Abstract: Based on the ANSYS software, the electric-thermal coupling simulation analysis was performed for the temperature field during the bipolar high-frequency electric knife being work. The influence of 4 different insulating layer materials and 4 different electrode materials on the temperature field of bipolar high-frequency electric knife was researched. The results indicated that, for the 304 stainless steel, 316 stainless steel, 317 stainless steel and Ti6Al4V, the electrode temperature is highest for choosing Ti6Al4V being the electrode material. And in 2 s for continuous power, the temperature of the insulating layer is close to the thermal deformation temperature of the insulating material, which leads to the softening of the insulating layer and affects the normal service performance of the electric knife. For the PA6, PC, PP and ABS, the latter two materials are more suitable for the manufacture of insulating layer of high-frequency electrical knife. The continuous power time for the high-frequency electric knife should not exceed 2 s, otherwise it will cause electrical burns to normal human tissue around the electrode.
