摘要： Multi-fiber laser probes utilize relative motion of fibers and other laser probe elements to preserve small-gauge compatibility while providing for multi-spot beam deliver, or to provide for the selectively delivery of single-spot or multi-spot beam patterns. An example probe includes fibers having distal ends that are movable as a group onto a distal ramp element affixed to a distal end of a cannula, so that the distal ends of the fibers can be moved between a retracted position, in which the distal ends of the fibers are within the cannula or ramp element, and an extended position, in which distal ends of the fibers are guided by grooves or channels of the ramp so as to extend at least partially through external openings in the distal end of the laser probe and so as to be pointed angularly away from a longitudinal axis of the cannula.

摘要： The present disclosure relates to a laser probe assembly coupled to a laser system through an optical fiber cable. In one example, the laser probe assembly comprises a probe tip coupled to the probe body, the probe tip housing multiple fibers. Each of the multiple fibers comprises a proximal end that couples to the laser system and a distal end that terminates in the probe tip, a single core for transporting a laser beam provided by the laser system, and a cladding surrounding the core. The laser probe assembly also comprises a lens for projecting multiple laser beams provided by the multiple fibers on to a surgical site. Within the probe tip, parts of outer surfaces of portions of any two adjacent fibers of the multiple fibers touch. Also, the multiple fibers are at least substantially centered with respect to the lens.

摘要： Certain embodiments disclosed herein provide systems and devices for coupling optical fibers with laser surgical systems. In particular, certain aspects provide a push-pull connector and adapter for releasably coupling an optical fiber with a port of a laser surgical system. The connector and adapter facilitate mechanical lateral and rotational guidance of the optical fiber during insertion into the port to ensure proper alignment (e.g., clocking) of the optical fiber’s cores with a laser beam pattern propagated by the laser surgical system. Accordingly, the connector and adaptor enable improved coupling efficiency between the laser beam pattern and one or more cores of the optical fiber, and therefore improved power uniformity between multiple laser beams transmitted through the cores.

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.

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： In certain embodiments, a system for sensing occlusions in an optical system includes a first laser source configured to generate optical signals and a set of optical elements arranged to receive the optical signals from the first laser source and to direct the optical signals along a beam path. The system also includes a detector arranged to receive reflections of the optical signals traveling along at least a portion of the beam path and a control system communicably coupled to the detector. The control system is configured to detect, based on signals generated by the detector, reflection signals associated with the reflections of the optical signals, and disable a second laser source based on detection of the reflection signals.

摘要： A surgical microscope is configured to capture images of an eye of a patient and defines an optical axis. An illumination source is configured to emit a plurality of beams onto the eye of the patient at a plurality of angles relative to the optical axis. A controller is coupled to the surgical microscope and the illumination source, the controller configured to independently control values for illumination parameters for each beam of the plurality of beams to facilitate imaging of the eye of the patient. The illumination parameters may compensate for reflections from the iris, offset of the eye relative to the optical axis, and reflections of ambient light. The illumination parameters may be controlled subject to inputs received from a surgeon or other user.
