Sayaka The Next Generation
“Battery Free” Capsule Endoscope
RF
SYSTEM lab. (RF Co., Ltd. located in
Nagano, Japan) is now announcing the
concept and development of the next
generation capsule endoscope, “Sayaka”.
SAYAKA supersedes the basic
technology of NORIKA3, the first
"battery-free endoscopic capsule"
announced to the market on December
2001. SAYAKA is the future of
endoscopy.
Advantage
of Capsule Endoscope
The practice of conventional
endoscopy requires expanding the
gastric walls to view the affected
area. In order to do so, the
gastrointestinal tract must be
either directly pressurized by air,
or use the endoscope mounted
"balloon method". These methods can
be an uncomfortable experience for
patients despite being performed
with anesthesia. Without preforming
this procedure, doctors are unable
to properly diagnose conditions of
the gastrointestinal tract. Due to
the procedures required for
conventional endoscopy, capsule
endoscopy is rapidly becoming the
viable solution for both doctors and
patients. Capsule endoscopes greatly
contribute to the diagnosis of the
gastrointestinal tract. With both
wireless capabilities and superior
picture quality, capsule endoscopy
gives doctors much more freedom then
ever before. The wider use of a
capsule endoscope, not only can make
a patients' visit much more
comfortable, but also lowers
examination costs and offers
patients emphasis for proper
treatment. Finally, capsule
endoscopes are designed to be
disposable after the use, which
eliminates any possibility of
in-hospital infection that can be
assosciated with conventional
endoscopy.
Problems
of Current Capsule Endoscope
An endoscopic capsule is
equipped with a lens and image
sensor in a moving direction. The
lens should be a wide-angle type to
capture as much of the
gastrointestinal tract as it can.
However a wide-angle lens has an
inherent fault; not capturing a full
clear image because of the distinct
characterics of distorting
peripheral vision. We would be not
able to achieve the fulfilled
requirements of capsule endoscopy
without overcoming this big problem.
Our goal was: “To capture the
whole gastrointestinal tract
completely and provide both a clear
and high-quality resolution image
for practical diagnosis” It would
be against our corporate ethics to
continue capsule endoscopy with the
knowledge of the exsisting fault of
current capsule endoscopes. This
merely imposes unnecessary burden to
both doctors and patients
What is “Sayaka”, the
next generation capsule endoscope?
Sayaka is a new-type
capsule endoscope simply designed
for the purpose of capturing images
of whole inner surface of the long
digestive tract.
