COMPOSITE CARBON NANOMATERIAL FOR BONE DEFECTS REPLACEMENT, METHOD OF ITS MANUFACTURE AND IMPLANT OF COMPOSITE CARON NANOMATERIAL Russian patent published in 2017 - IPC A61L27/08 B82B1/00 A61F2/28 A61F2/44 

FIELD: medicine.

SUBSTANCE: composite carbon nanomaterial for bone defects replacement is described, comprising pyrocarbon matrix and fibrous reinforcing framework made in the form of a skeleton with bars containing carbon fibres oriented along the bar axis and containing vertically installed bars and horizontal layers, each of which is formed parallel to the oriented bars, while the bars of each layer are oriented relative to the bars of previous and subsequent layer at an angle of 60°, wherein the average size of graphite-like fragments in material structure is less than 30 nm, the method of obtaining material comprising pyrocarbon matrix and omnidirectional reinforcing skeleton with bars made of carbon fibres, located along the bar axis is also described, wherein the implant material has an elastic modulus of not more than 15GPa, material open porosity is not less than 5 vol. %, and the average size of graphite-like fragments in material structire does not exceed 30 nm.

EFFECT: material and its implants for bone defects replacement have mechanical properties similar to the bone properties.
