It was reported that when the drill bit was used for the first time, the left and right amplitude of swing were too large and it couldn't be used normally.The swing was too large, causing the bur to shake when in use.The issue was found out when the user was just using it during a frontal sinus surgery ( during installation stage ) and was not used on patient.There was a surgical delay of 3 minutes.There was no patient impact.The procedure was completed with backup products.
