Abstract
A surgical tool incorporates a suture guide with an anchor driver supporting an anchor where the anchor is maintained at a distance from the suture guide until release of a detent mechanism. Thereafter, the anchor is allowed to move into proximity to the suture guide, fixing a suture supported by the suture guide to a substrate, the entire procedure being achievable with a single hand.
Claims20
An implant insertion system comprising:
- a first cannulated shaft having a first longitudinal axis;
- a second shaft disposed coaxially within said first cannulated shaft, said second shaft having a proximal end and a distal end;
- and
- a suture loop feature, said suture loop feature being disposed at said distal end of said second longitudinal shaft, said suture loop feature including a body portion having at least first and second surface regions, said first and second surface regions tapering towards said second longitudinal axis in proximity to a distal end of said suture loop feature, said suture loop feature including a first circumferential edge, a second circumferential edge, and an internal surface region disposed within said first circumferential edge and said second circumferential edge, said internal surface region defining an eyelet of said suture loop feature through said body portion and generally transverse to said longitudinal axis, said body portion including a spine portion disposed adjacent to a first region of said eyelet and a latch portion disposed adjacent to a second region of said eyelet, wherein said latch portion is adapted to flex to transition from a first state in which said eyelet is closed to a second state in which said eyelet is open whereby, in said first state, said eyelet is adapted to capture a length of suture slidingly therewithin and whereby, in said second state, said eyelet is adapted to release said length of suture from said eyelet after said length of suture is disposed within a bone.

An implant insertion system comprising:
- an implant insertion shaft having a proximal end, a distal end and a longitudinal axis disposed between said proximal end and said distal end;
- and
- a suture loop feature, said suture loop feature being disposed at said distal end of said longitudinal shaft, said suture loop feature including a body portion having at least first and second external surface regions, said first and second external surface regions tapering towards said longitudinal axis in proximity to a distal end of said suture loop feature, said suture loop feature including an internal surface region defining an aperture of said suture loop feature through said body portion and generally transverse to said longitudinal axis, said body portion including a spine portion disposed adjacent to a first region of said aperture and a latch portion disposed adjacent to a second region of said aperture, wherein said latch portion is adapted to flex to transition from a first state in which said aperture is closed to a second state in which said aperture is open whereby, in said first state, said aperture is adapted to have a length of suture captured slidingly therewithin and whereby, in said second state, said aperture is adapted to release said length of suture from said aperture after said length of suture is disposed within a substrate.
A method of preparing an implant insertion system comprising:
- providing a shaft, said shaft having a proximal end, a distal end, and a longitudinal axis;
- disposing a spine portion of a suture loop feature proximate to said distal end of said shaft, said spine portion of said suture loop feature having a first proximal end, a second distal end and a first surface region;
- disposing a latch portion of said suture loop feature proximate to said distal end of said shaft, said latch portion of said suture loop feature having a third proximal end, a fourth distal end and a second surface region, said third proximal end being connected to said spine portion of said suture loop feature at said first proximal end of said spine portion;
- and
- disposing said fourth distal end of said latch portion in contact with said spine portion such that said first surface region is disposed in spaced relation to said second surface region across said longitudinal axis, and such that said contact between said fourth distal end of said latch portion and said spine portion tends to retain a suture between said first surface region and said second surface region.
