Abstract
The present invention describes a system comprised of a wedge, distractor channel, and a retractor. The wedge and distractor channel are combined in a nesting relationship and an impactor handle is then attached to the wedge/distractor channel combination to facilitate intervertebral positioning. Subsequent to insertion, the wedge is slidably disengaged while leaving the distractor channel in place, thereby forming an access port which provides an enhanced field of view of the interior spinal anatomy. A retractor is positioned in the incision allowing unobstructed view from outside the body to the access port and facilitates performance of such surgical procedures as discectomy, implant sizing and insertion, spinal fusion, and the like.
