FIELD: medicine.
SUBSTANCE: invention relates to surgery and can be used for introduction of contrast into sinus tract in performing fistulography under X-ray or computer tomographic control. Device for fistulography is made from X-ray-positive material, has conic shape and contains adaptor with connector for syringe and lock unit with lever for regulation of liquid supply. Cone is made in form of cannula for hermetic connection with sinus tract and has, as minimum, two prominent notches in form of radial projections for adjusting cannula to diameter of external fistula opening.
EFFECT: device reliably ensures leak-tightness in introduction of contrast for sinus tracts with external fistula openings of different diameter.
