In recent years, hysteroscopy has been widely used in clinical practice. Under the direct view of hysteroscopy, changes in the morphology of the endometrium can be observed and the degree, scope and nature of adhesions can be understood, and the operation under direct view of hysteroscopy can completely and accurately separate the adhesions, restore the normal morphology of the uterine cavity, promote the repair of the endometrium, increase the menstrual flow, and improve the conception rate. It is an effective treatment for uterine adhesions. Currently, there are many methods to prevent re-adhesion of the uterine cavity, with the IUD + IUD cycle being the most common. It has been clinically found that the use of Chinese herbal medicine after hysteroscopic separation of cavity adhesions is effective in treating post-abortion amenorrhea and scanty menstruation. Postoperative IUD can act as a barrier to prevent the anterior and posterior walls of the uterus from adhering to each other, while stimulating the uterus to secrete prostacyclin to increase menstrual flow. Together with Chinese herbal medicine, it improves blood circulation and supply to the uterus and ovarian tissues by activating blood circulation and removing blood stasis, and promotes endometrial growth. At present, there are more clinical treatment methods for amenorrhea and low menstrual flow after abortion, all of which have achieved certain efficacy, but their course of treatment is often longer. Therefore, women of childbearing age should actively use contraceptive measures and avoid or reduce abortion as much as possible, while medical personnel should strictly implement the operating procedures during abortion, prohibit rough operation and excessive suction and scraping of the uterine cavity to prevent complications.
