Abstract
An ultrasonic medical probe comprises an elongate shaft formed integrally with a head portion having a distal end face oriented at least partially transversely to a longitudinal axis of the shaft. The shaft is provided with an internal longitudinal channel or bore extending to the end face. The end face is formed with an indentation communicating with the channel or bore at a distal end thereof, whereby liquid is guided over an extended surface of the end face relative to the channel or bore. The head portion also has a lateral surface extending substantially parallel to the longitudinal axis of the probe. The lateral surface is provided with at least one outwardly or radially extending projection. The projection enables the application of ultrasonic cavitation energy to a tissue surface that is in contact with the lateral or side surface of the probe head.
