    Abstract: A surgical instrument is provided and includes a housing having a shaft. An end effector assembly is operatively connected to a distal end of the shaft and has a pair of first and second jaw members that are movable relative to one another. A drive assembly operably couples to a handle assembly associated with the housing and is configured to impart movement of a respective jaw member when the handle assembly is actuated. A spring component operably associated with each of the jaw members is configured to provide a sealing force at the jaw members.

    Abstract: A jaw member for a surgical instrument includes a jaw housing and a first electrically conductive material deposited atop the jaw housing. An electrical wire is operably associated with the jaw housing and includes an exposed, electrically conductive tip. The exposed, electrically conductive tip is disposed atop the first electrically conductive material. A second electrically conductive material is deposited atop the exposed, electrically conductive tip to secure the exposed, electrically conductive tip in electrical contact with the first electrically conductive material.

    Abstract: An electrosurgical instrument end effector has first and second jaw members each including an electrically conductive tissue-contacting surface. The first and second jaw members are configured to grasp and electrosurgically treat tissue between the tissue-contacting surfaces. A thermal cutting element includes a body portion extending along the tissue-contacting surface of the second jaw member and a distal probe portion extending distally therefrom. The distal probe portion extends distally beyond a distal-most extent of the second jaw member, has a free end distally-spaced from this distal-most extent, and is exposed about the entire outer periphery thereof between the distal-most extent the free end. The body portion of the thermal cutting element is energizable for thermally treating tissue grasped between the tissue-contacting surfaces, while the distal probe portion of the thermal cutting element is energizable for thermally treating tissue positioned distally of the first and second jaw members.

    Abstract: An enhanced haptic feedback system for medical diagnostics includes a laparoscope configured to be inserted into a body cavity to view tissue and obtain an image of the viewed tissue. An imaging device is configured to acquire physiological data about tissue, process the acquired physiological data, and output the processed data to a graphical user haptic interface (GUHI) capable of generating tangible sensations utilizing one or more haptic interfaces. The GUHI is configured to combine the image received from the laparoscope and the processed physiological data received from the imaging device to provide tangible sensations on both a front screen of the GUHI and a rear screen of the GUHI allowing a surgeon the sensation of feeling for abnormal tissue conditions between the surgeon's hands.

    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.
