A surgical device includes a handle assembly, an elongated member, and a tool assembly. The handle assembly includes a mode selection mechanism configured to alternate the surgical device between a grasping mode of operation and a clamping mode of operation. The tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly. The tool assembly is configured to grasp and release tissue in the grasping mode of operation and configured to clamp and staple tissue in the clamping mode of operation. The mode selection mechanism includes a switch and a pawl. When a moveable handle of the handle assembly is compressed with the switch held in a depressed position, the device is in the grasping mode of operation. When the moveable handle is compressed with the switch in a neutral position, the device is in the clamping mode of operation.
1. A surgical device comprising: a handle assembly including an actuation shaft, a stationary handle, and a movable handle, the movable handle being moveable from a non-compressed position to a compressed position and being operably associated with the actuation shaft such that movement of the movab
1. A surgical device comprising: a handle assembly including an actuation shaft, a stationary handle, and a movable handle, the movable handle being moveable from a non-compressed position to a compressed position and being operably associated with the actuation shaft such that movement of the movable handle effects axial movement of the actuation shaft between an extended position and a retracted position;an elongated member extending distally from the handle assembly, the elongated member defining a longitudinal axis;a tool assembly supported on a distal end of the elongated member, the tool assembly including a cartridge assembly having a plurality of staples supported therein and an anvil assembly, the anvil assembly and the cartridge assembly being movable in relation to each other between open and closed positions;an actuation assembly including an actuation pawl pivotally coupled to the moveable handle and operatively associated with the actuation shaft to advance the actuation shaft upon movement of the moveable handle, the actuation assembly further including an actuation arm, an actuation button movable between a centered position and a non-centered position, and a grasping pawl coupled to an end of the actuation arm, the actuation arm moveable between an extended position when the actuation button is in the centered position and a retracted position when the actuation button is in the off-centered position, wherein in the extended position the grasping pawl is positioned to engage the actuation shaft in a grasping mode of operation and in the retracted position the grasping pawl is out of engagement with the actuation shaft in a clamping mode of operation; anda mode selection mechanism including a lock pawl and a lock pawl biasing member positioned to urge the lock pawl into engagement with a distal surface of the actuation shaft to prevent advancement of the actuation shaft from the retracted position, the mode selection mechanism further including a switch pawl, a switch, and a switch pawl biasing member that urges the switch pawl into engagement with the actuation shaft, the switch configured to cam the switch pawl against the switch pawl biasing member and out of engagement with the actuation shaft to permit operation of the device in the grasping mode of operation. 2. The device of claim 1, wherein compression of the moveable handle towards the stationary handle effects advancement of the actuation shaft and when in the grasping mode of operation movement of the movable handle away from the stationary handle effects retraction of the actuation shaft. 3. The device of claim 1, wherein the switch is biased in a neutral position. 4. The device of claim 1, wherein the switch pawl prevents retraction of the actuation shaft when the switch pawl is engaged with the actuation shaft. 5. The device of claim 1, wherein the switch includes a detent operatively associated with the switch pawl and configured to cam the switch pawl against the switch pawl biasing member and out of engagement with the actuation shaft. 6. The device of claim 1, wherein the mode selection mechanism includes a disconnect link operatively associated with the moveable handle and the lock pawl, the disconnect link configured to cam the lock pawl against the lock pawl biasing member and out of engagement with the actuation shaft. 7. The device of claim 6, wherein the disconnect link has a distal recess and the lock pawl has a camming protrusion, the camming protrusion being disposed in the distal recess when the device is in the grasping mode of operation. 8. The device of claim 7, wherein the disconnect link has a proximal recess, the lock pawl engaging the distal surface of the actuation shaft when the camming protrusion is disposed in the proximal recess.
