Abstract: Apparatus for ultrasonically removing biological tissue using an axially vibrating probe, and method of making same, including a housing having an outer portion forming a handle, wherein the housing has a sleeve therein supporting a piezoelectrical transducer with planar piezoelectrical elements arranged in parallel relation with an axis of the probe. An armature is provided which operatively connects the probe with the piezoelectrical elements, wherein the piezoelectrical elements are arranged between outwardly facing sides of the armature and inwardly facing sides of filling bodies inserted in the sleeve, respectively. An intermediate layer of electrically conductive foil is located between the piezoelectrical elements and the outwardly facing sides of the armature and the inwardly facing sides of the filling bodies, respectively.
