DYNAMIC DESIGN OF THE ACTIVE PROSTHETIC ARM APPROACHED BY THE SIMULATION SURGERY METHOD

为了为每个病例制作高功能的主动假体做好准备，应根据患者的运动、行为和工作方式进行相应的设计。为此，最近正在建立一个模拟手术的概念。本研究旨在利用目前在国外推广的动态设计系统方法，作为模拟手术，对主动前凸臂进行动态设计。为此，在第一年(1994)，主要建立了动态设计系统。即对整个系统进行规划，为三维实时仿真准备计算机硬件和软件，以及整个系统的设计。去年(1995年)，我们的研究计划是由长谷川开发以三维实时动态仿真为主的软件，由宫家进行整个系统的规划和仿真评估，此外，医学评估和总结本研究也是由宫家进行的。因此，1)通过1994.2)购买的图形工作站计算机进行模拟的准备和执行。对模拟进行评估，并进行对象设计。3)进行了医学评价。与这些结果相比，由于大量的活体肌肉运动，分析结果，还需要更多的讨论，以完成一个临床有用的系统。

In order to prepare for each cases to make high functional active prostheses, respective design considering of patient's movements, behaviors, and working forms should be performed. For this purpose, a concept of the simulation surgery is recently being established. This study was aimed to design dynamically the active proshtetic arm using the dynamic design system method, which is now spreading in other world, as the simulation surgery. In addition to this, the cheaper work station computer was aimed to use this method.For these purposes, in the first year (1994) , the dynamic design system was mainly established. That is, planning of the whole system, preparing the computer hardware and software for the three-dimensional realtime simulation, and designing of the whole system were performed.In the last year (1995) , our study was planned that the software for the three-dimensional realtime dynamic simulation, which takes main role of the system, was developed by Hasegawa, and that planning of the whole system and evaluating the simulation was performed by Miyake, addition to these, medical evaluation and summarizing this study was also performed by Miyake. Consequently, 1) preparing and performing the simulation was done by the graphic work station computer, which was purchased in 1994.2) Evaluation of the simulation and a object design was performed. 3) Medical evaluation was performed.Contrary to these results, because of plenty many of living muscle movements, analytical results, a little discussions need more to accomplish a clinical useful system.
