  • Patent number: 5060062
    Abstract: A visual sensory aid system for the partially sighted, designed to be worn around the eyes in a manner similar to that of eyeglasses. Light incident to the image source is detected by receptors mounted on the front lens and processed by the electronic circuitry. The resulting signals, representative of the image, are transmitted to monitor areas on an interior lens that extends from beyond the periphery of one eye to beyond the periphery of the other. The right and left images displayed on the monitor areas are reversed at a high frequency in order to simulate a visual stereo effect for depth perception. Areas of the monitors corresponding to blind spots of the eye are electronically inactivated. A feedback system maintains the focal point of the eye in the optimum direction.

  • Patent number: 4609368
    Abstract: A surgical handpiece having an ultrasonically driven tool operated by gas under pressure. A surgical handpiece useable for ophthalmic and other microsurgery uses a whistle for generating ultrasonic waves and causing a driving member to reciprocate at ultrasonic frequency. The handpiece has a probe with a needle or other tool reciprocable within the probe. Irrigation liquid can be supplied through the handpiece and through the probe, surrounding the tool to remove heat. The tool has a lumen, and the lumen is connected to a source of vacuum through the handpiece for aspiration of tissue fragmented by the reciprocating tool.

  • Patent number: 4414974
    Abstract: A disposable, or one-time-use microsurgical knife has a slidable shroud that can be moved into a forward position to protect the blade, and can be moved rearwardly to allow use of the knife. The shroud, as well as other parts of the knife, are made of plastic, and a phosphorescent material is included to render the knife luminescent during steps taken in a darkened operating room. The extremely sharp razor chip blade includes a shank selectively wedged into the knife body so blades are interchangeable.

  • Patent number: 4316465
    Abstract: An ophthalmic handpiece is disclosed. The handpiece includes coaxial irrigation and aspiration needles, with passageways through the body of the handpiece for connection to conventional equipment for supplying irrigation and aspiration. Within the aspiration needle, there is a reciprocating cutting device for cutting tissue, that extends into the aspiration needle. The cutting device is moved by a driving device that rotates as it moves, to rotate the cutting device during the cutting motion. The aspiration passageway is also provided with a supply for reflux irrigation to assist in removal of tissue from the aspiration port.
