A user facility reported to olympus that during unspecified diagnostic procedures, the disposable biopsy forceps was taking big "bites" out of the mucosa, causing bleeding.The physician was uncomfortable with the large sample.Some of the patients required hemostatic methods such as cautery or clips.The procedures were not delayed due to the issue and the outcome of the procedure was unaffected.This event requires two reports.Patient identifier (b)(6) is for an individual patient.Patient identifier (b)(6) is for "some patient's" of unknown quantity.

This report is being supplemented to provide additional information based on the legal manufacturer's final investigation.Correction to h6 problem code.Multiple attempts were performed to obtain additional information, but no response was received from the customer.The subject device was not retuned.On june 2, 2023, the customer returned an unused device, and it was confirmed that the unused device presented no abnormalities.There are no signs of physical damage or mishandling on the box or to the product itself.Olympus performed a functional check.When manipulating the slider, the jaws opened and closed smoothly and without any restrictions.Jaws are new and intact.A review of the device history record (dhr) found no deviations that could have caused or contributed to the reported issue.Based on the results of the investigation, bleeding was probably caused by a large gnawing of the mucous membrane.Additionally, no abnormalities were detected in the dhr.Therefore, it is determined that abnormality of the device was not the cause of the reported event.It is possible that the forceps did not resect the mucosa well enough and that a large gnawing of the mucosa occurred.The failure of the forceps to firmly resect the mucosa could be due to the following factors: - the approach to the tissue was poor and the tissue was not pressed against the tissue sufficiently.- the tissue was difficult to resect.- the cup did not close completely due to excessive grasping.Since olympus was unable to check the actual product, a specific cause of the problems could not be determined.The event can be detected by following the instructions for use which state: - "do not force the distal end of the insertion portion against body cavity tissue.Doing so could cause patient injury, such as perforation, bleeding, or mucous membrane damage." - "biopsy may cause bleeding.If you take a large sample or press the instrument¿s distal end against tissue excessively, the risk of bleeding will increase.Perform biopsy on minimum necessary spots only." olympus will continue to monitor field performance for this device.
