Abstract
Description
Die Erfindung betrifft eine Tamponade zur resorbierbaren, volu menaktiven Wundhöhlenprotektion, vorzugsweise aus mit einem Poly urethan-Strukturweichschaum-Stützgerüst cogeschäumtem, resorbier barem Kollagenschaum mit inkorporierten resorbierbaren permeablen Hohlfaseranordnungen bestehend, die es gestattet, bei durch ope rative Eingriffe entstandenen Wundhöhlen einerseits eine gekop pelte aktive/passive Wundversorgung durchzuführen, andererseits aber auch in diesen Wundhöhlen eine gesteuerte Rekonstruktion mit körpereigenem Gewebe zu erreichen.The invention relates to a tamponade for absorbable, volu menactive cavity protection, preferably made with a poly Urethane structural foam support frame, co-foamed, resorbable barely collagen foam with incorporated absorbable permeable Hollow fiber arrangements existing, which allows, by ope On the one hand, surgical interventions resulted in a wound to carry out active / passive wound care, on the other hand but also in these wound cavities with a controlled reconstruction to reach the body's own tissue.
Es sind Schaumstrukturen (DD-WP 33 1 817 OE A61F 2/02) bzw. tex turierte mä-anderförmige Strukturen (EP 02 59 536 A 2) bekannt, die jedoch nicht für eine temporäre Wundhöhlenprotektion geeignet sind, da sie entweder infolge der verwendeten Werkstoffe und Konstruktionsprinzipien zu unflexibel oder nicht resorbierbar sind, demzufolge durch den Chirurgen des öfteren gewechselt wer den müssen und infolge ihrer relativen Steifigkeit zu mechanisch bedingten Reizungen im Wundbereich führen.Foam structures (DD-WP 33 1 817 OE A61F 2/02) or textured meandering structures (EP 02 59 536 A 2 ) are known, but they are not suitable for temporary wound cavity protection because they are either used as a result of the Materials and construction principles are too inflexible or not absorbable, consequently they have to be changed frequently by the surgeon and, due to their relative stiffness, lead to mechanical irritation in the wound area.
Der Erfindung liegt die Aufgabe zugrunde, ein Gebilde für eine resorbierbare, volumenaktive Wundhöhlenprotektion zu schaffen, das dem Chirurgen einerseits die kontinuierliche sterile und nichtinvasive Entfernung von Exsudat ermöglicht und andererseits eine kontinuierliche Wirkstoffabgabe, wie z. B. Antibiotika, ge stattet. Zusätzlich wird durch die temporäre Stützfunktion der resorbierbaren volumenaktiven Wundhöhlenprotektion ein Einwachsen von körpereigenem Gewebe ohne eine traumatische Druckerhöhung in der Wundhöhle ermöglicht, indem sich ein Gleichgewichtszustand zwischen Gewebewachstum und Resorption des Stützschaumes ein stellt.The invention has for its object a structure for create resorbable, volume-active wound cavity protection, which gives the surgeon the continuous sterile and enables non-invasive removal of exudate and on the other hand continuous drug delivery, such as B. antibiotics, ge equips. In addition, the temporary support function of the resorbable volume-active wound cavity protection ingrowth of the body's own tissue without a traumatic increase in pressure The wound cavity allows for a balance between tissue growth and absorption of the support foam poses.
Das Ziel der Erfindung besteht darin, daß durch Anwendung einer kompatiblen porösen und vor allem weitgehend resorbierbaren Stützeinlage in der Form eines Strukturweichschaumkomposites mit eingelagerten, ebenso resorbierbaren semipermeablen Hohlfasern, sowohl eine Möglichkeit der Dauerspülung der Wundhöhle mit pas siver oder aktiver Drainage nach außen geschaffen wird, als auch die Rekonstruktion der Wundhöhle durch nachwachsendes körpereige nes Gewebe zu unterstützen. Weiterhin soll durch die Stützfunkti on des Weichschaumkomposites ein Kollaps der Wundhöhle verhindert werden bis diese vollständig im Laufe des Heilungsprozesses durch körpereigenes Gewebe ausgefüllt wurde. Die Aufgabe wird erfin dungsgemäß durch die in Anspruch 1 genannten Merkmale gelöst. Der Vorteil der entwickelten resorbierbaren volumenaktiven Wundhöh lenprotektion besteht darin, daß dem Chirurgen die als räumliche Gebilde wie z. B. in Halbkugel-, Hantel- oder Wetzsteinform derge stalt vorkonfektioniert angeboten werden, so daß intraoperativ dem Chirurgen die Möglichkeit eröffnet wird, ohne Funktionsver lust einen paßgenauen Zuschnitt vorzunehmen.The aim of the invention is that by using a compatible porous and above all largely resorbable Support insert in the form of a structural soft foam composite with embedded, equally resorbable semipermeable hollow fibers, both a possibility of continuous irrigation of the wound cavity with pas siver or active drainage is created to the outside, as well the reconstruction of the wound cavity through regrowth of the body to support tissue. Furthermore, by the support function on the soft foam composite prevents collapse of the wound cavity until these are completely through in the course of the healing process body's own tissue has been filled. The task is invented appropriately solved by the features mentioned in claim 1. The Advantage of the developed absorbable volume-active wound cavity lenprotektion is that the surgeon as the spatial Formations such as B. in hemisphere, dumbbell or whetstone shape derge Stalt are offered ready-made, so that intraoperative the surgeon is given the opportunity without a function function want to make a tailor-made cut.
Weiterhin können durch die eingeschäumten resorbierbaren Hohlfa sern sowohl gezielte Medikamentenzugaben, als auch aktive und passive Abscheidungen von Wundhöhlenflüssigkeiten erfolgen.Furthermore, the foamed resorbable Hohlfa targeted drug additions as well as active and passive deposition of sinus fluids takes place.
Ein Ausführungsbeispiel der Erfindung ist im folgenden anhand einer Zeichnung näher dargestellt und beschrieben worden.An embodiment of the invention is based on the following a drawing has been shown and described in more detail.

Gemäß Fig. 1 befinden sich in der Tamponade 1 eingeschäumte, resorbierbare Hohlfasern 2 die mit ihrem einem Ende in Richtung der äußeren Begrenzung ausgerichtet sind, so daß beim endgültigen Zuschneiden durch den Chirurgen unter OP-Bedingungen die Funk tionalität erhalten bleibt. Das zweite Ende der resorbierbaren Hohlfaser 2 ist gebündelt über einen resorbierenbaren Schlauch 3 mit der Außenwelt verbunden.Referring to FIG. 1 are located in the tampon 1 Foamed resorbable hollow fibers 2 which are oriented with their one end in the direction of the perimeter, is so that in the final cutting by the surgeon under operating conditions tionality the radio obtained. The second end of the resorbable hollow fiber 2 is connected to the outside world in bundles via a resorbable tube 3 .
Gemäß Fig. 2 sind in einem offenzelligen Polyurethanweichschaum stützgerüst 4, das einen resorbierbaren Weichschaum 5 umschließt, resorbierbare Hohlfasern 6 eingeschäumt. According to FIG. 2, resorbable hollow fibers 6 are foamed into an open-cell flexible polyurethane foam supporting frame 4 , which encloses a resorbable soft foam 5 .
