ABSTRACT:
A surgical retractor for exposing a carpal ligament through a small transverse incision along the wrist, comprising a blade having an arch-shaped configuration in cross-section which arch becomes generally flat at a tip section thereof, said tip being tapered in plan view and adapted to be initially inserted through the incision to facilitate advancement of the blade along a plane between the ligament and overlying skin and tissue and muscle structures to thereby progressively expose the ligament by distal retraction; and a light conduit extending through the arch of the blade and terminating in spaced relation to the tip to project light toward the tip to illuminate the area being distally retracted between the tip and conduit. A surgical method employing the novel retractor of this invention is also disclosed.
