1. An instrument comprising:
- a handle having a handle distal end and a handle proximal end;
an actuation structure of the handle, the actuation structure having an actuation ring;
a plurality of actuation arms of the actuation structure, each actuation arm of the plurality of actuation arms having at least one extension mechanism;
an outer nosecone having an outer nosecone distal end and an outer nosecone proximal end, the outer nosecone proximal end disposed within the actuation ring;
a piston tube having a piston tube distal end and a piston tube proximal end, the piston tube distal end disposed within the outer nosecone;
an inner nosecone having an inner nosecone distal end and an inner nosecone proximal end, the inner nosecone disposed within the outer nosecone wherein the inner nosecone distal end extends a distance from the outer nosecone distal end;
an inner bore of the handle;
a piston tube housing of the handle, the piston tube proximal end disposed within the piston tube housing of the handle;
a single flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end, the flexible housing tube having dimensions configured for performing ophthalmic microsurgical procedures through a cannula; and
an optic fiber disposed in the inner bore of the handle, the flexible housing tube, the piston tube, the outer nosecone, and the inner nosecone.

Abstract
A steerable laser probe may include a handle having a handle distal end and a handle proximal end, an actuation structure of the handle, a flexible housing tube having a flexible housing tube distal end and a flexible housing tube proximal end, and an optic fiber disposed within an inner bore of the handle and the flexible housing tube. A compression of the actuation structure may cause the optic fiber to gradually curve. A decompression of the actuation structure may cause the optic fiber to gradually straighten.
