[0002] The uterine cavity is the space of the uterus, which is located in the center of the pelvic cavity. The normal uterus is in an anteriorly tilted and flexed position in the pelvic cavity. Before performing surgery on the patient's uterine cavity, it is necessary to use an expansion device to expand the patient's uterine cavity to facilitate surgery in the uterine cavity. Generally, the expander is inserted into the patient's uterine cavity to expand the uterine cavity. The existing expansion device is regulated by human pressure, and it is not easy to control the force. Excessive force may cause the risk of uterine cavity tearing, and less force will make the uterine cavity unable to expand to the appropriate size. At the same time, during a long operation, medical staff need to stand for a long time holding the expansion tool and maintain a certain posture, which not only consumes physical strength, but also the shaking of the hands and the expansion tool affects the progress of the operation.
