When I first saw archelis, I thought it's a robot. But its joints could move freely, so my feeling of hesitation completely disappeared. It was surprising that I could walk without any restrictions. I felt like I was extremely free. There is always a potential fear of falling backward in the semi-fixed condition. But, there's nothing like that for archelis. It is very stable. Our surgical operations sometimes last for 8-12 hours. In the case of archelis, we can mostly be in the sitting posture. So, I think the fatigue of standing for 12 hours and sitting for 12 hours is totally different.

Absolutely easy!! Really. I used it when I was a surgical assistant and a scopist, and it was very stable.

I have lower back pain and always wear a corset during operations. But if I can sit down, the burden on my lower back becomes much less. I can be in a sitting posture, so the overall stability is significant.

And of course, I can walk, so I think it's an advantage that I can easily switch from an surgery assistant to a scopist.

For the first time I sat down, I felt like weightless and it was easy and comfortable. The doctor looking at me nearby said "You have a quite relaxing face like taking a bath". As I can come very close to the operating table, I can make a lot of fine adjustments and that makes it quite diffent from just sitting on the chair.

In laparoscopic surgery that requires precise movements of the forceps with a few millimeters, the "stability of the trunk" greatly affects the stability of the operation. Thanks to archelis which enables us to repeat "walking" and "sitting" without giving a burden on muscles even in a half-sitting posture for long hours, I think the stable movements during operation can be improved. Furthermore, I feel a great possibility that this device can support the half-sitting posture under special environments where medical workers need to go through.

By fixing the angle of knees and supporting the bodyweight by distributing it over large areas of shins and thighs, archelis enables to reduce fatigue and maintain a stable posture. In addition, thanks to its design individually separated into each leg, it enables us to sit on freely depending on the posture.

Archelis has created a new Japanese Industrial Standard (JIS). I hope that it can be widely used in various situations in the future.
