A surgical retractor includes a retractor body and a retractor arm. The retractor arm includes a control assembly includes a base member having a first opening and a second opening, and movable between a first position and second position. The retractor arm further includes a regulating member to control rotation of the base member and move through the first opening of the base member, a connecting member cooperatively connected to the regulating member, and a barrel member in operative slidable engagement with the second opening formed in the base member. Rotation of the regulating member in a selected direction moves a stem of the regulating member through the first opening thereby forcing the barrel member to slide along the second opening and the base member to pivot relative to the retractor arm between a first position and second position, thereby rotating a connected retractor blade.
