New anatomical simulator for pediatric neuroendoscopic practice

Area of Science:

• Neurosurgery
• Medical Simulation
• Pediatric Endoscopy

Background:

• Acquiring proficiency in neuroendoscopic procedures demands extensive training.
• Current training methods may not adequately prepare surgeons for complex operations.
• A need exists for realistic simulation tools in pediatric neurosurgery.

Purpose of the Study:

• To introduce a new pediatric neuroendoscopic simulator designed to facilitate surgical training.
• To provide a realistic and safe platform for practicing essential neuroendoscopic techniques.
• To evaluate the simulator's potential in improving surgical skills and reducing the learning curve.

Main Methods:

• Development of a simulator using Neoderma®, a synthetic thermo-retractile and thermo-sensible rubber, combined with polymers for realistic tissue properties.
• Construction of a basic module using silicon and fiberglass molds replicating pediatric cerebral ventricles.
• Incorporation of functionalities for practicing ventricular navigation, third ventriculostomy, choroid plexus cauterization, and tumor resection with simulated bleeding.

Main Results:

• The simulator accurately replicates the textures, consistencies, and mechanical resistances of human tissues.
• It enables practice of fundamental neuroendoscopic techniques, including navigation of key anatomical landmarks.
• Both rigid and flexible endoscopy can be performed with high fidelity to real surgical scenarios.

Conclusions:

• The developed pediatric neuroendoscopic simulator offers a realistic and risk-free training environment.
• It has the potential to significantly improve the learning curve for inexperienced neurosurgeons.
• The simulator can aid in the dissemination of advanced techniques like flexible endoscopy.
