上海超声波仪器厂新近研制成功的CJY-3型超声波洁牙器是一种防治结合的口腔手术器械,它是大规模开展牙周病防治所不可缺少的新颖器械。CJY-3型超声波洁牙器利用换能器中晶片所产生的超声振动(约30,000—34,000次/S),通过聚能杆集中在工作刀具端部。当工作刀具轻轻地接触齿面来回摩擦触及牙垢或结石时,就能迅速粉碎剥离,并由喷出的水流带 Shanghai Ultrasound Instrument Factory recently successfully developed CJY-3-type ultrasonic scaler is a combination of prevention and treatment of oral surgical instruments, it is large-scale prevention and treatment of periodontal disease is indispensable new instruments. The CJY-3 ultrasonic scaler uses ultrasonic vibrations (about 30,000-34,000 shots / s) generated by the wafers in the transducer and is concentrated on the working tool tip by the beam concentrator. When the work tool gently touches the tooth surface back and forth rubbing touch calculus or stones, it can quickly smash stripping, and by the jet of water flow
