CELLULAR STRUCTURE OF IMPLANTS Russian patent published in 2019 - IPC A61C8/00 A61F2/36 

FIELD: medicine.

SUBSTANCE: invention relates to additive technologies used for making implants, preferably, from titanium alloys. Cellular structure of implants is made in the form of volumetric grid with location of nodes on surface of spatial figures connected by jumpers. Spatial figure is hollow sphere, having wall limited by outer and inner spherical surfaces. In first diametric cross section of sphere there are first and second through holes having first common axis, in a plane orthogonal to said axis and at angle of 45° to first diametric cross-section there are third and fourth through holes having second common axis, in the same plane there are fifth and sixth holes having a third common axis which is orthogonal to the second common axis. Holes make main through channels. On surface of hollow sphere there are eight units arranged symmetrically relative to center of hollow sphere. Units have additional cells interconnected by additional channels.

EFFECT: invention improves elastic characteristics of the implant.
