<p>A variable-rigidity, small-gauge illuminator is disclosed, one embodiment being a small-gauge illumination surgical system comprising: a light source (12) for providing a light beam; an optical cable (14), optically coupled to the light source for receiving and transmitting the light beam, a handpiece (10), operably coupled to the optical cable; an optical fiber (22), operably coupled to the handpiece, wherein the optical fiber is optically coupled to the optical cable to receive and transmit the light beam to illuminate an area; and a cannula (16), operably coupled to the handpiece, for housing and directing the optical fiber, wherein the cannula is operable to extend and retract from the handpiece to vary the length of the cannula extending from the handpiece, and wherein the optical fiber is operably connected to the cannula such that the distal end of the optical fiber and the distal end of the cannula remain co-incident as the length of the cannula extending from the handpiece is varied. The optical fiber, the cannula and the handpiece can be fabricated from biocompatible materials.</p> |
