B5 - addition of concomitant component, pin cutter used to remove pin (original description: the clamp came off when the skull was fixed and the pin was finally cut with a cutter).General information: intra operative incident.Up to now there is no product available for analysis.Consequences for the patient: according to the available information there were no negative consequences for the patient.Investigation: no product at hand.Only pictures received, which described in rationales.Batch history review: the manufacturing documents have been checked and found to be according to specification valid during the time of production.There is no further complaint with this lot at hand.Conclusion and root cause: the root cause for the problem is most probably usage related.Rationale: without a product available for analysis it is very difficult to make a reliable statement.As seen in the provided pictures - the cutting edges of the pin rest and the pin at the lower disc don't fit together.The spring segments of the come off upper disc appear bent uneven.This and the skewed cutting of the rest pin can be a hint for a skewed attached disc.We assume the lower disc and the pin rest not belong together.The fact that there are no further complaints with this lot at hand and the device history recording is found to be according to the specification we assume an usage related error, as in many previous complaints of the same type we investigated with products in the past.A material failure or a manufacturing error can be excluded.Corrective action: according to sop sa-de13-m-4-2-04-000-0 (corrective action & preventive action) a capa is not necessary.

Investigation results: the device was received for investigation.The implant arrived in a detached condition, the pin was cut and the upper disc was loosened from the pin rest of the lowe disc.Investigation, especially of the cutting edges of the pin and the spring segments of the upper disc, was carried out visually.The spring segments of the upper disc are bent uneven.The juxtaposition of the cutting edges produce the evidence that the pin rest and the lowe disc belong together.The manufacturing documents have been checked and found to be according to specification valid during the time of production.There is no further complaint with this lot at hand.The root cause of the problem is most probably usage related.The spring segments of the come off upper disc appear bent uneven.This is a hint for a skewed attached disc.Against our assumption in the previous report ("we assume the lower disc and the pin rest not belong together") prove that the pin rest and the lower disc belong together.We assume an usage related error.A material failure or a manufacturing error can be excluded.A capa is not necessary.
