Specifically, the electrode tip 42 may be of the following types: knife-shaped tool bits, needle-shaped tool bits, spherical tool bits, annular tungsten filament tool bits, triangular tungsten filament tool bits and the like, but other types of electrode tool bits can also be adopted. After the different types of electrode tips 42 are combined with the hollow pencil sharpener 41, a knife-shaped electrode tip structure (as shown in fig. 3), a needle-shaped electrode tip structure (as shown in fig. 4), a ball-shaped electrode tip structure (as shown in fig. 5), an annular tungsten wire electrode tip structure (as shown in fig. 6), and a triangular tungsten wire electrode tip structure (as shown in fig. 7) are sequentially formed.

The electrode tip structure 4 of this embodiment is detachably connected to the front end of the hollow electrode shaft 3, i.e. the electrode tip structure 4 can be connected to the front end of the hollow electrode shaft 3, or can be detached from the hollow electrode shaft 3. Therefore, when the doctor needs to use the electrode tip 42 having a different shape, the electrode tip structure 4 is simply detached from the hollow electrode shaft 3 and replaced with a desired electrode tip structure. Meanwhile, as the hollow pencil sharpener sleeve rod 41, the hollow electrode rod 3 and the suction tube 2 of the electrode cutter head structure 4 are all hollow structures, namely, a smoking channel is formed inside, during specific operation, a negative pressure aspirator is connected to the tail end of the suction tube 2, and then the smoking channel is combined, so that smoke generated in the operation process can be sucked out. Therefore, the operation electrode of the embodiment has the functions of smoking and replacing the electrode head at the same time.
