Patent abstract
A surgical fastening device provides a mechanism for manually retracting the drive shaft, drive beam, and associated components in the event of a jamming or misfiring condition. The device includes a handle housing from which an elongate shaft extends and an end effector at a distal end of the shaft. The end effector has a cartridge jaw and an anvil jaw in a pivoting arrangement. A drive shaft actuates a drive beam, which acts to drive fasteners from the cartridge jaw into tissue. The device include a first retraction mechanism configured to move linearly and proximally to retract the drive beam and drive shaft, and a second retraction mechanism that likewise is able to retract the drive beam and drive shaft.
