Hysteroscopic insertion is a tool used to treat female infertility after obstruction or partial obstruction of the fallopian tubes caused by tubal disease in women, resulting in the inability of the sperm to pass through the tubes and unite with the egg. The operation should be performed within 3-7 days after menstruation. First, the hysteroscope should be used to enter the uterus from the cervix, then inflate the uterus with fluid, and after dilating the uterus, the morphology of the uterine cavity and the opening of the tubes bilaterally will be seen, and then the tubal blockage should be unblocked on the side of the tubes with a Cook’s guidewire, and after unblocking, the fluid should be passed with Melan, and then the patency of the tubes should be seen. During the treatment period, we should pay more attention to rest, pay attention to personal hygiene, avoid straining and catching cold, abstain from sexual intercourse for 1 month, and prepare for pregnancy after 3 months after the operation.
