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.

Specular, ultrasonic, piezoelectric, detection devices provide real-time, analytical, edge finding in tissues during tumor surgery. Piezoelectric probe sensors at high frequencies (e.g., 10 to 100 MHz) characterize microstructure of cells and tissues. Through-transmission or specular reflection enables nondestructive testing in real time. Peak density analysis in power spectra, second-order spectrum analysis measuring the slope of the Fourier transform of the power spectrum, artificial intelligence pattern recognition, and modeling interpret the results. Model-based data analysis may compare experimental data with a computer simulation. Such comparisons may be based upon pattern classifications, including principal component analysis (PCA). Combining the above detection devices and analytical methods provides speed, accuracy, simplicity, and nondestructive mechanisms that militate for reliable, real-time diagnosis of tumor margins, tissue pathology, cell phenotypes, and molecular subtypes.
