摘要：
An apparatus includes a body, an end effector, and outer beam, and an inner beam. The body comprises an actuator. The end effector is in communication with the body and has a first jaw and a second jaw. The outer beam is able to advance within the end effector such that the outer beam closes the second jaw toward the first jaw. The advancement of the outer beam is controlled mainly by the actuator. The inner beam is also able to advance within the end effector such that the inner beam transects tissue. The actuator is operable to control the advancement of the inner beam in at least two stages. The actuator advances the inner beam and the outer beam together in a first state. The actuator advances the inner beam while the outer beam remains stationary in a second stage.
