Abstract

Abstract An illuminated surgical instrument has a working area located near an end of the instrument. An array of optical fibers terminates near the end of the instrument. The array of optical fibers is located adjacent to the instrument such that the array of optical fibers provides targeted illumination to the working area only on one side of the instrument.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 150 words
An illuminated vitrectomy probe comprising: a vitrectomy probe having a cutting port disposed at a distal end of a cannula; and an array of optical fibers extending along a portion of the cannula and terminating near the cutting port, the array of optical fibers comprising: a first optical fiber; and a plurality of optical fibers flanking the first optical fiber on opposite sides thereof, the first optical fiber having a diameter larger than the diameters of the flanking optical fibers, the array of optical fibers arranged along the cannula such that the flanking optical fibers have progressively decreasing diametrical sizes away from the first optical fiber, the array of optical fibers located adjacent to the cannula only on a side of the cannula on which the cutting port is located, and wherein the array of optical fibers are disposed in a semi-circular pattern around the cannula near the cutting port.
Claim 2
Dependent Claim 150 words
An illuminated vitrectomy probe comprising: a vitrectomy probe having a cutting port disposed at a distal end of a cannula; and an array of optical fibers extending along a portion of the cannula and terminating near the cutting port, the array of optical fibers comprising: a first optical fiber; and a plurality of optical fibers flanking the first optical fiber on opposite sides thereof, the first optical fiber having a diameter larger than the diameters of the flanking optical fibers, the array of optical fibers arranged along the cannula such that the flanking optical fibers have progressively decreasing diametrical sizes away from the first optical fiber, the array of optical fibers located adjacent to the cannula only on a side of the cannula on which the cutting port is located, and wherein the array of optical fibers are disposed in a semi-circular pattern around the cannula near the cutting port.
