    Abstract: An electrosurgical forceps includes a shaft that extends from a housing of the electrosurgical forceps. An end effector assembly is operably coupled to a distal end of the shaft and includes a pair of first and second jaw members. Each jaw member has a jaw housing and an electrosurgical seal plate. The first jaw member is movable relative to the second jaw member from an open configuration to a clamping configuration. The first jaw member includes an elongated channel defined in its respective jaw housing and extends along a length thereof. A drive assembly operably couples to the first jaw member via a drive rod that is engageable with the elongated channel to move the first jaw member from the open configuration to the clamping configuration and to provide a closure force between the jaw members when the jaw members are in the clamping configuration.

    Abstract: A surgical instrument includes a housing, a shaft extending from the housing, an end effector assembly extending from the shaft and configured to rotate and/or articulate relative to the housing, a motor disposed within the housing and operably coupled to the end effector assembly to rotate and/or articulate of the end effector assembly relative to the housing, and a sensing assembly configured to sense movement of the housing relative to a reference position and to drive the motor to rotate and/or articulate of the end effector assembly relative to the housing based upon the sensed movement. The sensing assembly is configured to operate in each of a standard mode, wherein movement of the housing effects rotation and/or articulation of the end effector assembly in a similar direction, and a reversed mode, wherein movement of the housing effects rotation and/or articulation of the end effector assembly in an opposite direction.

    Abstract: An electrosurgical instrument including an end effector assembly having first and second jaw members and at least first and second thermal cutting elements. Each of the first and second jaw members includes an electrically conductive tissue contacting surface. At least one of the first or second jaw members is movable relative to the other from a spaced apart position to an approximated position to grasp tissue between the tissue contacting surfaces. The first and second jaw members are adapted to connect to a source of energy for electrosurgically treating tissue grasped between the tissue contacting surfaces. Each of the first and second thermal cutting elements is disposed on or within one of the first or second jaw members and adapted to connect to a source of energy for thermally treating tissue.

    Abstract: A surgical forceps includes a housing having a movable handle coupled thereto and movable between an initial position and a compressed position. A drive bar is operably coupled to the movable handle such that movement of the movable handle between the initial and compressed positions effects longitudinal translation of the drive bar. The drive bar further includes a coupling member disposed at a distal end thereof. An end effector assembly includes first and second jaw members movable between spaced-apart and approximated positions. Each jaw member defines a cam slot. A cam pin is slidably disposed within the cam slot of each of the jaw members. The coupling member is configured to releasably engage the cam pin such that movement of the movable handle between the initial position and the compressed position effects movement of the jaw members between the spaced-apart position and the approximated position.
