Abstract
Description
Bewehrungsteil für zementöse Knochenfüllungen Reinforcement part for cementitious bone fillings
oder -ansätze und zugehöriger Knochenzement Die Erfindung bezieht sich auf ein Bewehrungsteil für zementöse Knochenfüllungen oder -ansätze mit. ugeordneter Knochenzementmasse, welches als einem weichelastischen, z.urecht.-schneidbaren Schwamm aus körperverträglichem Material mit Kanaldurchmessern bis zu eirIigen Mi ;iimetern und aus einer dem Schwamm zugeordneten, für dessen durchgehende Tränkung ausreichend dünnflüssige Knochenzement- oder sonstige schnellhärtende Kunststoffmasse besteht, gemäß Patentanmeldung P 30 38 319.8. or approaches and associated bone cement The invention relates on a reinforcement part for cementitious bone fillings or attachments with. more orderly Bone cement mass, which is a soft, elastic, cuttable sponge Made of body-compatible material with canal diameters of up to egg-shaped micrometers and from one assigned to the sponge, sufficient for its continuous impregnation consists of thin-bodied bone cement or other fast-hardening synthetic material, according to patent application P 30 38 319.8.
In der Hauptanmeldung sind bereits eine Reihe von Wegen aufgezeigt, wie ein als Bewehrungsteil verwendbarer Schwamm hergestellt werden kann.The main application already shows a number of ways how a sponge that can be used as a reinforcement part can be produced.
Der vorliegenden Zusatzanmeldung liegt die Aufgabe zugrunde weitere Möglichkeiten zur Schaffung eines geeigneten, schwammartigen Bewehrungsteiles aufzuzeigen.The present additional application is based on the task of others Show possibilities for creating a suitable, spongy reinforcement part.
In Weiterbildung der Lehre der Hauptpatentanmeldung ist erfindungsgemäß vorgesehen, daß als Schwamm ein aus körperverträglichem Fadenmaterial hergestelltes Fadengebilde vorgesehen wird. Die Herstellung des Schwammes als Fadengebilde bietet den Vorteil, daß nunmehr durch Wahl des Fadenmateriales, der Fadenstärke und der Fadenverschlingungsart eine Vielzahl von Ausführungsformen ermöglicht werden, mit denen eine Anpassung an die bei den einzelnen chirurgischen Angriffen oft sehr unterschiedlichen Anforderungen preiswert vorgenommen werden kann. So kann der Erfindung zufolge das Fadengebilde aus resorbierbaren oder nichtresorbierbaren Fäden oder aus einem Gemisch dieser Fäden bestehen, wobei vorzugsweise das Fadengebilde teilweise oder vollständig aus kordel groben Fäden von bis zu einigen Millimetern Durchmesser besteht. Ijei der Tränkung eines solchen Fadengeb ii des mit ausreichend dünnfltissiger Knochenzementmasse bleiben nach dem Abtropfen der Zementmasse aufgrund der groben Struktur des Fadengebildes randoffene Poren, in die das Knochenmaterial oder auch - wenn gewünscht - Weichteile mit der Zeit einsprießen und eine gute auch formschlüssige Verankerung zwischen Knochen und Prothese gewährleisten bzw.In a further development of the teaching of the main patent application is according to the invention provided that a sponge made from a biocompatible thread material Thread structure is provided. The manufacture of the sponge as a thread structure offers the advantage that now by choosing the thread material, the thread thickness and the Fadenverschlingungsart a variety of embodiments are made possible with which an adaptation to the often very different in the individual surgical attacks Requirements can be made inexpensively. According to the invention, this can be done Thread structure made of absorbable or non-absorbable threads or a mixture these threads exist, preferably the thread structure partially or completely Consists of coarse cords up to a few millimeters in diameter. Ijei the impregnation of such a thread package with a sufficiently thin-bodied bone cement compound remain after the cement paste has dripped off due to the coarse structure of the thread structure Open-edged pores into which the bone material or - if desired - soft tissue Inject over time and a good, also form-fitting anchoring between Ensure bones and prosthesis or
Verbindung mit den Weichteilen herstellen. Die resorbierbaren Fäden werden dabei mit der Zeit von Körperflüssigkeit aufgelöst, und in die frei gewordenen Räume wächst ebenfalls Knochenmaterial allmählich nach.Establish connection with the soft tissues. The absorbable threads will dissolved in the course of time by body fluid, and in the vacated spaces also gradually grow back bone material.
