This invention relates to a bipolar adjustable plasma electrode, comprising: an electrosurgical head; two first tubes, the electrosurgical head spanning between the two first tubes, and the first tubes containing a high-temperature resistant wire that is in contact with and conductive to the electrosurgical head; a second tube connected to the end of the two first tubes away from the electrosurgical head, and the first and second tubes being rotatably coupled; and a third tube containing a phosphor bronze rod, the phosphor bronze rod being electrically connected to a plug via a cable. Only a brief energization of the heating wire is needed to melt the phase-change conductive material, allowing easy adjustment of the angle between the two first tubes, thereby changing the shape of the electrosurgical head to adapt to different anatomical sites or surgical approaches. The frictional force between the first and second tubes maintains the shape of the electrosurgical head in the absence of external force. After power is cut off, the phase-change conductive material rapidly solidifies, locking the relative positions of the high-temperature resistant wire and the phosphor bronze rod.
