Background

The cervix is one of important tissue organs in the female reproductive system, from an embryo and a female fetus to an old woman, relates to the disease prevention and treatment and health care problems of gynecology, obstetrics, family planning, women health care, reproductive health and the like in the female lifetime, relates to the health, family happiness, economy and social problems of the female, and is closely related to sex, reproduction and the like. The cervix can have various diseases, including embryonic dysplasia, inflammation, neoplastic lesions, benign tumors, malignant tumors, injuries, cervical infertility, family planning, assisted reproduction technology, cervical sex, cervical pregnancy, cervical dystocia and other obstetric and gynecologic problems. While cervical cancer is the most common gynecological malignancy. Early cervical cancer often has no obvious symptoms and signs, and the cervix may be smooth or indistinguishable from cervical columnar epithelial ectopy. The appearance of the cervix is normal, so that the patients with cervical canal are easy to miss or misdiagnose. For patients with cervical cancer primary screening (TCT combined HPV detection) abnormality, a referral colposcopy is needed, cervical canal scratching is needed if necessary, a curette is mainly used for probing into the cervical canal to scratch, and tissues are scraped for pathological examination.
