[0002] Congenital absence of vagina is a congenital malformation caused by the incomplete development of bilateral paramesonephric ducts or the dysplasia of the tail ends of bilateral paramesonephric ducts. Patients with congenital absence of vagina have normal development of secondary sexual characteristics such as breasts, body shape, and vulva, but no vaginal opening, and no uterus or only rudimentary uterus, and ovarian function is mostly normal. Currently, artificial vaginoplasty is used clinically to treat congenital absence of vagina. This operation uses amniotic membrane, peritoneum, skin, etc. to replace vaginal formation. After the operation, a mold needs to be placed to keep the vagina of sufficient length and width, and the vaginal mold needs to be worn continuously for a certain period of time to prevent vaginal contracture and stenosis. The existing vaginal mold is fixed in size and length, which is not suitable for different patients; at the same time, the vaginal mold needs to be regularly removed for disinfection and medication is placed in the vagina after long-term wearing, which is time-consuming, labor-intensive, and unhygienic; the vaginal mold is easy to slip and shift.

[0003] The Chinese utility model patent application number 201820219877.3 discloses a multifunctional adjustable vaginal mold, which changes the size of the vaginal mold by pumping air to suit different patients. However, the device changes the size of the mold by pumping air, which is cumbersome to operate, has a complex structure, and is relatively expensive. The mold has a large front end and a uniform thickness at the rear end, while the vaginal opening is smaller than the vagina. Molds of the same thickness will cause discomfort when placed in the human body and are easy to shift. Utility Model Content
