Suture management and tensioning devices and methods for soft tissue reconstruction or bone-to-bone fixation
An adjustable, stand-alone tensioning system requires no additional fixturing, weights, or bone surface modification, and allows a single practitioner to provide an adjustable and repeatable tension to a soft tissue graft, and to install the final fixation implant. Its design facilitates introduction of the suture component of the graft into the tensioning process by simplifying retention of the suture. An even, regulated and reproducible tension is easily achieved without requiring the practitioner to manually pull on the suture strands to maintain graft tension.
1. A suture management device for use during an orthopedic procedure comprising:
a first body, a center portion and a second body wherein said first body and said second body are each connected to said center portion such that the first and second bodies are symmetric about the center portion and wherein the first body extends away from the center portion longitudinally in a first direction and the second body extends away from the center portion longitudinally in a second direction directly opposed to said first direction, the center portion being C-shaped, each of the first and second bodies further comprising:
a surface disposed on the first and second bodies and structured for resting portions of a patient's body for stabilizing the suture management device relative to a procedural site within the patient's body;
a structure accommodating a length of suture; and
a tensioning apparatus comprising a suture tensioning spring;
wherein the tensioning apparatuses of each of the first and second bodies are disposed, respectively, on each of the first and second bodies, so that the respective suture tensioning springs of each suture tensioning apparatus are aligned longitudinally with one another.
2. The suture management device as recited in claim 1 , wherein the tensioning apparatus in said first body includes a first one of said suture tensioning springs and a first suture tensioning control engaged with said first suture tensioning spring, and the tensioning apparatus in said second body includes a second one of said suture tensioning springs and a second suture tensioning control engaged with said second suture tensioning spring, wherein each of said tensioning apparatuses are adapted for retracting the lengths of sutures to place soft tissue to which the sutures are attached in tension.
3. The suture management device as recited in claim 1 , wherein said center portion comprises a curved surface and a pair of posts for retaining the sutures in the center portion.
4. The suture management device as recited in claim 2 , wherein each of said tensioning apparatuses further comprises a sliding suture cleat for receiving an end of a suture length opposed to the end connected to the soft tissue to be tensioned, the sliding suture cleat sliding responsive to actuation of the suture tensioning control.
