<p>A transparent illuminated infusion and incision cannula is provided for illuminating an area during eye surgery. An endo-illuminator (103,204) comprises a hose (104) operable to transport a fluid, a protective sheath (210) operable to combine the endo-illuminator and hose within a single cable, an incision cannula (602) operable to incise the sclera of the eye, and a transparent cannula (108) surrounding the incision cannula, wherein the transparent cannula is positioned coaxially with the endo-illuminator and a space is defined between a distal end of the endo-illuminator and proximal end of the transparent cannula. The incision cannula (602) is spring-biased between a retracted position and an extended position, such that in its initial position, the incision cannula is extended to enable an incision in the sclera to be made, and is adapted to be retractable to a second position so as to leave the endo-illuminator (103,204) and transparent cannula (108) in their correct relative positions, such that the space between the distal end of the endo-illuminator and proximal end of the transparent cannula allows fluid to flow around the distal end of the endo-illuminator, into the transparent cannula, and into a sclera aperture.</p> |
