Abstract: Provided is a scanning endoscope including: an insertion portion that has a distal-end section and a proximal-end section; a light-guide optical system that guides illumination light toward the distal-end section; a spherical lens that is disposed in the distal-end section and that radiates the illumination light guided by the light-guide optical system onto a subject; an optical waveguide that extends from the distal-end section to the proximal-end section, that receives observation light coming from the subject, and that guides the observation light; and a light detector that detects the observation light guided by the optical waveguide, wherein the optical waveguide is inclined, at the distal-end section, in such a direction as to approach an optical axis of the spherical lens toward a distal end.

Abstract: A medical device system that includes an ultrasound transducer and a processor. The ultrasound transducer includes a plurality of electrode plates to which a drive signal is supplied, and a plurality of piezoelectric elements that are alternately arranged with the electrode plates, and that generate ultrasound vibrations according to the drive signal. The ultrasound transducer also includes an electric wiring that electrically connects the electrode plates adjacent to each other, and a memory that stores reference information regarding specific initial characteristics. The processor analyzes the generated ultrasonic vibrations to determine a resonance point of the ultrasound transducer, and detects resonance point information regarding the resonance point. The processor then determines whether an abnormality has occurred in the ultrasound transducer by comparing the stored reference information and the detected resonance point information.

Abstract: A vibrating body unit includes a vibration generator, a vibration transmitter and first amplitude enlarger. The vibration generator generates ultrasonic vibration whose amplitude has a predetermined correlation with a frequency. The vibration transmitter has a proximal end and a distal end while the vibration generator is attached from a proximal side, and transmits the ultrasonic vibration to a distal side in a longitudinal axis direction. At least one first amplitude enlarger is provided in the vibration transmitter, and enlarges the amplitude of the ultrasonic vibration at a first amplitude enlargement rate in a direction of transmission of the ultrasonic vibration, the first amplitude enlargement rate having a correlation with the frequency opposite to the predetermined correlation.
