Abstract:
1. A surgical stapling device, comprising; a first jaw; a second jaw having an open position and a closed position with respect to the first jaw; an actuating bar arranged in the first jaw and including a first set of ratchet teeth; a ratchet piston configured to oscillatingly displace the actuating bar along a longitudinal direction of the first jaw; a housing; having at least one staple and at least one staple driving slot, situated in the first jaw; and a carriage, including at least one staple-driving wedge, selectively engageable with the first set of ratchet teeth of the actuating bar to translate the carriage in a distal direction through the housing from a proximal terminal position to a distal terminal position, a distance between the distal terminal position and the proximal terminal position greater than a stroke length of the oscillating displacement of the ratchet bar; wherein the staple driving wedge is adapted to drive the staple through the staple driving slot against the second jaw during distal movement of the carriage through the housing.
