Abstract
Horn is one of the main components of ultrasonic cutting systems. The most important characteristics of the horn design are its resonant frequency and amplification factor. Closed-form equations can be used only for the design of simple horns and do not apply to more complex shapes like surgical tools. This paper presents a designing technique based on the finite element method and experimental tests. It can improve conventional design methods and facilitate designing a high performance surgical ultrasonic horn for bone cutting tools. The new and complex bone cutting tool has both the knife-edge and toothed-edge which could cut the bone easily and accurately. The investigations of cutting forces applied to the tool edges show less force in the toothed edge than the knife edge.
