Operation Preparing for treatment
5.1 Preparing for treatment First the UAW handpiece must be connected to the ultrasonic generator. A visual inspection must then be carried out. Finally, functional testing must be carried out and the power settings on the ultrasonic generator checked. Only then may treatment be started.
5.1.1 Connecting the UAW handpiece to the ultrasonic generator Requirements
The UAW handpiece is sterile.
The instrument cable is sterile.
An irrigation bottle and a sterile irrigation tubing are at hand.
The ultrasonic generator is turned on.
Procedure 1. During a visual inspection, ensure that the handpiece body, the sonotrode and the nose cone are in perfect condition.
Liquid on the contacts The connector socket may melt due to liquid on the contacts of a connector socket or the instrument cable. This leads to malfunctions of the UAW handpiece and of the ultrasonic generator. Treatment must be carried out with a redundant system, thereby lengthening the treatment duration.
Make sure that the contacts on the connector sockets and on the plug connectors are dry before connecting.
Observe the specified sequence of the steps so no liquid gets onto the contacts.
2. Insert the instrument cable plugs into the connector socket on the ultrasonic generator. Observe the markings. – The instrument cable engages in the connector socket.

Operation Starting treatment
5.2 Starting treatment A single foot switch on the ultrasonic generator is used for activating the ultrasonic power. If an ultrasonic generator with irrigation is used, irrigation is activated at the same time. UAW handpieces are available with different sonotrodes. The sonotrode tip may have a double-ball, hoof or spatula form. Select the suitable UAW handpiece. It is crucial for the treatment result that the power settings are correct, in particular for the ultrasonic power. The treatment effect is controlled primarily with the ultrasonic power. The higher the ultrasonic power is set, the stronger the treatment effect. Always begin the treatment with a low ultrasonic power to prevent an unintentionally strong effect. Then slowly increase the ultrasonic power. For the desired treatment effect to be achieved with the UAW handpiece, irrigation solution must be used. Begin the treatment with a little irrigation solution. In most cases, the preset irrigation capacity with a quantity of 6 ml/min is sufficient. During the treatment, continuously check that solution is directed to the sonotrode tip so the sonotrode tip does not clog or heat. Due to the friction heat, it is also crucial for the treatment result that the correct pressure is applied to the tissue and the movement of the sonotrode tip is correct over the tissue. Always use the UAW handpiece with care so the sonotrode is not damaged. Do not bend the sonotrode or touch any metal objects with it. Observe the course of the instrument cable and the irrigation tubing during the treatment. The staff must not be impeded. They could fall and patients be injured by the sudden movement from the fall.
Contaminated UAW handpiece Use of a contaminated UAW handpiece may result in life-threatening infections in both patients and users.
18
Only use a sterile UAW handpiece.
Only use a sterile instrument cable.
Only use sterile irrigation tubing from undamaged packaging.
