Area of Science:

  • Minimally Invasive Surgery
  • Robotics in Medicine
  • Medical Imaging and Visualization

Background:

  • Radiofrequency (RF) ablation is an alternative to hepatic resection for liver tumors.
  • Accurate RF needle insertion is challenging due to hand-eye coordination and navigation difficulties.

Purpose of the Study:

  • To propose a cooperative surgical robot system for robot-assisted percutaneous treatment of liver tumors.
  • To integrate augmented reality (AR) visual guidance, surgeon experience, and robotic accuracy.
  • To enable natural hand gesture interaction for controlling the AR system and surgical robot.

Main Methods:

  • Development of a projector-based AR environment overlaid on the patient for displaying surgical information.
  • Implementation of a mobile surgical robot system for executing RF needle insertion plans.
  • Utilizing natural hand gestures for intuitive control of the AR system and robot.

Main Results:

  • The system was evaluated on a mannequin model.
  • Hand gesture guidance effectively controlled the surgical robot.
  • Robot-assisted implementation significantly improved needle insertion accuracy.

Conclusions:

  • The proposed human-robot cooperative mechanism is a promising approach for precise transcutaneous ablation therapy.
  • Integration of AR, hand gestures, and robotic systems enhances surgical precision and control.
