[0002] In the field of obstetrics and gynecology, female infertility problems are concerned, and fallopian tube lesions account for a considerable proportion, especially the most common fallopian tube obstruction. The traditional examination and treatment means for fallopian tube has obvious limitations. Fallopian tube fluid infusion can only roughly determine whether it is unobstructed or not, and cannot understand the internal specific lesion details; fallopian tube radiography can observe the shape and patency, but some patients may be allergic to contrast medium, and the diagnostic accuracy will be greatly discounted when encountering fallopian tube adhesion and other conditions. Under this condition, the guide wire guide tube technology emerges as the times require as a more accurate method for diagnosing and treating fallopian tube lesions. It introduces the guide wire into the fallopian tube with the help of the catheter, which can not only directly observe the internal condition, but also can perform dredging operation when blockage is found. When the proximal end of the fallopian tube is blocked, the guide wire can accurately reach the lesion under the accurate guidance and support of the guide tube to try to dredge. However, the existing fallopian tube guide wire guide tube disclosed in the Chinese utility model patent with patent No. CN 104161575 A, although it solves some problems faced by traditional examination and treatment means to a certain extent, still has many shortcomings.
