The posterior vaginal fornix puncture model is a specialized teaching aid used in clinical teaching and skills training in obstetrics and gynecology. It is mainly used to guide medical students and clinical doctors to master the standard operating procedures of posterior vaginal fornix puncture.

This model is designed based on the real anatomical structure of the female pelvis and reproductive system. It is equipped with simulated tissues such as the uterus, vagina and rectum inside, which can simulate the real touch and puncture resistance. Trainees can repeatedly practice the entire process of vaginal posterior fornix positioning, needle selection, needle insertion Angle and extraction of peritoneal effusion on the model.

Through training, the operator's spatial judgment ability and aseptic operation level can be enhanced, and they can master the skills of rapid diagnosis and treatment in gynecological acute abdomen conditions (such as ruptured ectopic pregnancy, ascites, etc.). This model is widely applied in medical college teaching, hospital resident training and skills assessment, providing a safe, intuitive and repeatable practical training platform for gynecological emergency skills training.
