We established Kairos Co., Ltd. in February 2016 in order to make endoscopes utilizing 8K Super Hi-Vision imaging technology commercially available. Although the company was just recently established, we are the first in Japan to utilize ultra-high resolution 8K in medical devices, and this technology is state-of-the-art.
“To save as many lives as possible.” It was in 2013 that a research group of physicians and specialist/corporates in medical engineering set out to conduct animal experiments and corroborate clinical evaluations with this vision. Three years later, we succeeded in the development of a prototype of 8K endoscope (rigid), which at 450g was the smallest and lightest in the world. Its resolution is equivalent to unaided vision of 4.27. We have also established converter technologies to make 8K images three-dimensional, as well as zooming function, and the commercialization of the 8K endoscope is in sight.
Based on these results, we intend to move to manufacturing and sales.
Current endoscopes have the following issues.
With the arrival of the Kairos “8K endoscope,” the efficiency and safety of endoscopic surgeries will increase dramatically. Due to shortened operating times, the number of surgeries that can be conducted in a given period of time will increase, and the length of hospitalization will decrease due to the smaller incision and laparotomy area.
In addition to ensuring the safety and security of patients, it will also contribute to the major reduction of medical expenses overall, such as hospitalization expenses, which are increasing yearly. By disseminating 8K endoscopes from Japan to markets around the world, we are confident that we will make a contribution to the Japanese economy, escaping the current situation of the considerable excess of imports of medical devices.
We thank you in advance for your interest and support of our activities.

It weighs only 370 g. It’s light enough for an easy single hand use, which can greatly reduce physical workload of operators.
A perfectly calibrated lens adaptor brings out the best of 8K high resolution.
The anti-fogging property (patented) of this rigid endoscope and 4 times digital zoom that maintains highest image quality while zooming offer a stress-free handling, powerfully assisting surgical procedures.
7680×4320 is the resolution of 8K, which is 16 times higher than 2K. Compared to a normal human sight of 20/20, 8K is equivalent to 20/4.26 while 2K is equivalent to 20/18.7.
This device delivers ultra-high definition images, as sharp as 16 times the resolution of 2K. Finer blood and lymph vessels, nerves and 12-0 suture thread (φ1～9μm) can be clearly distinguished. It can contribute to safer and securer surgeries while shortening surgical duration.
Macro image by 8K medical camera
The borders between cancerous and healthy tissues are clearly visible. Such information can facilitate maximum preservation of healthy tissues.
With 4 times digital zoom, you can see where you want to see in the magnification you want.
12-0 suture thread (φ1～9μm）is clearly visible.
These images depict a suture being ligated to join intestinal segments. Thread’s texture and capillaries on the organ surface are clearly shown. Even the device tip looks lifelike.
The entire team members can watch the procedure on an 8K ultra-high resolution large monitor screen. It can greatly contribute to safer and more precise surgeries than more stressful loupe aided surgeries.
The device can be positioned at a certain distance without losing high image quality when zooming, providing more freedom of movement
［8K］The device can be positioned at a certain distance without losing high image quality when zooming, providing more freedom of movement
［Conventional 2K］Conventional devices require closer positioning when zooming, interfering with surgical instruments.
●Powerful and reliable assistance to surgeons can help to increase the number of surgeries
Astounding volume of visual information that 8K provides can compensate for the lack of experiences for young surgeons while providing a powerful visual support for experienced surgeons. Once a chronic shortage of surgeons is compensated for and surgical duration becomes shorter, surgery room turnover can improve along with increased number of surgeries.
●Visual record of operations is valuable for medical education
Advanced techniques and academically significant cases recorded at 8K ultra high resolution will likely be a powerful tool for medical education.
●Advanced and sophisticated medical technology can enhance the reputation of your hospital
Introducing an 8K device is an innovative step forward for your institution and shall capture the interest of medical professionals as well as patients, which can contribute to gaining higher recognition as well as standing out from other institutions.
