Abstract
An endoscopic forceps for treating tissue includes a handle assembly having a elongated shaft extending therefrom that is movable relative to the handle assembly by an actuator. The forceps also includes an end effector assembly with first and second jaw members that are movable about a pivot for clamping tissue. Each of the jaw members include: an insulative housing having an electrically conductive, inwardly facing tissue contacting surface and a flange with a camming surface. The flange includes a spring-like tail that mounts at least partially within the distal end of the elongated shaft to bias the jaw members in an open configuration. A proximal portion of the spring-like tail is biased radially outward within the distal end of the elongated shaft. The actuator is movable to actuate the elongated shaft to cam the flanges to pivot the jaw members to clamp tissue.
