As the device did not show any deviation that could cause the reported incident and due to the customer has informed us that he suspects a user error as the cause of the reported incident we suspect, that maybe the pinning technique has been not optimal as described in the instruction manual: "adjust the skull clamp to the width of the patient's head in the manner that the two skull pins in the rocker arm are equidistant from the centerline of the head and the single skull pin at the extension assembly is in line with this centerline.".
