BBT Ultrasonic Transducer

Wuhan BBT Medical is a professional ultrasonic transducer supplier and manufacturer. Our homemade ultrasonic transducer is a device that converts electrical energy into mechanical energy, usually made of piezoelectric ceramic sheets. The piezoelectric effect of the material converts electrical signals into mechanical vibrations. The electric oscillation signal from the excitation power supply will change the electric field in the energy storage element of the ultrasonic transducer, causing it to enter a vibration state, thereby driving the medium in contact with the mechanical vibration system of the transducer to vibrate. When the vibrating blade is in contact with the tissue, it will break the protein hydrogen bonds of the tissue, and the tissue protein cells will be denatured to form a sticky clot, which can cut hemostasis (vessels below 5mm).

How Does An Ultrasonic Transducer Work?

The ultrasonic transducer itself is not an energy generator, it is just an energy converter, which converts electrical energy into mechanical energy, and can convert a large amount of energy on the premise that the output matches the input well. A high AC voltage is applied to the transducer through the drive circuit to charge and discharge the capacitance of the transducer. Among them, the piezoelectric ceramic sheet undergoes simultaneous expansion and contraction under the action of an alternating electric field, generates longitudinal mechanical vibration and expands at the conduction shaft node. The bite force of the cutter head can reach the maximum 55.5KHz high frequency vibration. The cutter head contacts the tissue protein, breaking the hydrogen bond of the protein, reorganizing the protein structure, and deep coagulation to close the larger lumen, so as to achieve the effect of cutting, coagulating the tissue and stopping bleeding.
