Abstract
An apparatus for the efficient provision of directed illumination to a subdermal surgical field that is attachable to or completely forms a surgical retractor blade. This illuminated surgical retractor system may include a retractor and a light guide disposed over the retractor. The retractor has a front surface facing a surgical field, a rear surface adapted to engage tissue, a distal end, and a proximal end. The light guide conforms to the shape of the retractor and is removably secured to the retractor and conducts light through the front or rear surface of the retractor. The light guide has an input adaptor and one or more light emitting surfaces.
