ANTI-FATIGUE DESIGN OF ULTRASONIC BONE CUTTER BASED ON FINITE ELEMENT METHOD

For ultrasonic bone cutters used in precise bone surgery, reliability and life is especially important because patient’s life is priceless. To solve the crack problem of ultrasonic saw cutter, reasons of crack are analyzed. Stress decentralization measures are taken to optimize the structure of ultrasonic bone cutter, FEA (Finite Element Analysis) method is used to analyze stress distribution before and after structure improvement. Life of bone cutter is measured by statistical experiments, which shows after structure improvement, the total working time of the bone cutter is 7 times longer than the original structure.
