Manufacturer Narrative

Investigation results: visual investigation: the instrument shows signs of tanning such as scuff marks and changes in colour of the plastic handle.The front spiral part of the instrument is broken off.The fracture surface of the instrument was visually examined.A tough bending force fracture was found, which can be attributed to an overload.A definitive fracture analysis is hardly possible, as the fracture surface of the missing broken part should also be considered.Batch history review: the device quality and manufacturing history records (dhr) will be checked for the leading device(s) lot number(s) from the quality coordinator of the production plant.The results of the review will be documented.If the review shows any conspicuities, the report will be updated and actions will be initiated.There are no similar complaint against the same lot number(s) with this error pattern.The review of risk assessment revealed that the overall risk level (severity 3(5) x probability of occurrence 1(5) according to din en iso 14971 is still acceptable.Explanation and rationale: based on the investigation results, no pores or inclusions could be found at the point of breakage.Conclusion and measures / preventive measures: based upon the investigation results, a clear root cause conclusion cannot be determined.There is no indication for a material-, manufacturing- or design-related failure.Based upon the investigations results a capa is not necessary.
