Novel Three-Dimensional Printed Simulators for Ultrasound-Guided Prenatal Diagnostic Procedures

Amniocentesis and chorionic villous sampling (CVS) are essential ultrasound-guided diagnostic procedures in modern obstetrics, but their declining frequency poses challenges for clinician training. We present novel 3-dimensional (3D)-printed simulators designed to train practitioners in performing these procedures under ultrasound guidance. Our models combine 3D-printed components with medical gelatin to mimic the abdomen and pelvis of a pregnant patient. Customizable inserts enable realistic simulated needle targeting practice. This standardized, reproducible, and realistic training tool offers a valuable resource for improving ultrasound-guided procedural skills.
