Health and welfare for all

There are many places called "remote areas" in the world, and most of these areas lack not only daily living environment but also an adequate medical system for emergencies. However, with the recent development of 5G and 6G next generation communication technologies, the possibility of telemedicine has been attracting attention. AST motors have the potential to save the lives of people around the world.

 

- "Remote regions" that is out of reach of medical care

The term " remote areas" refers to the mountainous areas and remote islands of a country or region. In many cases, due to the poor natural conditions and the difficulty of accessing the city, these areas do not have sufficient production functions and living environments for people. Such areas are not only seen as "depopulated areas" in Japan due to the declining birthrate and aging population, but also exist in many developing countries in Africa, Asia, and South America. In these areas, there is a lack of adequate living environment and medical system, and there are even cases where there is no doctor in a town. Nothing is more regrettable than not being able to save lives that could be saved. In order for people to live a good, safe, and secure life, it is necessary not only to improve the living environment but also to ensure that the people living there have access to adequate medical care.

-Potential of telemedicine 

 

Telemedicine, as the name implies, is the use of modern technology to diagnose and treat patients from a distance. Among them, telesurgery technology is being actively developed in many countries, and it has the potential to save lives by providing the best possible surgery to those who need it from a distance. In addition, with the spread of the COVID-19 in 2020, the demand for non-contact medical care is drastically increasing, and the performance of surgical support robots needs to be improved.

The "da Vinci®" from the U.S. and the "hinotori®" from Japan are typical examples of surgical assist robots. Their merits lie in both the "patient" and the "doctor". 

One of the biggest benefits to the patient is the size of the incision and the amount of blood loss during surgery. The surgical assist robot can only make a few small holes to insert the robot's machine, thus minimizing the number of cuts and blood. The amount of anesthesia can also be reduced because the operation time is shorter. These advantages also minimize the damage to the patient, resulting in faster recovery and less need for prolonged hospitalization.

 

There are also many benefits for the doctor. They can perform surgeries with 3D images that make them feel as if they are inside the patient's body, thus reducing the damage and fatigue caused by the vision compared to conventional surgeries. The robot can also perform detailed operations such as suturing and knifing at angles that are impossible for the human hand, thereby eliminating stress. In addition, all operations are provided with an anti-shake function to minimize human error during surgery.

 

As these medical devices, including robots, develop along with the 5G and 6G communication technologies, it will be possible to provide medical opportunities to people living in "remote areas". Even if there are no trained technicians in the area, they can still perform highly accurate surgeries simply by having surgical assist robots. This will be possible anywhere in the world, and it will be an opportunity to save more lives than ever before.

 

- Future medical care realized by AST motor

The AST coil used in AST motors has a large cross-sectional area, making it possible to significantly lower the electrical resistance compared to conventional motors. This allows a large current to flow at once, resulting in higher output performance and responsiveness than ever before. This performance can be applied not only to sites that require power, such as factory automation and industrial equipment but also to surgical robots that require sensitive motions.

 

Responsiveness is the "speed of reaction. For example, when you tell a robot to turn to the right, whether it takes five seconds or one second for the robot to turn right makes a big difference. Especially for surgical robots that are used in situations where human lives are at stake, even a difference of 0.1 seconds can have a completely different result. It is precise because motors are used at the critical juncture of saving a life or not, that they need to be so responsive.

→ Since the AST coil used by the AST motor has a large cross-sectional area, it can generate a lot of current at once. This has improved the speed of reaching a certain output (improved responsiveness).

The AST motor can start up much faster than the number of seconds it takes a conventional motor (using wound coils) to produce a certain output. This indicates speed of response, an evolution that is very essential for reproducing sensitive doctor's finger sensations. This is a future that can only be realized by the large cross-sectional area of the AST coil, which reduces resistance and allows a large current to flow. There are many lives that can be saved from this company that makes motors.
