Multi-spot laser surgical probe using faceted optical elements

1. An optical surgical probe comprising:

a handpiece, the handpiece configured to optically couple to a light source;

at least one light guide within the handpiece; the at least one light guide configured to carry a light beam from the light source to a distal end of the handpiece;

a multi-spot generator at a distal end of the handpiece, the multi-spot generator including a faceted optical element with a faceted end surface spaced from a distal end of the light guide, the faceted end surface having planar facets, making an oblique angle with a path of the light beam, wherein

the multi-spot generator further including a spherically symmetric ball lens within the faceted optical element and is configured to split the light beam into multiple beam-components and to redirect the beam-components to multiple separate spots.

2. The optical surgical probe of claim 1 , wherein the faceted optical element has a concave faceted face.

3. The optical surgical probe of claim 1 , wherein the faceted optical element has a convex faceted face.

4. The optical surgical probe of claim 1 , wherein the faceted optical element comprises a faceted optical adhesive.

5. The optical surgical probe of claim 1 , wherein the light source comprises a laser.

6. The optical surgical probe of claim 1 , wherein the handpiece is configured to switch between optical coupling to a first light source producing light of a first wavelength and optical coupling to a second light source producing light of a second wavelength different from the first wavelength, wherein at least one of the first and second wavelengths is visible.

7. The optical surgical probe of claim 1 , wherein the distal end of the handpiece is sized to be 23 Gauge or smaller.
