  • Patent number: 7857186
    Abstract: A surgical stapling instrument including first and second jaw members which can be pivotably connected to each other and secured in position relative to each other by a latch. The first and second jaw members can include first and second locking members which can allow the first and second jaw members to be rotated relative to one another but prevent, or at least inhibit, the first and second jaw members from being separated from one another. Such embodiments may be particularly useful in circumstances when the latch is in a partially-closed position and the first and second jaw members are being manipulated to position tissue therebetween. The first and second jaw members can be sufficiently connected together in order to prevent, or at least reduce the possibility of, the first and second jaw members from becoming detached from one another and exposing a cutting member.
