Summary
This study evaluated a 3D-printed simulator for aneurysm clipping training. Neurosurgeons found the low-cost model realistic and useful, indicating its potential as an effective educational tool for surgical skills development.
Area of Science:
- Neurosurgery
- Medical Education
- Biomedical Engineering
Background:
- Traditional aneurysm clipping practice faces challenges.
- Surgical simulators offer a potential alternative for training.
- A reusable, low-cost 3D-printed simulator was developed for aneurysm clipping.
Purpose of the Study:
- To evaluate the face and content validity of a 3D-printed aneurysm clipping simulator.
- To assess the simulator's realism and usefulness in surgical training.
- To compare resident feedback based on experience level.
Main Methods:
- Thirty-two neurosurgery residents used the 3D-printed simulator for craniotomy and aneurysm clipping.
- A survey with Likert scale and open-ended questions assessed model validity and user experience.
- Statistical analysis included descriptive statistics, independent sample t-tests, and Confirmatory Factor Analysis (CFA).
Main Results:
- The 3D-printed simulator demonstrated good face and content validity.
- Confirmatory Factor Analysis confirmed a reliable 10-item scale (Cronbach's alpha = 0.941).
- Residents generally found the simulator realistic and useful for training.
Conclusions:
- The developed 3D-printed simulator is a valid and reliable tool for aneurysm clipping training.
- Its low cost and reusability make it an accessible educational resource.
- The simulator shows promise for enhancing neurosurgical skills acquisition.
