摘要： A surgical system (10) has a multiple electrode electrosurgical capability in combination with a gas plasma capability for delivery of electrosurgical energy to the tissue (14) or bodily fluids (15) of a patient (16). The system includes a holder (17), a source of electrical energy (20), electrodes connected to the source of electrical energy (20), one or more passages (22) carried on the holder (17) for transporting ionizable gas (23), and a source of ionizable gas (24) of a selectable flow rate. The gas passages (22) may include at least one electrode extending toward the operative site. The gas passages (22) may include a part (28) that creates a vortex in the gas flow. The electrodes may be coaxially placed in the gas passages (22). The system may also be configured such that two electrodes are each shrouded by the ionized gas so that the electrosurgical energy is conducted to the tissue (14) or bodily fluids (15) of the operative site by passing along conductive pathways (25) in the ionized gas from each electrode. There may also be a dielectric barrier (26) between the conductive pathways (25). The system may also be configured such that one of the multiple electrodes (11) is substantially in contact with the tissue (14) or bodily fluids (15) of the operative site and another of the multiple electrodes (11) is in the circuit through the conductive pathway of the ionized gas flow so that electrosurgical energy is conducted through the tissue (14) or bodily fluids (15) of the operative site and between the electrodes. Methods of manufacture and use for the system are also claimed.
