Abstract

An electrosurgical instrument (10) includes a housing (20), a shaft (50) coupled to the housing, and an end effector assembly (100) disposed at a distal end of the shaft. The end-effector assembly (100) includes first and second jaw members (110, 120), at least one of which is movable from a first position wherein the jaw members are disposed in spaced relation relative to one another to at least a second position closer to one another wherein the jaw members cooperate to grasp tissue therebetween. The second jaw member (120) includes an electrically-conductive tissue-engaging surface (129) and a protruding element (122) extending therefrom. The protruding element (122) is configured as an elongated strip extending along a length of the second jaw member. The electrosurgical instrument (10) also includes a vibration coupler (60) and an oscillation mechanism (30) configured to generate mechanical vibration in the vibration coupler (60). The vibration coupler (60) includes a distal end movably coupled to a proximal end of the second jaw member (120).
