Abstract
A plasma surgical electrode and instrument are provided. The plasma surgical electrode includes an electrode head, an electrode stem, and an electrode interface that are connected in sequence, where the electrode stem includes a conductive inner layer, an insulating inner layer, and a conductive outer layer that are arranged in sequence from inside to outside; the conductive inner layer is electrically connected to a working electrode of the electrode head and the electrode interface; and the conductive outer layer is electrically connected to a loop electrode of the electrode head and the electrode interface. The electrode stem is in a single-tube form, which is not easily twisted or deformed and moves smoothly with the endoscope during the surgical process, avoiding problems such as unevenness and bleeding during cutting.
