Tissue fixator
The present disclosure relates to a needle for attaching a fixator to a soft tissue graft. The needle includes a pointed distal end and a proximal end, the proximal end including a suture coupler, the suture coupler including a hook and a pocket formed by the hook, wherein the needle is curved along an entire length of the needle. A fixator for use with the needle and method of fixating a soft tissue graft to a bone is also disclosed.
1. An assembly comprising:
a flexible member;
a needle having a pointed distal end, a proximal end of the needle including a hook to which a first end of the flexible member is attached;
a fixation device to which a second end of the flexible member is attached, a lengthwise axis of the fixation device oriented orthogonal with respect to a segment of the flexible member;
wherein the flexible member passes through a hole at a first location of a penetrable element, the penetrable element being synthetic tissue;
wherein the flexible member passes through a hole at a second location of the penetrable element, the hole at the second location disposed further from a distal end of the penetrable element than the hole at the first location;
wherein a first portion of strands of the flexible member is disposed side-by-side, the first portion of strands passing through the hole at the first location of the penetrable element;
wherein a second portion of strands of the flexible member is disposed side-by-side, the second portion of strands passing through the hole at the second location of the penetrable element;
wherein the strands of the flexible member includes a first strand and a second strand;
wherein a portion of the penetrable element resides between a portion of the first strand and the second strand of the flexible member extending between the hole at the first location and the hole at the second location; and
wherein the penetrable element resides between a separation of the strands of the flexible member extending between the hole at the second location of the penetrable element and the first end of the flexible member attached to the proximal end of the needle.
2. The assembly as in claim 1 , wherein the needle is curved.
3. The assembly as in claim 2 further comprising:
a trailing suture;
a leading suture;
wherein the hook defines a pocket, an opening to the pocket located on a convex side of the curved needle;
wherein the trailing suture is coupled to the first hole in the fixation device; and
wherein the leading suture is coupled to the second hole in the fixation device.
4. The assembly as in claim 2 further comprising:
a first suture;
a second suture;
wherein the first suture is secured to the first hole in the fixation device; and
wherein the second suture is secured to the second hole in the fixation device.
5. The assembly as in claim 1 , wherein the flexible member is a continuous loop of flexible material.
6. The assembly as in claim 1 , wherein a first end of the flexible member is attached to the proximal end of the needle; and
wherein a second end of the flexible member is attached to the fixation device.
7. The assembly as in claim 1 , wherein the separation of the strands of the flexible member is tensioned around the penetrable element.
8. The assembly as in claim 7 , wherein the flexible member is a loop suture.
