AI Simulations: A New Approach to Train Neurosurgeons

JJohn September 6, 2023 1:03 PM

Artificial intelligence (AI) is reshaping the world of neurosurgery training, offering novice surgeons an opportunity to practice on virtual brain matter before operating on actual patients. Driven by pioneering work at McGill University, AI-powered simulations aim to significantly enhance the skills of neurosurgeons, potentially reducing patient risks and improving surgical outcomes.

AI-powered simulation for neurosurgery training

At the Neurological Simulation Center in McGill University, artificial intelligence is being harnessed to create a lifelike experience of neurosurgery. Here, surgical residents can 'operate' on virtual tumors, mimicking the complexity and delicacy of real-life brain operations. This innovative approach allows for a safe, risk-free environment where surgeons can master their skills without compromising patient safety. The project, the brainchild of retired brain surgeon Rolando Del Maestro, strives to revolutionize the traditional training methods in neurosurgery.

Real-time feedback with NeuroVR simulator

The NeuroVR simulator, the heart of the training program, offers a realistic depiction of the brain on a computer screen. Trainees use styluses attached to swivels, representing the two essential tools in a neurosurgical procedure: a suction device and an electrocautery. The simulator provides real-time feedback, guiding the trainees on how to improve their finesse and technique. The simulator's AI system identifies and ranks around 5,000 discrete manual movements, transforming complex procedures into a series of manageable, trainable tasks.

While the NeuroVR simulator has succeeded in enhancing skill acquisition, it does face certain limitations. One major challenge is the replication of 'haptic feedback' - the tactile feel of different kinds of tissues under surgical tools. The diversity of brain tumors, each with its unique characteristics, is another aspect hard to capture in simulations. Additionally, the psychological pressure associated with operating on a living person's brain is a factor that is hard to simulate.

NeuroVR: A learning tool for all levels

The NeuroVR simulator serves as a valuable tool for both new residents and seasoned surgeons. For junior residents, it provides a risk-free environment to learn the basics of neurosurgery. Meanwhile, experienced surgeons can utilize the simulator as a refresher tool, especially before undertaking rare or complex procedures. Despite its limitations, the simulator represents a significant advancement in neurosurgery training.

Dr. Del Maestro, the man behind the NeuroVR simulator, is hopeful about its potential in enhancing the medical profession. His research suggests that the peak performance for surgeons, which typically hits between the ages of 45 and 55, could be extended with regular use of the machine. For newcomers to the field, the simulator could also significantly reduce the training period, expediting their readiness to operate on actual patients.
