Abstract
A bipolar forceps is provided and includes a housing having a shaft that extends therefrom which defines a longitudinal axis therethrough. The housing including a drive assembly disposed therein and is operable to reciprocate an actuation tube within the shaft. The bipolar forceps includes an end effector assembly operatively connected to a distal end of the shaft and has a pair of first and second jaw members. The first and second jaw members are pivotable about a living hinge and are adapted to connect to an electrosurgical energy source. Each of the jaw members includes a cam slot defined at a proximal end thereof. One or more of the jaw members is operatively connected to a distal end the actuation tube via a cam pin such that distal reciprocation of the actuation tube cams each of the jaw members towards one another about the respective living hinge to grasp tissue.
