Abstract
A surgical instrument comprising an end effector, which comprises a first jaw and a second jaw transitionable between open and closed configurations. The first jaw comprises a first grasping surface that forms a first electrode configured to deliver radio frequency (RF) energy and the second jaw comprises a second grasping surface that forms a second electrode configured to receive the RF energy. Each jaw comprises grasping features that are configured to cooperate with the opposing grasping features. The surgical instrument further includes a tissue adhering portion disposed on an exterior of the end effector. The end effector is attached to the shaft by an articulation joint comprising a multi-axial range of movement.
