Abstract

An illuminated surgical retractor includes a handle having an elongated first blade portion connected at one end to one end of the handle and an elongated second blade portion extending along the length of the first blade portion. One end of the second blade portion defines an illumination input end to which a connector is coupled. The connector is shaped to optically couple the illumination input end to a source of illumination so that at least a portion of one of the first and second blade portions is illuminated.

39. The illuminated surgical retractor of claim 1 wherein said source of illumination includes a light guide that receives light from a remote light source, and said second blade portion comprises a light emitting panel having a greater width than thickness and top and bottom surfaces, said panel having one or more light emitting areas along the length of one of said surfaces from which light is emitted for illuminating a viewing area in proximity of said retractor.

40. The illuminated surgical retractor of claim 1 wherein multiple light extracting deformities are provided on a surface of said second blade portion for directing light toward a viewing area in proximity of said retractor and reducing the intensity of a directional component of the light toward a viewing angle of a user of said

17. An illuminated surgical retractor comprising a handle having a first handle end portion and a second handle end portion, an elongated first blade section having a first blade proximal end portion and a first blade distal end portion with a first blade inner surface extending between the first blade proximal end portion and the first blade distal end portion, the second handle end portion of said handle connected to the first blade distal end portion of said first blade section, an elongated second blade section having a second blade proximal end portion and a second blade distal end portion with a second blade outer surface extending between the second blade proximal end portion and the second blade distal end portion and a second blade inner surface extending between the second blade proximal end portion and the second blade distal end portion, the second blade distal end portion of said second blade section defining an illumination input end portion, and a connector coupled to the illumination input end portion, said connector shaped to optically couple the illumination input end portion to a source of illumination so that at least one of said first blade section and said second blade section is illuminated substantially the entire length thereof.
