Abstract
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.
Claims20
A steerable laser probe comprising:
- a handle having a handle distal end and a handle proximal end;
- an actuation structure of the handle having an actuation structure distal end and an actuation structure proximal end wherein the actuation structure distal end is disposed between the handle distal end and the handle proximal end and the actuation structure proximal end is disposed between the handle distal end and the handle proximal end;
- a plurality of actuation arms of the actuation structure, each actuation arm of the plurality of actuation arms having an inverted actuation joint;
- a single housing tube having a housing tube distal end and a housing tube proximal end;
- a first housing tube portion of the housing tube, the first housing tube portion having a first stiffness;
- a second housing tube portion of the housing tube, the second housing tube portion having a second stiffness wherein the second stiffness is greater than the first stiffness;
- and
- an optic fiber having an optic fiber distal end and an optic fiber proximal end, the optic fiber disposed in the housing tube and the handle wherein varying an amount of compression of the actuation structure is configured to aim the optic fiber distal end at a first target within an inner eye.
