ILLUMINATED INFUSION CANNULA

摘要

A transparent illuminated infusion cannula is described. The cannula includes an endo-illuminator operable to provide light to illuminate an area within an eye; a hose to transport a fluid; a protective sheath; an incision cannula to incise the sclera of the eye and a transparent cannula surrounding the incision cannula. The transparent cannula is positioned coaxially with the endo-illuminator and a 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. In its initial position, the incision cannula is extended to enable an incision in the sclera to be made, and is retractable such that the endo-illuminator and the transparent cannula are in their correct relative positions to provide the optimal combination of light transmittance and fluid flow.
