1. An electrosurgical instrument, comprising:

  • an electrically insulated handle having distal and proximal ends, wherein the proximal end branches to form two arm-like portions and the distal end widens to form an approximately tubular body portion having features sized for receiving at least an index finger and a thumb;

    gas and electrical conduits disposed within the handle for connection to external gas and electrical sources;

    a hollow elongated electrode extending from the distal end of the handle and defining a gas conduit along its length, the elongated electrode operably coupled to the gas and electrical conduits;

    an elongated insulating sheath enclosing the elongated electrode; and

    an actuator mechanism operably coupled to the handle, the elongated electrode, and to the gas and electrical conduits, the actuator mechanism configured to alternate between at least two states;

    wherein a first state prevents electric current and gas from reaching the elongated electrode, and wherein a second state allows electric current and gas to reach and flow through the elongated electrode to generate and ionized plasma gas stream for electrosurgery.
