Thermally controlled illumination devices

摘要: An illumination element such as an optical waveguide for illuminating a surgical field in patient has light input section, transmitting and output section. The section is optically coupled to proximal of the inputs into element. transmits preferably by total internal reflection or other transmission means. adjacent distal which extraction area from exits with energy density. large enough maintain density at level that prevents melting burning patient, profile does not interfere access field.
