ABSTRACT:
A surgical retractor is disclosed for use when surgery is performed adjacent a bone and remains in place for an appropriate duration without requiring manual assistance. A barrier member includes a plurality of cannulated fixation posts for its temporary placement on, and attached to, the bone and a soft tissue engaging surface which extends transverse of a surface of the bone. Guides, including the cannulated fixation posts, slidably receive mounting pins which supplement the fixation posts for temporarily attaching the barrier member to the bone. The barrier member is also provided with bottom and top flanges which extend transversely of the soft tissue engaging surface and cooperate therewith to prevent entry of the soft tissue into an adjacent surgical site.
