STEERABLE LASER PROBE

摘要

A steerable laser probe may include a handle having a handle distal end and a handle proximal end, a housing sleeve disposed in an inner bore of the handle configured to project a distance from the handle distal end, an optic fiber disposed in the housing sleeve, a shape memory sleeve disposed over a distal end of the optic fiber, and a light source configured to connect to a proximal end of the optic fiber. The shape memory sleeve may be configured to curve the distal end of the optic fiber at an angle, e.g., 90 degrees, when the shape memory sleeve is not contained within the housing sleeve.

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; a nosecone having a nosecone distal end and a nosecone proximal end; an actuation guide of the nosecone; an actuation mechanism having an actuation mechanism distal end and an actuation mechanism proximal end; an actuation guide interface of the actuation mechanism configured to interface with the actuation guide; a housing sleeve having a housing sleeve distal end and a housing sleeve proximal end wherein the housing sleeve is disposed in the nosecone; 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 in the housing sleeve; a pre-bent angle of the shape memory sleeve; and an optic fiber having an optic fiber distal end and an optic fiber proximal end, the optic fiber disposed in the shape memory sleeve and in an inner bore of the handle.
