Abstract
Light is directed between the arms of a forceps to illuminate an area under debridement of foreign material with a color selected to enhance contrast of foreign material that needs to be removed. The light comes from a multicolor source such as an LED chip having RGBW dies and is transmitted by a light transmitting element such as an elongated waveguide or a light pipe to illuminate the area under examination. The color is selectable so as to obtain a color that has good contrast for the foreign material. The apparatus has a docking station to install the forceps so that it is properly located with respect to the illumination. A camera can be part of the apparatus to transmit imagery to a display.
