[0002] The uterine manipulator is used for total or subtotal hysterectomy, and mainly includes a central guide rod, a cervical fixator, and a vault cup. Its characteristics are that a cervical support is provided at the front of the cervical fixator, and its front end is a threaded cone; a central channel is axially opened in the cervical fixator, and the central guide rod passes through it; the vault cup is wrapped around the outer circumference of the cervical fixator, and its front inner diameter is greater than or equal to the diameter of the cervical support to form a cup body, and the rear part is narrowed to form a handle, and a screw is provided at the end of the handle to fix the vault cup at a specific position of the cervical fixator.

[0003] However, the existing uterine manipulator mainly relies on the dome cup to penetrate into the patient's uterine cavity. The dome cup fits with the patient's uterine cavity muscles to fix it. However, the dome cup is generally made of silicone material with a soft texture and structure, and the tissue in the patient's uterus is soft. If it only relies on the dome cup to support the uterine cavity, the automatic lifting effect of the patient is prone to displacement, and the lifting effect is not good. Therefore, we proposed a new adjustable uterine manipulator. Utility Model Content
