摘要：
Instruments and methods for providing selective surgical instrument trigger lockout are provided herein. In one embodiment, a surgical instrument can include a distal end effector, a proximal actuator portion, a first trigger, a second trigger, and a lock arm. The lock arm can be configured to move between a first position, in which it interferes with actuation of the first trigger, and a second position, in which it permits actuation of the first trigger. Further, actuation of the second trigger can be effective to move the lock arm from the first position to the second position. Actuation of the first trigger can therefore be prevented if the second trigger is not already actuated. Selective trigger lockout can be useful in a variety of instruments, including, for example, surgical instruments that grasp, seal, and transect tissue.
