摘要

A better understanding of the abdominal wall biomechanics could help designing new treatments for incisional hernia. In the current study, an experimental protocol was developed to evaluate the contributions of the abdominal wall components to the structural response of the anterior part of the abdominal wall. The specimens underwent 3 dissections (removal of (1) skin and subcutaneous fat, (2) anterior rectus sheath, (3) rectus abdominis muscles). After each dissection, they were subjected to air pressure up to 3. kPa. Ultrasound images and associated elastographic maps were collected at 0, 2 and 3. kPa in the intact state and strains on the internal surface were calculated using stereo-correlation in all states. Strains on the rectus abdominis and linea alba were analyzed. After the dissection of the anterior sheath of the rectus abdominis, longitudinal strain was found significantly different on the linea alba (5% at 3. kPa) and on the rectus abdominis area (11% at 3. kPa). The current results highlight the importance of the rectus sheath in the structural response of the anterior part of the abdominal wall ex vivo. Geometrical characteristics such as thicknesses and radii of curvature and mechanical properties (shear modulus of the rectus abdominis, e.g. at 0 pressure the average value is 14. kPa) were provided in order to facilitate future modeling efforts.

KPa。在0,2和3中收集超声图像和相关的弹性映射图在完整状态下，在所有状态下使用立体相关性地计算内表面的菌株的KPA。分析了直肠腹部和Linea Alba的菌株。在腹部腹部的前护套的解剖后，在Linea Alba（3.kPa）和直肠腹部区域（3.kPa为3％）上发现纵向菌株显着不同。目前的结果突出了脐带鞘在腹壁前部的结构响应中的重要性。提供了诸如曲率厚度和半径的几何特征和弯曲的机械性能（直肠腹部的剪切模量，例如，在0压力下平均值为14.kPa），以便于将来的建模努力促进。
