SURGICAL INSTRUMENT FOR TRANSMITTING ENERGY TO TISSUE COMPRISING NON-CONDUCTIVE GRASPING PORTIONS
First Claim
1. A surgical instrument for supplying energy to tissue, comprising:
- a handle, comprising;
a trigger; and
an electrical input;
a shaft extending from said handle, wherein said shaft comprises a conductor, and wherein said trigger is selectively actuatable to electrically couple said electrical input and said conductor; and
an end effector, comprising;
a first jaw member;
a second jaw member, wherein at least one of said first jaw member and said second jaw member is movable relative to the other of said first jaw member and said second jaw member to clamp tissue intermediate said first jaw member and said second jaw member;
an electrode electrically coupled with said conductor, wherein said electrode is configured to generate heat when electrical energy is supplied to said electrode; and
a tissue-grasping portion comprising a plurality of teeth, wherein said tissue-grasping portion is comprised of an electrically non-conductive material.

Abstract
A surgical instrument for supplying energy to tissue can comprise an end effector comprising a first jaw member and a second jaw member, wherein at least one of the first jaw member and the second jaw member is movable relative to the other of the first jaw member and the second jaw member to clamp tissue intermediate the first jaw member and the second jaw member. The instrument can further comprise an electrode configured to generate heat when electrical energy is supplied to the electrode, and, in addition, a tissue-grasping portion comprising a plurality of teeth, wherein the tissue-grasping portion is comprised of an electrically non-conductive material.
