The 55.5KHz ultrasonic scalpel transducer is an energy device that converts electrical, mechanical, or sound energy from one form of energy to another, also known as an ultrasonic transducer or active sensor. The mature and reliable device among them is a piezoelectric transducer, also known as a device that converts electrical and acoustic energy through the piezoelectric effect. The ultrasonic transducer is composed of a central piezoelectric ceramic component, front and rear metal cover plates, pre-stressed screws, electrode plates, and insulating tubes. Ultrasonic transducers are almost applied to all ultrasonic equipment.
