Our main work consists in modeling of the female pelvis and uterus, as well as the human fetus. The goal of this work is to recover the different forces generated during the delivery. These forces will be input to the haptic obstetric training tool BirthSim which has already been developed by the Ampère Laboratory at the INSA of Lyon. This modeling process will permit us to develop a new training device to take into account different anatomies and different types of delivery. In this paper, we will firstly show the different existing haptic and virtual simulators in the obstetric world with their advantages and drawbacks. After, we will present our approach based on a biomechanical modeling of concerned organs. To obtain interactive time performance, we proceed by the simplification of the organs anatomy. Then, we present some results showing that FEM analysis can be used to model forces during childbirth. In the future, we plan to use this work to more accurately control a childbirth simulator.
我们的主要工作包括对女性骨盆、子宫以及人类胎儿进行建模。这项工作的目标是恢复分娩过程中产生的不同力量。这些力量将被输入到触觉产科训练工具BirthSim中，该工具已由里昂国立应用科学学院的安培实验室开发。这个建模过程将使我们能够开发一种新的训练设备，以考虑不同的解剖结构和不同类型的分娩。在本文中，我们将首先展示产科领域现有的不同触觉和虚拟模拟器及其优缺点。之后，我们将介绍基于相关器官生物力学建模的方法。为了获得交互式时间性能，我们通过简化器官解剖结构来进行。然后，我们展示了一些结果，表明有限元分析可用于模拟分娩过程中的力量。未来，我们计划利用这项工作更精确地控制分娩模拟器。
