Event or Problem Description
It was reported that during a thr procedure, after installing the reflection xlpe 58mm-60mm liner during the surgery, it was found that the liner could not be locked with the outer cup.After trying for 20 minutes, another liner of the same size was opened, and finally the surgery was completed successfully.The event resulted in a total delay of nearly 30 minutes, which increased the risk of bleeding in surgery, nevertheless, no injury to the patient was reported.
Additional Manufacturer Narrative
The associated device, used in treatment, was returned and evaluated.A visual inspection of the returned device could not confirm the stated failure mode.The device has signs of damage from attempted use.The device was manufactured in 2019.A dimensional inspection was attempted but the device was too damaged from the attempted insertion to obtain accurate measurements.A review of complaint history did not reveal additional complaints for the listed batch.A review of the manufacturing records did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.At this time, we do not have reason to suspect that the product failed to meet any product specifications at the time of manufacture.The potential probable cause for this event is likely a procedural error.Based on this investigation, the need for corrective action is not indicated.Should additional information be received, the complaint will be reopened.No further investigation is warranted for this complaint; however, we will continue to monitor for future complaints and investigate as necessary.
