Manufacturer Narrative

This report is being supplemented to provide additional information based on the legal manufacturer's investigation.Please see updates to d4, d9, h3, h4, h6 and h10.The suspect device has been returned to olympus for evaluation and the device evaluation is in process.Based on the results of the investigation, it¿s likely the reported event (cord severed/small burn hole in the drape/small puff of smoke) was due to wear and tear.It was determined that the cable may be damaged by strong mechanical stress occurring from regular use, for example by kinking the cable, winding it in a radius that is too small or by pulling on the cable instead of the plug.This may cause individual or all wires in the cable to break, which may result in the reported event.In order to reduce the occurrence of this error pattern, the period of use of the cable was limited to 12 months.However, a final root cause of this event was unable to be identified.The following is included in the instructions for use: ¿the service life of the cable is limited to 12 months.After this time, the cable should no longer be used.Additionally, the cable must be checked for damage before each use and after reprocessing.By gently pulling on the plug (max.20n), it can be determined whether the copper strand of the cable is already damaged.If the cable does not give way but remains rigid, the cable is most likely intact.In order not to shorten the service life of the cable any further, the cable should not be wound up with a loop diameter of less than 10cm and when pulling out the cable, the plug should be pulled and not the cable.¿ olympus will continue to monitor field performance for this device.

This report is being supplemented to provide additional information based on the legal manufacturer's final investigation and device evaluation.The device was returned to olympus for inspection, and the customer's complaint was confirmed.The hf-cable was not returned in its original packaging.The hf-cable was damaged and detached near the plug connector with the contact pin.The damaged portions of the cable were examined under a microscope, and it was observed that there were burnt and charred wires.Additionally, it was observed that the insulation was burnt and slightly melted.The rest of the hf-cable was inspected, there was no other cuts, tears, or kinks on the cable.The connectors appear to have no signs of physical damage or signs of burnt marks on the plugs.Functional testing of the cable was not performed due to the cable being damaged.A review of the device history record found no deviations that could have caused or contributed to the reported issue.It has been over 5 years since the subject device was manufactured.Based on the results of the investigation, it¿s likely the reported event (cord severed/small burn hole in the drape/small puff of smoke) was due to wear and tear in connection with improper handling.The cable may become damaged by strong mechanical stress occurring from regular use, for example by kinking the cable, winding it in a radius that is too small or by pulling on the cable instead of the plug.This may cause individual or all wires in the cable to break, which may result in the reported event.In order to reduce the occurrence of this error pattern, the period of use of the cable is limited to 12 months.However, a final root cause of this event was unable to be identified.The following is included in the instructions for use: "the service life of the cable is limited to 12 months.After this time, the cable should no longer be used.Additionally, the cable must be checked for damage before each use and after reprocessing.By gently pulling on the plug (max.20n), it can be determined whether the copper strand of the cable is already damaged.If the cable does not give way but remains rigid, the cable is most likely intact.In order not to shorten the service life of the cable any further, the cable should not be wound up with a loop diameter of less than 10cm and when pulling out the cable, the plug should be pulled and not the cable.¿ olympus will continue to monitor field performance for this device.
