Electrode wiping surgical device
First Claim
1. A surgical instrument comprising:
- a handle assembly;
a shaft coupled to a distal end of the handle assembly; and
an end effector coupled to a distal end of the shaft, the end effector comprising;
a first jaw;
a second jaw, wherein the first jaw and the second jaw cooperate to capture tissue therebetween;
the first jaw comprising a first lateral side, a second lateral side, and a third side connecting the first and second lateral sides and facing the second jaw such that the third side is positioned closest to the second jaw as the second jaw closes with the first jaw;
a stapling member configured to fire one or more staples between the first and second jaws; and
an elongated electrode secured to the first jaw, the elongated electrode comprising;
a first long portion that runs longitudinally along the first lateral side of the first jaw from a first proximal point on said first lateral side beginning near a joint connecting the first jaw to the second jaw and extending to a distal end of said first lateral side;
a second portion electrically coupled to the first long portion that runs along a distal end of the third side of the first jaw such that the second jaw closes onto the second portion when the second jaw closes onto the first jaw;
a third long portion electrically coupled to the second portion that runs longitudinally along the second lateral side of the first jaw from a distal end of said second lateral side and extending to a second proximal point on said second lateral side beginning near the joint connecting the first jaw to the second jaw;
a fourth portion running substantially perpendicular to the longitudinal direction of the first long portion and connecting a distal end of the first long portion to the second portion; and
a fifth portion running substantially perpendicular to the longitudinal direction of the third long portion and connecting a distal end of the third long portion to the second portion;
wherein the first long portion and the third long portion are positioned on a first plane distal to the second jaw, and the second portion is positioned on a second plane parallel to the first plane and proximal to the second jaw; and
wherein the elongated electrode is configured to transmit electrosurgical energy throughout the entirety of the first long portion, the second portion, the third long portion, the fourth portion and the fifth portion, to coagulate tissue upon wiping the end effector against the tissue.

Abstract
Aspects of the present disclosure include a surgical device comprising electrodes on the sides of an end of an effector to aide in sealing during various surgical procedures, such as a liver resection. During a sealing procedure, the surgeon may wipe the surgical site with the end effector, causing the electrodes to touch the fractured area. Electrosurgical energy may be applied to the electrodes during the wiping, causing coagulation of smaller vessels, such as tiny blood vessels and bile ducts in the parenchyma of the liver. In some cases, due to the nature of some smaller vessels, electrosurgical energy should be delicately applied to cause sealing but to avoid overly damaging the remaining tissue. In some embodiments, the thin design of the electrodes allows for an appropriate amount of electrosurgical energy to be applied to the fractured area.
