The invention relates to an ultrasound emitting system (100) that comprises an essentially cylindrical body (6) as well as a piezoelectric assembly (1) inside said body for producing ultrasounds in the axial direction of said body, a sonotrode (2), a pre-tensioning bushing (3), and further comprising power supply and control means (60). The piezoelectric assembly comprises a stack of layers of a piezoelectric material, each layer being provided with excitation electrodes (18) and having a thickness of between 20 and 100 µm. The system is generally provided with a cannula (20) for the ultrasound treatment of a predetermined surface.
Système (100) d'émission d'ultrasons comprenant un corps (6) sensiblement cylindrique et à l'intérieur dudit corps, un ensemble piézo-électrique (1) pour produire des ultrasons suivant la direction axiale dudit corps, une sonotrode (2), une bague (3) de mise en précontrainte, et comprenant en outre un moyen d'alimentation électrique et de contrôle (60); ledit ensemble piézo-électrique étant constitué par un empilage de couches en matériau piézo-électrique, chaque couche étant munie d'électrodes d'excitation (18) et ayant une épaisseur comprise entre 20 et 100 µm. Le système généralement équipé d'une canule (20) permettant le traitement par ultrasons sur une surface déterminée
