Description
The MAYFIELD® MR/X-ray Skull Clamp with Table Adaptor (Catalog # A1117) is designed to provide
rigid skeletal fixation for procedures involving imaging modalities such as intra-operative MR,
CT, and digital subtraction angiography. This device is MR compatible* when used in the MR
environment at field strengths up to 3 tesla (T).
*MR Compatible is defined by the CDRH Magnetic Resonance Working Group (Feb. 7, 1997) draft
document A Primer on Medical Device Interactions with MRI Systems as “the device, when tested
in the MR environment, is MR Safe and has been demonstrated to neither significantly affect the
quality of the diagnostic information nor have its operations affected by the MR device.”
This system is comprised of the MAYFIELD MR/X-ray Skull Clamp (428C1000) and Table Adaptor
(428A1001). The MAYFIELD MR/X-ray Skull Clamp with Table Adaptor is designed for patient
positioning in the prone or supine positions. The Table Adaptor attaches to the Excite 3.0T diagnostic
table.
The MAYFIELD MR/X-ray Skull Clamp is designed to allow the surgeon more freedom in positioning
the fixation pins. Avoidance of critical areas of the skull is made possible by a swiveling rocker arm
which rotates 360°, making application much easier. In addition, the swiveling rocker arm can
rotate 360° under full skeletal force making final positioning after pin impingement much easier. Its
lean body design also allows for greater exposure to the operative site.
The MAYFIELD MR/X-ray Skull Clamp requires the use of three (3) each MAYFIELD Skull Pins.
(Available styles: A2020 MAYFIELD Radiolucent Skull Pins, A1120 MAYFIELD Titanium Disposable
Adult Skull Pins, A1119 MAYFIELD Titanium Disposable Child’s Skull Pin).
NOTE: The components of the MR/X-ray Skull Clamp are manufactured from plastic materials
which leave only a small artifact during intraoperative angiographic or radiographic procedures
using digital subtraction (D.S.A.).
CAUTION!
If any component is damaged or cracked, the complete system should be returned to
Integra for inspection and repair to assure the integrity of the composite components.
