Abstract
In an example, a surgical retractor includes an elongated shaft extending from a first end to a second end, and a retractor blade extending from the second end of the elongated shaft. The elongated shaft defines an internal chamber. The elongated shaft includes a handle portion at the first end of the elongated shaft, a suction conduit in a first lateral portion of the internal chamber, and a light conduit in a second lateral portion of the internal chamber. The suction conduit extends from a suction port at the first end to a suction aperture at the second end. The light conduit extends from a light-input port at the first end to a light aperture at the second end. The suction conduit and the light conduit are substantially coplanar. The surgical retractor also includes an optical waveguide in the light conduit of the elongated shaft.
