23 Jul ELEMENT FOR HELPING BONE TISSUE AND/OR CONNECTIVE TISSUE GROWING INTO IT AND PROLIFERATING AND METHOD FOR MANUFACTURING IT
Abstract
FIELD: medical engineering. SUBSTANCE: device has element like grain promoting bone tissue and/or connective tissue to grow into and proliferate. The element is composed of plastic and insignificantly flexible biologically compatible material preferentially metal or metal alloy. The element is porous and has the following porosity properties: a) porosity is uniform; b) internal dimensions of pocket cavities (recesses) and canals connecting them to each other are 50 mcm in width for bone tissue and more than a value like 10 mcm for connective tissue. Method for producing the element involves forcing gas through molten metal by bubbling with automatic separation of grains or granules not satisfying requirements on porosity. The internal dimensions of pocket cavities (recesses) and canals/passages connecting them to each other are 50 mcm in width in this case. EFFECT: increased bone tissue growth rate. 12 cl, 3 dwg