Für erfindungsgemäße Zwecke sind Fäden aus organischen Sehnen, Därmen, Operationsfäden aus Katgut oder auch aus synthetischem Material geeignet.For purposes according to the invention, threads from organic tendons, intestines, Surgical threads made of catgut or synthetic material are suitable.
Zweckmäßigerweise wird das Bewehrungsteil als ebene Bahn, Block, Schlauch, Strang oder Paßstück vorgefertigt.The reinforcement part is expediently as a flat sheet, block, hose, Prefabricated strand or adapter.
Die Erfindung wird im folgenden anhand für Zeichnung nlther erlautert, in der @@ Fig. 1 ein Bewehrungsteil in Form einer einlagig gewebten dünnen Bahn aus Schußfäden 1 und Kettfäden 2, die hier gleichen Durchmesser aufweisen, der zweckmäßigerweise zwischen 0,5 bis 1,5 mm liegt. Ein solches bahnartiges Bewehrungsmaterial ist insbesondere zur Schienung otler Bandagierung eines Kiiochenbruches geeignet. Nach Tränken mit einer Knochenzementmasse wird es in der in der Hauptanmeldung gezeigten Weise um eine Knochenbruchstelle gewickelt, wobei es nach Aushärten der Zementmasse sofort die Knochenbruchstücke fixiert. Durch Einsprießen von Knochenmaterial in Gewebezwischenräume wird eine dauerhafte Verbindung und Verankerung gewährleis.The invention is explained in more detail below with reference to the drawing, in the @@ Fig. 1 a reinforcement part in the form of a single-layer woven thin web from weft threads 1 and warp threads 2, which have the same diameter here, which is expediently is between 0.5 to 1.5 mm. Such a sheet-like reinforcement material is in particular suitable for splinting otler bandaging of a broken jaw. After soaking with a bone cement compound is used in the manner shown in the parent application wound a bone fracture, whereby it immediately after hardening of the cement paste the bone fragments fixed. By injecting bone material into the spaces between the tissues a permanent connection and anchoring is guaranteed.
Fig. 2 zeigt ein blockartiges Fadengebilde aus vielen übereinander liegenden und miteinander verwebten, verflochtenen Fäden, das der Operateur auf die jeweils benötigte Form zurechtschneiden kann. Bei diesem Ausführungsbeispiel sind millimeterdicke resorbierbare Fäden 3 mit diinnen, nichtresorbierbaren Fäden 4 gemischt. Fig. 2 shows a block-like thread structure made up of many on top of one another lying and interwoven, intertwined threads that the surgeon picks up can cut the required shape. In this embodiment are millimeter-thick absorbable threads 3 with thin, non-absorbable threads 4 mixed.
Fig. 3 zeigt ein schlauchartig ausgebildetes, mehrlagiges Fadengebilde aiis Längs fäden 5 und Querfäden 6. Fig. 3 shows a hose-like, multi-layer thread structure aiis longitudinal threads 5 and transverse threads 6.
Fig. 4 zeigt ein strangrörmiges Fadengebilde aus wiederum dicken, resorbierbaren Fäden 7 und dünnen, nichtresorbierbaren Fäden 8, die miteinander verflochten sind. Fig. 4 shows a strand-like thread structure from again thick, absorbable sutures 7 and thin, non-absorbable sutures 8, which are connected to one another are intertwined.
