ABSTRACT:
An endoscopic forceps for treating tissue includes a handle assembly having a elongated shaft extending therefrom which is movable relative to the handle assembly by an actuator. The forceps also including an end effector assembly attached to a distal end of the shaft which has first and second jaw members which are movable about a pivot from a first position in spaced relation relative to one another to a second position for clamping tissue. Each of the jaw members include: an insulative outer housing having an electrically conductive, inwardly facing tissue contacting surface and a proximal flange with a camming surface. The proximal flange being provided with a spring-like tail which mounts within the distal end of the elongated shaft to bias the jaw members in an open configuration. The actuator is movable relative to the handle to actuate the elongated shaft to cam the proximal flanges to pivot the jaw members toward the second position to clamp tissue.
