A bipolar forceps including a first electrode, a second electrode, and a conductor operably connected to an electrical source, wherein the conductor can be selectively placed in electrical communication with the first electrode when the first electrode is moved between open and closed positions. The conductor can include a contact end which is not in contact with the first electrode when the first electrode is in its open position. In such an open position, the first electrode may not be in electrical communication with the electrical source and, as a result, current may not flow through the first electrode. The first electrode can be moved into its closed position such that the first electrode is in contact with the contact end of the wire. In such a closed position, the first electrode may be in electrical communication with the electrical source allowing current to flow through the first electrode.
