摘要：
Various surgical devices are provided having mechanisms for preventing premature actuation of a cutting mechanism. These devices generally include a handle having one or more actuators and an effector disposed at a distal end of the device and configured to grasp tissue. When the end effector is in an open position, a firing actuator can be positioned so that it cannot be actuated by a user. For example, the firing actuator can be obstructed by a shield or arm when the end effector is in the open position. In other embodiments, the firing actuator can be hidden in a recess formed in the closure actuator until the end effector is moved to the closed position. When the end effector is in the closed position, the firing actuator can be engaged to advance a cutting mechanism, thereby cutting the tissue grasped by the end effector.
