The reported event could be confirmed, since the product was returned for evaluation and matches the alleged failure.The device inspection revealed the following: visual examination of the received product shows discoloration on many spots which looks like residue from often use and improper cleaning and reprocessing of the item.Furthermore, there are symmetrical dents which look like blows with a hard object such as another instrument.The article has at and around the locking mechanism for the guiding block section many dents, scratches and deformation, including in and around the hexagonal recess.Especially, where the guiding block is inserted, the part shows deformation due to strong forces e.G.Fallen to the ground.The back holding mechanism from the purple adjustment, at the opposite of the purple handle, got ripped off.The torn-off retaining head of the threaded spindle shows very strong deformations which can be attributed to heavy use.The green, purple and white handle, including the hexagonal recess, show discoloration, scratches, dents and deformation due to heavy use.Functional examination of the received product shows that the green and white adjustment mechanism and the locking mechanism for the guiding block are in functional condition.The purple adjustment mechanism can still be moved/rotated but is no longer functional due to the broken part.The current instrument instructions for use state: "¿ inspect the instrument case and instruments for damage when received and after each use and cleaning.Incompletely cleaned instruments should be re-cleaned, and those that need repair set aside for repair service or return to wright.¿ for devices with hinged/mated surfaces or moving components, a biocompatible, surgical-grade lubricant intended for heat sterilized medical instruments (miltex® spray lubrication or equivalent) should be used per the manufacturer¿s guidelines.Apply spray lubricant to the moving components and/or hinged/mated components where appropriate prior to the sterilization process." a review of the device history for the reported lot did not indicate any abnormalities.No corrective actions are required at this time.A review of the labeling did not indicate any abnormalities.No indications of material, manufacturing or design related problems were found during the investigation.Based on investigation, the root cause was attributed to a use related issue.If more information is provided, the case will be reassessed.
