The purpose of the present invention is to provide an ultrasound oscillator unit which may be made compact and which is provided with a circuit structure which has good operability with respect to wiring. This ultrasound oscillator unit comprises: an ultrasound oscillator array in which a plurality of ultrasound oscillators are arrayed in a semi-cylindrical shape; an electrode unit of the ultrasound oscillator array which is disposed on an end surface of the ultrasound oscillator array which is perpendicular to an array surface of the plurality of ultrasound oscillators; and a backing materiallayer which is positioned on the back surface of the inner side of the ultrasound oscillator array. The width of the backing material layer which is perpendicular to the array surface of the plurality of ultrasound oscillators tapers toward the side opposite to the array surface of the plurality of ultrasound oscillators. A cable wiring unit which is electrically connected to the electrode unit is disposed along the width of the backing material layer.
Description
technical field [0001] The present invention relates to an ultrasonic vibrator unit having an ultrasonic vibrator wiring structure for realizing a small ultrasonic device. Background technique [0002] With the main purpose of observing the gallbladder or pancreas through the alimentary canal, the ultrasonic endoscope is provided with an ultrasonic observation section at the distal end of the endoscope. In order to safely insert the ultrasonic endoscope into the digestive canal, the distal end of the ultrasonic endoscope is provided with an optical sensor and an illumination mechanism in addition to the ultrasonic observation unit, as in conventional endoscopes without an ultrasonic observation unit. , air supply port, water supply port and suction port. Therefore, the outer diameter of the distal end portion of the ultrasonic endoscope becomes large, which is a factor that reduces the operability of the ultrasonic endoscope and increases the burden on the patient inserted ...
