Description
- Die vorliegende Erfindung betrifft ein medizinisches Nähmaterial, das beispielsweise in einen herausgeschnittenen Abschnitt eines Gewebe eines Organismus genäht wird, und insbesondere ein medizinisches Nähmaterial eines Typs, das ausgelegt ist, in eine automatische Nähvorrichtung geladen zu werden.
- Die US 5397324 und die EP 0577373 offenbaren derartige automatische Nähvorrichtungen.
- Eine Exzision eines erkrankten Teils eines Gewebes eines Organismus wird im Allgemeinen durch eine chirurgische Operation durchgeführt. Um die Belastung eines Patienten zu verringern, ist die Operation mit einem Endoskop durchgeführt worden.
- Beispielsweise ist eine Exzisionsoperation unter Verwendung einer automatischen Nähvorrichtung durchgeführt worden. Die automatische Nähvorrichtung wird in den Organismus über eine Perforation eingeführt, um das erkrankten Teil herauszuschneiden und den herausgeschnittenen Abschnitt zu nähen. Durch Verwendung des medizinischen Nähmaterials kann ein Vorteil dahingehend verwirklicht werden, dass die Notwendigkeit eines Schnitts des erkrankten Teils beseitigt werden kann. Deswegen weist die automatische Nähvorrichtung an deren führendem Ende einen Nähmechanismusabschnitt zum Halten des herausgeschnittenen Teils des Gewebes eines Organismus auf. Außerdem weist der Nähmechanismusabschnitt eine Vielzahl von Krampenzeilen zum Durchführen der Nähoperation und einen Schneidemechanismus, wie etwa ein Messer, zum Schneiden des Gewebes eines Organismus auf.
- Selbstverständlich ist die Verwendung der automatischen Nähvorrichtung bei der chirurgischen Operation vorteilhaft bei einem Verkürzen der Zeit, die erforderlich ist, um die Näh- und Schnittoperationen zu vollenden, und bei einem Vereinfachen der Operation.
- In einem Fall, wo die automatische Nähvorrichtung verwendet wird, wenn eine Operation eines empfindlichen Gewebes, wie etwa der Lunge, der Bronchien, der Leber, des Verdauungskanals oder dergleichen durchgeführt wird, weist die Nähoperation unter Verwendung der Krampen ein Risiko dahingehend auf, dass das Gewebe zerreißt. In einem Fall einer Operation beispielsweise der Lunge besteht ein Risiko, dass eine Luftleckage auftritt. Da die Luftleckage ein tödliches Problem für den Patienten ist, ist eine zuverlässige Verhinderung erforderlich.
- Dementsprechend ist ein Verfahren eingesetzt worden, in welchem ein Nähmaterial zuvor in die automatische Nähvorrichtung geladen wird, um so an einen herausgeschnittenen Abschnitt des Gewebes eines Organismus genäht zu werden.
- In diesem Fall ist eine Einrichtung erforderlich, um es zu ermöglichen, dass das Nähmaterial in die automatische Nähvorrichtung geladen wird, um so zuverlässig zu dem erkrankten Teil verbracht zu werden. Beispielsweise ist ein Aufbau vorgeschlagen worden, in welchem ein geknüpftes Tuch, das eine Flexibilität aufweist, auf einem Nähmaterial vom Filztyp platziert wird, gefolgt von einem Nähen der beiden Seitenzeilen mit Heftfäden, um eine zylindrische Form zu bilden.
- Jedoch kann das Nähmaterial, das durch ein Nähen des geknüpften Tuchs, das eine Flexibilität aufweist, mit dem Nähfaden gebildet ist, um so in die automatische Nähvorrichtung geladen zu werden, in der Richtung einer Einführung zusammengezogen werden, wenn die automatische Nähvorrichtung in den Organismus eingeführt wird, um in Kontakt mit dem erkrankten Teil gebracht zu werden, was dazu führt, dass das Nähmaterial zu dem Basisabschnitt der automatischen Nähvorrichtung hin versetzt wird oder um die automatische Nähvorrichtung herumgedreht wird. D. h., ein Problem eines Verdrehens tritt auf.
- Wenn das Nähmaterial versetzt oder gedreht ist, kann eine geeignete Behandlung nicht reibungslos durchgeführt werden. Insbesondere stößt eine Operation eines Typs, die mit einem Endoskop durchgeführt wird, auf ein kritisches Problem.
- In dem Lichte des Vorangehenden ist es eine Aufgabe der vorliegenden Erfindung, ein medizinisches Nähmaterial bereitzustellen, das befähigt ist, einen Versatz und ein Drehen zu verhindern, wenn eine automatische Nähvorrichtung eingeführt wird, beispielsweise befähigt dazu, eine Luftleckage zuverlässig zu verhindern, wenn es bei einer Operation der Lunge verwendet wird.
