Ultrasonic Knife Applications: 

Ultrasonic waves have good directionality, strong penetrating ability, easy to obtain more concentrated sound energy, and far-reaching distance in the water. Theoretical studies have shown that under the same amplitude, the energy of an object is proportional to the vibration frequency. When the ultrasonic wave propagates in the medium, the frequency of the vibration of the medium particle is very high, so the energy is very large, and the huge energy of the ultrasonic wave can also make the stones in the human body are broken and severely forced to vibrate, thereby slowing down the pain and achieving the purpose of healing.

Standard Size of Piezo Ring:

External diameter: 5.0 - 100mm
Internal diameter :(2.0 - 35mm)
Thickness : (0.2 - 15mm) 

 

PZT Material:

 

- PZT4 Piezoelectric ceramics have a double behavior of receiving and transmitting, with higher sensitivity and lower dielectric loss.

- PZT5 Piezoelectric ceramics have higher electro-mechanical coupling coefficient, the moderate dielectric constant and higher sensitivity.

- PZT8 Piezoelectric ceramics of high power transmission type have good piezoelectric property, high mechanical strength, high coercive field, low dielectric loss in strong fields.
