Title:
ULTRASOUND APPARATUS AND OPERATING METHOD
Document Type and Number:
Japanese Patent JP2012081288
Kind Code:
A
Abstract:
To provide a reliable ultrasonic hand piece which vibrates in both of a vertical maneuver and a twisting maneuver simultaneously or separately without using a piezoelectric crystal.
The ultrasonic handpiece includes a magnetorestrictive stack 210, a horn 220 for ultrasonic wave which is attached to the stack while including a plurality of slits 260, and an electric coil 250 which surrounds the stack adapted for receiving a drive signal. The plurality of slits have enough size and space to generate a twisting motion in the horn in response to the drive signal with a first frequency and generate a vertical motion in the horn in response to the drive signal with a second frequency.
