Beschreibung
Zusammenfassung:An ultrasound emission system comprising a substantially cylindrical body and, inside said body: a piezoelectric assembly for producing ultrasound along the axial direction of said body, a sonotrode assembly, a prestress ring, and further comprising electrical power supply and control means; said piezoelectric assembly being constituted by a stack of layers of piezoelectric material, each layer being provided with excitation electrodes and presenting thickness lying in the range 20 mum to 100 mum. The system, generally fitted with a cannula enabling the ultrasound treatment to be applied to a determined area, can itself be incorporated in such a manner as to make an ultrasound treatment machine serving in particular to perform phacoemulsification.
