Objective： To research the competitive situation of technical research on the field of surgical robot and analyze direction of technical development of this field. Methods： The data of Derment Innovation（DI） platform were applied, and the patent analysis method was adopted to combined with visual tool to analyze patents of surgical robot field from various aspects such as the number of patent application, technology life cycle, the trend of regional development, competitor and trend of technical development. Results： There were 1491 patent applications in the globally surgical robot field, and technological fields were concentrated in endoscope, surgically mechanical arm, electronic data processing system, intervention, implantation of related equipment, regulatory system, image processing and transmission, stress and torque, etc. United States and China not only were the major technical birthplace but also were the important target markets in surgical robot field. And enterprises were the main research and development institutions in abroad, while colleges and universities were main institutions in China. Conclusion： The field of surgical robotics is in a fast developing period, and endoscope and surgically mechanical arm are the focusing technical development direction and they obtain most attentions.
