Abstract
An ultrasonic treatment apparatus includes an ultrasonic vibration generating portion for generating ultrasonic vibrations, an amplifying portion for amplifying the ultrasonic vibrations generated by the ultrasonic vibration generating portion, a vibration transmitting member for transmitting the ultrasonic vibrations amplified by the amplifying portion, and a connecting member for connecting the vibration transmitting member to the amplifying portion such that the central axes of the vibration transmitting member and of the amplifying portion intersect at a predetermined angle. The generated ultrasonic vibration includes nodes and loop portions between adjacent nodes, and both a connecting portion between the connecting member and the amplifying portion and a connection portion between the connecting member and the vibration transmitting member are formed in the vicinity of a position at which a loop portion of the ultrasonic vibration lies.
