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 parts of the cone are disposed inside hollow part for axial displacement and exit and is connected with outer edges of hollow part by means of stretched elastic membrane. Membrane is fastened at the side of proximal section. Monolithic cone has its base to be connected with elliptic springs. Springs are mounted in perpendicular to each other to have their other ends to be fastened to cylindrical part. Hollow part has convex shape designed for reducing and increasing diameter. Device restores permeability of clear space of gullet at any solid afternidus strictures.
EFFECT: improved efficiency of operation.
