Illuminated laser probe with adjustable area of illumination
View Patent ↗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.

a laser optic fiber having a length with opposite proximal and distal ends, the laser optic fiber extending through the handle and the tip to the laser optic fiber distal end positioned adjacent the tip distal end and the illumination optic fiber distal end;
a mechanism on the handle, the mechanism being operatively connected to the laser optic fiber to move the laser optic fiber through the handle and the tip between a retracted position of the laser optic fiber where the laser optic fiber distal end is positioned adjacent the tip distal end and the illumination optic fiber distal end, and an extended position of the laser optic fiber where the laser optic fiber distal end is extended from the tip distal end and the illumination optic fiber distal end;
a portion of the laser optic fiber adjacent the laser optic fiber distal end having a curved configuration; and,
curved sleeve is mounted on the laser optic fiber distal end portion, and the curved sleeve holds the laser optic fiber distal end portion in the curved configuration.
