1. A surgical stapling device comprising:
- an actuator including a housing defining a handle assembly;
an adaptor assembly having a proximal portion releasably secured to the actuator and a distal portion; and
a tool assembly supported on the distal portion of the adaptor assembly, the tool assembly including a first jaw and a second jaw, the first jaw being movable in relation to the second jaw from an unclamped position to a clamped position, the first jaw being secured to the second jaw by distal and proximal approximation shafts, wherein in the unclamped position, the distal approximation shaft is secured to a distal portion of the first jaw and a distal portion of the second jaw to secure the distal portion of the first jaw of the tool assembly to the distal portion of second jaw of the tool assembly, and the proximal approximation shaft is secured to a proximal portion of the first jaw and a proximal portion of the second jaw to secure the proximal portion of the first jaw to the proximal portion of the second jaw.

Abstract
A surgical stapling device includes an elongated tool assembly having spaced first and second jaws positioned to receive a body organ. The length of the tool assembly (which may have a curved configuration) is selected to receive and staple and/or transect a body organ in a single actuation of the tool assembly.

14. A tool assembly comprising:
a first jaw and a second jaw, the first jaw being movable in relation to the second jaw from an unclamped position to a clamped position, the first jaw being secured to the second jaw by distal and proximal approximation shafts, the distal and proximal approximation shafts being configured to effect parallel closure of the first and second jaws of the tool assembly, wherein in the unclamped position, the distal approximation shaft is secured to a distal portion of the first jaw and a distal portion of the second jaw to secure the distal portion of the first jaw of the tool assembly to the distal portion of second jaw of the tool assembly, and the proximal approximation shaft is secured to a proximal portion of the first jaw and a proximal portion of the second jaw to secure the proximal portion of the first jaw to the proximal end of the second jaw. - View Dependent Claims (15, 16, 17, 18, 19, 20)
