ULTRASONIC SCALPEL CENTER FREQUENCY DYNAMIC ADJUSTMENT METHOD, AND ULTRASONIC SCALPEL

摘要

An ultrasonic scalpel center frequency dynamic adjustment method, and an ultrasonic scalpel. The method comprises the following steps: S1, when power-on, presetting a bandwidth and a center frequency according to the properties of an ultrasonic scalpel handle vibration system, and calculating a sweep frequency range; S2, performing frequency sweep to obtain the start resonance frequency of the ultrasonic scalpel handle vibration system; S3, setting the start resonance frequency as a new center frequency, and obtaining a new resonance frequency range; and S4, starting to work from the new center frequency, and performing resonance frequency tracking. According to the method, the optimal resonance frequencies of inserted shafts is allowed to be inconsistent, the optimal frequency swept by the ultrasonic scalpel can be used as the working frequency, shafts of different types and designs can be replaced during use, and each type of shaft is allowed to produce a better effect. In addition, the method enhances the adaptability of an ultrasonic scalpel, and solves the problems of complicated frequency sweep operation and unreasonable frequency sweep design, for example, occurrence of shaft bending and breaking.
