This invention relates to a uterine manipulator and an automatic uterine manipulator system, comprising a fixed uterine manipulator, a movable uterine manipulator, and a control mechanism. The control mechanism drives the movable uterine manipulator to coaxially engage with the fixed uterine manipulator, and pushes both the fixed and movable uterine manipulators into the vagina, reaching the cervix. The fixed uterine manipulator then seals and engages within the vagina, securing the cervix. The control mechanism also drives the movable uterine manipulator axially away from the fixed uterine manipulator by a certain distance within the vagina. Finally, the control mechanism detaches the fixed uterine manipulator from the body, removing the excised tissue. This invention, by sealing and engaging the uterine manipulator internally at the junction of the vagina and cervix, and securing it to the cervix and upper vagina, avoids friction between the uterine manipulator and diseased tissue, allowing for normal uterine manipulation, preventing the detachment of diseased tissue during surgery, and facilitating the removal of excised tissue. This improves surgical efficiency and reduces the risk of infection and tumor cell detachment.
