Robotic surgical system and display method

A control device to be used in a robotic surgical system that comprises an endoscope, a manipulator configured to support a surgical instrument, and a remote control apparatus including an operation handle configured to operate the surgical instrument and a display device, wherein

• the control device is configured to generate a graphical user interface and display, on the display device, the graphical user interface on an image captured by the endoscope in an overlapped manner.
• the graphical user interface includes:
• a first area that displays a first graphical display indicating a movable range of the manipulator and an operable range of the operation handle in the movable range of the manipulator;
• and
• a second area different from the first area, wherein the second area displays a second graphical display indicating a required operation of the operation handle to return the operation handle to an inside of the operable range of the operation handle and/or to return the manipulator to an inside of the movable range of the manipulator.

A display method performed by a control device in a robotic surgical system, wherein the robotic surgical system includes:

• an endoscope;
• a manipulator configured to support a surgical instrument;
• a remote control apparatus including an operation handle configured to operate the surgical instrument and a display device;
• and the control device, the method comprising:
• acquiring an image captured by the endoscope;
• and
• generating a graphical user interface and displaying, on the display device, the graphical user interface on the image captured by the endoscope in an overlapped manner, wherein
• the graphical user interface displays, in a first area, a first graphical display that indicates a movable range of the manipulator and an operable range of the operation handle in the movable range and displays, in a second area different from the first area, a second graphical display that indicates a required operation of the operation handle to return the operation handle to an inside of the operable range of the operation handle and/or to return the manipulator to an inside of the movable range of the manipulator.
