First Claim
1. A surgical device comprising:
- a handle assembly including an actuation shaft and a movable handle, the movable handle being operably associated with the actuation shaft such that movement of the movable handle effects axial movement of the actuation shaft;
a vertical pawl biased upwardly into engagement with the actuation shaft to prevent movement of the actuation shaft; and
a disconnect mechanism movable into and out of engagement with the vertical pawl, the disconnect mechanism moving the vertical pawl away from the actuation shaft when the disconnect mechanism moves into engagement with the vertical pawl;
the disconnect mechanism including a member that moves with the movable handle to automatically move the vertical pawl away from the actuation shaft with movement of the movable handle.

The handle assembly includes a mode selection mechanism configured to alternate the surgical device between a first grasping mode of operation and a second clamping mode of operation. The handle assembly includes a rotation control member and an articulation lever. The rotation control member is configured to facilitate rotation of the elongated member with respect to the handle assembly. The articulation lever is configured to facilitate articulation of the tool assembly about an axis substantially perpendicular to the longitudinal axis of elongated member. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly configured to clamp and staple tissue in the second clamping mode of operation of the device.
