6.2 Starting treatment
Only personnel who have been properly instructed in the handling of the ultrasonic
generator may begin treatment (see chapter
2.2 Selection and qualification of specialist
Handling the instrument
Always use the instrument with care to prevent damage to the sonotrode. Do not
bend the sonotrode or touch any metal objects with it.
The tissue effect is controlled primarily by ultrasonic power. Due to frictional heat, it is
also crucial for the outcome of treatment that the correct amount of pressure is ap-
plied to the tissue and that the sonotrode tip is moved correctly over the tissue.
Monitor the route of the instrument cable during the treatment. Personnel may not
be impeded. They could fall and patients be injured by the sudden movement from
the fall.
Ultrasonic power
It is crucial for the outcome of treatment that the power settings are correct. The
higher the ultrasonic power is set, the stronger the tissue effect.
If the ultrasonic power is set too high at the beginning of treatment it can have an un-
intentionally strong effect and severely injure the patient. Treatment should therefore
start at low ultrasonic power to prevent an unintentionally strong effect. Slowly in-
crease the ultrasonic power until the desired power is reached.
If the ultrasonic power is set too low, the tissue effect may be too weak. Adjust the ul-
trasonic power to achieve the desired tissue effect.
Irrigation flow
Irrigation flow that is set too low or too high may cause damage to tissue.
Do not set irrigation flow too low because this may cause tissue damage from over-
heating.
But also do not set irrigation flow too high, impeding a clear view of the tissue. Con-
tinuously monitor irrigation during treatment.
