摘要：
An electrosurgical instrument comprising an end effector is disclosed. The end effector comprises a first jaw and a second jaw. The first jaw comprises a first electrode. The end effector is movable from an open configuration to a closed configuration to grasp tissue. The second jaw comprises a second electrode configured to deliver a first monopolar energy to the tissue, a third electrode, and a conductive circuit selectively transitionable between a connected configuration with the third electrode and a disconnected configuration with the third electrode. In the connected configuration, the third electrode is configured to cooperate with the first electrode to deliver bipolar energy to the tissue. The conductive circuit defines a return path for the bipolar energy. In the disconnected configuration, the first electrode is configured to deliver a second monopolar energy to the tissue.
