1. An electrosurgical handpiece comprising:

  • (a) a first main body,(b) a second main body axially aligned with and coupled to the first main body,(c) a squeezable handle connected to the first and second main bodies such that, when the handle is unsqueezed, the first and second main bodies assume a first relaxed position relative to one another, and when the handle is fully squeezed, the first and second main bodies assume a second fully squeezed position relative to one another, and when the handle is partially squeezed, the first and second main bodies assume a third partially squeezed position relative to one another,(d) a first tubular member having a distal end and a second end connected to one of the first and second main bodies,(e) a bipolar electrosurgical electrode comprising active separable distal ends and connecting links connected to the other of the first and second main bodies and extending within the tubular member,characterized in that;

    (f) the active distal ends and their connecting links are configured such that;

    i) when the handle is unsqueezed the active distal ends protrude from the distal end of the first tubular member and are adjacent one another, andii) when the handle is fully squeezed the active distal ends are fully extended outwardly from the first tubular member and separate, andiii) when the handle is relaxed but still partially squeezed, the active distal ends come together in a position to grasp tissue for receiving electrosurgical currents.
