This paper presents mathematical modelling of an implanted surgical mesh used in the repair process of the abdominal hernia. The synthetic implant is simulated by a membrane structure. The author provides a material modelling of the implant based on the dense net model appropriate for technical fabrics. The accuracy of the proposed solution is evaluated by comparing the simulations of the dynamic behaviour of the system with the experiments carried out on physical models of implanted mesh. The model can be used to estimate the repair persistence for different mesh materials, fixing systems and different numbers of tacks to be provided during the surgery in order to resist the cough pressure and required action to avoid hernia recurrence. The persistence of the repaired hernia is assessed on the basis of the values of the forces in the tissue-implant joints because the usual form of the repair failure is due to as the joint disconnection or tissue failure.
本文介绍了用于腹疝修复过程的植入式外科补片的数学建模。合成植入物由膜结构模拟。作者基于适用于工业织物的密集网模型对植入物进行了材料建模。通过将系统动态行为的模拟结果与在植入补片物理模型上进行的实验结果进行比较，评估了所提解决方案的准确性。该模型可用于估计不同补片材料、固定系统以及手术中为抵抗咳嗽压力和避免疝复发所需采取的不同钉合数量情况下的修复持久性。修复疝的持久性是根据组织 - 植入物连接处的力值来评估的，因为修复失败的常见形式是连接处断开或组织失效。
