Assessment Of The Titanium Wire As A Endoscopic Surgical Tool

During scientific-research programmes in the Republic of Croatia, a possibility to apply high-power ultrasonic point sources for minimally invasive neurosurgery has been noticed. Earlier experiences with applications of high energy ultrasound have induced the idea of ultrasonic energy transfer through an elastic wire waveguide. The scope of this study is to present the results of theoretical and experimental research in the field of generation and propagation of high-power ultrasound along the titanium wire as a endoscopic surgical tool. On the basis of the theoretical calculations for generation and transmission of ultrasonic waves from the ultrasonic transducer, through the mechanical concentrator to the endoscopic tool, the ability for adaptation to different surgical applications have been described. In the experimental part, methods for verification of the theoretical results have been presented. This includes methods for validation the performance of the 1, 6 mm titanium wire as an endoscopic tool and experimental methods for assessment of electric and acoustic characteristics.
