[0030] The implementation principle of the cervical cancer staging model demonstration aid is as follows: when the device needs to be used, first move the device to the designated position through the handle 2, then connect the device and the external power supply through the wire 24, and then start the motor 61. The output end of the motor 61 drives the first shaft 5 to rotate, the first shaft 5 drives the second sprocket 15 and the first chain 17 to run, the first chain 17 drives the first rotating rod 14 on one side of the first sprocket 16 to rotate, the first rotating rod 14 drives the first gear 18 to rotate, and the first gear 18 meshes with the rack 20 to make the first shaft 5 drive the cover plate 7 to open, and also make the first gear 18 drive the mounting plate 19 to move out of the device.

When demonstration is needed, the device is powered on, so the control panel 41 can be operated. When the early stage of cervical cancer is mentioned, the light in the diseased area 30 on the cervical module 29 is controlled through the control panel 41, so that the diseased area on the cervix emits light, thereby demonstrating the area of the disease in the early stage of cervical cancer. The corresponding early cancer area on the first display frame 26 is controlled to light up through the control panel, so that the first mold 39 on the first display frame 26 emits a dim light to identify the virus spread in the early stage of cancer. Through the explanation of the rise, the brightness of the light of the two display assemblies is changed by controlling the control panel 41, so as to reflect the situation of each stage of cervical cancer, thereby assisting teaching. When the pus manifestation needs to be reflected at last, the push rod motor 53 is started, the output end of the push rod motor 53 drives the straight rod 55 to run, the straight rod 55 drives the piston 56 to run, and the pressure is changed, so that the solution 57 in the simulation box 52 is sent into the display box 54. Because the display box 54 is fixed on the cervical module 29, the pus situation at last is simulated by this method, thereby completing the demonstration work.

[0031] Embodiment two The difference between this embodiment and embodiment one is that an anti-skid pad is fixedly connected to the bottom of the device. When the device is used, first place the device at the designated position. Because the bottom of the device is fixedly connected with the anti-skid pad, the stability of the device during demonstration can be ensured, and the situation that the device slips during use can be avoided.

[0032] Example three The difference between this embodiment and example one is that a mark plate is fixedly connected on one side of the mounting plate 19, and when the device is used for demonstration, the name of the corresponding part and the possible pathological condition can be written on the mark plate, thereby enriching the teaching method and improving the teaching quality.

[0033] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
