Area of Science:

  • Medical Simulation
  • Surgical Training Technologies
  • Virtual Reality Applications

Background:

  • Endoscopic sinus and skull-base surgery require extensive training.
  • Traditional training methods may lack realism and patient-specific anatomical detail.
  • Developing advanced simulators is crucial for improving surgical proficiency.

Purpose of the Study:

  • To introduce a novel virtual reality (VR) haptic simulator for endoscopic sinus and skull-base surgery training.
  • To incorporate realistic surgical instruments and patient-specific 3D-printed anatomical models.
  • To facilitate realistic surgical motion and enhance trainee skill acquisition.

Main Methods:

  • Development of a VR haptic simulator integrating a main body, monitor, endoscope, two haptic devices, and pedals.
  • Utilizing an electromagnetic sensor for precise endoscope tracking.
  • Creating exchangeable patient-specific external nostril and caudal septum models using 3D printing and human-tissue-mimicking materials.
  • Employing Unity 3D for graphics rendering and the SOFA physics engine for realistic interactions.

Main Results:

  • The VR haptic simulator supports training for basic endoscopic sinus surgeries, including maxillary sinus antrostomy, ethmoidectomy, and frontostomy.
  • It also enables practice of endoscopic endonasal transsphenoidal and transclival approaches.
  • The simulator provides a realistic platform for diverse surgical tasks.

Conclusions:

  • VR haptic simulators significantly improve surgical trainees' skills and confidence through varied practice.
  • The proposed simulator integrates novel technologies for a highly realistic training environment.
  • This advanced simulator is well-suited for endoscopic sinus and skull-base surgical education.
