Design of Amplitude Bar for New-type Medical Ultrasonic Debridement Instrument

Objective To develop a new type of medical ultrasound debridement instrument and the amplitude bar. Methods According to the specific requirements of the debridement instrument, the electronic design techniques were adopted to determine the sound intensity threshold, oscillation amplitude and near-filed distance.Results The amplitude bar could meet all kinds of technical requirements, and the titanium alloy raw materials made it corrosion-resistant and anti-fatigue. Conclusion The amplitude bar adapts well to the debridement instrument, and other medal materials also can be adopted according to different requirements.
