Abstract: In an arthroendoscopical surgical method, a resection target area, and a freshening treatment area which becomes repair surfaces with bleeding, are identified, and a resection line and a freshening line are drawn on a tear site in a meniscus, which is emphasized by fluorescence with use of a fluorescent medicine under excitation light. Using an ultrasonic treatment tool and an arthroscope, the resection target area is resected by a probe which generates ultrasonic vibrations, based on the resection line and freshening line under visible-light illumination. Thus, an inclined resection surface is formed, and planar repair surfaces with bleeding are joined and repaird.

Abstract: An imaging device includes a processor. The processor, in a manual focus mode, sets a focus evaluation area to have a larger size than the focus evaluation area set in an auto focus mode, generates assist information assisting adjustment of the in-focus object plane position based on a focus evaluation value obtained from an image of the focus evaluation area, and outputting the assist information to a display section.

Abstract: An endoscope system is provided with: a processor; a light source; and an image pickup device. The processor performs control for causing reflected light images corresponding to a predetermined period before start of the fluorescence occurrence period during the fluorescence non-occurrence period, among the reflected light images, to be recorded to the first storage medium; and, furthermore, performs control for causing the reflected light images to be recorded to the first storage medium during an after-end-of-fluorescence-occurrence period corresponding to a predetermined period with an end of the fluorescence occurrence period as a start point, and performs control for causing the reflected light images not to be recorded to the first storage medium during the fluorescence non-occurrence period after an end of the after-end-of-fluorescence-occurrence period.
