Event Description

According to the reporter, during the initial steps of lung volume reduction procedure, the device was not cutting sufficiently, knife blade did not advance and did not retract, and jaws eventually opened after multiple trials.The doctor clearly felt resistance to open the mouth of the device thoroughly.Upon examination, the nurse noticed that a metal object was clearly visible lodged behind the mouth of the device.No risk was taken and a new device was used successfully with the same generator.Upon inspection, it was found that the blade/knife was retracted insufficiently and could not be retracted anymore.But it does not protrude beyond the edge of the jaws.Additionally, device was cleaned continuously and very accurately.There was no patient injury.
