Abstract: A vibration generating unit includes an element unit, and the element unit includes a piezoelectric element generating an ultrasonic vibration by being supplied with electric power. A proximal-side fixing member abuts on the element unit from a proximal direction side and a distal-side fixing member abuts on the element unit from a distal direction side such that the element unit is sandwiched between the proximal-side fixing member and the distal-side fixing member in a longitudinal direction. The distal-side fixing member has a greater acoustic impedance than the proximal-side fixing member.

Abstract: An optical-scanning-type observation probe is provided with: an imaging optical system that illumination light scanned by an optical scanner enters and that focuses the illumination light in the form of a spot, multiple times; a projection optical system that emits illumination light coming from a focus position focused by the imaging optical system, toward a subject in the form of a spot; and a light-receiver that is provided independently of the imaging optical system and the projection optical system and that receives reflected light of the illumination light, the reflected light coming from the subject, via a light path different from that of the imaging optical system and the projection optical system.

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.
