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
An ophthalmic 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 has a plurality of actuation arms and wherein each actuation arm of the plurality of actuation arms has an inverted actuation joint;
- a housing tube having a housing tube distal end and a housing tube proximal end wherein the housing tube proximal end is disposed in an optic fiber guide of the handle;
- a first housing tube portion of the housing tube having a first stiffness;
- a plurality of slits of the first housing tube portion;
- a second housing tube portion of the housing tube 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 wherein the optic fiber is disposed in the handle and the housing tube and wherein a compression of the actuation structure is configured to curve the housing tube.
