Area of Science:

  • Robotics and Telecommunications
  • Surgical Innovation
  • Medical Technology

Background:

  • Technical limitations, primarily time delay in data transmission, hindered the development of long-distance remote surgery.
  • Previous attempts were constrained by the inability to overcome significant latency issues for real-time surgical performance.

Purpose of the Study:

  • To demonstrate the feasibility of overcoming time-delay limitations in remote surgery.
  • To validate the use of high-speed terrestrial networks for transoceanic surgical procedures.
  • To explore the potential of remote surgery for global access to surgical expertise.

Main Methods:

  • Utilized high-speed terrestrial networks, specifically asynchronous transfer mode (ATM) service, to minimize data transmission time lag.

Related Experiment Videos

  • Conducted feasibility tests involving surgeons, robotic engineers, and telecommunication specialists.
  • Successfully performed a transoceanic laparoscopic cholecystectomy on an animal model and subsequently on a human patient.

    • Main Results:

    • Achieved a mean time lag of 155 milliseconds for data and image transmission over a 14,000 km round-trip distance using ATM technology.
    • Demonstrated the safe execution of a complex surgical procedure (laparoscopic cholecystectomy) remotely.
    • Confirmed that ATM networks significantly reduce latency compared to satellite connections.

    Conclusions:

    • High-speed ATM networks enable the practical realization of remote surgery across vast distances, overcoming critical time-delay barriers.
    • Tele-operated surgery holds significant potential for improving access to specialized surgical care in remote areas and enhancing surgical training globally.
    • Widespread implementation requires addressing challenges such as network availability, cost, ethical considerations, and legal jurisdictions.
