Background
Hysterosalpingography is currently the primary examination for diagnosing infertility in married women, by which fallopian tube lesions that lead to infertility can be detected. Currently, there are two main types of hysterosalpingography catheters used clinically:
1. balloon catheter: during the radiography, a catheter is inserted into the uterus, a filling saccule is used for blocking the internal opening of the cervix, and then contrast agent is injected through the catheter to fill the uterus and the fallopian tube. The drawbacks of such balloon catheters are: patients have obvious pain during operation and are easy to bleed; the balloon is easy to cover the lesion, so that missed diagnosis is caused; the technical difficulty of intubation is high.
2. A conical head conduit: the tapered catheter is made of materials such as metal or silica gel, and the tapered head of the catheter is used for plugging the external cervical orifice in the angiography to perform the hysterosalpingography. The disadvantages of this tapered head catheter are: the blockage is incomplete, and the contrast agent is easy to leak to the vagina; when a deflected uterus and cervix are encountered, the catheter head is hard and short and thick and is easy to abut against the wall of the cervix, so that the contrast fails. In addition, the conical head is positioned at the rear part of the catheter head, so that the visual line is easily obstructed in the intubation process, and the intubation difficulty is caused.
