Patent Images
1. 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.

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.
