Abstract

Applications of the electrosurgery for dissection have been investigated widely. This new technology is necessary for the development of surgical device in order to decrease the thermal damage around the tissue. The purpose of the study is to prevent the thermal energy from focusing on the part of the tissue by surface treatment of nano-chromium nitride (CrN) film on the invasive microsurgery device. The results of this study (the electrosurgery), could promote the thermal conduction by the surface treatment method. Depending on different treatment skills, which could create many kinds of surfaces and these new surfaces could increase about the 10% to 20% area on the substrate. The maximum temperature could effectively decrease 8% by using electrode with surface treatment and the volume of hurting tissue decreased about 2%. There are two points which could decrease the thermal damage. Firstly, through surface treatment, it could increase the surface area and secondly, the electric resistivity of the chromium nitride is low, so it could promote the conductive speed. Both of these could achieve thermal homogeneous diffusion successfully. The mechanism of surface treatment in microsurgery application could promote the thermal conductivity, and expected to benefit greatly on the clinical application. Surface treatment could enhance the microsurgery efficiency on the clinical application.
