Návrh a pevnostní kontrola pracovní části radiofrekvenčního operačního nástroje

Abstract

The goal of this work is design and construction of the tool for radiofrequency ablation, which would further specify the lead of electrodes into the liver tissue, reduced operating time to a minimum, not damage healthy tissue unnecessarily in the vicinity of the tumor and would be compatible with the currently used radio-frequency power source from the company named RITA. Bachelor's thesis can be divided into theoretical and practical part. The theoretical part is focused on liver and liver tumors. There is described the technique of radio-frequency ablation of liver tumors. The practical part is divided into two chapters. The first part deals with the deployment of the electrodes in the operating instrument and their shape and design of the instrument, its subsequent production and testing at the University Hospital in Ostrava-Poruba. The second chapter focuses on strength and buckling analysis. This part of the solution has been done by software Ansys.
