Abstract

THERE IS AN INCREASING DEMAND FOR ULTRASONIC SURGICAL KNIFES, DUE TO THE SEVERAL ADVANTAGES OF THESE SYSTEMS IN RELATION TO THE CONVENTIONAL KNIFES. THIS STUDY DEALS WITH THE DESIGN, OPTIMIZATION AND FABRICATION OF AN ULTRASONIC SURGICAL KNIFE TO EXTEND THE TECHNOLOGY AND APPLICATION OF THESE SYSTEMS. THE GENERAL DESIGN OF THE SYSTEM WAS PERFORMED CONSIDERING THE DIFFERENT DESIGN CONSTRAINTS AND PARAMETERS. THE FINITE ELEMENT METHOD (IN ANSYS ENVIRONMENT) WAS EMPLOYED TO SIMULATE THE PIEZOELECTRIC BEHAVIOR AND MODAL ANALYSIS OF THE TRANSDUCER AND OBTAIN ITS OPTIMAL DIMENSIONS. FOLLOWING THE FABRICATION OF A PROTOTYPE, NATURAL FREQUENCY AND IMPEDANCE OF THE TRANSDUCER WERE MEASURED USING NETWORK ANALYZER. THE RESULTS INDICATE THAT THE FINITE ELEMENT METHOD IS AN EFFECTIVE TOOL FOR DESIGN OF ULTRASONIC TRANSDUCERS AND CAN PREDICT THE NATURAL FREQUENCY BY A 10% ERROR. THE PRIMARY APPLICATION TESTS ON THE PROTOTYPE, SUGGEST THAT IT HAS A GOOD PERFORMANCE FOR EASY AND EFFECTIVE CUTTING OF MATERIALS AND TISSUES.
