Even though the incisional hernia repair surgery is a well known procedure, mechanical properties of the tissue-implant system are unknown so the implantation of the repairing mesh is quite intuitive and, recurrences of the illness still take place. The main objective of the study is to define an operated hernia model that can be used for surgery planning and the assessment of the repair persistence. The load applied to the structure corresponds with this widely accepted as the one that can cause the hernia recurrence. In the proposed solution, the reaction forces calculated when the extreme abdominal pressure acts on the model, are considered as the crucial factors in the repair planning and evaluation of the connection strength. These reactions representing the tissue-implant junction forces can not exceed the limit value experimentally obtained for the connection of the synthetic mesh and porcine tissue described in literature. The achieved results of the finite element simulations are compared with experiments and the proposed solution reveals good accuracy.
