Ultrasonic surgery methods are widely used in modern medicine. One of the important parameters of ultrasonic oscillations is their amplitude, which measurement appears to be an urgent task. There are several methods in the ultrasonic oscillations measurement; they could be divided into those contact and contactless. Contact methods are making it possible to measure the amplitude in design, development, and creation of the ultrasonic oscillatory system, while the contactless could be introduced during its operation. The optical method is distinguished among those contactless methods. Its implementation requires only microscope, tripod and computer making the method accessible and easy to operate. Amplitude is measured at different generator power. Results of the experiment confirm that an increase in the oscillation generation power causes the increase in the working end oscillation amplitude of the ultrasonic oscillatory system also. Besides, a study was conducted to assess the effect of power and, accordingly, of the ultrasonic oscillations amplitude on the course of phonophoresis. Cavitation phenomenon is the theoretical basis for the ultrasonic oscillations effect on an increase in the biotissue cell membranes permeability. The conducted experiment confirmed that ultrasonic oscillations use increased the biotissue permeability, which could be applied in operations with medicinal substances introduction into the tissues.
