According to a report by Winter Green Research, the market size of surgical robots was 3.2 billion USD in 2014. The report indicates that the North American market is currently the largest market, and due to increased government investment in healthcare, the restructuring of medical systems, and heightened awareness of minimally invasive surgery, the market focus will gradually shift to the Asian market in the future.

With the release of next-generation equipment, systems, and instruments, surgical robots will expand from the current large-scale open surgery to covering tiny parts of the body. It is estimated that the global surgical robot market size will reach 20 billion USD by 2021. Surgical robots have made significant progress in recent years. With the continuous development of the robotics industry, the development of medical robots has gradually attracted more high attention globally. The United States has designated surgical treatment machines, prosthetic robots, rehabilitation robots, psychological rehabilitation assistant robots, personal care robots, and intelligent health monitoring systems as six major future research directions. Europe plans to establish a "Robotics for Health-care" network to promote the development and application of medical robots in Europe. As a branch of medical robots, surgical robots, although only introduced a short 10 years ago, have likewise made significant progress.

At present, research on the application of robots in the medical field mainly focuses on surgical robots, rehabilitation robots, nursing robots, and service robots.
