FIXATION DEVICES
2-PIN BAR FOR SAGITTILT®
ON A VARIAN IGRT COUCH
Article No. : 32070/17
A. GENERAL PRODUCT INFORMATION
This product is a fixation device to attach the Sagittilt®Prone
Breast Solution to a Varian IGRT couch top with the Exact type
indexing.
This product may only be used in combination with Orfit
immobilisation products. Orfit prohibits the use of unauthorised
third-party products in conjunction with its own products.
B. PRODUCT DESCRIPTION
This fixation device features two positioning elements that can
be inserted in the half-moon cut-outs on both sides of the
Varian IGRT couch. It also features two pins on top that are
used to index the Sagittilt®Prone Breast Solution directly to the
couch. Information on the Sagittilt®Prone Breast Solution can
be found in the respective ‘instructions for use’ and on
www.orfit.com.
C. POSITIONING ON A COUCH
The two round positioning elements of this fixation device fit
directly in the cut-outs of the Varian IGRT couch. The bar has an
offset of 20mm which should be placed towards the cranial end
of the couch to make sure the caudal part of the Sagittilt®Prone
Breast Solution fits completely on the table.
To position this 2-pin bar on the Varian IGRT couch, gently push
the bar with its two indexing elements into a set of couch cut-
outs. The bar itself should now be flat on the surface of the
couch. Always make sure that the bar is well positioned on the
couch before positioning the Sagittilt®Prone Breast Solution
over the 2-pin bar.
To remove the bar, hold the two ends of the bar and pull the
bar away from the couch.
To assist in mounting the Sagittilt®onto the couch:
•Mount the first 2-pin bar into the 7th indexing cut-out
of the Varian IGRT couch, starting from the caudal
side.
•Mount the second 2-pin bar on the couch so you can
count 5 couch indexing cut-outs between them. This
way, both 2-pins bars are positioned at the correct
distance from each other to match the entire
Sagittilt®setup.
•Use the markings on the 2-pin bar to easily align the
Sagittilt®.
D. STORAGE
Always store the product in a safe place to prevent it from
