Background
With the progress of the microecological research of the female genital tract, the research finds that bacteria symbiotic with human bodies exist in the female genital tract from bottom to top, and the bacteria symbiotic with the human bodies exist in the vagina, the cervix, the uterine cavity, the oviduct and the pelvic cavity. The stability of female genital tract microecology is closely related to female genital tract diseases, and is a current research hotspot. The female cervical canal is used as a boundary point between the vagina and the uterine cavity, and has the characteristics which are obviously different from the characteristics of the latter two in both the anatomy and the epithelial cell composition, so that the micro-ecological environment of the cervical canal is obviously different from the vagina and the uterine cavity, and the female cervical canal can be used for researching and predicting female genital tract diseases. The study on the microecology of the cervical canal by obtaining a cervical canal sample firstly solves the problem of how to avoid the pollution from the vagina in the sampling process. However, how to prevent vaginal microorganisms from polluting the sample obtained from the cervical canal and make the sample truly reflect the microecology of the cervical canal is an unsolved problem.
