Study on the Energy Transmission of Simple Shape Amplitude Transformer

Ultrasonic surgery Is an effective treatment approach. It utilizes the ultrasonic energy to cure the morbid tissues. The deep research on the power ultrasonic surgical equipment can not only promote the development of relative technologies, but also relieve the suffering of patients. The method of the characteristic parameters of two ports mechanical network is applied to analyze the energy transmission performance of the simple shape amplitude transformer, such as stepped shape, exponential shape, conic shape and catenaries shape. Compared with conventional methods, this method not only calculates the resonant frequency, the amplification coefficient of vibration velocity and the mechanical impedance, but also takes the energy transfer performance into account. Therefore, it can ensure the energy transmission performance of the ultrasonic amplitude transformer within a large frequency range.
