A manipulator system includes arithmetic logic units for calculating an operation quantity per unit time of a power source mounted on a surgical instrument as a first operation quantity and calculating an operation quantity per unit time of the power source as a second operation quantity. A determining unit is used for outputting a shutoff signal for de-energizing the power source if the first operation quantity is smaller than a first threshold value and the second operation quantity is larger than a second threshold value. A cutoff unit is configured to cut off the drive signal output from the output unit to the power source in response to the shutoff signal output for de-energizing the power source from the determining unit.

Medical system

A multispectral image capturing apparatus has different spectral sensitivity characteristics of at least four bands. Three primary bands of the at least four bands have spectral sensitivity characteristics of standard RGB. At least one auxiliary band of the rest of the at least four bands excluding the three primary bands has a spectral sensitivity characteristic of a narrower bandwidth than bandwidths of the RGB.

A mixing ratio database stores information regarding a mixing ratio of plural materials for producing a color corresponding different color chart IDs. A plurality of pieces of color chart spectral information under determination illumination light are calculated using a plurality of pieces of spectral information of spectral reflection factors contained in a color chart and spectral information of the determination illumination light which is information of illumination light used for color chart determination. One of the calculated plural pieces of color chart spectral information which most closely matches spectral information of a subject is determined. A color chart ID which identifies the determined piece of color chart spectral information is output, and information of a mixing amount of each of the plurality of materials for the output color chart ID is also output based on the information stored in the mixing ratio database.
