Query: Light in the Larynx: a Miniaturized Robotic Optical Fiber for In-office
  Laser Surgery of the Vocal Folds   This letter reports the design, construction, and experimental validation of
a novel hand-held robot for in-office laser surgery of the vocal folds.
In-office endoscopic laser surgery is an emerging trend in Laryngology: It
promises to deliver the same patient outcomes of traditional surgical treatment
(i.e., in the operating room), at a fraction of the cost. Unfortunately, office
procedures can be challenging to perform; the optical fibers used for laser
delivery can only emit light forward in a line-of-sight fashion, which severely
limits anatomical access. The robot we present in this letter aims to overcome
these challenges. The end effector of the robot is a steerable laser fiber,
created through the combination of a thin optical fiber (0.225 mm) with a
tendon-actuated Nickel-Titanium notched sheath that provides bending. This
device can be seamlessly used with most commercially available endoscopes, as
it is sufficiently small (1.1 mm) to pass through a working channel. To control
the fiber, we propose a compact actuation unit that can be mounted on top of
the endoscope handle, so that, during a procedure, the operating physician can
operate both the endoscope and the steerable fiber with a single hand. We
report simulation and phantom experiments demonstrating that the proposed
device substantially enhances surgical access compared to current clinical
fibers.
