Abstract

A shaped surgical retractor blade is used in a surgical retractor assembly. The shaped retractor blade is not formed of sheet material but rather is formed to have a non-uniform thickness between the tissue contacting side and the surgical arena side. The non-uniform thickness can be provided by a longitudinally running rib running between two recesses on surgical arena side of the retractor blade. The recesses provide openings through which the surgeon can better view the surgical arena. The rib provides additional bending strength to the retractor blade. The tissue contacting side of the blade can have a convex curvature, minimizing the possibility of tissue damage at the location that the blade contacts the tissue. The retractor blade can have a constant longitudinally extending section and a distal, tapering section. The uniquely shaped retractor blade can be formed, for instance, such as by injection molding a high tensile strength polymer material which provides desired optical/fluoroscopic/magnetic resonance imaging properties.
