Investigation evaluation: our laboratory evaluation of the product said to be involved confirmed the report.During evaluation of the device the handle was manipulated and the forceps cups would open, but they would not close.The device was then advanced down an olympus 2.8 mm channel endoscope.The endoscope was placed in a curved position.When the handle was manipulated, the forceps cups would open slightly, and then close.The endoscope was then readjusted and placed in a straight position.When the handle was manipulated, the forceps cups would open, but they would not close.Several attempts were made to close the forceps cups before manually closing the cups by hand.The device was sent to the supplier for further evaluation.The supplier provided the following evaluation: one device from the reported event was returned in a zip type bag with proof of decontamination.Evaluation of the device determined that the returned device was tested for "would not close".During functional testing, with the device coiled in three (3), approximately eight (8) inch loops, it was confirmed that the device would not operate properly when the handle was manipulated.The device does not open or close.Upon further investigation and disassembly of the device tip, it was noted that the device has a broken solder joint.The reported defect was confirmed.Failure was due to a broken solder joint.The device history record for the packaging work order was reviewed.The packaging work order consisted of one assembly order manufactured in november 2016.No 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 "forceps will not close" issue experienced by the customer was confirmed.During functional testing, the device would not operate properly.It was determined that the device has a broken solder joint.They are currently working on improvements to create a more robust soldering process to prevent solder joints from breaking.In addition, a corrective action has been initiated to reduce occurrences of cups open/close difficulties for disposable forceps.The product said to be involved is included in the scope of the corrective actions.The instruction for use state the following in regards to product inspection: "beginning at handle and moving toward the cups, uncoil the forceps making sure not to stretch the cable.Open and close the cups to verify smooth handle operation and appropriate cup action.Note: exercising the handle while the forceps is coiled may result in damage to the performance characteristics of the forceps." prior to distribution, all captura serrated forceps with 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.A corrective action has been initiated in an effort to reduce occurrences of this nature.This product was included in the scope of this corrective action.Quality assurance will continue to monitor for complaint trends and reassess the risk assessment results as post market feedback continues to become available.
