Abstract

Przedmiotem zgłoszenia jest stabilizator płytkowy, wewnętrzny, który posiada tulejkę zaciskową (5) dzieloną, o zewnętrznej powierzchni ukształtowanej w ten sposób, że jej średnica zewnętrzna jest zmienna wzdłuż osi tulejki. Tulejka zaciskowa (5) posiada gniazdo o kształcie kulistym lub zbliżonym do kulistego. W przypadku zastosowania więcej niż jednej płyty nośnej, stabilizator posiada nakrętkę kulistą (6) o kształcie kulistym lub zbliżonym do kulistego nakręcaną na wkręt (4). Zgłoszenie niniejsze obejmuje też sposób blokowania płyt nośnych względem odłamów kostnych oraz wzajemnie jednej płyty nośnej względem drugiej, który polega na tym, że tulejka (5) w czasie wciskania lub wkręcania w otwór w płycie (1) lub (2) zaciska się na łbie wkręta (4) lub nakrętki kulistej (6) o kształcie kulistym lub zbliżonym do kulistego.The subject of the application is an internal plate stabilizer, which has a split clamping bush (5), with the outer surface shaped in such a way that its outer diameter varies along the bush axis. The clamping sleeve (5) has a spherical or nearly spherical seat. If more than one support plate is used, the stabilizer has a spherical nut (6) with a spherical or nearly spherical shape, screwed onto the screw (4). The present application also covers a method of locking the support plates against bone fragments and one support plate to each other, which consists in the bushing (5) being pressed or screwed into a hole in the plate (1) or (2) clamped on the screw head. (4) or a spherical nut (6) with a spherical or nearly spherical shape.
