Abstract
A curved ultrasonic knife consisting of a transducer unit (5) and an amplitude-amplifying horn connected directly thereto, the knife being shaped to imbue the tip (43) of the horn with, to a great extent, purely longitudinal oscillation. The transducer unit includes a piezoelectric unit axially clamped in the transducer unit (5). A resonance rod (28) located between the piezoelectric unit and the horn (2) is bent to give a deflection of 16.degree., for example.
