Area of Science:

  • Medical Robotics
  • Surgical Navigation
  • Augmented Reality

Background:

  • Robot-assisted surgery (RAS) is advancing, with augmented reality (AR) offering potential for improved surgeon visualization.
  • Intraoperative bleeding from instrument-vessel collisions is a significant risk in RAS.

Purpose of the Study:

  • To develop and evaluate a markerless AR framework to enhance safety in RAS.
  • To prevent collisions between surgical instruments and delicate blood vessels, thereby reducing bleeding risk.

Main Methods:

  • Comparison of advanced stereo reconstruction and segmentation networks for 3D blood vessel reconstruction.
  • Registration of reconstructed vessels with pre-operative models.
  • Implementation of minimum distance detection between instruments and blood vessels.
  • Emulation of robot-assisted lymphadenectomy on the da Vinci Research Kit with human subjects.

Main Results:

  • The proposed AR framework effectively guided users to avoid collisions with blood vessels.
  • No significant extra cognitive load was introduced to the users.
  • The system demonstrated usability in a simulated surgical environment.

Conclusions:

  • The markerless AR framework successfully enhances safety in robot-assisted surgery by preventing instrument-vessel collisions.
  • This flexible framework integrates AR into medical robotic platforms to improve surgical safety.
