Cerclage suture tensioner and methods of tensioning
A surgical tensioner and methods for surgical repairs. A tensioner can tension a flexible strand (suture or wire) attached to tissue (for example, graft or bone segments). A tensioner can include an angled tip with a split hole to past-point on a knot and lock the construct during tensioning. A tensioner can include a securing mechanism that can capture a flexible strand and lock it into place.
1. A tensioner for tensioning limbs of a flexible strand secured to tissue, comprising:
a body having a longitudinal axis, a distal end, and a proximal end; and
a tip at the distal end of the body, the tip having a first through-passage and a second through-passage to receive the flexible strand and to allow a first limb of the flexible strand to pass through the first through-passage and a second limb of the flexible strand to pass through the second through-passage.
2. The tensioner of claim 1 , further comprising a handle assembly at the proximal end of the body configured to secure and tension the first limb and the second limb.
3. The tensioner of claim 1 , wherein the tip is an angled tip with a most distal end surface that forms an angle other than about 90 degrees with the longitudinal axis of the body.
4. The tensioner of claim 1 , wherein the flexible strand is suture and the tip includes two suture passages.
5. The tensioner of claim 4 , wherein the two suture passages are parallel to each other.
6. The tensioner of claim 4 , wherein the two suture passages are non-parallel.
7. The tensioner of claim 1 , wherein the handle includes a thumb pad with a plurality of cleats to secure the first limb and the second limb.
8. The tensioner of claim 1 , wherein the tip is rotatable relative to the body.
9. The tensioner of claim 1 , wherein the tip is stationary and integral with the body.
10. The tensioner of claim 1 further comprising a spring, a tubular member, and a shaft, wherein the spring and at least a portion of the tubular member and at least a portion of the shaft are housed within the body.
11. The tensioner of claim 1 , wherein the first limb and the second limb are sutures, tapes, wires, or cables.
