According to the reporter, during a laparoscopic mini gastric bypass, on stomach transection, the handle was able to fire a load initially without incident.While trying to perform the second firing, the knife blade and staples did not advance.The green button was activated, the ring handle kicked out, but then upon pulling the ring handle it would squeeze as per usual, but there was no activity within the staple load.The teeth did not engage the pushing mechanism.This was evident again upon testing post-operatively.No malfunction was apparent during the first successful firing of the stapler.A new product was opened and used to complete the case.There was no patient injury.
