Abstract
A system to be used for transmitting ultrasonic vibration, the system including a sonotrode designed to vibrate in a stationary wave having at least one node position between the distal end and the proximal end of the sonotrode, and a guide shaft with a through opening. During operation the sonotrode extends through the through opening of the guide shaft and the distal end of the guide shaft is situated on a distal side of the most distal node position of the sonotrode. The sonotrode and the guide shaft are adapted to each other for radial clearance between the sonotrode and the guide shaft to be a minimum for a sonotrode portion comprising the most distal node position.
