Acoustical evaluation of ultrasonic horns for an endoscopic contact ultrasonic probe

Ultrasonic surgical aspirators has been applied in neurosurgery for several years, but some of the minor disadvantages limits its applications in general surgery. In order to eliminate major complaints, the endoscopic contact ultrasonic probe were constructed. During the construction process of the endoscopic contact ultrasonic probe, it was necessary to verify right choices between available technical solutions. This paper covers an experi-mental procedure that is applied in procedure of optimi-sation of resonant vibrating system. A possible choices of the specially shaped velocity transformers were mounted on the same ultrasonic transducer. The subharmonic emmision from ultrasonically irradiated media with every possible choices, were integrated over time, and the resultant signal is found to correlate with the electro-acoustical efficiency.
