Japan's first surgical robot, technological innovation in the world of medicine.
Japan is one of the world's leading producers of industrial robots, but its surgical robot
development lagged until the introduction of Medicareoid's Hinotori.
Amid rapidly progressing automation in surgical operations, the first domestically produced
surgical robot has been introduced.
Hinotori, developed by Medicareoid Corporation, is expected to cut into a market that has
been nearly monopolized by foreign companies up to now.
The new surgical robot was approved for manufacture and sale in Japan in August 2020.
More recently, in December 2022 additional robotic surgical procedures were approved
for insurance coverage.
Then, on January 10, 2023, Hinotori was awarded the Prime Minister's Prize related to the
Ministry of Economy, Trade, and Industry.
The robot is equipped with four robotic arms to replace the surgeon, who operates the robotic
arms from a remote location.
The surgeon then conducts the procedure while confirming with detailed 3D stereoscopic images.
Development of Hinotori began in 2015 by Medicareoid, a joint venture between Kawasaki
Heavy Industries and Sysmex Corporation.
Kawasaki is the industry pioneer that developed Japan's first industrial robot, and Sysmex
is a leader in medical testing and diagnostic technology.
Hinotori takes advantage of the technological capabilities of both.
Robotic surgery is expanding to an increasing number of medical departments, such as urology,
gastrointestinal surgery, and gynecology.
Including university hospitals, 28 Japanese medical facilities had introduced the robot
as of June 2022.
Six months later by December 15, 2022, 840 surgeries had been conducted with Hinotori.
From 1999 through 2022, the Da Vinci Surgical System, hereafter referred to as Da Vinci,
manufactured by the United States company Intuitive Surgical Inc., nearly monopolized the market
for surgical robots.
However, their patent expired in 2019 and many companies have entered the market since.
Hinotori is smaller and cheaper, starting at about 200 million Japanese yen, 1.56 million
03:00
US dollars, and it's gaining momentum.
Medicareoid estimated in June 2022 that it would have about 20 percent of the domestic
share within two years after sales began.
Medical procedures have progressed from the conventional laparotomy to laparoscopy, in
which the abdomen is not cut open.
Instead, instruments are inserted through the smallest possible incisions.
Laparoscopic surgery is less of a burden on the patient, as it allows for a smaller incision,
less bleeding, and faster postoperative recovery.
On the other hand, a certain level of experience and skill with surgical instruments is required.
Surgical robots have increased in automation and have become advanced systems that compensate
for the limitations of human laparoscopic surgery.
For that reason, introduction of these robots has been increasing at about 13 percent per year.
Surgical robots have especially stood out in prostate cancer surgeries.
Robot-assisted surgery surpassed the number of conventional laparoscopic surgeries in 2013,
according to a survey by the Japan Society for Endoscopic Surgery.
Robot-assisted surgeries covered by insurance were revised in December 2022 to include gastrointestinal
surgery and gynecology.
These changes have also been a driver of.
Hinotori's compact design is intended to fit the physique of the typical Japanese person,
and the robotic arm has eight joints that allow it to perform detailed work with smooth
hand-like movements.
The know-how of Kawasaki Heavy Industries, which has excelled in industrial robot technology,
is concentrated here.
An additional advantage of the robot is that it cannot get tired or suffer from shaky hands.
It is used alongside a detailed 3D image monitor, which is placed in the so-called surgical cockpit.
From there, the surgeon can perform the procedure as if operating inside the body.
For these reasons, the robot has been praised for reducing the burden on doctors compared
to conventional products, even during long surgeries.
A doctor at a Japanese university hospital who has performed over 1,000 surgeries with
the US-made DaVinci robot said, the DaVinci machinery is large.
And for a smaller Japanese person, there is the rare chance that the robot's arms come
in contact with each other.
But Hinotori solves this issue.
From the point of view of the surgeon, this is a significant improvement.
The demands on equipment used in surgeries are extremely high.
Interruptions cannot be tolerated.
Meanwhile, sufficient training is required to operate Hinotori.
At the same time, though, doctors who have already used DaVinci can easily switch to
using Hinotori because there are many points in common.
At the very least, training time can be shortened.

Japan is one of the world's leading producers of industrial robots.
But for medical robots, it has lagged behind in domestic production and has relied on imports.
Olympus Corporation and a venture company from the Tokyo Institute of Technology have
been developing surgical robots since the 2010s.
However, Medicaroid was the first to put them into practical use.
Although Medicaroid was a latecomer to the industry, it listened carefully to the needs
of surgeons in the field.
The increase in the usage of Hinotori seems to come from the fact that the product reflects
improvements and reliability.
Even more than before, the instruments at the ends of the arms can be improved and expanded
using AI analyses of how surgeons, who are equipped with data from previous surgeries,
perform operations.
In this way, the wealth of data from the advanced surgical robots can be used effectively
to comprehensively improve healthcare, and even support hospital management.
With the entry of many related manufacturers into the field, there are expectations for
further development of the domestic market.
Furthermore, work is being done to begin demonstration tests of remote surgery systems that will make
use of high-speed communication lines dedicated for this purpose.
This will connect major health systems in urban areas to regional hospitals, allowing
doctors to remotely carry out operations, by guiding and supporting robots from several
hundred kilometres away as if they were in the same room.
Hinotori is currently preparing for sales approval in the United States and Europe, where advanced
medical services are widespread.
As for the Asia-Pacific region, the company recently established a base in Singapore to
prepare for sales in the area.
It also expects to spread in this region, where economies and medical infrastructure
are growing rapidly.
Medicaroid has set a sales target of 100 billion Japanese yen, 780 million US dollars,
for its surgical robot business by the end of March 2031.
Advances in medical technology are closely related to war.
There are numerous aspects of medicine that moved from military use to civilian use.
For example, medical tape was invented during the United States Civil War in the 19th century.
Other examples include hemostatic agents, blood transfusion and delivery systems, x-rays,
prosthetic arms and legs, hearing aids, nursing and rehabilitation techniques, and more.
The surgical robot Da Vinci also has its roots in war.
It is a medical device jointly developed by an American university and the United States
Army for military medical purposes.
Ironically, the technological innovations that were developed to treat soldiers wounded
09:02
in war and to defend against biological weapons are now reflected in advances in medical technology
for the public.
