Fine reconstruction modeling and mechanical analysis method for female pelvic floor system under sagittal plane

Abstract

The invention discloses a refined reconstruction modeling and mechanical analysis method for a female pelvic floor system under a sagittal plane, and belongs to the field of analysis and exploration of female pelvic floor stress sexual dysfunction. The method comprises the following steps: firstly, taking organs and ligaments of a female pelvic floor system as research objects, obtaining a two-dimensional image picture of the pelvic floor organ based on a nuclear magnetic resonance technology, and accurately reconstructing a contour curve and a geometric model of the female pelvic floor organ under a sagittal plane by using computer-aided design software and a curve fitting method; secondly, a mechanical calculation formula of ligaments such as a main ligament and a sacrum ligament under the sagittal plane is given, and a finite element analysis method of female pelvic floor system biomechanics under the sagittal plane is provided. The method is suitable for geometric model reconstruction and biomechanical analysis under the sagittal plane of female pelvic floor systems of different ages and types, can be used for developing a mechanical analysis system and an intelligent auxiliary analysis system, and has important guiding significance for exploring and researching the mechanical action law and damage mechanism of the female pelvic floor systems.

Description

technical field [0001] The invention relates to the field of analysis and exploration of female pelvic floor stress dysfunction, mainly to study the mechanical action law and damage mechanism of the female pelvic floor system, specifically a refined reconstruction model of the female pelvic floor system under the sagittal plane and mechanical analysis methods. Background technique [0002] The incidence of female pelvic floor uterine prolapse combined with prolapse of the anterior or posterior vaginal wall is high. It is a common disease in multiparas of all ages. The prevalence of POP is as high as 37%, which seriously affects the physical and mental health and quality of life of middle-aged and elderly women. . [0003] Pelvic floor stress dysfunction (urinary incontinence, pelvic organ prolapse, etc.) (pelvic floor stressdysfunction, PFSD) has the characteristics of high incidence, poor curative effect, and many controversial issues. There is a lack of understanding of ...

Problems solved by technology

Most of these pelvic floor models are rough representations of some organs and tissues of the pelvic floor system, with incomplete structures and low precision. They lack detailed descriptions of the morphological and positional characteristics and biomechanical cha
