摘要： A puncture adapter is provided for being mounted on an ultrasonic probe. The ultrasonic probe to be mounted comprises a rod-like insertion portion that is insertable into a subject and has a search unit for transmitting and receiving ultrasonic waves at the tip end of the insertion portion, and in which a guide channel for guiding a puncture needle is formed on a side surface of the insertion portion. This puncture adapter has a first tubular component on which a gap is provided on a side surface along the length direction, which gap is from one end to the other side of the side surface. The first tubular component is mounted so as to contact the outside of the insertion portion and cover the guide channel, and is turnable in the circumferential direction thereof.

摘要： An ultrasonic probe includes ultrasonic piezoelectric elements that are arranged in a first direction at predetermined intervals and transmit and receive ultrasonic waves in a second direction substantially orthogonal to the first direction. The respective ultrasonic piezoelectric elements have plural grooves, which are parallel to the first direction and do not pierce through an end face, on at least one end face of two end faces substantially orthogonal to the second direction of the respective ultrasonic piezoelectric elements. The ultrasonic waves are weighted in a third direction orthogonal to the first direction and the second direction according to shapes and arrangement of the respective plural grooves and transmitted and received. In addition, a conductive member is joined to the end face having the grooves of the respective ultrasonic piezoelectric elements along the third direction.

摘要： A generating unit generates a polurality of ultrasonic cross-sectional images at a plurality of angles when an ultrasonic wave emitting surface in an ultrasonic probe is rotated. A regenerating unit saves information on the angle of the ultrasonic wave emitting surface when a predetermined condition is satisfied, and rotates the ultrasonic wave emitting surface from the angle of the ultrasonic wave emitting surface different from the saved angle information to the angle based on the saved angle information.
