The role of the comprehensive skills training model for manual delivery lies in providing a controllable and intuitive practical platform for obstetrics and gynecology teaching and clinical skills training.

Through the hand-cranking device, teachers can simulate the labor mechanisms such as the descent, internal rotation, flexion and delivery of the fetus in the birth canal, enabling trainees to clearly understand the dynamic changes of each stage of labor. The model can repeatedly demonstrate normal delivery and common abnormal conditions, facilitating the training of operational skills such as perineal protection, midwifery cooperation, and emergency handling.

Compared with simple theoretical explanations, the hand-crank-operated delivery model enhances the sense of participation and depth of understanding in learning, helps trainees establish correct delivery assessment and operation ideas, improves practical midwifery abilities, and at the same time avoids risks to pregnant and postpartum women. It plays an important role in teaching and training.
