1. A method for performing an electrosurgical procedure using an electrosurgical instrument, the method comprising:
articulating an end effector of the electrosurgical instrument relative to a shaft of the electrosurgical instrument, wherein the end effector is articulated toward a target tissue;
causing the end effector to transition to a closed configuration, wherein the target tissue is grasped by jaws of the end effector in the closed configuration;
reversibly moving an electrode by the target tissue relative to the jaws of the end effector; and
performing an energy treatment cycle to coagulate and cut the target tissue, wherein the energy treatment cycle comprises:
executing a tissue-feathering segment by applying a bipolar energy to the target tissue;
executing a tissue-warming segment following the tissue-feathering segment by continuing to apply the bipolar energy while additionally applying a monopolar energy to the target tissue, thereby applying an energy blend of the bipolar energy and the monopolar energy to the target tissue, wherein the monopolar energy is applied to the target tissue through the electrode;
executing a tissue-sealing segment following the tissue-warming segment by continuing to apply the energy blend to the target tissue while increasing a monopolar power level of a monopolar generator and decreasing a bipolar power level of a bipolar generator; and
executing a tissue-cutting segment following the tissue-sealing segment by discontinuing the bipolar energy but continuing to apply the monopolar energy to the target tissue.
