Manufacturer Narrative
|
The disposable perforator (id 261221) was returned for evaluation.Device history record (dhr) - there is no indication that the production process may have contributed to this complaint.All test results passed procedural specifications.Failure analysis - while the unit was not able to cut the wood, this was determined to be unrelated to the manufacturing process and likely occurred during surgery.The manufacturing lead and machine operators tried to reproduce the rounded cutting edges on a fresh unit and were unsuccessful.The only step in the perforator manufacturing process that could have potentially caused the rounded edges is during deburring, but ¿over deburred¿ units look much different than the unit in this pr.Due to the lack of additional information, and the inability to reproduce the rounded edges failure, root cause cannot be determined.The root cause is undetermined and was unable to be confirmed in the complaint evaluation.A device history record (dhr) review and trending were performed as part of the evaluation.Proper finished goods testing was performed prior to release as indicated in the dhr.Product was received for analysis and the investigation could confirm the complaint.Possible root cause per the failure analysis performed is that the drill likely came in contact with a surface other than the patients skull during surgery which caused the drill bit to dull.Additional information received: - did the physician determine the unit was ¿dull¿ on the 1st burr hole? unknown - what other fixtures / instrumentation was being used alongside the perforator (ex.Clamps, retractors, etc.)? unknown - was there any unexpected drilling / nicking of any surface other than the patient¿s skull using the 1st unit? unknown.
