Abstract
Description
Die Erfindung betrifft ein streifenförmiges Implantat, welches insbesondere bei Gehirnoperationen zur Abdeckung eines in der Schädeldecke vorhandenen Frässpalts eingesetzt wird.The The invention relates to a strip-shaped Implant, which in particular during brain surgery to cover one in the skullcap existing milling gap is used.
Bei einer Gehirnoperation werden Teile der Schädeldecke herausgefräst und entnommen. Bei der Reimplantierung bildet sich daher zwischen der Schädeldecke und dem herausgefrästen Schädeldeckenteil ein Frässpalt aus, der aus kosmetischen Gründen beispielsweise mittels Knochenzement aufgefüllt oder mit Titandrahtnetzen abgedeckt wird.at brain surgery, parts of the skull are milled out and removed. In the reimplantation therefore forms between the skullcap and milled out Skulls part a milling gap out, for cosmetic reasons filled for example by means of bone cement or with titanium wire nets is covered.
Knochenzement wird als Zweikomponentenmaterial bereitgestellt, das kurz vor der Einbringung in den Frässpalt zusammengemischt wird. Für die Verarbeitung des Knochenzements steht nur eine begrenzte Zeitspanne zur Verfügung, da der Aushärtevorgang des Knochenzements unmittelbar nach dem Zusammenmischen der Komponenten beginnt und zügig voranschreitet.bone cement is provided as a two-component material just before the Introduction into the milling gap is mixed together. For the processing of the bone cement is only a limited period of time to disposal, since the curing process of the bone cement immediately after mixing the components together starts and quickly progresses.
Das Titandrahtnetz verhindert später ein Einfallen der Kopfhaut. Vor dem Implantieren muss das Titandrahtnetz auf die jeweilige Größe zugeschnitten und an den Verlauf des Frässpalts angepasst werden. Hierzu werden zusätzliche Instrumente benötigt.The Titanium wire net prevents later a collapse of the scalp. Before implanting, the titanium wire mesh tailored to the size and on the course of the milling gap be adjusted. For this additional instruments are needed.
Demgegenüber ist es die Aufgabe der vorliegenden Erfindung, das Abdecken des Frässpalts zu vereinfachen.In contrast, is it is the object of the present invention to cover the milling gap to simplify.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein streifenförmiges Implantat mit quer zu seiner Längsrichtung verlaufenden Querschlitzen, die jeweils zu einem der beiden Seitenränder des streifenförmigen Implantats hin offen sind, derart, dass das streifenförmige Implantat in der Streifenebene mindestens in eine Teilringform, insbesondere in eine geschlossene Ringform, elastisch biegbar ist.These The object is achieved by a strip-shaped Implant with transverse to its longitudinal direction extending transverse slots, each to one of the two side edges of stripe Implantats are open, such that the strip-shaped implant in the strip plane at least in a partial ring shape, in particular in a closed ring shape, is elastically bendable.
Das erfindungsgemäße streifenförmige Implantat kann aufgrund seiner hohen Biege-Flexibilität an den Verlauf des Frässpalts angepasst werden. Hierzu ist kein zusätzliches Werkzeug notwendig.The Strip-shaped implant according to the invention Can due to its high bending flexibility to the course of the milling gap be adjusted. No additional tools are necessary for this.
Besonders bevorzugt sind die Querschlitze abwechselnd zu dem einen und zu dem anderen Seitenrand hin offen, um so die Biege-Flexibilität zu maximieren.Especially Preferably, the transverse slots are alternately to the one and to open to the other side edge so as to maximize flexing flexibility.
Vorzugsweise erstrecken sich die Schlitze ausgehend vom Seitenrand mindestens bis zu der Mitte des streifenförmigen Implantats. Je länger die Schlitze, desto höher ist die Biege-Flexibilität des streifenförmigen Implantats.Preferably the slots extend at least starting from the side edge up to the middle of the strip-shaped Implant. The longer the slots, the higher is the bending flexibility of the strip-shaped Implant.
Bei besonders bevorzugten Ausführungsformen der Erfindung sind zumindest einige der Querschlitzen an ihrem geschlossenen Ende, insbesondere gabelförmig, verbreitert und weisen eine Befestigungsöffnung auf, durch die hindurch ein Befestigungsstift gesteckt werden kann.at particularly preferred embodiments at least some of the transverse slots are at their closed End, in particular bifurcated, widened and have a mounting hole through which a fastening pin can be inserted.
Alternativ oder zusätzlich können an den beiden Streifenenden oder auch dazwischen Befestigungs- bzw. Zwischenplättchen mit Befestigungsöffnungen vorgesehen sein, um die Befestigung des streifenförmigen Implantats mittels Befestigungsmitteln am Schädelknochen zu ermöglichen. Die Plättchen ragen insbesondere seitlich über die Seitenränder hinaus und können auch an den hinausragenden Enden jeweils eine Befestigungsöffnung aufweisen, um so auch eine Befestigung des streifenförmigen Implantats direkt am Schädelknochen bzw. an dem herausgefrästen Schädeldeckenteil zu ermöglichen.alternative or additionally can at the two end of the strip or between them fastening or between platelets with mounting holes be provided to the attachment of the strip-shaped implant to allow by means of fasteners on the skull bone. The tiles especially protrude laterally over the margins out and can also have at the protruding ends each have a mounting opening to as well as an attachment of the strip-shaped implant directly on skull bones or at the milled Skulls part to enable.
Vorteilhaft weisen die die Querschlitze definierenden Stege, insbesondere im Übergangsbereich zwischen zwei Stegen, Sollbruchstellen auf, die eine einfache Längenanpassung des Implantats an den Verlauf des Frässpalts ohne Verwendung zusätzlicher Werkzeuge ermöglichen.Advantageous have the webs defining the transverse slots, in particular in the transition region between two webs, predetermined breaking points, which is a simple length adjustment of the implant to the course of the milling gap without the use of additional Enable tools.
Bei vorteilhaften Ausführungsformen der Erfindung ist das streifenförmige Implantat aus einem Draht gebogen oder aus einem Blechteil gefertigt.at advantageous embodiments The invention is the strip-shaped Implant bent from a wire or made from a sheet metal part.
Weitere Vorteile der Erfindung ergeben sich aus der Beschreibung und der Zeichnung. Ebenso können die vorstehend genannten und die noch weiter ausgeführten Merkmale erfindungsgemäß jeweils einzeln, für sich oder zu mehreren in beliebigen Kombinationen Verwendung finden. Die gezeigten und beschriebenen Ausführungsformen sind nicht als abschließende Aufzählung zu verstehen, sondern haben vielmehr beispielhaften Charakter für die Schilderung der Erfindung.Further Advantages of the invention will become apparent from the description and the Drawing. Likewise the above-mentioned and still further features according to the invention individually, for themselves or to several in any combination use. The embodiments shown and described are not as final enumeration but rather have exemplary character for the description the invention.
