A method is furnished for a treatment of septic wounds. A hand piece of a sonotrode
is connected to a liquid storage. Access to a wound is furnished to the sonotrode.
A liquid atomized by ultrasound is delivered to the wound through a sonotrode channel
disposed in the sonotrode. Bacteria in the area of the wound are destroyed by the
ultrasound emitted by the sonotrode. The method allows to remove a prosthesis not
longer desired from a patient. The area left open by the removed prosthesis and/or
a bone is filled with a liquid. The sonotrode is then entered into the liquid for
propagating ultrasound through the liquid and thereby destroying bacteria present
in the liquid.
