Abstract
A surgical instrument comprising a first jaw, a second jaw rotatable relative to said first jaw, and jaw drive system is disclosed. The jaw drive system comprises a drive screw and a closure member threadably engaged with the drive screw configured to close the second jaw. The jaw drive system further comprises an opening link connecting the closure member to the second jaw which acts to open the second jaw when the closure member is driven in an opposite direction. In the event that the second jaw is not opened by the closure link, the jaw drive system further comprises a pull member which is pushed by the closure member to dislodge the second jaw into its open position.
