    摘要: A surgical instrument includes an active electrode coupled to a source of electrosurgical energy. The active electrode includes a tissue-contacting surface on an exterior surface of the instrument such that the tissue-contacting surface of the active electrode may intimately engage tissue. A replacement electrode includes a tissue-contacting surface, and is located in an interior cavity of the instrument. A seal is formed between the active electrode and the interior cavity of the instrument such that the tissue-contacting-surface of the replacement electrode is isolated from contamination exposed to the exterior of the instrument. The active electrode is removable from the instrument to expose the tissue-contacting surface of the replacement electrode, and the replacement electrode is connectable to the source of electrosurgical energy when the active electrode is removed.

    摘要: A surgical instrument includes a handle coupled to a source of electrosurgical energy. A pair of opposed jaw members is operatively coupled to a distal end of the handle such that the jaw members selectively move between open and closed positions. A base supported on one of the jaw members includes a mechanical mating feature and an electrically conductive region in electrical communication with the source of electrosurgical energy. A selectively removable seal plate includes a complementarily engaging a mechanical mating feature and an electrically conductive region positioned to contact the electrically conductive region of the base when the mechanical mating features of the base and seal plate are engaged. The complimentarily-engaging mechanical mating features include a pair of spaced protrusions and a pair of spaced recesses open to opposing sides of the base or the seal plate such that the seal plate may be twisted onto the base.
