Abstract
A surgical instrument for use in penetrating and working in the vitreous humor of an eye comprises a finger grip member and a rigid needle extending from the finger grip member, with a single continuous fiber optic member extending from a distal end of the needle through the needle and the finger grip member to a cone shaped proximal end contained in a large connecting member constructed of heat conductive material. The surgical instrument includes a stripping tool at its distal end that is bent at a right angle and positioned in a plane that is parallel to the longitudinal axis of the needle but does not intersect this axis. The surgical instrument also comprises an infusion/aspiration system including a hollow pipe attached to the needle that extends parallel to the longitudinal axis of the needle but does not interfere with a beam of light projected from the distal end of the fiber optic member extending through the needle. The instrument also includes a coaxial bipolar diathermy comprising an exterior needle surrounding and coaxial to the fiber optic needle, the exterior needle being insulated from the interior fiber optic needle and both needles being electrically connected to a conventional radio frequency generator for creating an electric potential between the distal ends of the interior and exterior needles for use in coagulating bleeding vessels on a retinal surface or beneath pre-retinal membranes.
