US Patent 10478266 Illuminated surgical probe having multiple optical fibers

A surgical probe system comprising a surgical probe having a probe needle, a first optical fiber incorporated onto the probe needle, wherein a distal end of the first optical fiber projects a first beam of illumination light over a tip of the probe needle when activated; a second optical fiber incorporated onto the probe needle, wherein a distal end of the second optical fiber projects a second beam of illumination light over the tip of the probe needle when activated; and a third optical fiber incorporated onto the probe needle, wherein a distal end of the third optical fiber projects a third beam of light over the tip of the probe needle to perform a distance measurement between the probe needle and a patient's when activated, wherein the distance measurement is displayed or audibly presented to aid a user in probe positional awareness with respect to the patient's retina.
