Abstract：The competitive situation of surgical robots were discussed by patent analysis and visualization. Results showed that there
were 2935 patent applications. Technical fields were mainly concentrated in electrical stimulation therapy and implantable neurostimulator.
United States and China were both the major technical birthplace and the important target markets in neuro-stimulator
field. This paper could provide a new angle for research and development of neuro-stimulator field from the angle of informatics.
