Event or Problem Description
It was reported that during a urological procedure, a tx30b was opened to complete specimen transection during an urology case overnight.The first blue was fired and then a white 30v reload was asked for.The surgeon asked for additional reloads and staplers to be opened and attempted one firing on the specimen before realizing that the 30 vascular reload was not compatible with the regular tx handle.It was noted upon picking up the product that two of the white vascular loads were missing the bottom plastic piece that keeps the retaining pin in place.It was thrown out intra-operatively after the nurses tried to remove the unfired reloads from the stapler.No consequence to the patient.The specimen's malformed staple line was oversewed using suture.
