Abstract

The implant has a hollow structure (4) and is made from a carbon fibre-reinforced PEEK composite and has teeth (3) protruding from its proximal and distal faces for anchoring it in the adjacent vertebral bodies. A lumbar stabilizing frame used as an implant for back surgery is made from a composite material comprising a polyether-ether ketone (PEEK) matrix reinforced with carbon fibres. The implant has proximal and distal faces with trapezoidal protrusions which act as teeth for anchoring the implant in the adjacent vertebra bodies. The implant contains three titanium pins (2) so that it is visible under x-rays. The implant has a hollow structure. The end surfaces (6) are anatomically shaped.

   <Desc/Clms Page number 1>      Beschrijving     L UMBAAL   POSTERIEUR   IMPA CTEERBAAR   STABILISA TIE RAAM Het LUMBAAL POSTERIEUR IMPACTEERBAAR STABILISATIE RAAM is een medisch implantaat vooi gebruik in rugchirurgie . Het implantaat bestaat uit een composiet materiaal waarvan de componenten enerzijds een polyether-etherketon matrix en anderzijds een carbonvezelversterking zijn. De elasticitaits modulus van dit implataat is nagenoeg gelijk aan deze van cortikaal bot.    Het implantaat heeft een proximaal en distaal kontakteindvlak dat bezet is met trapezoïdale uitsteeksels (3) die zich als tanden vastzetten in de aanliggende wervellichamen Het implantaat is radiolucent. Teneinde het RX visualiseerbaar te maken, bevat het drie Titaniumstaafjes (2).    Het implantaat heeft een holle struktuur (4) om doorgroei mogelijk te maken.    De afmetingen van het implantaat stemmen overeen met de opgehoogde afmetingen van de geëvacueerde discus. Aan de voorzijde heeft Het LUMBAAL POSTERIEURIMPACTEERBAAR STABILISATIE RAAM een zelfdistraherende helling ( 1) om de opening aan posterieure zijde te vergroten tijdens de impactfaze. De boven- en onder eindvlakken hebben een anatomische vorm (6). zie tekening (1) zelfdistraherende helling (2) Titanium merkeerstifts (3) toppen (4) centraal gat (5) beschermende afronding (6) eindplaat contact met anatomische vorm (7) Fixatiegat voor i nstrument (8) breedte (9) hoogte (10) lengte   <Desc / Clms Page number 1>     Description L UMBAL POSTERIOR IMPA CERTIBLE STABILIZATION WINDOWThe LUMBAR POSTERIOR IMPACTABLE STABILIZATION WINDOW is a medical implant for use in back surgery. The implant consists of a composite material whose components are on the one hand a polyether-ether ketone matrix and on the other hand a carbon fiber reinforcement. The elasticitaits modulus of this implant is almost the same as that of cortical bone.   The implant has a proximal and distal contact end face that is covered with trapezoidal protrusions (3) that attach to the adjacent vertebral bodies like teeth. The implant is radiolucent. In order to make the RX visible, it contains three Titanium rods (2).   The implant has a hollow structure (4) to allow further growth.   The dimensions of the implant correspond to the increased dimensions of the evacuated disc. On the front it has LUMBAAL POSTERIORIMPACTABLE STABILIZATION WINDOW A self-distorting slope (1) to enlarge the aperture on the posterior side during the impact phase. The upper and lower end faces have an anatomical shape (6). see drawing (1) self-distorting slope (2) Titanium marker pens (3) tops (4) central hole (5) protective rounding (6) end plate contact with anatomical shape (7) Fixation hole for instrument (8) width (9) height (9) 10) length

Conclusies l,- Het LUMBAAL POSTERIEUR IMPACTEERBAAR STABILISATIE RAAM bewerkstelligt op veilige, doeltreffende en betrouwbare wijze de primaire stabiliteit na discus evacuatie 2, - Het LUMBAAL POSTERIEUR IMPACTEERBAAR STABILISATIE RAAM vormt een stut die de gerestaureerde interdiscale hoogte in stand houdt.. Conclusions 1 - The LUMBAR POSTERIOR IMPACTABLE STABILIZATION WINDOW ensures primary stability after discus evacuation in a safe, effective and reliable manner 2, - The LUMBAR POSTERIOR IMPACTABLE STABILIZATION WINDOW forms a prop that maintains the restored interdiscal height. 3.- Het LUMBAAL POSTERIEUR IMPACTEERBAAR STABILISATIE RAAM houdt de decompressie in stand 4.- Gebruik van een LUMBAAL POSTERIEUR IMPACTEERBAAR STABILISATIE RAAM maakt de noodzaak voor een tweede operatiesite voor boneharvesting overbodig. 3.- The LUMBAR POSTERIOR IMPACTABLE STABILIZATION WINDOW maintains decompression.5 - De holle strukttur van Het LUMBAAL POSTERIEUR IMPACTEERBAAR STABILISATIE RAAM bezorgt een mechanisch sterke holle struktuur waarin eventueel graftmeteriaal kan geplaatst worden dat de aanzet zal worden voor in- en doorgroei 6.- Deze uitvinding beperkt zich niet to PEEK als grondsubstraat, maar eveneens ieder materiaal dat de biochemisch en mechanisch dezelfde of betere eigenschappen vertoont.5 - The hollow structure of The LUMBAR POSTERIOR IMPACTABLE STABILIZATION WINDOW provides a mechanically strong hollow structure in which possibly graftmeterial can be placed that will be the starting point for ingrowth and growth 6.- This invention is not limited to PEEK as soil substrate, but also any material that exhibits the same or better properties in biochemically and mechanically.7. - Deze uitvinding is ook van toepassing voor lichte geometrische eigenschappen van het ruw oppervlak, van de buiten- en binnendimensies en van de plaats en de grootte van de fixeergaten.7. This invention also applies to light geometric properties of the rough surface, of the outer and inner dimensions and of the location and size of the fixing holes.
