Evolution of a surgical device can sometimes set a new trend in the history of surgery. It is well recognized that the development of the surgical microscope generated new fields in surgery, such as neurosurgery, temporal bone surgery, and phonosurgery. Also, the spread of the flexible and rigid endoscope in the 1990s produced functional endoscopic sinus surgery as well as laparoscopic surgery, video-assisted thoracoscopic surgery, and arthroscopic surgery, which enabled early diagnosis and minimally invasive surgery. In this paper, we review recent and novel surgical devices, such as navigation systems, narrow band imaging technique, three-dimensional endoscope systems, and especially, robotic surgical systems, and discuss the future of surgical devices.
