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 MAYFIELD 2 Base Unit (A3100, A3101, A3102), should be attached to the operating room
table with the Locking Handle unlocked and the Swivel Adaptor loose. In the event that other
MAYFIELD Base Units (A2009, A2101, A2001, A1001, A1000) are going to be used with the Skull
Clamp, be sure to also assemble a Swivel Adaptor (A1018, A2008) to complete the support
system for the Skull Clamp. Make certain to securely attach the base unit to the operating room
table.
2. The attached but loose components of the Base Unit should be brought up for attachment to
the Skull Clamp.
• Insert the mounting screw of the large starburst of the Swivel Adaptor into the large starburst
of the Skull Clamp.
• Turn the handle clockwise and tighten.
• Care should be taken to maintain the position of the patient's head as requested by the surgeon.
3. After securely fastening the Skull Clamp to the Swivel Adaptor turn the Index Locking Knob
to the locked position. Continue by checking all the locking knobs and locking handles of the
Adaptor and Base Unit making certain all starburst teeth are meshed (where applicable) on all
joints of the Base Unit after adjustments are complete.
