The novel bipolar electric snare comprises a
slip ring, an inner sheath tube, an outer sheath tube, a large reed and an
electrode plug, the outer sheath tube is sleeved on the inner sheath tube, one end of the outer sheath tube close to a snare
electrode is provided with a fixed terminal, and one end of the fixed terminal away from the snare
electrode is connected with a loop electrode ring. A loop electrode wire is arranged in the loop electrode ring in the length direction of the loop electrode ring, the large reed is electrically connected with the loop electrode wire, the lower end of the electrode plug is connected with a small reed in a pressing mode, the inhaul cable transversely penetrates through the small reed, and the small reed is electrically connected with the inhaul cable. The electrode plug is connected with the inhaul cable, so that when high-frequency and high-
voltage current of a main
machine is in contact with a
human body through the snare electrode, the current generates a
heat effect at the tissue to heat the tissue, separation and solidification of the tissue of the
human body are achieved, and the purposes of
cutting and
hemostasis are achieved. High-frequency and high-
voltage current flows back to the main
machine through the fixed terminal, the loop electrode ring, the loop electrode wire and the large reed to form a
closed loop.
