A bipolar forceps includes a mechanical forceps including first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another about a pivot. A disposable housing is configured to releasably couple to at least one of the shafts and an electrode assembly is associated with the disposable housing. The electrode assembly includes electrodes releasably coupleable to the jaw members. At least one of the electrodes includes a knife channel configured to receive a knife blade therethrough to cut tissue grasped between the jaw members. A switch is configured to initiate delivery of electrosurgical energy from the source of electrosurgical energy to the electrodes. An actuation mechanism is configured to selectively advance the knife blade through the knife channel to cut tissue.

A method of assembling an electrosurgical instrument includes coupling first and second shafts to each other about a pivot. Each of the shafts has an interior side facing the other shaft and an exterior side opposite the interior side. The method also includes disposing a knife blade at least partially through a passageway defined through the pivot from the exterior side of the first shaft and coupling a knife actuation mechanism to the first shaft from the exterior side of the first shaft. The knife actuation mechanism is configured to move the knife blade through the passageway.
