Dielectric Jaw Insert For Electrosurgical End Effector
First Claim
1. An end effector assembly for use with an electrosurgical instrument, the end effector assembly comprising:
- a pair of opposing first and second jaw members each having a tissue contacting surface, at least one of the first and second jaw members being monolithic and at least one jaw member moveable relative to the other from a first, open position to a second, closed position for grasping tissue, the at least one monolithic jaw member having a cavity defined therein; and
a jaw insert selectively positionable within the cavity of the at least one monolithic jaw member, at least a portion of the jaw insert including a dielectric material configured to reduce the thermal mass of the at least one monolithic jaw member.

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.
