MULTI-SPOT LASER SURGICAL PROBE USING FACETED OPTICAL ELEMENTS

摘要

An optical surgical probe includes a handpiece, a light guide within the handpiece, and a multi-spot generator at a distal end of the handpiece. The handpiece is configured to optically couple to a light source. The light guide is configured to carry a light beam from the light source to a distal end of the handpiece. The multi-spot generator includes a faceted optical element with a faceted end surface spaced from a distal end of the light guide. The faceted end surface includes at least one facet oblique to a path of the light beam.

1. An optical surgical probe, comprising:
a cylindrical cannula; a light guide partially within the cannula, the light guide configured to receive a light beam from a light source through a proximal end and to emit the light beam through a distal end; and a multi-spot generator at a distal end of the cannula, the multi-spot generator including an optical element with a faceted proximal surface, the optical element configured to receive the light beam from the light guide and to split the light beam into beam-components, wherein facets of the faceted proximal surface are curved to focus the beam-components to multiple spots in an image plane.
