Description

DESCRIZIONE DESCRIPTION

Nel campo ortopedico chirurgico sono ormai usati molti tipi di placche per osteosintesi prodotte con leghe di titanio, acciaio od altri metalli. In alcune patologìe gravi dell’osso come in oncologia o nelle ostiomeliti infettive, l’utilizzo di questi materiali non aiuta la asepsia. In the orthopedic surgical field, many types of osteosynthesis plates produced with titanium alloys, steel or other metals are now used. In some serious bone pathologies such as in oncology or infectious osteomyelitis, the use of these materials does not help asepsia.

Il poter realizzare diverse placche in carbonio e di argento potrebbe fornire una valida alternativa ed un concreto aiuto alla asepsia. Being able to make different carbon and silver plates could provide a valid alternative and a concrete help to asepsia.

L’argento è un materiale pregiato ed ha la capacità di rilasciare degli ioni che aiutano alla detersione dei vari tessuti. L’unico problema è che l’argento da solo non è in grado di sostenere un grande peso perché tende a deformarsi con le varie _ sollecitazioni. La placca qui proposta (figura 1) è fatta con il carbonio coperto da resine epossidiche che sono biologicamente compatibili. Su ogni superficie della barra che andrà a contatto diretto con l’osso, sono stati posizionati dei fogli d’argento. Il carbonio è stato lavorato su diverse direzioni in modo da fornire la massima resistenza sia nel carico che nelle torsioni e varie sollecitazioni. Silver is a valuable material and has the ability to release ions that help cleanse the various fabrics. The only problem is that silver alone is not able to support a great weight because it tends to deform with various _ stresses. The plate proposed here (figure 1) is made with carbon covered by epoxy resins which are biologically compatible. Silver sheets have been placed on each surface of the bar that will come into direct contact with the bone. The carbon has been worked in different directions in order to provide maximum resistance both in the load and in the twists and various stresses.

La placca è fornita di diversi fori dove poter inserire le viti. Ogni vite avrà un sistema di auto bloccaggio sulla placca, inoltre ogni foro è rivestito in argento. The plate is provided with several holes where you can insert the screws. Each screw will have a self-locking system on the plate, and each hole is silver coated.

Sulla placca all’altezza di ogni foro ci sono dei piccoli rialzi e solo sul lato che poggia sull’osso. Questi piccoli piedini di circa due millimetri sono in argento e consentono un lieve distanza della placca dall’osso. On the plate at the height of each hole there are small rises and only on the side that rests on the bone. These small feet of about two millimeters are made of silver and allow a slight distance between the plate and the bone.

RIVENDICAZIONI Placca per osteosintesi fata di carbonio ed argento. Nella figura 1 è rappresentata: - una placca che è composta in tessuto di carbonio lavorato nei vari strati su tute le direzioni. - E’ usata una resina epossidica per ricoprire e fermare il tessuto di carbonio in modo tale che non possa sfiletarsi ed anzi resistere a qualsiasi forza. Nella figura 1 al punto 1 è indicato il carbonio rivestito di resina ipossidica. Al punto 2 è indicato il foglio di argento che ricopre solo di un lato la placca di carbonio. - Nel punto 3 sono rappresentati i fori con la filetatura in argento per l’auto bloccaggio delle viti sulla placca. - Nel punto 4 sullo stesso lato del foglio d’argento, è rappresentata la parte finale dei fori con un rialzo sporgente di circa 2 mm.CLAIMS Fairy plate for osteosynthesis of carbon and silver. Figure 1 shows: - a plate that is made of carbon fabric worked in the various layers on all directions. - An epoxy resin is used to cover and stop the carbon fabric so that it cannot slip off and indeed resist any force. In figure 1 at point 1 the carbon coated with epoxy resin is indicated. Point 2 indicates the silver sheet that covers the carbon plate on one side only. - Point 3 shows the holes with silver thread for self-locking the screws on the plate. - In point 4 on the same side of the silver sheet, the final part of the holes is represented with a protruding rise of about 2 mm.
