The Use of Ultrasonic Transducers in Medical Treatment

Ultrasonic transducers emit ultrasonic waves, which can also be called mechanical waves. It has good directionality and strong penetrating ability, and it can spread in water and air. It can be used for distance measurement, speed measurement, cleaning, welding, stone crushing, sterilization, disinfection, etc. The transducers commonly used in ultrasound are divided into magnetostrictive transducers and electrostrictive transducers according to the vibration excitation mode.

Ⅰ. The historical development of the medical ultrasonic transducer

 

At the beginning of the 20th century, the development of electronics enabled people to use the piezoelectric effect and magnetostrictive effect of certain materials to make various electromechanical transducers. In 1917, French physicist Langevin used natural piezoelectric quartz to make a sandwich medical ultrasonic transducer and used it to explore submarines on the sea floor. With the continuous development of ultrasonic applications in various sectors of the military and national economy, magnetostrictive transducers with greater ultrasonic power have emerged. In addition, there are various electric, electromagnetic, and electrostatic ultrasonic transducers for different purposes.

 

Ⅱ. The medical uses of the ultrasonic transducer are as follows:

 

1. The medical use of medical ultrasound transducers is mainly divided into two parts: medical testing and treatment.

 

2. Common medical instruments such as B-ultrasound, color Doppler ultrasound, ultrasonic holographic imaging technology, ultrasonic scalpel, and ultrasonic stone breaking technology in hospitals all use medical ultrasonic transducers to work.

 

3. Ultrasonic transducers are used in different medical devices, so their uses are also different. Because ultrasound is harmless to the body, it is also widely used in medical treatment.
