Abstract

The implant comprises a cage made from carbon fibre-reinforced PEEK and provided with titanium rods (3) at each end and with trapezoidal teeth (2) and fixing holes (5). A medical implant used in cervical surgery for replacing a vertebra comprises a cage made from a carbon fibre-reinforced polyether-etherketone (PEEK) composite. The proximal and distal ends of the cage have trapezoidal teeth for anchoring in the adjacent vertebrae. A titanium rod is provided at each end of the implant so that it can be seen in x-rays. The cage has a hollow structure (4) and contains holes for fixing parts. The length of the cage corresponds to the length of the removed vertebra.

   Beschriiving 
RAAM VOOR   WERVELLICHAAM   VERVANGING IN POLYETHERETERKETON. 



  De Ti-PEEK   CORPUSREPLACEMENT   cage is een medisch implantaat voor gebruik in cervikale chirurgie (1). Het implantaat bestaat uit een composiet materiaal waarvan de componenten enerzijds een polyether-etherketon matrix en anderzijds een carbonvezelversterking zijn. De elasticitaits modulus van de Ti-PEEK   CORPUSREPLACEMENT   cage is nagenoeg gelijk aan deze van cortikaal bot. 



  Het implantaat heeft een proximaal en distaal kontakteindvlak dat bezet is met trapezoïdale uitsteeksels (2) die zich als tanden vastzetten in de aanliggende wervellichamen Het Ti-PEEK   CORPUSREPLACEMENT   implantaat is radiolucent. Teneinde het RX visualiseerbaar te maken, bevat het een Titaniumstaafje (3) op ieder uiteinde. Het Ti-PEEK CORPUSREPLACEMENT implantaat heeft een holle (4) struktuur en fixeergaten (5) voor bevestiging. 



  De lengte van het implantaat stemt overeen met de lengte (6) van het stuk weggenomen wervelzuil.

   Description
WINDOW FOR WORK BODY REPLACEMENT IN POLYETHERETER KETONE.



  The Ti-PEEK CORPUS REPLACEMENT cage is a medical implant for use in cervical surgery (1). 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 the Ti-PEEK CORPUS REPLACEMENT cage 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 (2) that attach to the adjacent vertebral bodies like teeth. The Ti-PEEK CORPUS REPLACEMENT implant is radiolucent. In order to make the RX visible, it contains a Titanium rod (3) on each end. The Ti-PEEK CORPUS REPLACEMENT implant has a hollow (4) structure and fixing holes (5) for attachment.



  The length of the implant corresponds to the length (6) of the vertebral column removed.

Conclusies @ 1,- De Ti-PEEK CORPUSREPLACEMENT cage bewerkstelligt op veilige, doeltreffende en betrouwbare wijze de primaire stabiliteit en integriteit van de voorste kolom van de cervikale wervelzuil in de eerste dagen van herstel na corporectomie.  Conclusions @ 1, - The Ti-PEEK CORPUS REPLACEMENT cage ensures the primary stability and integrity of the anterior column of the cervical vertebral column in the first days of recovery after corporectomy in a safe, effective and reliable way. 2, - De Ti-PEEK CORPUSREPLACEMENT cage vormt een stut die de lokaal resterende delen van de cervikale wervelzuil bewaart onder gedistraheerde en gerestaureerde discushoogte(n) 3.- De Ti-PEEK CORPUSREPLACEMENT cage houdt de decompressie in stand 4. - Gebruik van een Ti-PEEK CORPUSREPLACEMENT cage maakt de noodzaak voor een tweede operatiesite voor boneharvesting overbodig. 2, - The Ti-PEEK CORPUS REPLACEMENT cage forms a prop that preserves the locally remaining parts of the cervical vertebral column under distilled and restored disc height (s) 3.- The Ti-PEEK CORPUS REPLACEMENT cage maintains decompression 4. - Use of a Ti-PEEK CORPUS REPLACEMENT cage eliminates the need for a second bone harvesting surgical site. 5. - De holle strukttur van de Ti-PEEK CORPUSREPLACEMENT bezorgt een mechanisch sterke holle struktuur waarin graftmeteriaal kan geplaatst worden dat de aanzet zal worden voor in- en doorgroei. 5. - The hollow structure of the Ti-PEEK CORPUS REPLACEMENT provides a mechanically strong hollow structure in which graft meter can be placed that will be the starting point for growth and further growth. 6. - Deze uitvinding beperkt zich niet to PEEK als grondsubstraat, maar eveneens ieder materiaal dat de biochemisch en mechanisch dezelfde of betere eigenschappen vertoont. 6. This invention is not limited to PEEK as a substrate, but also to any material that exhibits the same or better biochemically and mechanically properties. 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.
