Abstract: An arthroscopical surgical method using an ultrasonic treatment device for a joint includes: transmitting ultrasonic vibration to a treatment portion of the ultrasonic treatment device, removing an injured region of an articular cartilage so that a subchondral bone is exposed, and forming a cartilage edge which is nearly angled at 90° with the exposed surface of the subchondral bone to form a pool-shaped depression; forming a hole which pierces up to a cancellous bone of the subchondral bone through the depression, and scratching blood vessels in the cancellous bone; causing bleeding from the blood vessels so that blood is retained in the depression via the hole.

Abstract: An endoscope system includes a convex-portion specifying section that detects a convex portion in a picked-up image of a subject picked up by an image pickup section, and a convex-portion-size calculating section that detects a convex portion in a predetermined size range on the basis of information concerning the convex portion. An illumination section includes a plurality of illumination-light emitting sections that illuminate the subject with lights in bands different from one another from directions different from one another. The plurality of illumination-light emitting sections are provided on a distal end side inner circumferential surface of a cylindrical cap attached to the distal end of an insertion section of an endoscope to specify an image pickup range of the image pickup section.
