Description
The MAYFIELD Innity XR2 Base Unit is designed to provide attachment from the operating room
table to MAYFIELD Skull Clamps for rigid skeletal xation or MAYFIELD Horseshoe Headrests for
procedures where support only is required and not rigid xation. The XR2 Base Unit is designed
for patient positioning in the prone, lateral or supine positions for attachment to either a skull
clamp or a horseshoe headrest. It attaches to the OR table side rails with easy adjustment for
tables of a variety of widths.
The Innity XR2 Base Unit is suitable for Digital Subtraction Angiography (DSA), Fluoroscopy and
CT imaging modalities.
The components of the XR2 Base Unit are color-coded for easy assembly for use and disassembly
for cleaning and storage. A separate storage case is provided with the base unit for safe-keeping
between procedures and for use to ship the product in for repair or maintenance.
A separate, optional Tri-Star Swivel Adaptor (A2111) is available for use with the XR2 Base Unit
when image-guided surgery (IGS) systems are used in the procedures. The Tri-Star Swivel
Adaptor provides two extra starbursts for attachment of the ancillary IGS equipment. See the
separate Instruction Manual for the A2111 for information.
The Innity XR2 Base Unit is designed for use with the following equipment:

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 be brought up for attachment.
1. 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.
2. Securely fasten the skull clamp to the MAYFIELD base unit by attachment to the Swivel
Adaptor. Close Locking Levers. Turn clockwise all of the Locking Knobs of the other
components of the base unit making certain all starburst teeth are fully meshed (where
applicable) on all joints of the base unit after adjustments are complete.
CAUTION!
Before fully tightening, always be certain that the starburst teeth of the Swivel
Adaptor and other starburst ttings are the same size and properly mesh.
Failure to do so may damage ttings. Figure 5 shows a typical starburst
connection and proper meshing of teeth.
