Steerable laser probe
A steerable laser probe may include a handle, an actuation structure of the handle, a housing tube, a wire having a pre-formed curve, and an optic fiber disposed within the housing tube and an inner bore of the handle. The housing tube may include a first housing tube portion having a first stiffness and a second housing tube portion having a second stiffness. The second stiffness may be greater than the first stiffness. A compression of the actuation structure may curve or straighten the housing tube. A decompression of the actuation structure may curve or straighten the housing tube.
1. A method for performing an ophthalmic surgical procedure comprising:
varying an amount of compression of an actuation structure of a handle wherein the handle has a handle distal end and a handle proximal end and wherein the actuation structure has a plurality of actuation arms and wherein each actuation arm of the plurality of actuation arms has an inverted actuation joint; and
aiming a distal end of an optic fiber at a first target within an eye.
2. The method of claim 1 further comprising:
increasing the amount of compression of the actuation structure.
3. The method of claim 2 further comprising:
curving the optic fiber.
4. The method of claim 3 further comprising:
curving the optic fiber at least 45 degrees.
5. The method of claim 2 further comprising:
curving a housing tube wherein the housing tube has a housing tube distal end and a housing tube proximal end.
6. The method of claim 2 further comprising:
actuating an actuation platform away from the handle distal end.
7. The method of claim 2 further comprising:
retracting an actuation platform relative to a housing tube.
8. The method of claim 2 further comprising:
retracting a wire relative to a housing tube wherein the housing tube has a housing tube distal end and a housing tube proximal end.
9. The method of claim 8 further comprising:
actuating a pre-formed curve of the wire within the housing tube.
10. The method of claim 9 further comprising:
retracting the pre-formed curve away from the housing tube distal end.
11. The method of claim 1 further comprising:
decreasing the amount of compression of the actuation structure.
12. The method of claim 11 further comprising:
straightening the optic fiber.
13. The method of claim 12 further comprising:
straightening the optic fiber at least 45 degrees.
14. The method of claim 11 further comprising:
straightening a housing tube wherein the housing tube has a housing tube distal end and a housing tube proximal end.
15. The method of claim 11 further comprising:
actuating an actuation platform away from the handle proximal end.
16. The method of claim 11 further comprising:
extending an actuation platform relative to a housing tube.
17. The method of claim 11 further comprising:
extending a wire relative to a housing tube wherein the housing tube has a housing tube distal end and a housing tube proximal end.
18. The method of claim 17 further comprising:
actuating a pre-formed curve of the wire within the housing tube.
19. The method of claim 18 further comprising:
extending the pre-formed curve towards the housing tube distal end.
20. The method of claim 1 further comprising:
performing a photocoagulation procedure.
