An illuminated surgical retractor system includes 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.

1. An illuminated surgical retractor system, said system comprising: a retractor having a front surface facing a surgical field, a rear surface, a distal and a proximal end and a shape, wherein the rear surface is adapted to engage tissue to expose the surgical field; anda light guide disposed over the front surface and conforming to the shape of the retractor and removably secured to the retractor to conduct light through the front or rear surfaces of the retractor, the light guide having an input adapter and one or more light emitting surfaces comprising a plurality of facets, and wherein the light guide has a cross-section with a width and thickness, the thickness changing from a proximal end of the light guide toward a distal end thereof, andwherein the light guide comprises a plurality of zones for illuminating the surgical field, and wherein the plurality of facets are disposed in the plurality of zones, and wherein at least some of the plurality of facets in a first zone are different than the plurality of facets in a second zone. 2. The system of claim 1, wherein at least one of the light emitting surfaces comprises a plurality of steps. 3. The system of claim 1, wherein at least one of the light emitting surfaces comprises a plurality of curved facets. 4. The system of claim 1, wherein the retractor is a McCulloch blade retractor. 5. The system of claim 1, wherein the retractor is a Caspar blade retractor. 6. The system of claim 1, wherein the retractor is an offset McCulloch blade retractor. 7. The system of claim 1, wherein the width of the light guide changes from the proximal end of the light guide to the distal end thereof. 8. The system of claim 1, wherein the input adapter comprises a round cross-section transitioning into a rectangular cross-section. 9. The system of claim 1, further comprising a light source providing illumination energy to the input adapter. 10. An illuminated surgical retractor system, said system comprising: a retractor having a front surface facing a surgical field, a rear surface, a distal and a proximal end, and a shape, wherein the rear surface is adapted to engage tissue to expose the surgical field; anda light guide coupled to the retractor and conforming to the shape thereof, the light guide disposed over the front surface and configured to conduct light therethrough, wherein the light guide has one or more light emitting surfaces comprising a plurality of facets, wherein some of the plurality of facets are disposed in a first zone, and some of the plurality of facets are disposed in a second zone, and wherein the facets in the second zone are different than the plurality of facets disposed in the first zone, and wherein the facets in the first zone illuminate a first part of the surgical field, and the facets in the second zone illuminate a second part of the surgical field different than the first part. 11. The system of claim 10, wherein the light guide comprises a cross-section having a width and a thickness, and wherein the thickness changes from a proximal end of the light guide toward a distal end thereof. 12. The system of claim 10, further comprising a light source for providing illumination energy to the light guide. 13. The system of claim 10, wherein a width of the light guide changes from a proximal end of the light guide to a distal end thereof. 14. The system of claim 10, wherein the light guide further comprises an input adapter for receiving light, the input adapter having a round cross-section transitioning into a rectangular cross-section.
