Summary

A voice-directed robotic arm enables surgeons to manage laparoscopic procedures independently, improving view stability and reducing fatigue. This technology is effective for solo-surgery and complex operations, without increasing operative time.

Area of Science:

  • Minimally Invasive Surgery
  • Robotics in Medicine
  • Surgical Technology

Background:

  • Laparoscopic surgery often requires a dedicated assistant for scope manipulation.
  • Maintaining a stable and clear view is crucial for surgical precision.
  • Current methods for scope management can be resource-intensive.

Purpose of the Study:

  • To evaluate the efficacy of a voice-directed robotic arm for scope management.
  • To assess its utility in "solo-surgery" and complex laparoscopic procedures.
  • To determine the impact on operative time and port utilization.

Main Methods:

  • A voice-controlled robotic arm system was utilized.
  • Surgeons issued commands via microphone for scope control.
  • Individualized chip cards were programmed for each user.

  • 200 laparoscopic procedures were analyzed, including gallbladder, stomach, colon, and hernia repairs.

    • Main Results:

    • The robotic arm demonstrated precise movements and flawless voice recognition in all cases.
    • Solo-surgery was successfully performed in 100 cases.
    • Complex videoscopic procedures were completed in 96 cases.
    • Operative time and port usage were comparable to conventional methods.

    Conclusions:

    • Voice-directed robotic arms can eliminate the need for surgical assistants in certain procedures.
    • Benefits include enhanced visual stability, reduced lens smearing, and prevention of surgeon fatigue.
    • The system is applicable to all surgeons performing laparoscopy in any operating theater.
