Steerable laser probe
First Claim
1. An instrument comprising:
- a handle having a handle distal end and a handle proximal end;
a handle end cap of the handle having a handle end cap distal end and a handle end cap proximal end;
a handle base of the handle having a handle base distal end and a handle base proximal end;
an actuation control mount of the handle having an actuation control mount distal end and an actuation control mount proximal end wherein the actuation control mount distal end is disposed in the handle base and wherein the actuation control mount proximal end is disposed in the handle end cap;
an actuation control of the handle, the actuation control disposed within the actuation control mount;
a fixation pin disposed in a portion of the actuation control and the actuation control mount wherein an application of a force to a portion of the actuation control is configured to rotate the actuation control about the fixation pin;
an actuation chamber of the actuation control;
a single housing tube having a housing tube distal end and a housing tube proximal end, the housing tube having dimensions configured to perform microsurgical procedures;
a first housing tube portion of the housing tube, the first housing tube portion having a first stiffness and having a plurality of slits wherein each slit of the plurality of slits has an archa 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;
an optic fiber having an optic fiber distal end and an optic fiber proximal end, the optic fiber disposed in the housing tube, an inner portion of the handle, and the actuation chamber of the actuation control; and
a cable having a cable distal end and a cable proximal end, the cable disposed in the housing tube and the inner portion of the handle wherein the cable distal end is adjacent to the housing tube distal end and wherein a portion of the cable is fixed to a portion of the housing tube wherein a rotation of the actuation control about the fixation pin in a first direction is configured to gradually curve the optic fiber.

Abstract
A steerable laser probe may include a handle having a handle distal end and a handle proximal end, an actuation control of the handle, a housing tube having a housing tube distal end and a housing tube proximal end, a first housing tube portion having a first stiffness, a second housing tube portion having a second stiffness, an optic fiber disposed within an inner portion of the handle and the housing tube, and a cable disposed within the housing tube and the actuation control. A rotation of the actuation control may be configured to gradually curve the housing tube and the optic fiber. A rotation of the actuation control may be configured to gradually straighten the housing tube and the optic fiber.
