Medical system and medical system operating method

An operating method of a medical system that includes an endoscope that has an imaging section including a lens and is configured to be driven and operated by electric power, a controller configured to operate the endoscope and generate a display image from an image captured by the imaging section, a display configured to display the display image, and an input device configured to receive an instruction for the controller, the method comprising:

• recording a model of an organ of concern generated during preoperative planning, the model being arranged with respect to a first coordinate system,
• recording names of a plurality of sites in the organ of concern, and corresponding regions or points in the model that are defined by three-dimensional coordinates of the first coordinate system, the names being recorded in association with the corresponding regions or points;
• inputting, via the input device, a name of a site of interest among the plurality of sites in the organ of concern, and an operation task to be performed with respect to the site of interest;
• associating the first coordinate system of the model with a second coordinate system of a display space displayed by the display image;
• calculating, from a position of the site of interest in the first coordinate system, a position of the site of interest in the second coordinate system;
• and
• operating the endoscope with respect to the site of interest based on the operation task.
