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.

Compared with the prior poly(ε-caprolactone) low temperature thermoplastic material, the present low temperature thermoplastic material has a smaller shrinking force and a better fastening intensity, is more comfortable and can be stretched more uniformly after moulding. Therefore, the material is suitable for hospital and other radiotherapy institution and can be used compatibly with three-dimensional conformal radiotherapy equipments in tumor surgery.

The present invention relates to a fluorescence navigation system used in tumor surgery, which belongs to clinical medicine surgery. The present invention solves problems existing in the surgical excision operation process of tumors that tumor boundaries are difficult to identify, remnant tumor tissue is difficult to recognize, and tumor metastasis lymph glands are difficult to track. The fluorescence navigation system used in tumor surgery is characterized in that the system comprises a biofluorescence excitation light source, a light guide system, a specificity targeted marking fluorescent material, a video camera and an image display and processing device connected with the video camera. The present invention provides fluorescence navigation concept for tumor surgery based on the priorart. When physicians identify tumor boundaries, recognize remnant tumor tissue, and track tumor metastasis lymph glands with a fluorescence observing mirror or a camera display system, tumor tissue is thoroughly excited, operation therapeutic effect is effectively improved, and the death rate of tumor patients is reduced. The present invention makes a breakthrough in tumor surgery.
