Steerable laser probe

摘要

A steerable laser probe may include a handle, an actuation structure of the handle, a housing tube, a flexible tube, an optic fiber, and a wire having a pre-formed curve. The flexible tube may be disposed within the housing tube wherein a distal end of the flexible tube projects out from a distal end of the housing tube. The optic fiber may be disposed within an inner bore of the handle, the housing tube, and the flexible tube. The wire may be disposed within the housing tube.

1. An instrument comprising:
a handle having a handle distal end and a handle proximal end; an actuation structure of the handle; a plurality of actuation arms of the actuation structure; an actuation platform of the handle, the actuation platform disposed within the actuation structure; an extension mechanism of each actuation arm of the plurality of actuation arms; an inverted actuation joint of each actuation arm of the plurality of actuation arms; a housing tube having a housing tube distal end and a housing tube proximal end; a flexible tube having a flexible tube distal end and a flexible tube proximal end, the flexible tube proximal end disposed in the housing tube and the flexible tube distal extending from the housing tube distal end; an optic fiber disposed within an inner bore of the handle, the housing tube, and the flexible tube; and a wire having a pre-formed curve, the wire disposed within a portion of the handle and the housing tube wherein a decompression of the actuation structure is configured to reduce a force applied to the actuation platform by at least one inverted actuation joint and curve the optic fiber.
