The subject device was returned to omsc for evaluation.As the result of evaluation, the loop was caught in between the cutter and the loop hanger.The manufacturing history record was reviewed, with no irregularities noted.Based on the past similar cases, it is assumed that the event occurred because the doctor pulled the slider without positioning the loop vertically to the loop hunger.The instruction manual of the device has already warned as follows; -do not try to cut the loop that is not positioned on both edges of the loop hanger as plumb as possible for the blade.It may make cutting the loop impossible, or result in the loop getting caught in the distal end of the instrument, which could make it difficult or impossible to remove from the patient.In this case, use pliers to cut the insertion portion of the instrument where it extends from the biopsy valve of the endoscope.Remove the endoscope from the body, then reinsert the endoscope and cut the loop with a spare loop cutter.
