This study introduces haptic navigation for robotic surgery, providing force feedback to help surgeons avoid collisions with critical areas. This method enhances surgical safety by improving spatial awareness during procedures.

Area of Science:

  • Robotics
  • Surgical Technology
  • Human-Computer Interaction

Background:

  • Current robotic surgery displays offer limited information about target tissues.
  • This limitation can hinder precise manipulation and compromise surgical safety.

Purpose of the Study:

  • To propose a novel haptic navigation method for robotic surgery.
  • To enhance surgeon awareness and prevent collisions with critical anatomical regions.
  • To develop an intuitive interface for defining 3D "untouchable" zones.

Main Methods:

  • Developed a haptic navigation system generating force feedback via a master manipulator.
  • Created a 2D interface for assigning 3D untouchable regions.
  • Conducted simulator-based experiments to evaluate the system's effectiveness.

Main Results:

  • The proposed haptic navigation method effectively guides surgeons to avoid collisions.
  • Force feedback provides crucial information about proximity to critical structures.
  • The 2D interface allows for efficient definition of 3D hazardous zones.

Conclusions:

  • Haptic navigation significantly improves the safety of robotic surgery.
  • The system enhances surgeon's ability to navigate complex surgical fields.
  • This technology holds promise for reducing intraoperative complications.
