Abstract

To provide a surgical stapler that increases reliability of clamped tissue without complex mechanisms.SOLUTION: A surgical stapling system may include a reload shaft. The shaft may include an elongate tubular member, and the tubular member may have a jaw assembly at a distal end thereof and a coupling collar at a proximal end thereof. A shaft assembly may also include an articulation joint coupling the jaw assembly to the distal end. A drive member and an articulation member extend within a tubular body of the shaft from the proximal end to the distal end. A firing member is connected to a distal end of a drive member such that advancement of the drive member advances the firing member to close the jaw assembly and fire staples from a reload part positioned in the jaw assembly. The shaft assembly may further include a lockout mechanism to prevent a firing operation on a previously fired reload part or not fired reload part.SELECTED DRAWING: Figure 1
