Tissue Fusion Jaw Angle Improvement
First Claim
1. A bipolar forceps, comprising:
- an end effector assembly having opposing first and second jaw members having proximal and distal ends and selectively moveable relative to one another from a first spaced apart position to a second position wherein the jaw members cooperate to grasp tissue therebetween, each of the jaw members including an electrode having an electrically conductive tissue sealing surface adapted to connect to an electrical energy source such that the electrically conductive tissue sealing surfaces are capable of conducting energy to tissue disposed therebetween,wherein at least one of the electrodes is pivotably connected to a respective jaw member about a pivot disposed at a distal end thereof to promote parallel closure of the electrically conductive tissue sealing surfaces against tissue disposed between the jaw members.

Abstract
A bipolar forceps for sealing tissue includes an end effector assembly having opposing first and second jaw members having a proximal end and a distal end. The jaw members are moveable relative to one another from a first spaced apart position to a second position in which the jaw members cooperate to grasp tissue. Each of the jaw members includes an electrode having an electrically conductive tissue sealing surface. An electrical energy source may be connected to the tissue sealing surfaces so that the sealing surfaces can conduct energy to tissue. Each electrode may be pivotably connected on a distal end to the respective jaw member to promote parallel closure of the sealing surfaces against tissue between the jaw members. Each electrode may be connected to its respective jaw member on a proximal end via a resilient member to bias the electrode against tissue disposed between the jaw members.
