Description
Die Erfindung betrifft 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 elastisch biegbar ist.The invention relates to a strip-shaped implant with transversely extending to its longitudinal direction transverse slots, which are each open to one of the two side edges of the strip-shaped implant, such that the strip-shaped implant in the strip plane is at least in a partial ring shape elastically bendable.
Ein derartiges streifenförmiges Implantat ist beispielsweise durch die
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. 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. 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.In a brain operation, parts of the skull are milled out and removed. In the reimplantation, therefore, a milling gap is formed between the skull and the milled out skull part, which for cosmetic reasons, for example, is filled with bone cement or covered with titanium wire nets. Bone cement is provided as a bicomponent material that is mixed together just prior to introduction into the milling slot. There is only a limited amount of time available for processing the bone cement, since the hardening process of the bone cement begins immediately after the components mix together and progresses rapidly. The titanium wire net later prevents a collapse of the scalp. Before implanting, the titanium wire mesh must be cut to the appropriate size and adapted to the profile of the milling gap. For this additional instruments are needed.

Demgegenüber ist es die Aufgabe der vorliegenden Erfindung, bei einem streifenförmigen Implantat der eingangs genannten Art eine einfache Längenanpassung des Implantats ohne Verwendung zusätzlicher Werkzeuge zu ermöglichen.In contrast, it is the object of the present invention to allow a strip-shaped implant of the type mentioned a simple length adjustment of the implant without the use of additional tools.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass Stege, welche die Querschlitze definieren, Sollbruchstellen aufweisen.This object is achieved in that webs which define the transverse slots have predetermined breaking points.
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 be adapted to the course of the milling gap due to its high bending flexibility. 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.More preferably, the transverse slots are alternately open to one and the other side edge so as to maximize bending 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 from the side edge at least to the middle of the strip-shaped implant. The longer the slots, the higher the bending flexibility of the strip-shaped implant.
Bei besonders bevorzugten Ausführungsformen der Erfindung sind zumindest einige der Querschlitze an ihrem geschlossenen Ende, insbesondere gabelförmig, verbreitert und weisen eine Befestigungsöffnung auf, durch die hindurch ein Befestigungsstift gesteckt werden kann.In particularly preferred embodiments of the invention, at least some of the transverse slots at its closed end, in particular fork-shaped widened and have a mounting opening, through which a fastening pin can be inserted.
Zusätzlich können an den beiden Längsenden des streifenförmigen Implantats oder auch dazwischen Befestigungs- bzw. Zwischenplättchen mit Befestigungsöffnungen vorhanden 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.In addition, at the two longitudinal ends of the strip-shaped implant or between them, there may be attachment plates or intermediate plates with attachment openings in order to allow the attachment of the strip-shaped implant by means of fastening means on the cranial bone. In particular, the platelets protrude laterally beyond the side edges and can also each have a fastening opening at the protruding ends, so as to also enable attachment of the strip-shaped implant directly to the cranial bone or to the milled-out skullcap part.
Bei vorteilhaften Ausführungsformen der Erfindung ist das streifenförmige Implantat aus einem Draht gebogen oder aus einem Blechteil gefertigt.In advantageous embodiments of the invention, the strip-shaped implant is bent from a wire or made from a sheet metal part.
Weitere Vorteile der Erfindung ergeben sich aus der Beschreibung und der Zeichnung. 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 drawings. The embodiments shown and described are not to be understood as exhaustive enumeration, but rather have exemplary character for the description of the invention.
