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.

To achieve the ultimate goal of “walk and sit” which seems contradictory, Archelis takes a new design approach. A crustacean-like exoskeleton makes it possible to support the body without stressing the muscles. The basic skeleton of Archelis is composed of functional shapes that are necessary and sufficient for “walk” and “sit” by eliminating superfluous structure. That concept and functional beauty have been highly acclaimed worldwide, winning numerous design awards, including the Good Design Award (2018), the Red Dot Award (2020), and the iF Design Award (2020).
