Development of 3D Printing High-Fidelity Thyroid Fine Needle Aspiration Exam Medical Education Model to Facilitate Student Learning and Practice

Background： Thyroid nodular disorder is prevalent in Endocrine clinics, and while thyroid fine needle aspiration examination is crucial for evaluating nodules, conveying the procedure to students is challenging. The investigators propose a high-fidelity 3D model to enhance education, especially for hands-on practice. Our study aims to assess the model's education efficacy.

Study Design： This is a prospective study.

Methods： In our study, 3D scanning and 3D printing technology will be used to create the thyroid high-fidelity model. The investigators plan to choose 3D printing materials that enable the practice of thyroid fine needle aspiration produce with No.22 or No.23 needles.

Effect： The investigators hope to assist students understand the structure of thyroid and thyroid nodules better. And students will be able to practice thyroid fine needle aspiration examination with the 3D high-fidelity model. The outcome of our study may be utilized in medical schools or hospitals to facilitate student education.
