The fiber cystoscope 15 ch iml 400mm, part id: 7305.001, with the serial number (b)(6), was produced on 30/aug/2019 under order number (b)(4).The order size was (b)(4) pieces.There were no anomalies during production and the entire batch successfully passed the final inspection.The fiber cystoscope 15 ch iml 400mm was delivered to the customer on 28/nov/2019.On 07/aug/2023 instrument was in house for repair.The unwinding was repaired and the instrument was sent back to the customer on 05/oct/2023.The current complaint (b)(4) refers to cloudy vision, here the fault can be attributed to insufficient cleaning.The repair with the repaired processing can be excluded as a subsequent fault.A query on comparable complaints has revealed that there have only been 2 comparable cases in the last 3 years.Also, no other serial numbers from production order (b)(4) were complained about.At the same time, (b)(4) units were sold worldwide in the same period.A general product problem can therefore be ruled out.The fiber cystoscope was examined by the specialist department and it was found that the glass plates on the outside of the eyepiece were fogged up.This defect is seen in connection with inadequate reprocessing.In the corresponding instructions for use ga-j050/2014-05 v7.0/pdi 13-6891 and ga-s006 /en/2019-05 v14.0 / pk18-9407, reference is made to visual and functional checks in chapter 7 "inspection and maintenance" (ga-j050) and chapter 9 "checks" (ga-s006).Possible hazards have been identified in risk assessment a3: "reusable flexible optics", document number 10000309115 ver.00, under chemical hazards: anesthetic agents, under ageing damage due to reprocessing or use as acceptable and taken into account with the corresponding extent of damage and probability of occurrence.In summary, we can say that this batch has no general product problem.The associated instructions for use refer to the service life and correct reprocessing and inspection of the products.The defect can be traced back to cleaning/care errors.This error can be easely detected prior use.
