外科手术机器人技术发展现状及关键技术分析

外科诊疗是医疗机器人研究和应用最广泛也是比较成熟的领域，目前研究主要集中在脑神经外科、整形外科、介入式无损检测、角膜移植等领域．为促进我国医疗机器人技术的研究和发展，在充分论述医疗机器人研究意义的基础上，对国内外典型外科手术机器人的研究及应用状况作了详细介绍，并对研究医疗机器人所涉及的手术机器人机构、医学三维图像建模、虚拟手术仿真、遥操作网络传输等关键技术进行了详尽的分析，同时指出了今后的发展方向．

Present status and key techniques of surgical robotics

Medical robotics has been playing an increasingly important role in the surgical areas world wide. A series of surgical robots havs already been developed overseas. In China, researchers also paid much attention to researches on brain neurosurgery, orthopaedics, scatheless inspection, cornea transplantation and etc. The development and application of medical robots, at home and abroad and such key techniques as surgical robot prototype design, 3D medical imaging modeling, virtual surgery simulation, teleoperation and communications via networks, are reviewed in details. The trend of future development is forecast as well.
