Indications for Use/Intended Purpose/ Description

locked position without a transitional member in its receptacle (Fig. 2). Failure to do so may result in damage to the equipment.

The MAYFIELD® Ultra Base Unit (REF A2101 or A2102) is designed for patient positioning in the prone, supine, and sitting positions. The MAYFIELD Ultra Base Unit can be easily readjusted to fit most operating tables. It is used in conjunction with the MAYFIELD Ball Socket Swivel Adaptor (REF A1064), the MAYFIELD Swivel Adaptor (REF A1018), or the MAYFIELD Tri-Star Adapter (REF A2008) for attachment of various MAYFIELD Neurosurgical Headrests and Skull Clamps. The MAYFIELD Crossbar Adaptor (REF A1015 or A1016) and the MAYFIELD Universal Side Rail Fitting (REF A1060) are required for the sitting position.

NOTE: It is important to periodically adjust the tension of the Locking Lever to compensate for changes which occur with normal usage.

Care and Handling 1. Release Locking Lever by pulling upward (Fig. 1). 2. Remove the Adjustment Wrench from its receptacle on the right End Bracket by turning counter-clockwise. 3. Insert the Adjustment Wrench into the Lock Screw located at the center of the Tension Knob at the base of the Base Handle (Fig. 3). Turn the Adjustment Wrench counterclockwise several turns in order to unlock the Tension Knob.

The End Brackets of the MAYFIELD Ultra Base Unit are equipped with internal isolation caps to help provide insulation against stray electrical current.

4. Turn the Tension Knob counter-clockwise to loosen tension or clockwise to tighten tension on the Locking Lever.

NOTE: The MAYFIELD Neurogen Adaptor (REF A1113) may be required for those operating tables not designed to accept the MAYFIELD Ultra Base Unit. (REF A2101 or A2102). The MAYFIELD Ultra Base Unit (Fig. 1), is supplied with an Adjustment Wrench (REF 41A1284), and a 6” Transitional Member (REF 41B1171).

5. Test the tension on the Locking Lever by depressing and releasing the Lever. Movement should be smooth, but firm. 6. Test stability by placing the Base Unit on top of the O.R. Table. In the unlocked position place the Base Handle and Transitional Member in a straight line of 45° to the table and depress the Locking Lever (Fig. 4). Exert pressure in a downward direction on the Transitional Member. No movement should be observed.

Intended Population

7. Re-lock the Tension Knob by turning the Adjustment Wrench clockwise within the Lock Screw (Fig. 3).Return the Adjustment Wrench to its receptacle.

MAYFIELD Skull Clamp fixation devices are not recommended for use on children under five (5) years of age. Extreme caution should be exercised in pediatric cases because of the thin skull.

NOTE: Over a period of time, the Shock Cushion within the Base Handle may become deformed (Fig. 2). Deformation of the Shock Cushion, visible just below the Locking Lever, is normal and will not affect the operation of the Base Unit. However, deformation of the Shock Cushion in the interior of the receptacle will prevent insertion or ease of movement of the Transitional Member in the receptacle. To prevent this type of deformation, always store the MAYFIELD Ultra Base Unit with a Transitional Member in its receptacle and the Locking Lever depressed (Fig. 2).
