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

Claims

1. A method for using a laser probe comprising:

applying a first force to an auto-fixing actuation control of a handle, the auto-fixing actuation control disposed adjacent to an auto-fixing component of the handle wherein the auto-fixing actuation control is disposed between an auto-fixing component distal end and an auto-fixing component proximal end and wherein the handle has a handle distal end and a handle proximal end and wherein the handle has a handle base and a handle end cap wherein a portion of the handle base is disposed in a portion of the handle end cap;

actuating the auto-fixing actuation control within an actuation control guide of the handle until the auto-fixing actuation control is in a first desired position within the actuation control guide;

actuating an actuation mechanism of the handle within an actuation mechanism guide of the handle;

extending a housing tube relative to the handle proximal end wherein the housing tube has a housing tube distal end and a housing tube proximal end and wherein a portion of the housing tube is disposed in a housing tube guide of the handle;

curving the housing tube;

curving an optic fiber to a first curved position relative to the housing tube proximal end wherein the optic fiber has an optic fiber distal end and an optic fiber proximal end and wherein the optic fiber proximal end is disposed in a light source interface;

removing the first force from the auto-fixing actuation control;

fixing the auto-fixing actuation control in the first desired position within the actuation control guide by a force between the auto-fixing actuation control and the auto-fixing component;

fixing the optic fiber in the first curved position relative to the housing tube proximal end;

applying a second force to the auto-fixing actuation control;

actuating the auto-fixing actuation control within the actuation control guide of the handle until the auto-fixing actuation control is in a second desired position within the actuation control guide;

curving the optic fiber to a second curved position relative to the housing tube proximal end;

fixing the auto-fixing actuation control in the second desired position within the actuation control guide by the force between the auto-fixing actuation control and the auto-fixing component; and

fixing the optic fiber in the second curved position relative to the housing tube proximal end.

2. The method of claim 1 further comprising:

inserting the housing tube into a cannula.

3. The method of claim 1 further comprising:

extracting the housing tube from a cannula.

4. The method of claim 1 further comprising:

compressing a portion of the housing tube.

5. The method of claim 1 further comprising:

extending the housing tube relative to the optic fiber.

6. The method of claim 1 further comprising:

curving the optic fiber within an eye.

7. The method of claim 6 further comprising:

curving the optic fiber within the eye without increasing a length of the optic fiber within the eye.

8. The method of claim 6 further comprising:

curving the optic fiber within the eye without decreasing a length of the optic fiber within the eye.

9. The method of claim 1 further comprising:

curving the optic fiber at least 45 degrees relative to the housing tube proximal end.

10. The method of claim 9 further comprising:

curving the optic fiber at least 90 degrees relative to the housing tube proximal end.

11. A method for using a laser probe comprising:

applying a first force to an auto-fixing actuation control of a handle, the auto-fixing actuation control disposed adjacent to an auto-fixing component of the handle wherein the auto-fixing actuation control is disposed between an auto-fixing component distal end and an auto-fixing component proximal end and wherein the handle has a handle distal end and a handle proximal end and wherein the handle has a handle base and a handle end cap wherein a portion of the handle base is disposed in a portion of the handle end cap;

actuating the auto-fixing actuation control within an actuation control guide of the handle until the auto-fixing actuation control is in a first desired position within the actuation control guide;

actuating an actuation mechanism of the handle within an actuation mechanism guide of the handle;

retracting a housing tube relative to the handle proximal end wherein the housing tube has a housing tube distal end and a housing tube proximal end and wherein a portion of the housing tube is disposed in a housing tube guide of the handle;

straightening the housing tube;

straightening an optic fiber to a first straightened position relative to the housing tube proximal end wherein the optic fiber has an optic fiber distal end and an optic fiber proximal end and wherein the optic fiber proximal end is disposed in a light source interface;

removing the first force from the auto-fixing actuation control;

fixing the auto-fixing actuation control in the first desired position within the actuation control guide by a force between the auto-fixing actuation control and the auto-fixing component;

fixing the optic fiber in the first straightened position relative to the housing tube proximal end;

applying a second force to the auto-fixing actuation control;

actuating the auto-fixing actuation control within the actuation control guide of the handle until the auto-fixing actuation control is in a second desired position within the actuation control guide;

straightening the optic fiber to a second straightened position relative to the housing tube proximal end;

fixing the auto-fixing actuation control in the second desired position within the actuation control guide by the force between the auto-fixing actuation control and the auto-fixing component; and

fixing the optic fiber in the second straightened position relative to the housing tube proximal end.

12. The method of claim 11 further comprising:

inserting the housing tube into a cannula.

13. The method of claim 11 further comprising:

extracting the housing tube from a cannula.

14. The method of claim 11 further comprising:

decompressing a portion of the housing tube.

15. The method of claim 11 further comprising:

retracting the housing tube relative to the optic fiber.

16. The method of claim 11 further comprising:

straightening the optic fiber within an eye.

17. The method of claim 16 further comprising:

straightening the optic fiber within the eye without increasing a length of the optic fiber within the eye.

18. The method of claim 16 further comprising:

straightening the optic fiber within the eye without decreasing a length of the optic fiber within the eye.
