Abstract
The surgical aid endowed with osteotropic activity comprises a base and a suspended substance constituting the active element dispersed in the base. The active element is constituted by granular, ceramic hydroxy-apatite, and the base is gelatine of pharmacologic grade in a pure state, to which glycerol is possibly added. The aid is used in anhydrous phase, and as thin sheets and filaments, the flexibility of which increases with increasing percentage of glycerol in the base.
Claims8
A surgical aid endowed with an osteotropic activity, characterized in that it comprises a base and a suspended substance, which constitutes the active element, with said base being constituted by gelatine of pharmacologic grade, in a pure state, and the suspended matter being constituted by ceramic hydroxy-apatite dispersed in the base, said surgical aid containing glycerol and being prepared in two successive phases, said two phases comprising an intermediate hydrate phase and a final anhydrous phase, with said hydrate phase substantially comprising:
- ______________________________________ hydroxy-apatite 61.35% gelatine 13.56% glycerol 12.65% water 12.44% ______________________________________
- and said anhydrous phase substantially comprising:
- ______________________________________ hydroxy-apatite 70.00% gelatine 15.05% glycerol 14.04% water 0.91%. ______________________________________
