Abstract: Miniature surgical forceps are formed from a one-piece tubular member by opposed longitudinal channels machined in a distal end thereof so as to establish a radially opposed pair of unitary forceps jaws. Most preferably, the opposed channels are formed in the distal end of the rigid tubular member by means of electron discharge machining (EDM) techniques. The resulting opposed cross-sectionally arcuate jaw sections may be bent and/or further shaped to achieve the desired final jaw configuration. The inner surfaces of the forceps jaws thereby established may have a filler material deposited in such a manner so as to change the overall shape and/or geometric configuration of the jaws and thereby engineer them to a specific surgical purpose.

Abstract: The present invention relates, in general, to a method of treating disorders of the eye, and, in particular, to a method of inducing posterior vitreous detachment.

Abstract: Surgical instruments, especially for opthalmological surgical procedures, have a smooth, bulbous arcuate tip that surrounds the distal end of a lumen. The tip may be translucent and flexible. Most preferably, the tip is formed of a compliant, yet self-supporting, material, such as medical grade transparent silicone elastomer. The bulbous arcuate tip may take various geometric forms, for example, generally spherical, ellipsoid or the like. The bulbous arcuate tip may be symmetrical about the elongate axis of the instrument or may be asymmetrical (i.e., angularly disposed) relative to such longitudinal axis. The surgical instruments of this invention are most preferably made by first adhering a length of compliant tubing (e.g., silicone) onto a distal end of a rigid tube (e.g., a section of a stainless steel needle). The proximal rigid tube section is preferably coaxially sleeved over, and affixed to, the distal compliant tube section.

Abstract: Hand-held instruments have an actuator assembly which may be employed to actuate a distally mounted tool by application of radial force about the entirety of the instrument circumference (i.e., is omni-actuatable). Most preferably, the actuator assembly includes a plurality of circumferentially spaced-apart generally L-shaped actuator levers defining respective arcuate bearing surfaces along exterior edge regions thereof, and a retaining ring which circumferentially bounds the actuator levers around the exterior edge regions thereof. The retaining ring most preferably defines an interior stationary arcuate guide surface in conformable mated relationship to the bearing surfaces of said actuator levers.

Abstract: This invention concerns the use of stainless steel, disposable tacks to be employed in the mechanical dilation of the iris during opthalmic surgery. Intended for temporary iris fixation, the tack is provided with a hook built onto its proximal end, and with a sharp anterior blade at its distal end. The anterior blade allows easy insertion of the tack through the peripheral cornea of the eye, at the limbal area, and an applicator is provided with a forked holder to firmly grasp the hook in securely placing and removing the tack in the surgical procedure.
