Title:
ULTRASONIC IRRADIATION APPARATUS FOR FACILITATING NATURAL DEGENERACY OF INTERVERTEBRAL DISK HERNIA
Document Type and Number:
Japanese Patent JP2005052523
Kind Code:
A
Abstract:
To provide an ultrasonic irradiating apparatus for facilitating natural degeneracy of the intervertebral disk hernia.
The apparatus is for reducing the period of time of natural degeneracy of the intervertebral disk hernia by irradiating ultrasonic waves. The apparatus comprises at least one ultrasonic transducer, an ultrasonic transmitter, and a means for mounting the ultrasonic transducer on a joint region. The apparatus irradiates ultrasonic waves whose frequency is 1.3-2 MHz, cycle period is 100-1,000 Hz, burst width is 10-2,000 μs, and output is not more than 100 mW/cm2 (on SATA:Spatial Average-Temporal Average).
