The prolapse after the total hysterectomy comprises prolapse of the front and back walls of the vagina and prolapse of the fornix of the vagina, and the colposacral fixation under a laparoscope is one of the internationally recognized gold standard operation formulas at present. In a laparoscopic sacrum fixation operation of a vagina, a bladder vaginal gap and a rectovaginal gap under a laparoscope need to be separated, but the separation of the bladder and the vaginal gap is difficult due to adhesion of the bladder and the front wall of the vagina or adhesion of the rectum and the back wall of the vagina caused by the previous operation of a patient, especially, the separation under the laparoscope has no hand feeling, the bladder and/or the rectum are easily damaged in the separation process, and the damage rate is about 3-10%. Traditional laparoscopic colposacral fixation can only solve prolapse of the middle pelvic cavity, i.e., the fornix and the upper vaginal segment. The existing improved laparoscope colposacral fixation improves the position for placing a patch, better supports the lower vaginal segment, and is suitable for patients with anterior and posterior pelvic prolapse by using the laparoscope colposacral fixation. In order to solve the surgical problem of bladder and/or rectum injury during the separation process, a fornix cup needs to be designed.
