Occupation: non-healthcare professional.Investigation evaluation: our laboratory evaluation of the product said to be involved determined that the device would open, but not close upon handle manipulation.The device was returned with a green and brown substance dried on the cups and sheath.The cups would not open when tested, so the green and brown substance was then washed off the cups.The device was then tested and the cups opened but would not close when the handle was manipulated.The device was placed down an olympus scope (2.8 mm channel) with the endoscope placed in a curved position.When the handle was manipulated, the forceps cups would open, but they would not close.The device was sent to the supplier for further evaluation.The supplier provided the following evaluation: one (1) device from the reported event was returned in a zip type bag with proof of decontamination.The returned device was visually evaluated.No defects in the handle, catheter, or cups¿ assembly were detected.The returned device was functionally evaluated.During testing, with the device coiled in three (3), eight (8) inch loops, it was confirmed that the device did not operate properly when the handle was manipulated.The device opened, but did not close as intended.The reported defect for ¿would not open¿ was not confirmed.However, the device would not close.The returned device was disassembled to evaluate the solder connection.Upon further investigation and disassembly of the device tip, it was noted that the device¿s solder connection was not intact.Closer observation revealed that the operator had incorrectly positioned the link wire and control wire ends.The root cause of the failure was operator error.The device history records were reviewed and found to be manufactured in may 2018.Relevant defects were noted in the manufacturing and/or final quality control checklist records.The device history record for the lot number said to be involved was reviewed.A discrepancy or anomaly was not observed with the product that was released for distribution.Investigation conclusion: the supplier provided the following: the originally reported issue of "forceps would not open" was confirmed.The root cause was operator error.The operators involved will be retrained on the soldering process; specifically correct soldering per specifications.Prior to distribution, all captura serrated large forcep- spike are subjected to a visual inspection and functional test to ensure proper workability.A review of the device history record confirmed that the lot said to be involved met all manufacturing requirements prior to shipment.Corrective action: a review of the complaint history was conducted.The likelihood of occurrence is considered rare.Corrective action is not warranted at this time based on the quality engineering risk assessment.Quality assurance will continue to monitor for complaint trends and reassess the risk assessment results as post market feedback continues to become available.
