XR2 Metal-Free Conversion Accessory (Optional)
This accessory provides the surgeon the opportunity to remove a potential source of imaging artifact
associated with the torque screw that has metal parts to supply the controlled-force to the skull
pins. This accessory includes a special Ratchet Extension that allows for the use of the optional Force
Applicator (439A1093).
Removable Torque Screw (Optional)
This removable Force Applicator can develop up to 80 lbs. (356 N) of force; graduated in 20 lbs. (89 N)
increments. The removable Force Applicator is as shown below in Figure 12. This Force Applicator can
be detached after the force is applied and before scanning; thereby removing a potential source of
imaging artifact.
NOTE: This removable Force Applicator requires a specially designed ratchet extension that is part of
the optional XR2 Metal-Free Conversion Accessory.
