Abstract:
1. A variable intensity illuminator, comprising: an optical fiber, optically coupled to a light source and operable to receive a light beam from the light source and transmit the light beam to illuminate a surgical field; a handpiece, operably coupled to the optical fiber; a translucent cannula, operably coupled to the handpiece, for housing and directing the optical fiber, wherein the cannula is operable to diffuse and transmit the light beam to provide general illumination of the surgical field when a distal end of the optical fiber is retracted into the cannula; and wherein the distal end of the optical fiber is operable to transmit the light beam to provide spot lighting of the surgical field when the distal end of the optical fiber is co-incident with a distal end of the cannula.
