1. A laser probe comprising:
a handle having a handle distal end and a handle proximal end;
a piston guide of the handle;
a single piston having a piston distal end and a piston proximal end wherein the piston is disposed in the piston guide;
a housing tube guide of the handle;
a housing tube having a housing tube distal end and a housing tube proximal end wherein the housing tube is disposed in the piston, the piston guide, and the housing tube guide and wherein the housing tube is fixed in the piston and wherein the housing tube is configured to actuate within the housing tube guide;
a cable having a cable distal end and a cable proximal end wherein a first portion of the cable is fixed in the housing tube and wherein a second portion of the cable is fixed in the handle, the cable having a cable proximal loop at the cable proximal end;
a fixation pin disposed within the cable proximal loop;
a first housing tube portion of the housing tube having a first stiffness;
a plurality of apertures of the first housing tube portion;
a second housing tube portion of the housing tube 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 wherein the optic fiber is disposed in the handle, the piston, the piston guide, the housing tube guide, and the housing tube and wherein an application of a force to the piston proximal end is configured to actuate the piston within the piston guide and wherein an extension of the piston relative to the handle proximal end is configured to extend the housing tube proximal end relative to the handle proximal end and the cable and curve the optic fiber.
