A product investigation was completed: one graphic case (part 690.413, lot unknown) and its associated inserts and trays were received for investigation.The graphic case is severely worn with wear and fading evident on most surfaces as well as the trays/inserts.The nylon coating on various inserts has worn off in a few locations.One screw is missing from the lid of the internal screw caddy (part 690_413_40).The lid of the caddy does not properly latch.The root cause for the lost screw is unknown, but due to the condition of the cause, wear from use and sterilization is likely a contributing factor.Upon inspection, it was found that the device was missing subcomponent part 690_413_43.This causes the lid of the screw module to not properly latch, thereby allowing the screws to unintentionally come out.The relevant drawing for the device(s) was reviewed.No drawing issues or discrepancies were noted.The design was determined to be suitable for the intended use when employed and maintained as recommended.A review of the device history records was unable to be performed since the lot number is unknown.No manufacturing or design issues were noted during the investigation.The design is determined to be adequate for its intended use when used and maintained as recommended.Device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
