This report is being supplemented to provide additional information based on the legal manufacturer's final investigation and device evaluation.Correction to the g3 of the initial medwatch.The aware date should be 21aug2024.Please see corrected data in field b5 for information inadvertently left out of previous report.Also find corrected data in fields d5, e1, e2 and e3 and h6 (health effect-impact code) a review of the device history record found no deviations that could have caused or contributed to the reported issue.Based on the results of the investigation, it is likely that the operation wire was damaged or fell off and came off from the operation wire fixing hole of the cup because a strong load exceeding the bearing strength was applied to the connection part between the operation wire and the cup.However, a definitive root cause of the reportable issue could not be determined.The suggested event is detectable and preventable by handling device in accordance with the following instructions for use (ifu): ·do not open or close the cup with excessive force.Doing so may result in damage to the biopsy forceps.·do not pull out the biopsy forceps while the endoscope angle is applied.The operating wire of the biopsy forceps may detach from the cup.If the operating wire is disconnected, the disconnected wire may protrude, resulting in perforation, bleeding, or mucosal damage.·if the operating wire comes off the cup, stop using it immediately.If the operation wire comes off the cup, the slider may lose resistance or become stuck.If the operating sensation changes, make sure that the operating wire is not dislodged from the cup.In addition, if the operating wire comes off after inserting the biopsy forceps into the endoscope, pull the slider to your hand, pull the biopsy forceps to the tip of the endoscope, and pull the biopsy forceps and endoscope together while taking care not to scratch the body cavity while looking at the endoscopic image.·do not insert forcibly, insert without closing the cup, or insert abruptly.It may protrude sharply from the tip of the endoscope, leading to perforation, major bleeding, mucosal damage, or damage to the endoscope or biopsy forceps.Also, if the resistance is large and it is difficult to insert, return the angle of the endoscope or forceps to the point where it can be inserted without difficulty.¿ never use excessive force to open or close the cups.This could damage the instrument.¿ if the manipulation wire becomes detached from the cups, immediately stop using the instrument.With the wire detached, you may feel little or no resistance when moving the slider, and your impression of the manipulation of the instrument may differ significantly from what is actually taking place.If you notice any major changes in manipulation, check whether or not the wire has become detached from the cups.·if the manipulation wire becomes detached while the biopsy forceps are inserted in the endoscope, first move the slider all the way in the proximal direction in order that the cups may come as close to the distal end of the endoscope as possible.Then, withdraw the biopsy forceps and the endoscope together from the patient¿s body with extreme care to avoid causing patient injury.At the same time, make sure that no part of the manipulation wire has fallen into the patient¿s body.¿ do not force the instrument if resistance to insertion is encountered.Reduce the endoscope¿s angulation (or lower the forceps elevator if applicable) until the instrument passes smoothly.Attempting to force the instrument could cause patient injury, such as perforation, bleeding, or mucous membrane damage.It could also damage the endoscope and/or instrument.Olympus will continue to monitor the field performance of this device.
