Area of Science:

  • Neurosurgery
  • Medical Simulation
  • Virtual Reality Training

Background:

  • Surgical treatment of cerebral aneurysms is decreasing, while complexity is increasing.
  • There is a need for advanced simulation tools for neurosurgical education.
  • Training future neurosurgeons in aneurysm clipping techniques is crucial.

Purpose of the Study:

  • To develop a novel haptic-based virtual reality simulator for aneurysm clipping.
  • To evaluate the simulator's usefulness in training neurosurgical residents.

Main Methods:

  • A real-time haptic feedback virtual reality simulator was created using the ImmersiveTouch platform.
  • A 3D immersive virtual reality environment simulated a middle cerebral artery aneurysm from CT angiography data.
  • Seventeen neurosurgery residents tested the simulator and provided feedback on its realism and utility.

Main Results:

  • Most residents found the simulator useful for preparing for real surgery and preoperative rehearsal.
  • Two-thirds felt the 3D anatomy closely resembled real operative anatomy and aided surgical approach decisions.
  • One-third reported realistic haptic feedback for aneurysm clipping simulation.

Conclusions:

  • Neurosurgery residents perceived the virtual reality simulator as a valuable training tool.
  • The simulator is particularly beneficial given the limited opportunities for residents to perform aneurysm clippings during training.
