Ultrasonic piezoelectric converter for surgical eliminator

Piezoelectric converters used in medical ultrasonic installations are as a rule, compound framed structures. It is supposed that there are no point loads between the units of the structure. At the end of the last unit there can be point load of any kind. Compound framed structures are inhomogeneous ones. Heterogeneity can be considered as the place inside the structure, where this structure is loaded to the non-wave resistance. Thus, if there are a lot of heterogeneities and they are divided over the structure according to the random law many reflected waves occur laid on each other and disturbing oscillating mode of the structure.
