STEERABLE LASER PROBE

摘要

A steerable laser probe may include a handle, and inner bore of the handle, an actuation structure of the handle, a housing tube, and an optic fiber disposed within the inner bore of the handle and the housing tube. 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 surgeon may aim the steerable laser probe by varying a rotational position of the handle and an amount of compression of the actuation structure.

主权项

1. A method comprising:
applying a compressive force to an actuation structure of a handle wherein the handle has a handle distal end and a handle proximal end; compressing the actuation structure wherein the actuation structure comprises a plurality of actuation arms and wherein each actuation arm of the plurality of actuation arms has at least one inverted actuation joint; transferring the compressive force to an actuation platform of the handle; actuating the actuation platform; retracting the actuation platform relative to a handle base of the handle; retracting the actuation platform relative to a housing tube wherein the housing tube has a housing tube distal end and a housing tube proximal end; applying a force to a portion of the housing tube; compressing the portion of the housing tube; curving the housing tube; and curving an optic fiber wherein the optic fiber has an optic fiber distal end and an optic fiber proximal end.
