Abstract:
1. An ultrasonic treatment probe that is configured to transmit an ultrasonic vibration from a proximal direction toward a distal direction along a longitudinal axis, the ultrasonic treatment probe comprising: a multiple-members vibrating portion that includes a plurality of coupled vibration members, each of the coupled vibration members extending in a lengthwise direction along the longitudinal axis, and each of the coupled vibration members having an inner surface, wherein a groove is formed in the lengthwise direction along the longitudinal axis by the inner surface in each of the coupled vibration members, the coupled vibration members being coupled to each other when the inner surface of each of the coupled vibration members face each other, such that a passage extending from the proximal direction toward the distal direction is formed inside the multiple-members vibrating portion; and the multiple-members vibrating portion is configured to transmit the ultrasonic vibration such that each of the coupled vibration members vibrates in a same vibration mode, and such that a first anti-node position of the ultrasonic vibration is located at a proximal end of the multiple-members vibrating portion, and a second anti-node position of the ultrasonic vibration is located at a distal end of the multiple members vibrating portion.
