Event or Problem Description
The user facility reported that during a functional endoscopic sinus surgery (fess), the device did not work as intended.The burr had initially worked, then eventually stopped completely.A console and two (2) separate handpieces were used with the burr for testing, however the issue remained.The drill was taken from the handpiece and it was observed that part of the white piece of plastic in the drill where the drill is inserted into the handpiece was chipped up.The procedure was prolonged over an hour and was then aborted due to a lack of burrs.The patient had to be rescheduled for a new procedure.There was no patient harm reported.The device was inspected prior to the procedure and no damage or abnormalities were observed.The user facility later reported that the reason why the burrs broke was that they were used on a patient with an osteoma.The bone tissue was too hard for the burr to drill away.The rotation speed of the shaver became too small to handle this.The customer acknowledged that burrs were used in a procedure they are not intended to be used in.This complaint is related to patient identifiers; (b)(6).
