| Abstract: | The S-matrix analyzing method is employed in this paper for the analysis of a power ultrasonic transducer system. An optimal algorithm is introduced in the design of the system to avoid the inaccuracy caused by approximate modeling in traditional design and the complexity of manual adjustment and testing in the process of hardware design. The experimental result is in comply with the theoretical analysis. The designed ultrasonic surgical instrument based on this is of good performances and has been used in clinical practice. |
