Background:
- Educational simulators enhance surgical skill acquisition for students and experts.
- Medical simulators are valuable for teaching complex, high-risk procedures like external ventricular drain placement.
Purpose of the Study:
- To develop a cost-effective, patient-derived medical simulacrum for cerebral lateral ventriculostomy.
- To create a realistic training tool for a critical neurosurgical procedure.
Main Methods:
- Utilized elastomeric and gel casting for realistic brain geometry and material properties.
- Employed 3D printing for accurate cranial dimensions.
- Developed an economical, gravity-driven pump for simulating physiological ventricular pressures.
Main Results:
- Created an accurate brain model with independent lateral cerebral ventricular chambers.
- Successfully pressurized ventricular cavities to physiological values using the developed pump.
