The traditional palace lifting device includes a fixed circular platform-shaped lifting part with a central opening, and the center of the fixed circular platform-shaped lifting part is fixed on the connecting rod. The shape and size of the lifting part are fixed and cannot be adjusted; because each person The body structure of women is different. Generally, the cervix of women who have not given birth is very small, while the cervix of women who have given birth is relatively large. However, the volume of the uterus of women is usually only about 5ml, so the shape of the uterus cannot be made The fixed conical shape with a large slope is stuck at the cervix by relying on the outer diameter of the circular frustum that gradually changes in diameter

When used by patients with a small cervix, the traditional uterine lifter cannot be used, and forced insertion into the cervix will cause injury to the patient. When used by patients with a large cervix, the traditional uterine lifter cannot be used, and the cervix cannot be relied on. The uterine lifter is fixed, so the uterine lifter with a fixed shape and size is difficult to ensure that the uterine lifter is suitable for all patients; moreover, when the traditional uterine lifter is withdrawn from the cervix after use, it will also bring pain to the patient. hurt, cause pain
