However, the problem that the cervical orifice is not completely blocked by the cone still exists, and the contrast agent is easy to reflux and leak.

The vagina ultrasonic probe is needed to operate during oviduct ultrasonic radiography, the cone of the existing cone type radiography conduit easily blocks the view field of the vagina probe, and the vagina probe is difficult to cross the cone due to the thicker material of the cone part, so that the operation difficulty is caused by the limited operation view field. In addition, the vaginal probe is easy to collide with the hard catheter body in the operation process, so that the vaginal probe is damaged.
