    Abstract: A treatment device includes a support section having conductivity, for which a separate position separated from the probe is switched to a support position at which the support section abuts the probe to support the probe when bent in a direction off of the central axis in accordance with a load which is applied to the probe, and subserviently moved with the vibration of the probe. The support section absorbs the vibration transmitted in the probe when the support section is at the support position.

    Abstract: An ultrasonic treatment apparatus includes a probe main body performing a vibration including a longitudinal vibration in a vibrating direction parallel to a longitudinal axis, and a distal treatment section positioned on a distal direction side with respect to a most distal node position positioned most distally among node positions of the longitudinal vibration in the probe main body. A probe side facing surface is provided in a position facing a jaw in a surface of the distal treatment section. A coating portion is made of a material having a higher heat resistance than the probe main body, and coats a surface facing a side opposite to the probe side facing surface in the probe main body.

    Abstract: 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.
