Abstract    Re-understanding the mechanical properties of the abdominal wall from the perspective of biomechanics, reinterpreting how to reconstruct the abdominal wall may help to choose a reasonable surgical method to better reconstruct the structure and function of the abdominal wall and avoid complications. From the anatomical point of view, the core of abdominal wall reconstruction is to repair the defective tissue, and from the biomechanical point of view, the purpose of repairing the defect is to restore the integrity and function of the abdominal wall's mechanical structure. In clinical work, it is necessary not only to restore the abdominal wall muscle and tendon structure coverage, but also to restore the integrity of the abdominal wall mechanical structure, and to apply patches to increase the strength of the repaired area. In the face of huge defects, the priority principle should be followed and the important structure of the central area should be rebuilt first. In addition, when applying CST technology, the indications must be strictly controlled, and the separation range should not be too large. It is necessary to protect the white line, posterior rectus abdominis sheath, umbilicus, transverse abdominis and meniscus and other stress structures. Finally, the mechanical structure damaged during the operation should be repaired and strengthened with a patch.
