摘要：
A bipolar forceps is provided and includes a housing having a shaft that extends therefrom. The housing includes a drive assembly operable to reciprocate an actuation tube within the shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members biased in an open configuration. One or both of the first and second jaw members is pivotable about a living hinge from a first position to a clamping position. One or both of the jaw members includes a cam slot defined at a proximal end thereof. One of the jaw members is operatively connected to a distal end of the actuation tube via a cam pin that operatively engages the cam slot such that proximal reciprocation of the actuation tube cams at least one jaw member towards the other jaw member about the living hinge.
