Abstract: An apparatus and method for igniting plasma in a surgical system is disclosed. A corona discharge is generated on a surgical handpiece which is used to ignite a plasma arc (19) for surgical operations. The advantages include greater reliability and repeatability of plasma arc (19) ignition. The apparatus comprises a handpiece incorporating an active electrode, a passage for ionizable gas (12), and a corona return electrode (17). The corona return electrode (17) has a terminus on the holder (11) and near the distal end (20) of the holder (11). The corona return electrode (17) is electrically connected to the return path of the electrosurgical generator. A non-uniform electric field is generated between the active electrode (14) and the corona return electrode (17) of sufficient strength so that a corona is formed near the active electrode (14). A separate return electrode (17) may be on the patient (25), or the apparatus may be configured for bipolar electrosurgical operation by carrying the return electrode (17) on the handpiece. A dielectric material separates the active electrode (14) and the corona return electrode (17). There is substantially capacitive coupling between the active electrode (14) and the corona return electrode (17). There is substantially resistive coupling between the active electrode (14) and the return electrode (17).

Abstract: 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.
