A surgical device , comprising: an actuation mechanism; a shaft assembly including an outer elongate shell defining an inner lumen, and the shaft assembly including first and second elongate members extending longitudinally within the inner lumen; and an end effector coupled to a distal end of the shaft assembly; wherein the actuation mechanism is configured to be actuated by a user so as to simultaneously cause a first force to be applied to one of the first and second elongate members , and thereby cause the one of the first and second elongate members to slidably translate proximally and longitudinally within the inner lumen , and cause a second force to be applied to the other of the first and second elongate members , and thereby cause the other of the first and second elongate members to slidably translate distally and longitudinally within the inner lumen , the translation of the first and second elongate members causing articulation of the end effector ; and the surgical device further comprising first and second stabilizing members , the first stabilizing member being attached to the first elongate member via one of welding, crimping, and interference fit, the second stabilizing member being attached to the second elongate member via one of welding, crimping, and interference fit, the actuation of the actuation mechanism being configured to simultaneously longitudinally translate the first stabilizing member , thereby causing the longitudinal translation of the first elongate member , and longitudinally translate the second stabilizing member , thereby causing the longitudinal translation of the second elongate member . an actuation mechanism; a shaft assembly including an outer elongate shell defining an inner lumen, and the shaft assembly including first and second elongate members extending longitudinally within the inner lumen; and an end effector coupled to a distal end of the shaft assembly; wherein the actuation mechanism is configured to be actuated by a user so as to simultaneously cause a first force to be applied to one of the first and second elongate members , and thereby cause the one of the first and second elongate members to slidably translate proximally and longitudinally within the inner lumen , and cause a second force to be applied to the other of the first and second elongate members , and thereby cause the other of the first and second elongate members to slidably translate distally and longitudinally within the inner lumen , the translation of the first and second elongate members causing articulation of the end effector ; and the surgical device further comprising first and second stabilizing members , the first stabilizing member being attached to the first elongate member via one of welding, crimping, and interference fit, the second stabilizing member being attached to the second elongate member via one of welding, crimping, and interference fit, the actuation of the actuation mechanism being configured to simultaneously longitudinally translate the first stabilizing member , thereby causing the longitudinal translation of the first elongate member , and longitudinally translate the second stabilizing member , thereby causing the longitudinal translation of the second elongate member . <EOS>
