Radical hysterectomy, i.e., a surgical method for treating cervical carcinoma, is put forward by Wertheim over 100 years before, becomes a classic of surgical treatment of cervical carcinoma, contributes to increasing the five-year survival rate of a patient suffering from cervical carcinoma by 80-90 percent, but has the defects of great damages, the occurrence rate of 70-85 percent of postoperative urinary bladder dysfunction, and influence on the postoperative life. Laparoscope cervical carcinoma radical-curing nerve-sparing surgery can be used for improving the urinary bladder function after a cervical carcinoma surgery and protecting hypogastric nerves, and is an important surgical link for protecting urinary bladder and rectum functions. Through simulation teaching, doctors are taught with a safe and effective method, students can contact ''patients'' by means of surgical skills before starting a surgery, and damages to nerves in the true surgery are avoided. In the simulation teaching, surgical instruments are needed, but above all model ''patients'' are needed. An anatomic plane and a repeatedly-operated simulation surgery model are taken as the teaching bases of surgeries, so that the students grasp anatomic positions and surgical separation skills. A surgical planar model disclosed by the invention promotes further development of surgery simulation teaching all over the world.
