Steerable laser probe
First Claim
1. An ophthalmic surgical instrument comprising:
- a handle having a handle distal end and a handle proximal end;
a handle base of the handle;
an actuation structure of the handle;
a plurality of actuation arms of the actuation structure;
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 wherein the shape memory sleeve is at least partially disposed in the housing sleeve;
a pre-formed angle of the shape memory sleeve;
an optic fiber having an optic fiber distal end and an optic fiber proximal end wherein the optic fiber is disposed in the shape memory sleeve;
a fixation mechanism disposed in a fixation mechanism housing of the handle wherein the fixation mechanism is configured to fix the optic fiber and the shape memory sleeve relative to the handle; 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.

Abstract
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.
