The Four-step palpation, anal Examination and vaginal Examination training model is a dedicated training device for obstetrics and gynecology, emergency and nursing teaching, aiming to help trainees systematically master the core skills of obstetric examination and pelvic assessment.

The model is designed based on the real human body structure and can perform Leopold four-step palpation, supporting the determination of fetal position, fetal exposure and changes in fetal position, helping learners establish a clinical understanding of the tactile sensation in the abdomen of pregnant women. Meanwhile, its realistic perineal and vaginal structures can be used to practice vaginal examination contents such as cervical dilation degree assessment, fetal exposure height judgment, and amniotic sac state identification. The anal examination function is used to assess the progress of labor and assist in the judgment of obstetric emergencies.

This model is applicable to various scenarios such as teaching demonstrations, preclinical training, and skills assessments. It enables trainees to repeatedly practice in a risk-free environment, enhancing the accuracy and sensitivity of examination techniques, thereby strengthening obstetric assessment capabilities and clinical response levels.
