Abstract
A retractor having an elongated body that provides access to a surgical location within a patient. The elongate body includes a plurality of segments that are connected to one another through a plurality of ratcheting mechanisms. The ratcheting mechanisms permit relative movement of the segments with respect to one another when expander dilators are inserted within the retractor. The segments are surrounded and retained by a resilient elastomeric sleeve or bands. The distal end surfaces of the segments include thin edges that are configured to mobilize, dissect, split and retract the terminal tissues in the surgical area. The retractor may be used in conjunction with a shim.
