No anomalies by checking the dhr of the lot # of instrument involved ((b)(4)).No other similar complaints registered on this lot #, on a total of (b)(4) instruments manufactured with these lot #.Despite of the initial info provided, we did not receive the instrument involved so we could not analyze it.An analysis on another similar issue occurred in (b)(6) on a similar instrument with model # 9013.02.303 (lima complaint # (b)(4), mfr report # 3008021110-2015-00023) showed that the likely cause of the pin loosening was a slight dimensional anomaly on the pin and on the corresponding hole of the impactor (i.E.Slight under-dimensioning of the pin diameter and slight over-dimensioning of the hole diameter).In february 2015, before becoming aware of this type of complaint, a slight adjustment (a reduction) in the tolerances of the pin holes in the impactor body was made which reduces the risk of occurrence of similar issues.This adjustment was made for both the impactors 9013.02.302-9013.02.303.Excluding the 2 above mentioned cases (both instruments manufactured before the adjustment mentioned above), no other similar intra-op issues have been received on instrument part number 9013.02.302-9013.02.303.Lima corporate will continue to monitor complaints on these products.
