Abstract
Inventia se refera la o proteza implantabila realizata dintr-o combinatie de polietilene prin procedee de prelucrare prin injectie si prin extrudere. Proteza are forma unui mosorel, tija fiind injectata din copolimeri ai etilenei cu n-di-butilmaleat, hexilmaleat, sau acetat de vinil, iar discurile plate circulare atasate prin termosudare cu capetele tijelor-fiind realizate dintr-un material textil netesut, tip "spunbonded", obtinut prin autolierea filamentelor extrudate din polietilena de joasa densitate cu fluiditate mare 200 g/10 min, la 160 degree C si 2,16 kg sau dintr-un copolimer al etilenei cu 40% hexilmaleat avînd un indice de fluiditate cuprins între 15 si 30 g/10 min. (La 160 degree C si 2,16 kg).The invention relates to an implantable prosthesis made of a combination of polyethylene by means of injection molding and extrusion processes. The prosthesis is in the form of a spindle, the rod being injected from ethylene copolymers with n-di-butylmaleate, hexylmaleate, or vinyl acetate, and the circular flat discs attached by heat-sealing to the rod ends are made of spunbonded non- "obtained by autololating high density polyethylene extruded filaments of 200 g / 10 min at 160 ° C and 2.16 kg or by a 40% hexylmaleate ethylene copolymer having a fluidity index of between 15 and 30 g / 10 min. (At 160 degrees C and 2.16 kg).
