1. An ultrasonic probe comprising:
a probe main body portion which extends along the longitudinal axis with the longitudinal axis being an axial center, and which is configured to transmit an ultrasonic vibration along the longitudinal axis from a proximal direction toward a distal direction; and a probe bend portion which is provided on the distal direction side with respect to the probe main body portion, when one direction perpendicular to the longitudinal axis is set to be a first bend direction and an opposite side to the first bend direction is set to be a second bend direction, the probe bend portion bending relative to the probe main body portion in the first bend direction and the second bend direction in a state in which a center of gravity is located on a first bend direction side with respect to the longitudinal axis, the probe bend portion being configured such that, when one side of a direction, which is perpendicular to the longitudinal axis and is perpendicular to the first bend direction and the second bend direction, is set to be a first perpendicular direction and an opposite side to the first perpendicular direction is set to be a second perpendicular direction, a cross-sectional shape of the probe bend portion in a cross section perpendicular to the first perpendicular direction and the second perpendicular direction varies continuously along the first perpendicular direction and the second perpendicular direction in a state in which a cross-sectional center of gravity of the probe bend portion in the cross section perpendicular to the first perpendicular direction and the second perpendicular direction lies toward the second bend direction side, as it is from the first perpendicular direction toward the second perpendicular direction. |
