Attachment of The Skull Clamp to The Base Unit
Once the Skull Clamp is applied to the patient's skull, the surgeon will maneuver the patient to the
surgical position that is required for the procedure. With the patient in this position, the surgeon will
hold the patient's head and the Skull Clamp and request that the components for the Base Unit to be
brought up for attachment.
1. The Base Unit (A1079, A2079), with all components, should be attached to the operating room
table with the side rail clamps securely tightened. All linkage components (Yoke, Transitional
Members, Links, Swivel Adaptors) should be attached but not fully tightened. The starburst
teeth should not be engaged. All components should move freely for easy positioning for
attachment to the Skull Clamp.
2. The attached but loose components of the Base Unit should be brought up for attachment to
the Skull Clamp. The mounting screw of the large starburst on the swivel adaptor should be
inserted into the large starburst of the Skull Clamp and turned clockwise and tightened. Care
should be taken to maintain the position of the patient's head as requested by the surgeon.
3. Securely fasten the Skull Clamp to the MAYFIELD Base Unit by attachment to the Swivel
Adaptor. Turn clockwise all of the Locking Knobs of the other components of the Base Unit
making certain all starburst teeth are meshed (where applicable) on all joints of the Base Unit
after adjustments are complete.
Before fully tightening, always be certain that the starburst teeth of the Swivel
Adaptor and the Transitional Member fittings are the same size and properly mesh.
Failure to do so may damage fittings. Figure 10 shows a typical starburst connection
and proper meshing of teeth.
