目前，在构建手术模拟器时，由于需要实时生成高度逼真的手术图像，通常使用高性能图形工作站（GWS）。但在成本、操作、工作环境等方面存在问题，阻碍了该模拟器的广泛应用。为了解决这一问题，作者基于GWS上开发的手术模拟器的评估结果，构建了一个用于眼科医生玻璃体视网膜手术培训的实时pc外科模拟器。通过本研究，确定了仿真器的必要条件，并成功构建了满足这些条件的基于pc的手术仿真器。构建的系统可以执行以下操作。手术图像通过双目立体视觉显示器以立体视觉显示。通过使用模拟工具装置提供手术工具插入的触感。手术现场可以通过操作脚踏开关来控制。所构建的手术模拟器提供了一个有效模拟真实手术的环境。如果越来越多的眼科医生可以更容易地使用所提出的模拟器进行重复手术训练，外科技术将得到改进，新的外科手术方法可能会发展。©2002 Wiley期刊公司系统比较，33(7):11 - 20,2002；在线发表于Wiley InterScience （www.interscience.wiley.com）。DOI 10.1002 / scj.10076
Presently, in constructing a surgical simulator, a high-performance graphics workstation (GWS) has generally been used because it is necessary that a highly faithful surgical image be generated in real time. There exist problems, however, in cost, operation, and working environment, which have prevented the widespread use of the simulator. In order to solve this problem, the authors constructed a real-time PC-based surgical simulator for the training of ophthalmologists in vitreoretinal surgery, based on the results of evaluation of a surgical simulator developed on GWS. From this study, the necessary conditions for the simulator have been identified, and a PC-based surgical simulator satisfying these conditions has been successfully constructed. The constructed system can perform the following operations. The surgical image is displayed in stereo vision, through a binocular stereo vision display. The tactile sensation of surgical tool insertion is provided by using a simulated tool device. The surgery scene can be controlled by operating a foot switch. The constructed surgical simulator provides an environment which effectively simulates real surgery. If an increased number of ophthalmologists can use the proposed simulator more easily for repetitive surgery training, surgical techniques will be improved, and new surgical procedures may be developed. © 2002 Wiley Periodicals, Inc.
