ABSTRACT:
An ultrasonic wound cleaning device having an annular transducer, an axial bore extends through the annular transducer through which liquid admixed with modifying agents can flow towards a surface to be treated. A handle, a cleaning head, and a collecting cone are arranged respectively to the transducer so that cleaning liquid can flow through the axial bore, into the collecting cone, through the cleaning applicator head, where the liquid containing ultrasonic energy is brought into intimate contact with the wound and causes unwanted matter to be dislodged and washed from the wound and suspended in the liquid, and the loosened matter subsequently is flushed out of and away from the wound. The invention further comprehends preparation of human bone whereby joint replacement with a prosthesis can be carried out in a more sophisticated manner than has heretofore been possible.
