ENGLISH
Description
The MAYFIELD® Triad Skull Clamp (REF A-1108) is designed
to give rigid skeletal fixation, allow the surgeon more
freedom in positioning the fixation pins and show
indication of pin force. Avoidance of critical areas of the
skull is made possible by a swiveling rocker arm, which
rotates 360 degrees, making application much easier.
The swivel rocker arm can rotate 360 degrees under full
skeletal pressure after pin impingement, making final
patient positioning safer and easier.
The MAYFIELD Skull Clamp requires the use of three (3)
each MAYFIELD Skull Pins.
