Summary
This study developed an affordable, 3D-printed trachea simulator for cricothyroidotomy training. The realistic and accurate model enhances emergency airway surgery simulation for medical professionals.
Area of Science:
- Medical Simulation
- 3D Printing Technology
- Anatomical Modeling
Background:
- Current cricothyroidotomy simulators lack anatomical accuracy and are costly.
- This limits realistic training experiences for emergency airway procedures.
Purpose of the Study:
- To develop an inexpensive, anatomically accurate trachea simulator using 3D printing.
- To improve accessibility and reproducibility of emergency cricothyroidotomy training.
Main Methods:
- Utilized 3D modeling software and a desktop 3D printer to create a trachea model.
- Incorporated anatomical dimensions and expert feedback for accuracy.
- Simulated tracheal ligaments and skin for enhanced realism.
Main Results:
- Successfully designed and manufactured a low-cost ($1.70 CAD) 3D-printed trachea model.
- The model is anatomically accurate, flexible, and durable, printable in under three hours.
- The simulator effectively replicates landmarks for emergency cricothyroidotomy.
Conclusions:
- The 3D-printed trachea model offers a cost-effective, high-fidelity solution for medical simulation.
- This novel simulator enhances emergency airway surgery training, particularly for educators with limited resources.
