Currently, in the medical field, Surgeon instructs the irradiation point to other health care workers, and they change the irradiation location of non-shadow lamps in their hands. Also, during surgery, to illuminate the hand in a stable, Surgeon wearing the head lights illuminate the operative field by moving their head. However, the above-mentioned behavior in prolonged surgery leads to a decrease in efficiency and concentration Therefore, as one method of solving I'm developing a headlight system that can control the light irradiation location in a hands-free. The device is intended to support the operator in laparotomy Here. I report on system overview and the prototype small biaxial headlight mechanism
