STEERABLE LASER PROBE

摘要

A steerable laser probe may include a handle having a handle distal end and a handle proximal end, an actuation control of the handle, a flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end, an optic fiber disposed within an inner portion of the handle and the flexible housing tube, and a cable disposed within the flexible housing tube and the actuation control. A rotation of the actuation control may be configured to gradually curve the flexible housing tube and the optic fiber. A rotation of the actuation control may be configured to gradually straighten the flexible housing tube and the optic fiber.

1. A method for performing an ophthalmic photocoagulation procedure comprising:
applying a force vector to an anterior end of an actuation control of a handle wherein the handle has a handle distal end and a handle proximal end and wherein the force vector is directed towards the handle proximal end and away from the handle distal end; rotating the actuation control in a handle inner portion of the handle until the actuation control is in a first fixed rotational position in the handle inner portion; curving a flexible housing tube and an optic fiber until the optic fiber is in a first curved position wherein the optic fiber is disposed in the flexible housing tube, the handle inner portion, and an actuation chamber of the actuation control that extends between a distal end of the actuation control and a proximal end of the actuation control and wherein the optic fiber has an optic fiber distal end and an optic fiber proximal end and wherein the flexible housing tube has a flexible housing tube distal end and a flexible housing tube proximal end; fixing the actuation control in the first fixed rotational position in the handle inner portion; aiming the optic fiber distal end at a first photocoagulation target; fixing the optic fiber in the first curved position; rotating the actuation control in the handle inner portion until the actuation control is in a second fixed rotational position in the handle inner portion; curving the flexible housing tube and the optic fiber until the optic fiber is in a second curved position; fixing the actuation control in the second fixed rotational position in the handle inner portion; and fixing the optic fiber in the second curved position.
