1. A surgical device, comprising:

  • an end effector having first and second jaws configured to move relative to one another between an open position in which the first and second jaws are spaced a distance apart from one another and a closed position in which the first and second jaws are configured to grasp tissue therebetween; and

    a handle portion havinga first actuator operatively associated with the first and second jaws and movable between a first position and a second position, movement of the first actuator from the first position to the second position being effective to move the first and second jaws from the open position to the closed position, anda second actuator configured to advance a cutting element distally along the first and second jaws to cut the tissue grasped therebetween, the second actuator having an opening configured to receive a user'"'"'s finger; and

    at least one blocking member configured to move relative to the second actuator, movement of the first actuator from the first position to the second position being effective to move the at least one blocking member from an obstruction position in which the at least one blocking member obstructs the opening of the second actuator so that a user is hindered from actuating the second actuator, to a firing position in which the at least one blocking member is displaced away from the opening of the second actuator.
