FIELD: medical engineering, traumatology, orthopedics, surgical treatment of vertebral column by removing vertebral body. SUBSTANCE: connecting elements intended for fixation of vertebral prosthesis are made in from of flat dowels (7) sharpened on one side. Dowels are arranged along edges of support platforms (6) and covered by protective caps (8) provided with cuts (9) arranged so as to match dowels (7). There is also provided sleeve coupling (1) having positioning screws (3) which can by secured to one side of coupling (1) thereby enabling rotational movement of vertebral column. EFFECT: facilitated introduction and positioning of vertebral prosthesis in required position; reliable and stable fixation of prosthesis. 1 dwg

Изобретение относится к медицинской технике, преимущественно к травматологии, ортопедии для хирургического лечения позвоночника при удалении тела позвонка. Цель: облегчение введения и установки протеза позвонка в необходимое положение в операционном поле и обеспечение надежной, устойчивой фиксации протеза. Сущность изобретения: соединительные элементы для крепления протеза позвонка выполнены в виде плоских шипов 7 с односторонней заточкой, размещенных по краям опорных площадок 6 и прикрытых защитными колпачками 8 с надсечками 9, расположенными соответственно размещению шипов 7, а стопорные винты 3 располагаются и закрепляются с одной стороны муфты 1, при сохранении возможности вращения позвоночника. Предлагаемый протез тела позвонка удобен при установке его в операционном поле, что обеспечивает надежную фиксацию и возможность вращения позвоночника.
The invention relates to medical equipment, mainly to traumatology, orthopedics for surgical treatment of the spine when removing the vertebral body. Purpose: facilitating the introduction and installation of the vertebral prosthesis in the required position in the surgical field and ensuring reliable, stable fixation of the prosthesis. The inventive connecting elements for fastening the prosthesis of the vertebra is made in the form of flat spikes 7 with one-sided sharpening, placed along the edges of the support pads 6 and covered with protective caps 8 with notches 9, located respectively to the placement of the spikes 7, and the locking screws 3 are located and fastened on one side couplings 1, while maintaining the possibility of rotation of the spine. The proposed prosthesis of the vertebral body is convenient when installing it in the surgical field, which provides reliable fixation and the possibility of rotation of the spine.
