An ultrasonic orthopaedic surgical device based on a cymbal transducer.
An ultrasonic orthopaedic surgical device is presented, where the ultrasonic actuation relies on a modification of the classical cymbal transducer. All current devices consist of a Langevin ultrasonic transducer with a tuned cutting blade attached, where resonance is required to provide sufficient vibrational amplitude to cut bone. However, this requirement restricts the geometry and offers lit...
متن کاملOptimisation of a cymbal transducer for its use in a high-power ultrasonic cutting device for bone surgery
The class V cymbal is a flextensional transducer commonly used in low-power ultrasonic applications. The resonance frequency of the transducer can be tailored by the choice of end-cap and driver materials, and the dimensions of the end-caps. The cymbal transducer has one significant limitation which restricts the operational vibration amplitude of the device. This is the limit imposed by the me...
متن کاملMotivating the Marching Cymbal Line
it is the instructor’s responsibility to instill a positive attitude and set high expectations for all members, while helping students grow and become better musicians. If difficulty is the modern measuring stick for superiority, then one can certainly argue that multi-tenors are the most challenging instrument to play, while others will say the bass drum requires the most demanding skill. Alth...
متن کاملTransducer design simulation using finite element method
The fast development of computer power and computational algorithms has made it possible to design complex transducers and arrays using computer simulation. Practical examples are given here for transducer modeling using 3-D finite element method (FEM) instead of the traditional 1-D equivalent circuit models. The merits and deficiencies of the frequency domain and time domain FEM formulations w...
متن کاملDynamics characterisation of cymbal transducers for power ultrasonics applications
A class V cymbal flextensional transducer is composed of a piezoceramic disc sandwiched between two cymbal-shaped shell endcaps. Depending on the type of piezoceramic, there exists a maximum voltage that can be reached without depolarisation, but also, at higher voltage levels, amplitude saturation can occur. In addition, there is a restriction imposed by the mechanical strength of the bonding ...
