摘要： An adjustable ophthalmic surgery chandelier illuminator has a glass optic fiber with a conical exterior surface at its distal end that disburses illumination in the interior of the eye. The glass fiber is contained in a retractable needle that has a long, sharp beveled surface that facilitates insertion of the needle and the optic fiber into the eye, and then is retracted relative to the fiber distal end to adjust the field of illumination inside the eye.

摘要： A flexible walled cannula apparatus and method of use comprising a uniquely deformable cannula tube and head in combination with a uniquely shaped obturator which allows the use of heretofore unusable larger gauge surgical instruments while providing a self sealing incision. The apparatus and method of use provides a preassembled obturator and cannula assembly with which the surgeon forms an incision or channel, inserts the cannula tube, and through the cannula inserts surgical instruments to perform a surgical operation. The apparatus and method of use is especially suited for ophthalmic surgical operations. Alternative embodiments for use with even larger diameter instruments utilize a uniquely designed valve having leaflets which prevent bodily or other fluid leakage from the cannula when an instrument is not inserted.
