Abstract
The present disclosure relates to an end effector assembly for use with an electrosurgical instrument and methods of manufacturing the same. The end effector assembly includes a pair of opposing first and second jaw members and a jaw insert. Each of the opposing jaw members has a tissue contacting surface and one or more of the jaw members are monolithic. Additionally, at least one of the jaw members is moveable relative to the other from a first, open position to a second, closed position for grasping tissue. The monolithic jaw member also has a cavity defined therein. The jaw insert is selectively positionable within the cavity of the monolithic jaw member. The jaw insert includes a tissue contacting surface and a portion of the jaw insert includes a dielectric material configured to reduce the thermal mass of the monolithic jaw member.
