high productivity internal light probe. The present invention relates to a surgical lighting system and a high productivity internal illuminator. One embodiment of the high throughput internal illuminating surgical system comprises: a light source for providing a beam of light； a proximal optical fiber optically coupled to the light source for receiving and transmitting the light beam； a distal optical fiber, optically coupled to the distal end of the proximal optical fiber, to receive the light beam and emit the light beam to illuminate a surgical field； wherein the distal fiber optic comprises a tapered section having a proximal end diameter larger than the distal end diameter； a handpiece operably coupled to the distal fiber optic； and a cannula operably coupled to the handpiece for housing and directing the distal optic fiber. the diameter of the proximal end of the tapered section may be the same as the diameter of the proximal fiber optic and, for example, may be of a 20 gauge diameter. the diameter of the distal end of the tapered section, for example, may be of a diameter 25 gauge compatible. the cannula may be a 25 gauge inner diameter cannula. the proximal optic fiber may preferably have one equal to or greater than that of the light beam source and the distal optic fiber may preferably be provided with a superior to that of the proximal fiber optic and superior to that of the light beam source at any point in the distal optical fiber (since the beam of light may increase as it travels through the tapered section).sonda iluminadora interna de alta produtividade. a presente invenção se refere a um sistema cirúrgico de iluminação e a um iluminador interno de alta produtividade. uma modalidade do sistema cirúrgico iluminador interno de alta produtividade compreende: uma fonte de luz para proporcionar um feixe de luz； uma fibra ótica proximal, oticamente acoplada à fonte de luz para receber e transmitir o feixe de luz； uma fibra ótica distal, oticamente acopla
