Abstract

The articles are made from non-metallic materials e.g. flint, diamond, bone, horn, antler, teeth, dental enamel, ivory and/or dental composite material.

Description

Vervaardiging van gebruiksvoorwerpen en medische instrumenten uit nieuwe alternatieve materialen waardoor deze kunnen worden gebruikt binnen een magnetisch veld tijdens S interventies of beeldvorming met behulp van Magnetische Resonance Imaging (zogenaamde MRI-scan).Manufacture of utensils and medical instruments from new alternative materials that allow them to be used within a magnetic field during S interventions or imaging using Magnetic Resonance Imaging (so-called MRI scan).

Uit metaal vervaardigde voorwerpen geven bij beeldvorming met behulp van magnetische resonantie (zogenaamde MRI-scanning) uitgebreide artefacten of kunnen door de door 10 magnetisme veroorzaakte verplaatsingen niet zonder gevaar worden gebruikt.Objects made of metal produce extensive artifacts during magnetic resonance imaging (so-called MRI scanning) or cannot be used without danger due to the movements caused by magnetism.

De uitvinding heeft betrekking op alle instrumenten of gebruiksvoorwerpen die dankzij vervaardiging uit andere dan bijvoorbeeld veelal uit metaal vervaardigde materialen ook te gebruiken zijn binnen een magnetisch veld of MRI-scanner zonder dat er al te grote verstoring van beeldvorming plaatsvindt door zogenaamde susceptibiliteits-artefacten of verplaatsing 1S optreedt van voorwerpen waardoor gevaar voor de patiënt of functionaliteit van de apparatuur zouden kunnen ontstaan.The invention relates to all instruments or articles of use which can also be used within a magnetic field or MRI scanner thanks to manufacture from materials other than metal-made materials, for example, without excessive distortion of imaging occurring through so-called susceptibility artifacts or displacement 1S Occurrence of objects that could cause danger to the patient or functionality of the equipment.

Door gebruik van deze materialen kunnen de voorwerpen ook op kwalitatief hoogwaardige wijze binnen een magneetveld worden ingezet en zullen zij een hoogwaardiger alternatief zijn voor 20 reeds andere bestaande alternatieve materialen zoals bijvoorbeeld porcelein.By using these materials, the articles can also be used in a high-quality manner within a magnetic field and they will be a higher-quality alternative to already existing alternative materials such as, for example, porcelain.

De hier voor het eerst voorgestelde alternatieve materialen voor gebruik in een magnetisch veld of MRI-scanner zijn elk willekeurig gesteente, zoals bijvoorbeeld vuursteen (silex) en diamant, bot of been, hoorn, gewei alsook tand, tandbeen, tandglazuur, ivoor alsook alle bekende 25 tandheelkundig gebruikte composietmaterialen of combinaties hiervan. Voordeel van deze materialen is dat ze veelal door bewerking voldoende scherp gemaakt kunnen worden om te kunnen gebruiken voor interventies in het (menselijk) lichaam, (snijden, prikken of weefsel verwijderen) alsook zeer sterk zijn zodat ze ook voor al dan niet tijdelijke implantaties of fixaties kunnen worden gebruikt.The alternative materials for use in a magnetic field or MRI scanner presented here for the first time are any rock, such as flint (silex) and diamond, bone or bone, horn, antlers as well as tooth, dental bone, dental enamel, ivory and all known 25 dentically used composite materials or combinations thereof The advantage of these materials is that they can often be made sufficiently sharp by processing to be able to be used for interventions in the (human) body, (cutting, pricking or removing tissue) and are also very strong so that they can also be used for temporary or non-temporary implantations or fixations can be used.

Deze materialen kunnen worden gebruikt voor (medische) (gebruiks-) voorwerpen die bijvoorbeeld tijdens operaties of andere interventies in het menselijk lichaam worden ingezet.These materials can be used for (medical) (consumer) objects that are used in the human body during operations or other interventions, for example.

f1021608 2 5 Hierbij valt te denken aan bijvoorbeeld (hecht)naalden, messen of scalpels, (operatie)tangen, (operatie) klemmen, biopsie-naalden, (hoofd)steunen, scharen, tafels, schroevedraaiers, schroeven, bouten, hamers, beitels, boren, in of uitwendige fixatie-materialen (voor bijvoorbeeld botbreuken), brancards, (infuus)standaards en ander, eventueel nog te ontwerpen instrumentarium. Slijpen, aanscherpen of anderszins kan ondermeer geschieden met niet-10 metalen gereedschap teneinde metaalresten op het oppervlakte en daarmee zogenaamde susceptibiliteitsartefacten op de afbeeldingen te voorkomen.f1021608 2 5 This includes, for example, (stitched) needles, knives or scalpels, (surgical) pliers, (surgical) clamps, biopsy needles, (head) supports, scissors, tables, screwdrivers, screws, bolts, hammers, chisels , drilling, in or external fixation materials (for bone fractures, for example), stretchers, (infusion) standards and other, possibly still to be designed, instruments. Grinding, sharpening or otherwise can be done with non-metal tools, among other things, in order to prevent metal residues on the surface and thus so-called susceptibility artifacts on the images.

Dankzij vervaardiging van genoemde gebruiksvoorwerpen uit voorgestelde alternatieve materialen kunnen bepaalde handelingen ook binnen een magneetveld of magnetische 1S resonantie veld worden verricht, zodat dit niet meer onder doorlichting van röntgenstraling (met een klein risico op schadelijke bijwerkingen op lange termijn) hoeft te gebeuren zoals tot nu toe voor veel handelingen gebruikelijk.Thanks to the manufacture of the aforementioned utensils from proposed alternative materials, certain actions can also be carried out within a magnetic field or magnetic 1S resonance field, so that this no longer has to be done under the X-ray screen (with a small risk of harmful side effects in the long term) such as until now common for many actions.
