Abstract
Przedmiotem wynalazku jest śruba interferencyjna obejmująca korpus śruby zawierający część wierzchołkową (1) posiadającą powierzchnię czołową (2), pomiędzy częścią wierzchołkową a częścią końcową zasadniczy korpus śruby z umieszczonym na powierzchni zewnętrznej gwintem śruby oraz część końcową (3) posiadającą powierzchnię tylną (4). Ponadto wzdłuż osi korpusu śruby jest kanał wewnętrzny (5) a pomiędzy występami gwintu (6), w bruzdach gwintu (7), usytuowane są otwory przelotowe łączące się z wewnętrznym kanałem. Rozwiązanie charakteryzuje się tym, że posiada - kanał wewnętrzny (5) usytuowany jest pomiędzy powierzchnią czołową (2) części wierzchołkowej (1) a powierzchnią tylną (4) części końcowej (3) i na swojej długości zmienia swoją wielkość oraz kształt przekroju, przy czym kanał wewnętrzny (5) w części wierzchołkowej (1) śruby jest o przekroju koła zaś kanał wewnętrzny w zasadniczej części korpusu śruby jest o przekroju wielokąta, - w zasadniczej części korpusu otwory przelotowe śruby, umieszczone w ściance zasadniczego korpusu śruby, mają powtarzalny kształt, - gwint umieszczony na powierzchni zewnętrznej zasadniczej części śruby jest gwintem tępym interferencyjnym, którego zadaniem jest dociskanie implantów do kości bez ich uszkadzania, - chropowatość powierzchni zewnętrznej śruby jest w zakresie od 25 do 35 µm, a porowatość powierzchni zewnętrznej śruby jest w zakresie od 0,01 mm do 2 mm, - pokryta jest materiałami biokompatybilnymi i bakteriobójczymi. Innym rozwiązaniem według wynalazku jest sposób wytwarzania śruby interferencyjnej.
