The present invention provides a medical system that is suitable for both local treatments and large surgical motions and reduces operating time. This medical system (1) is provided with: a first robot arm (3) comprising a first manipulator (12) having a first treatment section (15) and a first imaging unit (14) having a field of view including the movable range of the first treatment section (15) a second imaging unit (10) having a wider field of view than the former field of view a display unit (20) for displaying a video from the first or second imaging unit (10, 14) a switching unit (22) for switching the video an operation unit (6) for inputting an operation command for the first manipulator (12) and the first robot arm (3) and a control unit (7) for controlling the first manipulator (12) and the first robot arm (3) on the basis of the operation command. When the video is switched to that from the second imaging unit (10), the control unit (7) controls the first robot arm (3) and the first manipulator (12) on the basis of the operation command. When the video is switched to that from the first imaging unit (14), the control unit (7) controls the first manipulator (12) on the basis of the operation command.La présente invention concerne un système médical qui est adapté à la fois à des traitements locaux et à de grands mouvements chirurgicaux et qui réduit la durée dopération.
