An ultrasonic surgical aspirator having a transducer supported in a handpiece for generating ultrasonic vibrations which are transmitted to the tip of an operative probe through a transmitting structure including an elongated slender portion which is curved along at least a portion of its length to displace the longitudinal axis of the handpiece from the longitudinal axis of the probe attached to the end of the slender portion of the transmitting member to permit unobstructed vision along the probe. The radius of curvature of the curved portion of the transmitting structure is equal to or greater than 0.7 times the length of the longitudinal waves being transmitted.
