Background technique

Vaginal dilator, also known as vaginal dilator, is mainly used for routine examination and surgical treatment in gynecology.

Referring to accompanying drawing 1, in the prior art, a commonly used vaginal dilator includes a pair of expansion wings that cooperate with each other, and the expansion wings can extend into the vagina and are used to stretch the vagina. The head ends of the pair of expansion wings are in the shape of a duckbill, and are kept open at a certain angle by the positioning device on the vaginal dilator. The doctor can use the field of view opened by the expansion wings through the observation port located at the matching part of the expansion wings. scope for examination and surgery.

Often, the interior of the vagina needs to be illuminated during examinations and procedures to ensure a good view. External lighting fixtures may be used for lighting. However, in order to simplify the operation and improve the lighting effect, more and more people start to adopt the method of directly setting the lamps on the shade diffuser for lighting.

For example, in the Chinese patent document with the application number CN201520373579.6, a disposable vaginal dilator is disclosed, which includes an LED light embedded in the vaginal dilator and a battery for powering the LED light. The vaginal dilator mentioned in this patent is disposable and must be discarded after each use. Considering the value of the battery, lamp and dilator itself, the cost is relatively high.

For another example, in the Chinese patent document with the application number CN200910106550.0, a vaginal dilator with a lighting device is disclosed, which uses LEDs fully embedded in the inner wall of the vaginal dilator, and a battery compartment is arranged in the body of the vaginal dilator . Before actual use, take out the battery in the battery compartment, and sterilize the body of the vaginal dilator, and then put the battery in after disinfection, and start using it. However, since the battery cannot be sterilized, the unsterilized battery is likely to cause pollution in the battery compartment of the vaginal dilator or nearby parts, increasing the risk of surgery. And before the vaginal dilator is charged each time, it is necessary to unload or take out the battery and repeat the disinfection operation.
