FIELD: otolaryngology.
SUBSTANCE: device for restoring gullet permeability has polymeric base with hollow part, cone-shaped distal section and cylindrical part. Distal section is made in form of monolithic cone having lateral channel for thread. Two thirds of monolithic cone are disposed inside hollow part for axial displacement and exit. Cone is circularly connected with outer edges of hollow part by stretched elastic membrane. Membrane is fastened proximal section of monolithic cone. Base of monolithic cone is connected with flat lateral spring having turns. End of spring is fastened to hollow part. Conic part has convex shape and is made for reducing and increasing diameter. The other end of spring is fastened to cylindrical part. Device allows to restore permeability of gullet at any solid afternidus strictures available.
EFFECT: improved efficiency of operation.
