    摘要： An ultrasound transducer unit includes: a plurality of units each of which includes a piezoelectric element group, a wiring substrate that includes a plurality of wiring lines that are electrically connected to piezoelectric elements included in the piezoelectric element group, and a cable group that is electrically connected to the wiring lines included in the wiring substrate, that extends in a direction intersecting a longitudinal direction of each of the piezoelectric elements included in the piezoelectric element group, and that is formed into a helical shape; an outer surface support that supports, by using an outer surface of the outer surface support, the piezoelectric element group included in each of the plurality of units; and an inner surface support that supports an inner surface of the outer surface support. Cable groups included in the plurality of units constitute a multiple helical structure.

    摘要： An ultrasound transducer includes a transducer body configured to generate ultrasound vibration to vibrate a treatment portion that treats a living tissue. The transducer body includes a plurality of piezoelectric elements configured to alternately repeat expansion and contraction according to a supplied drive signal. The plurality of piezoelectric elements are integrally fastened in a state where the plurality of piezoelectric elements are stacked along a direction of expansion and contraction. The plurality of piezoelectric elements include a first piezoelectric element configured to expand at a first timing and contract at a second timing, and a second piezoelectric element whose expansion and contraction timings are different from expansion and contraction timings of the first piezoelectric element. The second piezoelectric element is arranged so that a polarization direction of the second piezoelectric element is a same as a polarization direction of an adjacent piezoelectric element.

    摘要： An endoscope bonding structure includes a distal end rigid member, a tubular body, and a bonding agent. The distal end rigid member includes a first outer diameter part and a second outer diameter part. The tubular body includes a first inner diameter part and a second inner diameter part. An outer diameter of an outer periphery of the second outer diameter part decreases as a distance increases toward a proximal end side. The tubular body is fitted to an outer periphery in a state in which the tubular body is pressed to a distal end side.
