suture passage configured to hold at least one flexible strand.
A surgical anchor assembly for tissue repairs, comprising:
- an anchor with a cannulated anchor body and an outer surface having at least one fixation structure for securing the cannulated anchor body in a bone hole;
- and
- an eyelet that is separable from the anchor, wherein the eyelet has an eyelet body with an aperture configured to hold at least one flexible strand, and wherein a most proximal end of the eyelet body contacts and abuts a most distal end of the cannulated anchor body when the surgical assembly is secured within tissue.
A method of implanting a swivel anchor construct with a driver assembly, the swivel anchor construct comprising a fixation device and an eyelet that is separable from the fixation device, wherein the fixation device has an inner surface defining a cannulation, wherein the eyelet has an eyelet body with an aperture configured to hold at least one flexible strand, the driver assembly comprising a driver with a driver shaft terminating in a plurality of prongs, wherein the driver shaft extends through the cannulation of the fixation device so that the fixation device is movable axially relative to the driver shaft, the method comprising:
- inserting the eyelet on the driver shaft;
- and
- flexing the plurality of prongs inwardly while pushing the eyelet on.
