Surgical support system

Visualization of tacit knowledge

In conventional surgery, the excellent ability to recognize anatomical structures, the ability to plan the surgical process, and the ability to make decisions during surgery have been all black boxes of a skilled surgeon.

The AI surgery support system developed by our company analyzes surgical images in real time and supports the surgeon's cognitive ability, enabling safer surgery.

Hiroki Matsuzaki



While conducting research on AI diagnosis of pathological images at the University of Tokyo graduate school, he experienced the founding stage of a medical AI startup. He led the research at the National Cancer Center Hospital East in terms of technology development. Therefore, he faced with the reality of how easy it is to get into unexpected situations in surgical operations. In addition, knowing that the quality of surgery varies greatly depending on the facility and individual, he wanted to change the current situation where people lose their lives and health due to bad luck. That’s why he founded Jmees with surgeons.
