Abstract
A percutaneous surgical retractor is provided for performing examinations or surgical procedures through the skin. The retractor has an outer sleeve structure with a proximal and an open beveled distal end. A blade is slidable within the outer sleeve and moveable between at least a deployed position and a retracted position. The retracting blade substantially closes the open beveled distal end of the outer sleeve when the blade is in the retracted position to inhibit the coring of tissue by the outer sleeve during percutaneous insertion. The retractor has structure for deploying the retracting blade relative to the outer sleeve.
