Abstract

A surgical access device including a frame, first and second supports, and first and second retractor blades releasably coupled with the first and second supports, respectively. The frame has first and second arms. The first support is releasably coupled with the first and second arms. The second support is slidably mounted on the first and second arms. The second support is movable between a first position with the retractor blades in close cooperative position and a spaced apart position with respect to the first support. The first and second retractor blades each have a distal end portion configured and adapted to engage a vertebral body. In one method of use, the retractor is inserted through an incision in first orientation with the blades in close approximation and rotated approximately 90°, before spreading the retractor blades to retract tissue.

Claims (20)

1. A kit for spinal surgery comprising:

a retractor device having:

a first support;

a second support movable between a first position adjacent the first support and a second position spaced apart from the first support; and

first and second retractor blades releasably coupled to the first and second supports, respectively, the first and second retractor blades assuming a position in close approximation when the first and second supports are in the first position, and a second, open position when the first and second supports assume the second position spaced apart from one another, a distal end portion of each of the first and second retractor blades defining a recess having an arcuate portion configured and dimensioned to engage a vertebral body;

a dissector;

a guide wire; and

a fixation pin.

2. The kit according to claim 1 , further including a surgical implant.

3. The kit according to claim 2 , further comprising a disc spreader.

4. The kit according to claim 1 , wherein each of the first and second retractor blades defines a longitudinal groove, whereby when the first and second retractor blades are in a close cooperative position the grooves define a lumen.

5. The kit according to claim 4 , wherein the longitudinal groove is configured and dimensioned to receive a fixation pin therethrough.

6. The kit according to claim 1 , further comprising an auxiliary blade adapted to be transversely mounted on one of the first and second refractor blades.

7. The kit according to claim 6 , wherein the auxiliary blade includes a longitudinal groove.

8. The kit according to claim 6 , further comprising an intradiscal shim adapted to engage the longitudinal groove of the auxiliary blade.

9. The kit according to claim 1 , wherein the dissector includes indicia thereon marking a distance from a distal end of the dissector.

10. The kit according to claim 1 , wherein the recess of the respective first and second retractor blades has a concave profile.

11. The kit according to claim 1 , wherein the recess of the respective first and second retractor blades extends along a longitudinal axis of the respective first and second retractor blades.

12. The kit according to claim 1 , wherein the arcuate portion of the recess has a radius of curvature ranging from about 0.1 inch to about 1.0 inch.

13. The kit according to claim 12 , wherein the radius of curvature of the arcuate portion of the recess is about 0.6 inch.
