Pelvic Organ Prolapse (POP) is a degenerative disease which causes pelvic organ to descend and shift due to weak pelvic floor supporting tissues caused by various reasons, further causes organ position and function abnormity, has main symptoms of prolapse of external pudendum blocks, and adopts non-operative treatment and operative treatment, wherein the operative treatment is a main treatment means for severe prolapse. According to the data in the United states, the rate of pelvic floor reconstruction surgery and anti-urinary incontinence surgery in women over 80 years old is 11%, 29% of the procedures requiring 2 repetitions and 14% of the procedures requiring 3 repetitions. Therefore, the pelvic floor reconstruction operation has great application prospect. In pelvic floor reconstruction surgery, namely pelvic floor base tissue reconstruction surgery, a doctor needs to fix a mesh and other repair materials or other mechanical supports into a pelvis to fix or provide a supporting effect for pelvic organ, so that pelvic floor supporting tissues are supplemented, and the pelvic organ can be stably fixed in a pelvic cavity and normally works; in the case of fixing the bladder by using the mesh, a doctor needs to insert a puncture tool into the pelvis through the vagina or the obturator foramen on the pelvis, feed the mesh into a position between the bladder and the pelvis by using the puncture tool, and then fix the mesh to a corresponding position on the pelvis by using an operation line, thereby achieving the purpose of supporting the bladder.

However, the existing pelvic floor reconstruction surgery is directly performed on a human body by adopting a blind-wearing mode, and because the existing human body models are used for displaying the pelvis and bones and muscles inside the pelvis, medical workers can only see the model to learn theoretical knowledge, cannot obtain actual operation training, and cannot exercise the puncture hand feeling, the condition that the puncture part is inaccurate easily occurs during the pelvic floor reconstruction surgery, firstly, the surgical effect is poor, and the condition that the operation needs to be performed again to adjust is caused; secondly, other injuries are easily caused to the patient, for example, pelvic organs such as bladder, rectum and uterus, or other human body structures such as blood vessels, sacral spinal ligaments and nerves inside the sacral spinal ligaments are punctured, and the health of the patient is greatly influenced. There is a need for a simulated trainer that provides pelvic floor reconstruction surgery to medical personnel.
