Abstract

Various exemplary methods and devices for tensioning grafts are provided. In general, a surgical device can include a grip and a frame. The frame can have two opposed segments. The segments can be spaced apart from one another and can each be configured to have at least one suture attached thereto. The sutures attached to the frame can each be configured to attach to a graft. The two segments can be configured to dynamically move toward and away from each other in response to tension that is applied to the sutures attached to the frame. The frame can include an indicator configured to provide an indication of the tension applied to the sutures. The grip can have at least one opening therein. The at least one opening can be configured to have a surgical instrument passed therethrough.

First claim

What is claimed is:

1. A surgical device, comprising:
a grip configured to be held by a user, the grip including at least one opening formed therein and configured to allow passage of a surgical instrument therethrough;
a frame formed of opposed and diverging first and second segments, the first and second frame segments connected to each other at one end by a first flexure and a second flexure, the grip connected to the first flexure at a first end and connected to the second flexure at a second end, and the first and second frame segments being separated at an opposite end by a variable angle, each of the first and second frame segments having at least one suture retention mechanism formed thereon wherein each suture retention mechanism is configured to removably receive and engage a suture strand; and
a tension indicator operably coupled to at least one of the first and second frame segments and viewable from a position proximal to the grip, the tension indicator being configured to provide a representation of a magnitude of a tension applied to the first and second frame segments to decrease the variable angle, the magnitude of the tension being visible on the indicator.

2. The surgical device of claim 1 , wherein the tension indicator is viewable through the at least one opening.

3. The surgical device of claim 2 , wherein the tension indicator includes a first indicator segment and a second indicator segment configured to facilitate visualization of the indicator regardless of an angular orientation at which the user holds the device.

4. The surgical device of claim 3 , wherein the position of the first indicator segment and the second indicator segment relative to each other provides the indication of the tension applied to the frame.

5. The surgical device of claim 3 , wherein the first indicator segment is one of a top or bottom indicator segment and the second indicator segment is the other of the top or bottom indicator segment.

6. The surgical device of claim 5 , wherein at least one of the top or bottom indicator segments is viewable from a users position.

7. The surgical device of claim 6 , wherein the indicator is configured to indicate any one of a plurality of predetermined tension values.

8. The surgical device of claim 2 , further comprising a plurality of sutures, wherein each of the sutures is configured to be removably secured to one of the suture retention mechanisms.

9. The surgical device of claim 8 , wherein the indicator is configured to provide an indication of the tension applied to the plurality of sutures.
