The cervical conization is used for the surgical treatment of benign diseases of the cervix. Cervical conization is applicable to: cervical biopsy is carcinoma in situ, to determine lesion extent and presence or absence of infiltration; severe atypical hyperplasia of the cervix; the cervical scraping is positive for a plurality of times, but the biopsy can not find the lesion.

When the cervical conization is performed, the cervix cannot be well exposed, and the existing cervical conization method comprises the following steps: firstly, a speculum is used for propping open and fixing a vagina and inserting a catheter, then two mouse-tooth forceps are inserted into the speculum to clamp the two sides of a cervix, the cervix is pulled for a short distance and is completely exposed, then a special scalpel for cervical conization is used for inserting the cervix, the cervix is subjected to annular conization, the size and the depth of the conization depend on the experience and the feeling of a surgeon, and after the operation is finished, electrocautery hemostasis and cervical suture forming are carried out.

In the existing operation method, two mouse tooth forceps are used for stretching into the two sides of the cervix from the speculum, so that the space for operation is very small, and the operation is quite inconvenient; the depth and width of the cervix cannot be measured when the circular conization is performed, but for patients of different ages, the conization volumes required to be resected are different according to different pathological degrees, and the length of the remained cervix tube is also unknown after the conization, so that for patients with pregnancy requirements, the cervix can cause cervical insufficiency when the pregnancy is performed again after the operation, and the abortion can be caused. In addition, the cervix uteri cannot be well pulled to be in the horizontal direction by the existing method, so that the actually resected cervical vertebra of the conization part is uneven, and the front lip is more than the rear lip. Moreover, since the specific length of the cervical canal is unknown, the resection depth may not be sufficient for the purpose of clear diagnosis, which may lead to the possibility of secondary operation.
