Title:
BOLTED ULTRASONIC VIBRATION TRANSDUCER
Document Type and Number:
Japanese Patent JP3514506
Kind Code:
B2
Abstract:
PURPOSE: To improve the operability and visual field, of an ultrasonic operating instrument contg. a bolted ultrasonic vibration transducer by reducing the diameter on the front part side of this operating instrument.
CONSTITUTION: This ultrasonic vibration transducer is provided with a first difference in level 102 in the position of a node A of the first vibration displacement on the front side from a piezoelectric element 10 and is provided with a second difference in level 104 in the position of the node B of the second vibration displacement. Amplitude is increased and the diameter of the operating instrument is made gradually smaller by the differences in level and, therefore, the operability is improved and the visual field is assured.
