Abstract:
Objectives:To establish a method of electric power detection and to evaluate its performance for ultrasonic harmonic scalpel(UHS).Methods:We defined maximum electric power(Pmax),static electric power(Pg) and spare power index(Pi) at first and worked-out reasonable procedure,then we designed available detecting-tools and determined the Pmax,Pg and Pi.Results:We detected 3 sets of UHS from domestic or overseas makers and acquired Pmax,Pg and Pi successfully.The results were stable,reproducible and positively correlated to ultrasonic power.Conclusions:The ultrasonic power of UHS is difficult to detect.By the experiment in this paper,detecting ultrasonic power can be replaced by detecting electric power.
