Electrode scalpel head and plasma scalpel

The utility model relates to an electrode tool bit and a plasma scalpel, and belongs to the technical field of medical instruments. The plasma scalpel comprises a handle and an electrode scalpel head, the electrode scalpel head comprises a fixing tube, a working catheter and an electrode assembly, and the working catheter is arranged in the fixing tube in a sliding and penetrating mode and can stretch out of the front end of the fixing tube; the electrode assembly and the working catheter form double poles; a bending part is arranged at the front end of the fixed pipe, the bending angle of the bending part is 25-50 degrees, a bendable deformation section is arranged at the front end of the working guide pipe, and the deformation section corresponds to the bending part. According to the electrode scalpel head and the plasma scalpel, the length of the electrode scalpel head can be adjusted, due to the fact that the fixing pipe is bent and can be bent along with deformation in the stretching and retracting proce
