Abstract
A steerable laser probe may include a handle having a handle distal end and a handle proximal end, an actuation lever of the handle, a flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end, and an optic fiber disposed within an inner bore of the handle and the flexible housing tube. An actuation of the actuation lever may gradually curve the flexible housing tube and the optic fiber. An actuation of the actuation lever may gradually straighten the flexible housing tube and the optic fiber.
Claims6
A method of operating a steerable laser probe, comprising:
- reducing a force applied to a portion of an actuation lever of a handle of the steerable laser probe wherein the handle has a handle distal end and a handle proximal end and wherein the actuation lever has an actuation lever distal end and an actuation lever proximal end;
- limiting an actuation of the actuation lever by a pivot pin wherein the pivot pin is disposed in a pivot pin housing of the handle and a pivot pin chamber of the actuation lever;
- actuating the actuation lever in an actuation lever channel of the handle;
- actuating the actuation lever proximal end towards the handle distal end and away from the handle proximal end wherein the actuation lever proximal end is disposed in an actuation lever guide and wherein the actuation lever distal end is not disposed in the actuation lever guide;
- actuating an optic fiber housing of the actuation lever within the actuation lever guide towards the handle distal end and away from the handle proximal end in association with an optic fiber having an optic fiber distal end and an optic fiber proximal end;
- straightening a flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end wherein the flexible housing tube proximal end is disposed in an optic fiber guide of the handle and wherein the flexible housing tube proximal end is fixed in the optic fiber guide;
- and
- straightening the optic fiber wherein the optic fiber is disposed in the actuation lever guide, the optic fiber housing, the optic fiber guide, and the flexible housing tube wherein the optic fiber distal end is adjacent to the flexible housing tube distal end and wherein a portion of the optic fiber is fixed to an inner portion of the flexible housing tube.
