Abstract

A retractor assembly for surgery in a patient includes at least one retractor member removably engageable to a support member. The retractor assembly includes a housing assembly engaged to the support member and to an arm that extends from a retraction portion of the retractor member. A drive mechanism in the housing assembly is coupled to the retractor member and is operable to rotate the retraction portion of the retractor member relative to the support member to a desired angular orientation.
