Abstract: A microsurgical laser probe primarily used in ophthalmic surgery provides both laser light and illumination light to a surgical site from a single light source. The laser probe has a dual core optic fiber that transmits both laser light and illumination light to the surgical site. A center core of the optic fiber transmits the laser light through the optic fiber and emits the laser light at the surgical site. The center core of the fiber is surrounded by an outer fiber core. The outer fiber core transmits illumination light through the optic fiber and emits the illumination light at the surgical site.

Abstract: A microsurgical laser probe is provided with a distal end portion of an optic fiber that projects from a tubular sleeve of the probe and can be caused to bend relative to the probe sleeve by manual manipulation of a mechanism on a handle of the probe.

Abstract: An ophthalmic surgery light transmitting apparatus has an optic fiber having a flexible length with a light source connector mounted on one end of the optic fiber and the opposite end of the optic fiber being adapted to be mounted to an ophthalmic surgery instrument to provide illumination for the instrument. The cross-sectional area of the optic fiber transitions as it extends from the end connected to the light source connector to the opposite end of the optic fiber. The optic fiber transitions from a larger cross-sectional area of the optic fiber at the light source connector to a smaller cross-sectional area of the optic fiber at the opposite end.

Abstract: An ophthalmic surgery illuminated directional laser probe has a handle and a rigid tubular tip projecting from the handle, and has an illumination optic fiber and a laser optic fiber that extend through the handle and the tip. A mechanism on the handle is operable to extend distal ends of the illumination optic fiber and the laser optic fiber from the distal end of the instrument tip, and to retract the distal ends of the illumination optic fiber and the laser optic fiber back into the interior of the tip. At least one of the distal ends of the illumination optic fiber and the laser optic fiber is held in a curved configuration. The distal ends of the illumination optic fiber and the laser optic fiber are secured to each other, whereby both the illumination optic fiber and the laser optic fiber curve into a bent configuration as the distal ends of the illumination optic fiber and the laser optic fiber are extended from the distal end of the instrument tip.

Abstract: A microsurgical laser probe has a handle and a tubular tip that projects from the handle, and three optic fibers that extend through the handle and the tip. One of the optic fibers is a laser optic fiber that is adapted to be connected to a source of laser light at one end of the laser optic fiber, and to transmit the laser light from the opposite end of the laser optic fiber at the distal end of the instrument tip. The other two optic fibers are illumination light optic fibers. Each illumination light optic fiber has one end that is adapted to be connected to a illumination light source, and an opposite end that projects the illumination light from the distal end of the instrument tip. By providing two laser light optic fibers in the instrument, the amount of illumination directed to the surgical site being accessed by the laser optic fiber is effectively doubled.

Abstract: 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.

Abstract: Disposable, bipolar electrosurgical forceps are designed to prevent the sticking of body tissue to the tips of the forceps and include a pair of electrode arms having lengths with opposite proximal and distal ends, with thin layers of biocompatible metal on the forceps arm distal ends and bipolar electrical conductors permanently secured to the forceps arm proximal ends.

Abstract: A multiple target ophthalmic surgery instrument is comprised of a single primary optic fiber that transmits laser light to the instrument, and a plurality of additional optic fibers that receive the laser light from the primary optic fiber and project the laser light as a plurality of beams from the plurality of additional optic fibers. In this manner, the instrument splits the single laser light beam received from a single laser light source into the multiple of laser beams and targets the multiple laser beams at multiple spots of a surgical site in the eye.

Abstract: An optic fiber surgical instrument is removably connectable to a surgical light source. The instrument is provided with an optic fiber connector and a separate auxiliary or electric identification connector. The optic fiber connector is removably connectable to a laser light output of a laser light source to convey the laser light through the optic fiber of the instrument, whereby manipulation of the instrument by a user can direct the laser light to a surgical site. The auxiliary connector is connectable to a ground connection of the surgical light source to establish an electric circuit through the instrument and the surgical light source, whereby an electrical identification device on the instrument identifies the instrument for the surgical light source.

Abstract: An assembly used to adapt an external post connector, such as a BNC type connector of a microsurgical optic fiber instrument to a threaded SMA type bushing of a light source includes an adapter that can be threaded on the bushing of the light source and is also connectable to the BNC connector.

Abstract: An illuminated laser probe primarily designed for ophthalmic surgery provides both illumination light to a surgical site and laser light to the surgical site. The probe has an elongate handle with a tubular tip extending from a distal end of the handle. A length of illumination optic fiber and a length of laser optic fiber extend through the handle and the tip. A mechanism is provided on the handle at a position where the mechanism can easily be manipulated by a finger of a surgeons hand holding the handle. The mechanism is operatively connected with the laser optic fiber and is manipulated to selectively extend a distal portion of the optic fiber from the instrument tip and retract the distal portion of the optic fiber back into the instrument tip.

Abstract: A surgical instrument handle is removably attachable to a surgical instrument head for operation of a microsurgical instrument on the head by manipulation of the instrument handle. The instrument handle has an elongate center rod with a piston mounted on the rod for reciprocating movement. The piston engages with a piston in the attached surgical instrument head for operation of the microsurgical instrument of the head. A tapered ring is mounted on the rod and engages with the piston for reciprocating the piston. A plurality of resilient arms extend along the length of the rod and engage against a sliding surface of the ring. The plurality of resilient arms are alternatively squeezed radially inwardly by the surgeon's hand and released by the surgeon's hand to allow the resilient arms to flex radially outwardly. The inward and outward movement of the plurality of anns reciprocates the piston on the handle rod to cause operation of the surgical instrument head.
