Development

Entrusted by the Tottori Prefecture Medical Device Development Support Business, “mikoto” was co-developed with Tottori University Hospital. The medical simulator robot that enabled the users to train three different procedures; tracheal intubation, endoscopy, and sputum suction, was put into production on March 2015.

With the advancement of medical treatment seen in the recent years, the procedures and operations performed by medical professionals have become much more complicated and diversified. In order to secure the quality and safety of medical techniques performed at medical, nursing, and nursing care scenes, acquisition of higher clinical skills and objective assessment have become essential for those health professionals, including students, doctors, and nurses. As a result, apart from the traditional classroom lectures, education involving practical trainings utilizing simulators has been drawing more and more attention.

In order to meet those needs, we developed a simulator with a realistic appearance, internal structure, and biological reaction to make the practical procedure as real as possible. The simulator will enable the users to repeatedly conduct trainings with a human-like touch, sense, and reaction which will ultimately improve medical techniques. It will also provide opportunities to evaluate newly developed equipment to provide more secure and safe medical care.

Behind the naming of “Mikoto”

★ “mikoto (life)” … life, a given mission ★

• ○ “A real reaction as if it has a life”
• ○ Takes position as “A person with a mission (humanoid)”
*In this case mission stands for “Hands-on experience, development of doctors” etc.
