Event or Problem Description
It was reported that when using a sterilized drill through a sleeve, the sleeve and drill got stuck.The surgeon opened the spare drill tip and used it with another sleeve, but the same event occurred in other hole.After that, the surgery was completed using a 3mm k wire as a substitute and a tap.
Additional Manufacturer Narrative
The reported event could be confirmed, since the device was returned for evaluation and matches the reported failure mode.The device inspection revealed the following: the drill and the drill sleeve were found to be stuck with each other.The drill portion, outside the sleeve, showed heavy circular marks caused due the drill making contact with the sleeve edge under intense usage.There was no clearance/play between the drill and the sleeve.The drill sleeve was cut to further investigate and the cut section revealed that the drill is welded inside the sleeve, most likely due to excessive misaligned rotation during the surgery, causing friction.Slightly abraded inner surface of the sleeve, due to frequent usage, was also observed which may have been another reason for excessive friction.The batch record could not be reviewed because the lot number was not communicated and could not be identified from the returned product as the product information was scratched.A review of the labeling did not indicate any abnormalities.Based on the investigation, the root cause of the issue is user related.Drill getting stuck (welded) inside the sleeve is a direct result of excessive friction between the drill and the sleeve due to a potential misalignment during use causing excessive friction to an extent of devices getting welded.If any further information is provided, the complaint report will be updated.
