[0002] The cervix, also known as the uterine cervix, is one of the important tissue organs in the female reproductive system. From the embryo and female fetus to old age, the cervix involves the prevention and treatment of diseases and health care issues such as gynecology, obstetrics, family planning, women's health and reproductive health throughout a woman's life. It involves the health of women themselves, family happiness, economic and social issues, and is also closely related to sex and reproduction.

[0003] In the prior art, when performing a hysterectomy, the vagina needs to be stretched and then the hysterectomy is performed. The cervical cup with a stretching structure used has a fixed structure size and cannot be adjusted, and the adjustment method of some adjustable parts is relatively complicated, and the structure is not simple and convenient enough. In addition, it does not provide good protection for patients. Some design structures will also affect the vision of medical staff during surgery. In addition, the cervical cup in the prior art does not have an auxiliary fixing structure that is convenient for assisting subsequent surgical operations, which requires medical staff to hold it continuously. After a long time, the medical staff will also become tired and the hand tremors will affect the surgical process. Although an external bracket structure is designed in the prior art, it is placed on the outside. First, the operation is not convenient enough. Second, it affects the operation of medical staff. For this reason, a cervical cup for abdominal hysterectomy is designed to solve the above problems. Summary of the Invention
