First Claim
Patent Images
1. An instrument comprising:
- an actuation structure having an actuation structure distal end and an actuation structure proximal end;
a nosecone;
a first link, the first link fixed to the actuation structure by a first link pin and the first link fixed to the nosecone by a second link pin;
a second link, the second link fixed to the actuation structure by a third link pin and the second link fixed to the nosecone by a fourth link pin;
a housing tube having a housing tube distal end and a housing tube proximal end;
a first housing tube portion of the housing tube, the first housing tube portion having a first stiffness;
a second housing tube portion of the housing tube, the second housing tube portion having a second stiffness wherein the second stiffness is greater than the first stiffness; and
an optic fiber having an optic fiber distal end and an optic fiber proximal end, the optic fiber disposed in the actuation structure and the housing tube.

Abstract
A steerable laser probe may include an actuation structure, a nosecone fixed to the actuation structure by one or more links and one or more link pins, a housing tube having a first housing tube portion with a first stiffness and a second housing tube portion with a second stiffness, and an optic fiber disposed in the housing tube and the actuation structure. A compression of the actuation structure may be configured to gradually curve the housing tube and the optic fiber. A decompression of the actuation structure may be configured to gradually straighten the housing tube and the optic fiber.
