1. A laser probe comprising:
- an optic fiber having an optic fiber distal end and an optic fiber proximal end;
a single flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end;
a handle having a handle distal end and a handle proximal end wherein the flexible housing tube distal end extends from the handle distal end;
a handle base of the handle having a handle base distal end and a handle base proximal end;
a handle end cap of the handle having a handle end cap distal end and a handle end cap proximal end;
a flexible housing tube guide of the handle;
an actuation control guide of the handle having an actuation control guide distal end and an actuation control guide proximal end;
an actuation mechanism guide of the handle;
an actuation mechanism having an actuation mechanism distal end and an actuation mechanism proximal end wherein the actuation mechanism is disposed in the actuation mechanism guide between the handle end cap proximal end and the handle base distal end;
an inner bore of the actuation mechanism;
a flexible housing tube housing of the actuation mechanism wherein the flexible housing tube is disposed in the flexible housing tube guide and the flexible housing tube housing and wherein the flexible housing tube is fixed in the flexible housing tube housing;
an auto-fixing actuation control of the actuation mechanism wherein the auto-fixing actuation control is disposed in the actuation control guide and wherein an actuation of the auto-fixing actuation control towards the actuation control guide distal end and away from the actuation control guide proximal end is configured to extend the actuation mechanism relative to the handle proximal end wherein the actuation mechanism actuates towards the handle distal end and away from the handle proximal end and wherein the actuation of the auto-fixing actuation control towards the actuation control guide distal end and away from the actuation control guide proximal end is configured to extend the flexible housing tube housing relative to the handle proximal end and extend the flexible housing tube relative to the optic fiber proximal end; and
an auto-fixing component wherein the auto-fixing component is disposed in an auto-fixing component housing of the handle and wherein a portion of the auto-fixing component is adjacent to a portion of the auto-fixing actuation control.

Abstract
A steerable laser probe may include a handle having a handle distal end and a handle proximal end, an auto-fixing actuation control, a flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end, a first flexible housing tube portion having a first stiffness, and an optic fiber disposed within an inner bore of the handle and the flexible housing tube. An actuation of the auto-fixing actuation control may gradually curve the flexible housing tube. A gradual curving of the flexible housing tube may gradually curve the optic fiber.
