摘要:
A system and method for transmitting electro surgical energy from a generator to an electrosurgical instrument are provided. The electrosurgical system includes a generator adapted to generate electrosurgical energy for treating tissue. The generator includes one or more active output terminals which supply energy to the tissue. The active output terminals are operatively connected to one or more supply lines. The generator also includes one or more return output terminal which returns energy from the tissue. The return output terminals are operatively connected to at least one return line. The system also includes an electrosurgical instrument operatively connected to the one or more supply lines and one or more return electrodes operatively connected to one or more return lines. The system further includes an electrosurgical cable including one or more supply lines and one or more return lines. The one or more supply lines and one or more return lines are wound in a double helix fashion such that the electrical field along the cable is mitigated along the length thereof.
