Abstract:
1. A surgical instrument, comprising: an end effector assembly including a pair of jaw members pivotably coupled to one another, at least one of the jaw members moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween; a drive bar defining a longitudinal axis, the drive bar longitudinally translatable between a distal position and a proximal position for moving the jaw members between the spaced-apart position and the approximated position; and a latch mechanism including: wherein, movement of the lever between the initial position and the actuated position effects movement of the stop member within the substantially longitudinal segment of the track in the axial direction, wherein, when the at least one stop member is disposed within the substantially longitudinal segment, movement of the lever from the actuated position to the over-actuated position effects movement of the stop member in both the axial direction and the radial direction from the substantially longitudinal segment to the substantially radial segment to lock the lever in the actuated position, and wherein, when the stop member is disposed within the substantially radial segment, movement of the lever from the actuated position to the over-actuated position effects movement of the stop member in both the axial direction and the radial direction from the substantially radial segment to the substantially longitudinal segment to unlock the lever from the actuated position.
