Abstract
A surgical probe includes a cannula assembly, having a graded index (GRIN) fiber that is configured to receive a multi-spot light beam at a proximal end and to emit the multi-spot light beam at a distal end ; an adapter, having a distal end, configured to receive the cannula assembly, with the proximal end of the GRIN fiber, a proximal end, configured to couple to a light guide via a connector and to receive a light delivered by the light guide from a laser source to the adapter, and an interface, configured to couple the light delivered by the light guide to the proximal end of the GRIN fiber; wherein a length of the GRIN fiber is sufficiently long that the interface is outside a patient's eye during a photocoagulation procedure.
Claims14
A surgical probe, comprising:
- a cannula assembly, having a graded index (GRIN) fiber that is configured to receive a multi-spot light beam at a proximal end and to emit the multi-spot light beam at a distal end;
- an adapter, having
- a distal end, configured to receive the cannula assembly, with the proximal end of the GRIN fiber,
- a proximal end, configured to couple to a light guide via a connector and to receive a light delivered by the light guide from a laser source to the adapter, and
- an interface, configured to couple the light delivered by the light guide to the proximal end of the GRIN fiber;
- wherein
- a length of the GRIN fiber is sufficiently long that the interface is outside a patient's eye during a photocoagulation procedure.
A method to fabricate a surgical probe, the method comprising:
- encasing a graded index (GRIN) fiber into a cannula system, the GRIN fiber configured to receive a multi-spot light beam at a proximal end and to emit the multi-spot light beam at a distal end;
- coupling the cannula system, with the proximal end of the GRIN fiber, to a distal end of an adapter;
- and
- coupling a light guide via a connector to a proximal end of the adapter, the light guide configured to deliver light from a laser source to the adapter;
- wherein
- the adapter comprises an interface, configured to couple the light delivered by the light guide to the proximal end of the GRIN fiber;
- and
- a length of the GRIN fiber is sufficiently long that the interface is outside a patient's eye during a photocoagulation procedure.
