[0002] After searching the existing Chinese patent document with the announcement number CN218684638U, an adjustable post-vulvovaginoplasty vaginal dilation device is disclosed, including an airbag and an inflatable member, the inflatable member is installed inside the airbag, the airbag is provided with a telescopic portion and an expansion portion isolated from each other, the telescopic portion is arranged at the upper end of the expansion portion, the inflatable member passes through the telescopic portion and the expansion portion, the telescopic portion and the inflatable portion are inflated by the inflatable member, and the device is provided with the telescopic portion and the expansion portion, so that the vaginal dilation device can be expanded laterally, so that the thickness of the vaginal dilation device is adjustable, and can also be telescoped longitudinally, so that the vaginal dilation device can be adjusted according to personal conditions, and the inflation adjustment can be more in line with the patient's personal conditions.

[0003] Vaginal stenosis is one of the long-term complications of pelvic radiotherapy for gynecological malignancies (cervical cancer, endometrial cancer or vaginal cancer, etc.), especially for patients receiving vaginal brachytherapy. After radiotherapy, patients experience vaginal stenosis, adhesion, deformation, reduced elasticity, etc. In severe cases, vaginal atresia may occur, leading to dyspareunia, decreased quality of sexual life, and serious impact on the relationship between husband and wife. In addition, vaginal stenosis can also lead to the inability to conduct adequate transvaginal examinations, which affects the diagnosis and further treatment after disease recurrence. At present, the commonly used clinical method to prevent vaginal adhesion or stenosis is to instruct patients to use vaginal douches at home. Commonly used gynecological douches are mainly composed of balloons and douche tubes. Because the diameter of the douche tube is too thin, it cannot play a role in dilating the vagina and cannot effectively prevent vaginal stenosis after radiotherapy. In addition, although duckbill dilators can be used to prevent vaginal stenosis to a certain extent in clinical practice, it is inconvenient for patients to use them by themselves, and improper operation may cause damage to the vaginal wall or cervix, causing pain or bleeding. In addition, the size is limited, only large, medium and small, and individual dilation cannot be performed according to the size of the patient's vagina. Utility Model Content
