Embodiment Construction
[0056] The ultrasonic vibrator unit according to the present invention will be described in detail based on preferred embodiments shown in the drawings.
[0057] figure 1 It is a schematic configuration diagram showing an example of the configuration of an ultrasound examination system using an ultrasound endoscope using the ultrasound transducer unit of the present invention.
[0058] figure 1 The illustrated ultrasonic examination system 10 can perform gallbladder or pancreas, which are difficult to examine in ultrasonic examination from the body surface of a subject such as a patient, via the body cavity of the subject, that is, the digestive tract such as the esophagus, stomach, duodenum, small intestine, and large intestine. Observation of dirty organs, and equipped with the ultrasonic vibrator unit of the present invention, will have an ultrasonic observation unit for acquiring ultrasonic tomographic images (hereinafter referred to as ultrasonic images), and an ultrason...

Provided is an ultrasonic vibrator unit that makes it possible to achieve a reduction in size, that has a high heat dissipation effect, that is suitable for use in an ultrasonic endoscope, and that has a wiring structure offering good workability when wiring the individual electrodes of an ultrasonic vibrator array and a large number of cables, a low degree of difficulty during work processes, anda low risk of disconnection as a result of the likelihood of a load being applied to the cables being low. The ultrasonic vibrator unit comprises: an ultrasonic vibrator array in which a plurality ofultrasonic vibrators are arranged; an electrode section comprising a plurality of electrodes that are electrically connected with each of the plurality of ultrasonic vibrators; an arc-shaped backingmaterial layer arranged on the rear surface of the ultrasonic vibrator array; three or more wiring boards electrically connected with the plurality of electrodes of the electrode section; and three ormore connectors to which a plurality of cables are individually connected. The three or more wiring boards are individually mounted to the three or more connectors and electrically connect the plurality of electrodes of the electrode section with the plurality of cables. The three or more connectors are arranged in the width direction of the backing material layer on the rear surface side of thebacking material layer.
Description
technical field [0001] The present invention relates to an ultrasonic vibrator unit, and more particularly to an ultrasonic vibrator unit having an ultrasonic vibrator wiring structure for realizing an ultra-small ultrasonic vibrator used in an ultrasonic endoscope inserted into a body cavity. 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, in addition to the ultrasonic observation unit, an optical sensor and an illumination unit are provided at the distal end of the ultrasonic endoscope as in conventional endoscopes without an ultrasonic observation unit. , air supply and water supply port and suction port. Therefore, the outer diameter of the distal end portion of the ultrasonic endoscope becomes thicker, which i...
