中文摘要	In this paper we present a new method to optimize ultrasonic surgery tools, which is characterized by integrating Finite Element Method, Analytical Method and Constrained Variable Method. In our optimization process, the optimization aim is output power of the surgery tool, which is the most important parameter to value performance of ultrasonic surgery tool and could be achieved by the product of impact force at the tip of the ultrasonic tool and vibration velocity amplitudes. Design variables are dimensions of certain part of the tool, constrain functions are stresses of the stress-concentration zone; Optimization results showed that compared with the given initial parameters, the velocity of the optimum parameters was dramatically increased. Experiments were also performed and the results were in great agreement with the theoretical one.
