Vessel sealing instrument with electrical cutting mechanism
First Claim
1. An end effector assembly for use with an instrument for sealing, coagulating and/or cutting vessels and/or tissue, the end effector assembly comprising:
- a pair of opposing first and second jaw members at least one of which is movable relative to the other from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween;
each jaw member including an electrically conductive tissue sealing surface extending along a length thereof, each tissue sealing surface adapted to connect to a source of electrosurgical energy such that the tissue sealing surfaces are capable of conducting electrosurgical energy through tissue grasped therebetween to effect a seal;
an insulative support element configured to support each electrically conductive tissue sealing surface;
a first electrically conductive cutting element disposed within the insulative support element of the first jaw member;
a second electrically conductive cutting element disposed within the insulative support element of the second jaw member, the second electrically conductive cutting element generally opposing the first electrically conductive cutting element; and
at least one channel defined within at least one of the insulative support elements, the at least one channel configured to transport fluid adjacent to the electrically conductive cutting element.

Abstract
An end effector assembly for use with an instrument for sealing vessels and cutting vessels includes a pair of opposing first and second jaw members which are movable relative to one another from a first spaced apart position to a second position for grasping tissue therebetween. Each jaw member includes an electrically conductive tissue contacting surface connected to an electrosurgical energy source. At least one of the jaw members includes an electrically conductive cutting element disposed within an insulator defined in the jaw member. At least one channel is included in the insulator which is configured to deliver fluid between the jaw members.
