Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a gynecological dilator. [0002] technical background [0003] Gynecology is one of the four main disciplines of clinical medicine, which mainly studies the etiology, pathology, diagnosis and prevention of female reproductive organ diseases. In the process of gynecological examination, vaginal expansion equipment is generally used, and the vaginal dilator is also the main equipment in this process.

AI Technical Summary

Problems solved by technology

At present, the vaginal dilators in the prior art have the following problems: only the upper and lower parts are separated to open the vagina, and the vaginal tissue on both sides of the opened vaginal dilator squeezes into the observation hole, so that the cervix is ​​not fully exposed, which is not conducive to observation And operation, the opening at the front end is too large, which makes the patient feel uncomfortable; it only has the function of dilation, and an additional light source is needed when inspecting the inside of the vagina, but the external light source is narrow, making the doctor's observation unclear and unable Observation is comprehensive. Although there is a vaginal dilator with a light source, it only has a white light source, and some secretions or diseased substances in the vagina cannot be clearly displayed under the white light.

In addition, medical staff need both hands to operate, and the whole process is relatively cumbersome
