Area of Science:

  • Thoracic surgery
  • Medical simulation
  • Virtual reality applications

Background:

  • Robotic-assisted thoracic surgery (RATS) is standard for lung cancer but presents challenges in visualization and tactile feedback.
  • Minimally invasive approaches in RATS require enhanced navigation through complex pulmonary anatomy.
  • A virtual reality (VR) surgical navigation system was developed to address these challenges.

Purpose of the Study:

  • To enhance preoperative familiarization with patient-specific anatomy for RATS.
  • To improve preoperative simulation and intraoperative navigation in thoracic procedures.
  • To optimize surgical planning and execution in lung cancer treatment.

Main Methods:

  • Integration of 3D CT scan data into Perspectus VR Education software.
  • Utilization of head-mounted displays (HMDs) for interactive 3D reconstruction of pulmonary structures.
  • Real-time intraoperative guidance using 3D images displayed via Tile-Pro™ multi-display during RATS.

Main Results:

  • Precise visualization of pulmonary structures and lesion relationships was achieved.
  • Enhanced surgical safety and accuracy were demonstrated.
  • True 3D interaction with patient data facilitated effective surgical planning.

Conclusions:

  • VR simulation with HMDs provides a novel method for developing robotic surgical skills.
  • Integration with routine imaging improves preoperative planning, safety, and accuracy in anatomical resections.
  • This technology aids lesion identification in RATS, optimizing surgical outcomes.
