英文摘要：

The application of medical robot technique in computer-aided surgery was a hot research topic at present. The concept of medical robot was introduced, and the necessity of its application in computer-aided surgery was also empha- sized. The state of arts of medical robot technique was discussed systematically in computer-aided surgery, covering the four aspects： orthopedic surgery, neurological surgery, laparoscopic surgery and intervention surgery. Besides, some cor- responding medical robot systems were also introduced. Through the analysis on the medical robot technique, the laparo- scopic robot was considered as the most promising research direction. There were four urgent problems concerning the laparo- scopic robot. Based on the four problems, further research questions and possible directions in the future were proposed.
