摘要：
A bipolar forceps is provided. The bipolar forceps includes a housing having a shaft including an electrically conductive distal end. A drive assembly is operable to reciprocate an actuation tube within the shaft. A portion of the actuation tube is electrically conductive. An end effector assembly operatively connects to the shaft and includes a pair of first and second jaw members biased in an open configuration. The first and second jaw members are pivotable about a living hinge. Distal reciprocation of the actuation tube causes each of the jaw members towards one another about the living hinge. One of the jaw members is in electrical communication with the distal end of the shaft and the other jaw member is in selective electrical communication with a distal end of the actuation tube such that when the jaw members are in a closed configuration a closed loop electrical circuit is formed.
