CAUTION!
Make sure the trajectory of the single pin in the skull clamp intersects the center of
the patient’s head and the rocker arm to correctly secure the patient’s head into the
skull clamp.
4. Proper fixation to the skull requires selection of the appropriate length piston and
engagement shaft. (See Figure 12
below.) The engagement shaft should be inserted
near flush with the exterior face of the threaded housing. The appropriate piston
length should be threaded into the engagement shaft until the skull pin makes
contact with the skull. A Piston Driver is provided for use when the piston is difficult
to access.
