Abstract: 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.

Abstract: An endoscopic bipolar forceps includes a housing having a shaft affixed thereto the shaft including jaw members at a distal end thereof. The shaft includes a longitudinal axis defined therethrough and the jaw members are adapted to connect to a source of electrosurgical energy such that the jaw members are capable of conducting energy through tissue held therebetween to effect a tissue seal. A movable handle is included that is rotatable about a pivot to force a drive assembly to move the jaw members between the first and second positions. The pivot is located a fixed distance above the longitudinal axis. A cutting assembly is included having at least one blade element disposed within one of the jaw members. The blade element is selectively moveable from a first recessed position within the jaw member to a second extended position for cutting tissue. The cutting assembly also includes a remote actuator which reciprocates a camming element to move the blade element between the first and second positions.

Abstract: An end effector of a forceps includes first and second jaw members movable between spaced-apart and approximated positions for grasping tissue. Each jaw member includes a tissue sealing plate that is selectively energizable. The tissue sealing plates are configured to conduct energy therebetween and though tissue to seal tissue. A knife includes a distal surface and an upper surface. The knife is selectively translatable between a retracted position and an extended position wherein the knife extends between the jaw members. The distal surface is configured for dynamic tissue cutting upon translation of the knife from the retracted to the extended position. The upper surface is configured for static tissue cutting with the knife in the extended position. The knife is selectively energizable and is configured to conduct energy between the knife and one or both of the tissue sealing plates and through tissue to electrically cut tissue.
