Steerable laser probe

摘要

A steerable laser probe may include a handle having a handle proximal end and a handle distal end, an actuation structure of the handle, a housing sleeve, a shape memory sleeve at least partially disposed within the housing sleeve, and an optic fiber disposed within the shape memory sleeve and within an inner bore of the handle. A compression of the actuation structure may be configured to gradually curve the optic fiber. A compression of the actuation structure may be configured to gradually straighten the optic fiber. A decompression of the actuation structure may be configured to gradually curve the optic fiber. A decompression of the actuation structure may be configured to gradually straighten the optic fiber.

1. An instrument comprising:
a handle having a handle distal end and a handle proximal end; a housing sleeve having a housing sleeve distal end and a housing sleeve proximal end; a shape memory sleeve having a shape memory sleeve distal end and a shape memory sleeve proximal end, the shape memory sleeve at least partially disposed within the housing sleeve; a pre-bent angle of the shape memory sleeve; an optic fiber having an optic fiber distal end and an optic fiber proximal end, the optic fiber disposed within an optic fiber guide of the handle and the shape memory sleeve; an actuation structure of the handle having an actuation structure distal end and an actuation structure proximal end; a plurality of actuation arms of the actuation structure, each actuation arm of the plurality of actuation arms having at least one extension mechanism; and an actuation cone having an actuation cone distal end and an actuation cone proximal end, the actuation cone at least partially disposed within the actuation structure wherein a compression of the actuation structure is configured to retract the actuation cone into the actuation structure and gradually curve the optic fiber.
