FIELD: medical equipment, in particular, devices for surgical treatment of injuries and diseases of the vertebral column. SUBSTANCE: the intervertebral distractor has supporting plates and extensible members. The extensible members consist of two pairs of levers 1 of a different length that are connected on axles in the form of a rhomb. The upper 5 and lower 6 supporting plates with tenons are attached on axles to one pair of levers. A guide strip and a nut with two threaded holes for screws 10 are attached to the other pair of levers. EFFECT: the bodies of vertebral can be extended at large angular and axial displacements, and in the absence of one, two vertebral a constant distance of distraction can be maintained; the danger of spontaneous displacement and decrease of the distance between vertebral is eliminated. 5 dwg
