Adjustable Holder with Base for Dilators with Stem Scale
This CT/MR Conditional Adjustable Holder with Base for Dilators with Stem Scale was designed to be used when treating anal cancer in females with chemoradiation. The use of a dilator is used to delineate and displace the vulva and lower vagina away from the primary tumor with the intention of decreasing dose to these areas.
The vertical post scale on the holder ranges from 2.5cm to 15cm and allows for reproducing from day to day the vertical position of the dilator. The dilator can also be angled up or down in the anterior - posterior position with a scale marked every 5° to 45° and a locking thumb screw. All dilators are 6.5" (16.5cm) long, not including stem. The dilators have a scale on the stem that ranges form 1cm to 7cm which is used for depth.
Because the base that this item includes is made entirely from ertalyte plastic, it is completely CT/MR safe. The base can be set into position in the vacuum cushion that is used for positioning the patient legs. This will give a reproducible base location on a daily basis.
Item 946-200 includes only the Holder and base.
