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.
