THE SURGEON REMOVED THE FRAGMENT BY USING A GRASPER, DURING THE SAME PROCEDURE. THE INSTRUMENT WAS INSPECTED PRIOR TO USE WITH NO DAMAGE FOUND. DURING A DA VINCI-ASSISTED THYROIDECTOMY SURGICAL PROCEDURE, THE INSTRUMENT BROKE WHILE IT WAS BEING USED FOR DISSECTING TISSUE. ALL THE FRAGMENTS WERE RETRIEVED UPON VISUAL INSPECTION.
