Abstract

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.

Claims

1. A laser probe comprising:

a handle having a handle distal end and a handle proximal end;

an actuation control mount having an actuation control mount distal end and an actuation control mount proximal end wherein the actuation control mount is disposed in a handle inner portion of the handle;

an actuation control having an actuation control distal end, an actuation control proximal end, an actuation control anterior end, and an actuation control posterior end wherein the actuation control is disposed in the actuation control mount;

an actuation chamber of the actuation control;

a cable housing of the actuation control;

a handle end cap of the handle;

a handle base of the handle having a handle end cap interface wherein the handle end cap interface is configured to interface with a portion of the handle end cap;

an auto-fixing component having an auto-fixing component distal end and an auto-fixing component proximal end wherein the auto-fixing component is disposed in an auto-fixing component housing of the handle wherein the auto-fixing component is configured to temporarily fix the actuation control in a rotational position by a magnetic force;

a single flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end wherein the flexible housing tube is disposed in a flexible housing tube housing of the handle;

an optic fiber having an optic fiber distal end and an optic fiber proximal end wherein the optic fiber is disposed in the flexible housing tube, the handle inner portion, and the actuation chamber; and

a cable having a cable distal end and a cable proximal end wherein the cable is disposed in the flexible housing tube, the handle inner portion, and the cable housing and wherein a first portion of the cable is fixed in the flexible housing tube and wherein a second portion of the cable is fixed in the cable housing and wherein a rotation of the actuation control in a first direction is configured to curve the optic fiber.

2. The laser probe of claim 1 wherein the rotation of the actuation control in the first direction is configured to curve the optic fiber at least 45 degrees.

3. The laser probe of claim 1 wherein the rotation of the actuation control in the first direction is configured to curve the flexible housing tube.

4. The laser probe of claim 1 wherein a rotation of the actuation control in a second direction is configured to straighten the optic fiber.

5. The laser probe of claim 4 wherein the rotation of the actuation control in the second direction is configured to straighten the flexible housing tube.

6. The laser probe of claim 1 wherein the flexible housing tube is manufactured from nitinol.

7. The laser probe of claim 1 further comprising:

a light source interface configured to interface with the optic fiber proximal end.

8. The laser probe of claim 7 wherein the light source interface is an SMA connector.

17. The laser probe of claim 1 further comprising:

a buffer of the optic fiber.

18. The laser probe of claim 17 wherein the buffer is a polyimide buffer.

9. A laser probe comprising:

a handle having a handle distal end and a handle proximal end;

an actuation control mount having an actuation control mount distal end and an actuation control mount proximal end wherein the actuation control mount is disposed in a handle inner portion of the handle;

an actuation control having an actuation control distal end, an actuation control proximal end, an actuation control anterior end, and an actuation control posterior end wherein the actuation control is disposed in the actuation control mount;

an actuation chamber of the actuation control;

a cable housing of the actuation control;

a handle end cap of the handle;

a handle base of the handle having a handle end cap interface wherein the handle end cap interface is configured to interface with a portion of the handle end cap;

an auto-fixing component having an auto-fixing component distal end and an auto-fixing component proximal end wherein the auto-fixing component is disposed in an auto-fixing component housing of the handle wherein the auto-fixing component is configured to temporarily fix the actuation control in a rotational position by a magnetic force;

a single flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end wherein the flexible housing tube is disposed in a flexible housing tube housing of the handle;

an optic fiber having an optic fiber distal end and an optic fiber proximal end wherein the optic fiber is disposed in the flexible housing tube, the handle inner portion, and the actuation chamber; and

a cable having a cable distal end and a cable proximal end wherein the cable is disposed in the flexible housing tube, the handle inner portion, and the cable housing and wherein a first portion of the cable is fixed in the flexible housing tube and wherein a second portion of the cable is fixed in the cable housing and wherein a rotation of the actuation control in a first direction is configured to straighten the optic fiber.

10. The laser probe of claim 9 wherein the rotation of the actuation control in the first direction is configured to straighten the optic fiber at least 45 degrees.

11. The laser probe of claim 9 wherein the rotation of the actuation control in the first direction is configured to straighten the flexible housing tube.

12. The laser probe of claim 9 wherein a rotation of the actuation control in a second direction is configured to curve the optic fiber.

13. The laser probe of claim 12 wherein the rotation of the actuation control in the second direction is configured to curve the flexible housing tube.

14. The laser probe of claim 9 wherein the flexible housing tube is manufactured from nitinol.

15. The laser probe of claim 9 further comprising:

a light source interface configured to interface with the optic fiber proximal end.

16. The laser probe of claim 15 wherein the light source interface is an SMA connector.

19. The laser probe of claim 9 further comprising:

a buffer of the optic fiber.

20. The laser probe of claim 19 wherein the buffer is a polyimide buffer.
