PROBLEM TO BE SOLVED: To provide an electrosurgical instrument locating and spacing stop members along jaw members so as to control a spacing between sealing electrodes when the jaw members are in their closed position.SOLUTION: An end effector for an electrosurgical instrument includes a pair of opposing first and second jaw members 2, 3, the two jaw members being movable between an open position, in which the two jaw members are disposed in a spaced relation relative to one another, and a closed position, in which sealing surfaces of the jaw members cooperate to grasp tissue therebetween. A first sealing electrode 9 is located on the first jaw member 2, while a second sealing electrode 10 is located on the second jaw member 3. One or both of the sealing surfaces are provided with electrically conductive stop members 12, the one or more stop members maintaining a predetermined spacing between the first and second sealing electrodes when the jaw members are in their closed position. One or more insulating members are present to prevent the conductive stop members from causing an electrical short between the first and second sealing electrodes when the jaw members are in their closed position.SELECTED DRAWING: Figure 4 |
