Summary
This study introduces a novel phantom system for brain tumor surgery training. The system effectively enhances surgical planning skills and surgeon confidence in a simulated, risk-free environment.
Area of Science:
- Neurosurgery Training
- Surgical Simulation Technology
Background:
- Brain tumor surgeries demand high technical skill and complex surgeon-technology interaction.
- Current surgical education requires innovative training solutions and standardized evaluation methods.
- Phantom-based training systems offer a potential supplement to existing surgical education.
Purpose of the Study:
- To develop and evaluate a prototype phantom-based training system for neurosurgery.
- To provide standardized training for critical aspects of brain tumor surgery using real patient data.
- To assess the system's effectiveness in improving surgical planning and safety.
Main Methods:
- Developed a three-part head phantom prototype for single-use module replacement.
- Simulated surgical planning, neuronavigation system setup, and navigated craniotomy with real instruments.
- Utilized tracked instruments and predefined paths for objective training feedback.
Main Results:
- Pilot study evaluation by assistant physicians rated phantom construction and materials as "good".
- Navigated planning learning effect was rated "very good".
- The system was found to increase surgeon safety before independent patient procedures.
Conclusions:
- The phantom training system shows promise for future neurosurgeon education.
- It offers a realistic, non-risk simulation to enhance surgical skills.
- The system can bridge the gap between theoretical and practical training, benefiting surgeons and patients.
