IMPLANT FOR SURGICAL TREATMENT OF THE DEFECTS OF BONE AND CARTILAGINOUS TISSUE

摘要

ESSAY; The invention relates to medicine, namely to traumatology and orthopedics. The implant is a volumetric three-dimensional structure made from polycaprolactone having a porous substrate and supported on its outer surface at least partially reticulated skeleton. The latter is made from a nanostructured material and is molded of a chaotic stacking of the fibers. The polycaprolactone skeleton introduced particles of hydroxyapatite or calcium carbonate. Composite elements of the implant have the following parameters: diameter volokna- 50-500 nm; porous substrates of 90%; the maximum thickness of mesh frame - 500 microns; foundations thickness - 0.5-5 mm. Application utility model allows for as soon as possible the integration of the implant with the surrounding tissue pathological center due to the adhesion and proliferation in the mesh skeleton of tissue cells with an increase in the strength properties of the newly forming tissue. 1 head. n. f ly-1 pr., 2 yl.
