Abstract
Utstyr til bruk i forbindelse med osteosyntese ved hvirvel- søylen, spesielt til stabilisering av hvirvelsøylesegmenter, omfattende minst ett stavliknende forbindelseselement (14), minst to på hvirvelsøylesegnentet forankringsbare holdemidler (12) med et stemmegaffelliknende hode (15), hvis to ben (16,17) avgrenser et tilnærmet U-formet opptagningsrom (18) for forbindelseselementet (14), en klemmeskrue (19) som til befestigelse av forbindelsese- elementet (14) er innskrubart i opptagningsrommet (18) mellom de to ben (16,17) av det stemmegaffelliknende skruehode (15), idet bunnen (22) av opptagningsrommet (18) er tildannet konkav i tilordning til et mellom bunnen (22) av opptagningsrommet (18) og forbindelseselementet (14) anordnet svingelagerelement (23) hvis lagerflate (24) som vender mot bunnen (22) av opptagningsrommet (18) er tildannet komplementært konveks. Den lagerflate (24) av svingelagerelementet (23) som vender mot bunnen (22) av opptagningsrommet (18) er tildannet skallformet, spesielt halvkuleformet. Den ovec- forliggende side (25) som i montert tilstand vender mot klemmeskruen (19), har en not(26) til opptagelse av det stavformede forbindelseselement (14).Equipment for use in vertebral column osteosynthesis, in particular for stabilizing vertebral column segments, comprising at least one rod-like connecting element (14), at least two anchorable retaining means (12) on the vertebral column having a tuning fork-like head (15), two legs (16, 17) defines an approximately U-shaped receptacle space (18) for the connecting element (14), a clamping screw (19) which can be screwed into the receptacle space (18) between the two legs (16,17) by attaching the connecting element (14). the tuning fork-like screw head (15), the bottom (22) of the receiving chamber (18) being concave concave in relation to a pivot bearing element (23) whose bearing surface (24) is arranged between the bottom (22) of the receiving space (18) and the connecting element (14). facing the bottom (22) of the receptacle (18) is formed complementary convex. The bearing surface (24) of the pivot bearing element (23) facing the bottom (22) of the receptacle (18) is formed shell-shaped, especially hemispherical. The upper side (25) facing the clamping screw (19) in a mounted state has a groove (26) for receiving the rod-shaped connecting element (14).
