Reusable Low-Cost 3D Training Model for Aneurysm Clipping

Area of Science:

• Neurosurgery
• Medical Education
• Biomedical Engineering

Background:

• Traditional aneurysm clipping training faces challenges from new endovascular techniques.
• Existing simulators can be expensive, complex, or lack realism.
• A novel, reusable, low-cost 3D-printed training model for aneurysm clipping was developed.

Purpose of the Study:

• To evaluate the effectiveness and realism of a newly developed 3D-printed aneurysm clipping simulator.
• To assess the model's suitability for neurosurgery residents of varying experience levels.
• To determine the cost-effectiveness of the training model.

Main Methods:

• A 3D-printed simulator replicating cranial anatomy and aneurysms was created.
• Thirty-two neurosurgery residents (Junior and Senior groups) used the model for simulated aneurysm clipping.
• Resident feedback was collected via surveys, and data were analyzed using statistical methods.

Main Results:

• The simulator demonstrated high face and content validity, receiving positive resident feedback.
• No significant differences in perceived utility were found between Junior and Senior residents.
• The model proved highly reliable and cost-effective, with 97% of users finding it useful.

Conclusions:

• The 3D-printed aneurysm clipping simulator offers a realistic, adaptable, sustainable, and low-cost training solution.
• The model can be effectively integrated into neurosurgery residency programs and professional development meetings.
• This innovative tool addresses the need for improved surgical training in aneurysm clipping.
