AIM: To establish the three-dimensional model of feminine pelvic floor,the complex geometric configuration of levator ani,pelvic and obturator internus,and to provide an initial preparatory work for further research on the mechanical mechanism of the feminine pelvic floor and the pathogenesis of the pelvic floor dysfunction from the perspective of the mechanics.

RESULTS: An independent three-dimensional geometric structure was obtained respectively for the obturator internus,levator ani,bladder,urethra,vagina and rectum,which exactly manifested the relative position of their anatomical structure.

Methods:18 adult rabbits were divided into three groups,and the sciatic nerve,femoral nerve and obturator nerve of the animals were severed.

That’s to say, the CP has a direct bearing on the pathological axis (lumbar vertebra-obturator nerve-adductor muscle of vastus medialis).

In surgical procedures, however, the stimulation to obturator nerve caused by the electrical current will lead violent adductor contraction, which can induce severe complications, such as bladder perforation.
