In this paper, the application of new visualization technologies in correction of funnel chest is presented. Often, such defects cause problems with breathing, and therefore, to improve the cardiorespiratory efficiency, a correction is required. The virtual model of chest was formulated to determine the strains and stresses after correction of deformation with using the stabilizing plate. From biomechanical point of view, the knowledge of the load-affecting stabilizer is necessary to select optimal parameters of the plate. The force-affecting plate that was used in the correction of chest deformation by Nuss method was determined on the basis of finite element model of funnel chest. The main aim of this work was to select the optimal thickness of plate. Calculations were conducted for three alternative constraints.
本文介绍了新的可视化技术在漏斗胸矫正中的应用。这种缺陷常常导致呼吸问题，因此需要进行矫正以提高心肺效率。通过使用稳定板来确定变形后的应变和应力，制定了胸部的虚拟模型。从生物力学的角度来看，需要了解受力稳定器的知识，以便选择最佳的板参数。基于漏斗胸的有限元模型，确定了 Nuss 法矫正胸壁变形所使用的受力板。这项工作的主要目的是选择最佳的板厚度。针对三种不同的约束条件进行了计算。
