World's Smallest! 8K Endoscope Camera
reveals vivid details beyond naked eye observation

About us

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.

  1. If you attempt to conduct treatment while observing the affected area in detail, the tip of the endoscope needs to be moved closer to the affected area, bumping into the surgical equipment and obstructing surgery.
  2. When observing the affected area in detail from close range, there is the risk of missing bleeding, etc. taking place in surrounding areas due to the restricted field of vision of the endoscope.

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.

Merit

What 8K Device can do for You and Your hospital

More freedom of movement can lead to a less risk of medical accidents

The device can be positioned at a certain distance without losing high image quality when zooming, providing more freedom of movement

●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.
