Example 4
The surgical instrument of any one or more of Examples 1 through 3, wherein the shaft assembly further includes a second elongate member extending from the proximal shaft portion and toward the end effector, wherein the second elongate member is operatively connected to at least one of the distal shaft portion or the end effector and configured to be selectively moved, wherein the articulation section further includes a second lumen radially offset at a predetermined distance from each of the proximal and distal axes at each of the first and second intersection points when the end effector is in the straight configuration, wherein the second lumen movably supports the second elongate member therethrough such that the radial spacing of the second elongate member is maintained at the predetermined distance at each of the first and second intersection points when the end effector is deflected to the deflected configuration.
Example 5
The surgical instrument of Example 4, wherein the second elongate member intersects each of the first and second articulation axes for deflection of the end effector.
