diameter, and semi-elliptical shallow openings are provided on the front and rear sides of the upper part to fix the duckbill. By pressing the
airbag, the anti-off support, the expansion part and the limit
locking mechanism can be attached to the cervical wall of the
uterus under the action of air pressure, and the inner
diameter of the expansion part can be adjusted according to the treatment cycle, so that the diameter of the expansion part can be adjusted at any time , to meet the treatment requirements, at the same time, under the state of internal air pressure, the ejector rod makes the connecting rod stretch out, so that the expanded part is stretched out and contacts the inner wall of the
cervix, which can prevent it from falling off; the internal filling of the limit
locking mechanism After the gas is released, the limit
locking mechanism is opened to contact the bottom of the
