Abstract

En ryggradskrok (10) som omfatter en krokformet sko (11) med et i ett stykke .dannet toppart! (15). Toppartiet (15) omfatter to sentrale søyler (17) som er forskjøvet for å danne en sliss (19) derimellom. Hver sentral søyle omfatter et spor (22) som kolineært formet for å oppta en ryggradsstang i dette. Slissen mellom de to søyler er orientert i for- hold til sporene slik at en øyebolt- montasje (E) kan benyttes til å tilkople kroken til fikseringsstangen. Ifølge en annen side ved oppfinnelsen er en sliss (25) dannet i krokens endeflater (28). Slissen danner den ene del av en tunge- og slissanordning for instrumenterings- tilkopling, idet det krokholdende instrument omfatter en tilsvarende ut- formet tunge. Ifølge en annen side ved oppfinnelsen omfatter hvert av paret av sentrale søyler (17) spor (22) på begge sideflater (27) av søylene, slik at ryggradsstangen (29) kan være beliggende på den ene eller den andre side av rygg- radskroken (10).
