Description

[0001] The present invention relates to an ultrasonic fracture treatment apparatus,

The present invention relates to an ultrasonic fracture treatment apparatus, and more particularly, to an ultrasonic fracture treatment apparatus capable of expanding a use area of an ultrasonic wave for fracture treatment and infiltrating an ultrasonic wave corresponding to a fracture site at various positions, The present invention relates to an ultrasonic fracture treatment apparatus.

Generally speaking, sound waves below 30Hz are called "ultrasonic waves", sound waves above 20KHz, and sound waves that can not be heard by human ears. Ultrasound can not be heard in our ears, it is usually like a sound wave, it has the same acoustic and physical properties, and we can think that there are more ultrasonic waves in the air than all the sounds heard in the ear. Silent ultrasonic waves outside the human sensing range are already widely used in many applications.

Due to the realistic demands, it has recently been spotlighted as a cutting-edge technology. It can be applied to medical, military, and test equipment as well as industrial equipment in the surrounding area and can be used for processing, detection, position control, washing, welding, dust collector, inspection, , Cosmetics, bath, wash water, brushing, massage, and so on.

Particularly, it can be used as an acoustic detector used to measure the position of a ship or submarine or to measure the depth of the sea, communication between the ship and the ship, cleaning or sterilizing the corner with no hand, plastic gluing, ultrasonic metering, Ultrasonic sonography, that is, techniques for analyzing the reflected waves reflected from the inside of the body after emitting ultrasonic waves are becoming popular technologies.

Ultrasonic waves are vibrational acoustic waves with a vibration frequency of 17,000 Hz to 20,000 Hz or more, which are elastic waves generated by the vibration of an object, and have a piezoelectric effect. Ultrasonic treatment is usually performed using ultrasonic waves within 0.5 to 5 MHz. There is also some evidence that ultrasound can be used in fracture treatments to reduce bone fracture treatment time by as much as 40%.

Such ultrasonic waves have not been studied in depth of penetration into various parts of the human body, so they have been mainly used for diagnosis until now. Therefore, there is a need for research into expanding the system for treating fractures in ultrasonic therapeutic devices.
