随着计算机技术的不断进步，“云”计算这种以数据为核心的信息系统理念以其更为科学的架构特点和运作规则被应用到了医院数据系统中。本文旨在通过对医院常用“云”数据系统的各种类型进行分析，研究“云”数据系统在数据使用效率、系统稳定性进行分析。在此基础上以其在数字化手术室的应用，特别是在虚拟现实（VR）远程教学上的应用为例，进行说明和展望。希望藉此能够给予广大从业者一定的参考与帮助。

With advances in computer technology, "cloud" computing this data-centric information systems more scientific concept of its architectural features and the operating rules are applied to hospital data systems. This article aims to analyze the hospital through various types of common "cloud" data systems to study the "cloud" of data in the data system efficiency, system stability analysis. On the basis of its application in the digital operating room, particularly in the application of virtual reality (VR) distance learning, for example, will be described and discussed. We are hoping to be able to give the majority of practitioners some reference and help.
