Abstract
An electrosurgical forceps includes a handle and a shaft extending from the handle. The handle is selectively movable to actuate a pair of first and second opposable jaw members pivotably connected to each other at a distal end of the shaft. The jaw members are moveable from an open position to a closed position and are each adapted to connect to an electrosurgical energy source. A first linkage is disposed at least partially within the shaft and is operably coupled between the first jaw member and a second linkage disposed proximal to the first linkage. Selective movement of the handle rotates the second linkage in a first direction, thereby rotating the first linkage in an opposite second direction to move the jaw members between the open and closed positions. In some embodiments, the jaw members are configured in a releasably locked configuration when in the closed position.
