摘要： In certain embodiments, an illuminating endoprobe system includes one or more light sources, a housing, a vitreous visualization fiber, and a general illumination fiber. The light sources generate a visualization light and an illumination light. The housing receives the visualization and illumination light, and has a probe tip with a probe axis. The vitreous visualization fiber transmits the visualization light through the probe tip. The visualization light has a visualization axis and a visualization beam angle at the probe tip. The general illumination fiber transmits the illumination light through the probe tip. The illumination light has an illumination axis and an illumination beam angle at the probe tip. The illumination beam angle is greater than the visualization beam angle, and the illumination axis is at an offset angle relative to the visualization axis, where the offset angle greater than 5 degrees.

摘要： Certain aspects of the present disclosure provide a thermally robust laser probe assembly comprising a cannula, wherein one or more optical fibers extend at least partially through the cannula for transmitting laser light from a laser source to a target location. The probe assembly further comprises a lens housed in the cannula and a protective component press-fitted to the distal end of the cannula, wherein the lens is positioned between the one or more optical fibers and the protective component.

摘要： An example illuminated microsurgical instrument comprises a handpiece, a tubular member connected to the handpiece to perform a medical procedure at an interventional site, a sheath member surrounding a portion of the tubular member and extending toward the distal tip of the tubular member, and an optical fiber positioned within the sheath member and connected to the sheath member, wherein a distal tip of the optical fiber is recessed within the sheath member and directed toward the distal tip of the tubular member. The sheath member and distal tip of the optical fiber may be movable between a proximal position at a first distance from the distal tip of the tubular member and a distal position at a second distance from the distal tip of the tubular member, wherein the second distance is shorter than the first distance. Movement of the sheath member moves the distal tip of the optical fiber to generate a wider illumination or a narrower illumination on the site being visualized.

摘要： An example multi-fiber, multi-spot laser probe comprises a plurality of fibers extending from a proximal end of the laser probe to at least near a distal end of the laser probe, where the proximal end of the laser probe is configured to be coupled to a laser source via an adapter interface, and a cannula having a distal end and surrounding the plurality of fibers along at least a portion of the laser probe at or near the distal end of the laser probe, where a distal end of each of the plurality of fibers is angle-polished so that the distal end of each fiber is angled relative to a longitudinal axis of the cannula and relative to a plane perpendicular to the longitudinal axis of the cannula. Additional embodiments employ lensed fibers, a distal window, ball lens, lens array, or faceted wedge.
