During operation, the colposcope will produce a lighting effect through the light guide 12 to serve as a prompt. A protective part shell 22 is provided on the lower cover 2 of the colposcope. The protective part shell 22 is made of plastic and is cylindrical in shape. The protective part shell 22 is integrally formed with the lower cover 2 of the colposcope or is tightly combined with a buckle to ensure that the camera module can be protected from external liquids when working. or the invasion of dirt, a lens protective part 21 is fixed on the protective part shell 22, and the lens protective part 21 mainly plays the role of preventing liquid from penetrating into the lens and ensuring the light transmittance of the lens during use; a circuit board 5 and a camera module 6 are arranged inside the shell formed by the upper cover 1 and the lower cover 2 of the colposcope, and the circuit board 5 is fixedly installed at a preset position inside the lower cover 2 of the colposcope, usually fixed by screws or brackets, and the circuit board 5 integrates the circuit of the control button and the power management module of the camera module; the lens part of the camera module 6 is aligned with the lens protective part 21, and the shooting button 11, the light guide 12, the adjustment button 13 and the camera module 6 are all electrically connected to the circuit board 5, and the necessary power and signal transmission channels are provided through the circuit board 5.

[0037] The working principle of the vaginal inspection device of the present invention is as follows: first, the colposcope is assembled with the dilator. When the colposcope is assembled with the dilator, the positioning groove 33 and the movable buckle 34 cooperate with the groove 23 and the male buckle 24, that is, the positioning groove 33 is inserted into the groove 23. After the two are accurately connected, the movable buckle 34 is buckled on the male buckle 24 to fix the dilator and the colposcope together to ensure a stable connection between the two. When the colposcope is used, the positioning groove 33 plays a guiding and auxiliary positioning role, and the movable buckle 34 is fixed with the male buckle 23 to temporarily fix the colposcope. The positioning groove 33 and the movable buckle 34 work together to constrain the colposcope to the center of the dilator's field of view, and the shooting and video recording functions of the colposcope are not affected by the size of the dilator's gear, and a certain viewing angle can be guaranteed. The camera module 6 of the colposcope is started, and the brightness of the light guide 12 and the LED light 71 is adjusted to obtain the best lighting effect.

[0038] After assembly, the duckbill part of the expander is gently inserted into the vagina of the person to be tested. By adjusting the short handle 35, the expander can be opened, and the rotating shaft 42 can be moved in the slide groove 32 to expand the angle between the upper duckbill 31 and the lower duckbill 41, and fixed by the serrated block 36 and the serrated bar 44 for better observation or operation.

[0039] After the dilator is unfolded, the camera module 6 of the colposcope starts to collect real-time images of the inside of the vagina. The image can be enlarged or reduced or the brightness of the light source can be adjusted by adjusting the button 13 to ensure that the image is clear. The image can be observed in real time through an external display device. When you finish using it, you only need to adjust the dilator to the minimum gear and take out the dilator and the colposcope together.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
