Abstract (en)

[origin: CA2664614A1] The invention relates to an ultrasound emitting system (100) that compris es 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 .mu .m. The system is generally provided with a cannula (20) for the ultrasound treatment of a predetermined surface.
