Warnings
Failure to read and follow instructions and warnings furnished in this instruction manual and the instructions and warnings included in the associated skull clamp instruction manual may result in serious patient injury. The skull clamp must be applied along a centerline of the patient's head with pins entering the skull perpendicularly. Failure to properly position the skull clamp on the patient's head could result in patient injury such as scalp laceration due to skull pin slippage. Failure to properly position patient and to fully secure all adjustment positions of the skull clamp or support device may result in patient injury. Do not use the MAYFIELD^® Titanium Skull Pins with the Original GARDNER brand Skull Clamp. These skull pins are not recommended for use on children under five (5) years of age and extreme caution should be exercised in pediatric cases because of the thin skull. MAYFIELD Titanium Child Skull Pins (A1122) are recommended for young children over the age of five (5) years. It is at the discretion of the user, when the adult of child skull pins should be used. These pins are provided non-sterile. The reusable skull pins should be steam sterilized before each use. It is recommended that a second set of sterile pins be kept available in case sterile technique is compromised. Never resharpen skull pins. Dull or bent pins should be discarded and replaced. Do not confuse titanium skull pins with steel pins. Steel objects passing through high intensity magnetic fields can generate enough heat to burn tissue. The adult titanium skull pins has been colored "gold" and the cylindrical portion of the body has several flat surfaces to be used as visual cues that the pin is made of titanium. Child pins have a unique shape to make them readily distinguishable from the adult pin points. Before using this product, carefully read the product insert for correct use and warnings associated with the specific skull clamp model intended to be used. Do not position the skull pins over the frontal sinuses or the temporal area of the skull. Take care to avoid major blood vessels, nerves, previously restored or abnormally thin bone.


Cautions
Inspect reusable skull pin points carefully prior to each use. To achieve proper fixation, pins should be of equal length. Broken, dull, or bent pins should be replaced. It is recommended that a spare set of pins always be kept available. Hold the skull pins between the thumb and forefinger at the base of the pin. Insert the pins into the skull pin receptacles on the skull clamp. Push them in until they are seated firmly and cannot be inserted any further into the receptacle. The skull pins must be fully seated so there is no gap between the shoulder of the skull pin and the skull clamp. Make sure the trajectory of the single Pin in the Skull Clamp intersects the center of the patient's head and the Rocker Arm to correctly secure the patient's head into the Skull Clamp. Skull Pins should enter the scalp at a 90° angle. 60 lb. (267 N) of force is recommended for adults. 40 lb. (178 N) of force is recommended for children. All force settings are at the user's discretion. Never exceed 80 lb. (356 N) of force. Remove single-pin holder or skull clamp extension from the skull clamp prior to skull pin removal. This will minimize chance of injury during skull pin removal. Grasp skull pin between thumb and forefinger. Pull skull pin outward and away from receptacle.
