Device evaluation: one non-original carton containing a bag with a used and decontaminated spinal needle as well as six unopened trays for product with the same lot were received for investigation.A dhr review was completed for the product and no issues were found.Immediate visual inspection of the complaint (used) sample revealed that the cannula and a needle hub were not connected.No defects or anomalies were observed on any of the unused samples.No marks along the cannula were observed.It also revealed the hub end of the complaint cannula was damaged.The look of the damaged end was indicative of a cannula which had been bent severely to either side until completely broken from the hub.The cannula was also noticeably bent along its axis, near the center, indicating that it had received undue forces.The hub portion of the needle appeared to be undamaged.The glue cone was still intact within the hub.The glue cone retained a small portion of the needle cannula, thus confirming the complaint for breakage of the needle.Inspection of each fragment using magnification, revealed what appeared to be tool marks near the broken end of the cannula.In addition, the six unopened samples were tested for resistance to breakage and no breakage was observed on any of the samples.All samples passed the breakage test without issue.Furthermore, a straight portion of the used cannula was removed and was tested for breakage in the same manner and used cannula remained intact.No sign of breakage was observed.This testing determined that the cannulas of the used and unused samples of the spinal needle (ne588), successfully met the requirements of the above standard for resistance to breakage.All cannulas functioned as intended.The issue observed by the customer could not be reproduced during this investigation, but the complaint allegation was confirmed due to the evidence of the complaint sample damage.The root cause is noted as unknown.
