In this paper, a remote surgery experiment, which was conducted between Japan and Korea by using the developed minimally surgical system is described. A research Internet, APII (Asia-Pacific Information Infrastructure), which consists of an optical submarine cable network, KJCN (Korea-Japan Cable Network) was used as an information transmission channel. In the experiment, a laparoscopic cholecystectomy was successfully performed on a pig. The network time-delays of robot and images were 6.5 ms and 435 ms respectively.
