Tmsuk R&D Inc., a medical venture firm based in Tottori Prefecture, Japan, has teamed up with the Tottori University Hospital to create what could very well be the future of medical simulations: a 3D printed robot named Mikoto.

Mikoto, which is the Japanese word for “life,” is an extremely lifelike medical simulation robot that was specifically developed to help train young doctors, medical students, and emergency care workers. Not only does the 3D printed robot look and feel real, it is also equipped with special sensors that allow it to give real-time feedback to trainees—in the form of saying “ouch” and gagging.

At first glance, it's easy to mistake the robot for a real boy, as all of its features are uncannily lifelike. Even its interiors are anatomically accurate, as its tongue, esophagus, and windpipe were all based on a patient’s actual organs. In making the simulation robot, the Tmsuk team transformed digital images of the patient’s organs into 3D printed models.

As we’ve seen, the medical sector is turning increasingly towards realistic 3D printed models to train surgeons and simulate medical procedures. In Japan, where most medical learning is still done through textbooks, simulations are also gaining in popularity, as they offer hands-on experience and training, though the simulation models are still relatively limited in their scope.

That is, while many medical schools and hospitals are equipped with simulation centers, many of the current training devices and “dolls” are much more rigid than real patients, which creates a discrepancy between what doctors are trained to do and what they actually do when they encounter a real patient.

Dr. Toshiya Nakano, a neurologist at the University of Tottori’s faculty of medicine, added: “Young doctors used to learn the ropes gradually by observing senior doctors at work and then trying their hand at operating on actual patients. Such styles of training are no longer acceptable. Ensuring patient safety is a top concern.”

The new Mikoto robot thus marks a remarkable step forward for medical simulation equipment. Mikoto is not designed for all types of simulations, however, but is built for three main procedures: endotracheal intubation (a process wherein a patient’s airway is forced open by a tube in the windpipe), gastrointestinal endoscopy (where internal organs are checked using a flexible fiber-optic camera tube), and sputum suctioning.

As mentioned, Mikoto is equipped with various sensors which can alert users if they are putting too much pressure on the robot, or if they are choking it. At the end of the simulation, the 3D printed robot also issues a score for the simulation, which is based on data obtained through the sensors as well as the length of the procedure.

Tottori Prefecture

Tottori Prefecture, where the simulation robot is being developed, is known primarily for its sandy hills and landscape. In an effort to boost its economy and to become known as a hub for medical technology, Tottori has been investing in and focusing on the development of innovative medical devices, including Mikoto, mouthpieces for dental surgery, and an adjustable laryngoscope.

“The stereotypical views of Tottori have been that it’s a place of hot springs, sand dunes and crabs—a remote place,” said Hiroya Kitano, a Tottori University director. “Many people think it has nothing to do with cutting-edge medical technology.”

By promoting partnerships between local businesses and its academic community, the prefecture is hopeful it can not only put itself on the technological map, but offer some much needed breakthroughs. If Mikoto is any indication, we have to say it’s off to a good start.
