A surgical instrument includes a first arm, wherein the first arm comprises a first jaw, and wherein the first jaw includes a first electrically conductive member. The surgical instrument further includes a second arm, wherein the second arm comprises a second jaw, wherein the second jaw includes a second electrically conductive member, wherein the first arm is pivotable relative to the second arm between an open configuration and a closed configuration to capture tissue, and wherein the electrically conductive members are configured to cooperate to deliver energy to the tissue. The surgical instrument further includes a cutting beam, an actuator actuatable proximally to translate the cutting beam distally to sever the tissue, a support structure, and a flexible member extending at least partially around the support structure, and configured to couple the actuator to the cutting beam.
