Abstract
A surgical device is disclosed which includes a handle portion, a central body portion and a SULU. The SULU includes a proximal body portion, an intermediate pivot member and a tool assembly. The intermediate pivot member is pivotally secured to the proximal body portion about a first pivot axis and the tool assembly is pivotally secured to the intermediate pivot member about a second pivot axis which is orthogonal to the first pivot axis. The SULU includes a plurality of articulation links which are operably connected to the tool assembly by non-rigid links. The articulation links are adapted to releasably engage articulation links positioned in the central body portion. The body portion articulation links are connected to an articulation actuator which is supported for omni-directional movement to effect articulation of the tool assembly about the first and second axes. The handle portion includes a spindle and barrel assembly drive mechanism for advancing and retracting a drive member positioned in the tool assembly. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly.

16. A surgical device comprising:
a handle portion including a body defining a stationary handle, a movable trigger, a spindle supported within the body and a barrel assembly slidably positioned about the spindle, the spindle defining a first guide track for slidably receiving a first rack, the first rack being operably connected to a drive member of the surgical device, the barrel assembly including a first pawl which is selectively movable from a first position engaging the first rack to a second position disengaged from the first rack, the movable trigger being operably associated with the barrel assembly such that movement of the movable trigger effects axial movement of the barrel assembly in relation to the spindle, wherein when the first pawl is in its first position, movement of the barrel assembly in a first axial direction effects corresponding axial movement of the first rack to effect movement of the drive member of the surgical device. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A surgical device comprising:
-
a handle portion including a movable trigger, and a first guide track for slidably receiving a first rack, the first rack being operably connected to a drive member of the surgical device, the handle portion further including a first pawl, the first pawl being selectively movable from a first position in relation to the first rack to a second position in relation to the first rack, the handle portion further including a movable shift assembly having a member that moves the first pawl from the first position to the second position, the movable trigger being operably associated with the first pawl, wherein when the first pawl is in its first position, the first pawl effects corresponding axial movement of the first rack to effect movement of the drive member of the surgical device. - View Dependent Claims (25, 26, 27, 28, 29, 30)