- Um die vorangehende Aufgabe zu lösen, ist ein medizinisches Nähmaterial gemäß der vorliegenden Erfindung, wie in Anspruch 1 offenbart, durch ein Nähen eines Bogenform-Nähmaterials in eine Taschenform gebildet, das ein geschlossenes führendes Ende aufweist, indem ein Nähfaden verwendet wird, um in die automatische Nähvorrichtung geladen zu werden, die eine Krampenzeile aufweist.
- Das Nähmaterial gemäß der vorliegenden Erfindung weist das Hauptnähmaterial auf, das ein Material, wie etwa ein ungewebter Stoff, wie etwa Filz, ein gewebter Stoff oder ein geknüpftes Tuch sein kann, wenn es eine gewisse Flexibilität und Dehnbarkeit aufweist. Ein bekanntes Material kann eingesetzt werden. In Anbetracht des Zustands nach der Operation ist es vorzuziehen, dass ein bioabsorbierbares Polymer, wie etwa Polyglykolsäure, oder ein Abschnitt eines Gewebes eines Organismus, beispielsweise der Organschutzfilm, wie etwa der Herzsack, eingesetzt wird.
- Das oben erwähnte Nähmaterial kann in die Taschenform durch ein Nähen eines Tuchmaterials durch den Nähfaden gebildet werden, oder eine Vielzahl von beispielsweise zwei Nähmaterialien können in die Taschenform genäht werden. In dem letzteren Fall können die beiden Nähmaterialien das gleiche Material sein oder können unterschiedliche Materialien sein. Eines der beiden Nähmaterialien kann ein Material außer dem Nähmaterial, beispielsweise ein übliches geknüpftes Tuch sein.
- Da das Nähmaterial gemäß der vorliegenden Erfindung die Taschenform aufweist, die das geschlossene führende Ende durch ein Nähen aufweist, kann ein Versatz, der aufgrund einer Schrumpfung in der Einführungsrichtung auftreten kann, verhindert werden, wenn die automatische Nähvorrichtung eingeführt wird.
- Da das Nähmaterial, das in die Taschenform von einer oder einer Vielzahl von Nähmaterialien durch ein Nähen gebildet ist, den Aufbau aufweist, in welchem die gesamte Oberfläche aus nur dem Nähmaterial ausgeführt ist, tritt kein Problem auf, auch wenn es unbeabsichtigt gedreht (verdreht) wird.
- In den Zeichnungen zeigen:
- Fig. 1 eine schematische perspektivische Ansicht, die ein Beispiel eines Nähmaterials gemäß der Erfindung zeigt;
- Fig. 2 eine schematische perspektivische Ansicht, die ein Beispiel einer automatischen Nähvorrichtung zeigt, in welcher das Nähmaterial verwendet wird;
- Fig. 3 eine schematische ebene Ansicht, die einen wesentlichen Abschnitt eines Nähmechanismusabschnitts der automatischen Nähvorrichtung zeigt;
- Fig. 4 eine schematische perspektivische Ansicht, die einen Zustand zeigt, wo das Nähmaterial in die automatische Nähvorrichtung geladen worden ist;
- Fig. 5 eine schematische perspektivische Ansicht, die einen Zustand einer Nähoperation unter Verwendung der automatischen Nähvorrichtung zeigt;
- Fig. 6 eine schematische perspektivische Ansicht, die einen Zustand zeigt, wo die Nähbehandlung beendet worden ist; und
- Fig. 7 eine schematische perspektivische Ansicht, die ein weiteres Beispiel des Nähmaterials gemäß der vorliegenden Erfindung zeigt.
- Bevorzugte Ausführungsformen der vorliegenden Erfindung werden nun im Detail unter Bezugnahme auf die Zeichnungen beschrieben werden.
- Ein medizinisches Nähmaterial 1 gemäß dieser Ausführungsform, wie in Fig. 1 gezeigt, ist in der Form einer Taschenform, die ein geschlossenes führendes Ende aufweist, indem ein Hauptmaterial 2, das aus einem Filz (beispielsweise NEOVEIL, der ein Handelsnamen von Gunze Kabushiki Kaisha ist) ausgeführt ist, der beispielsweise aus einer absorbierbaren Polyglykolsäure besteht, unter Verwendung eines Nähfadens genäht wird. Wie oben beschrieben, ist der Aufbau sehr einfach.
- Das Hauptnähmaterial 2 kann ein bekanntes Nähmaterial, wie auch das bioabsorbierbare Polymer, wie etwa die absorbierbare Polyglykolsäure, sein. Beispielsweise kann ein Abschnitt eines Gewebes eines Organismus, wie etwa ein Organschutzfilm, der durch den Herzsack veranschaulicht ist, eingesetzt werden.
- Das Hauptnähmaterial 2 wird in eine längliche Form gebildet, die eine Länge aufweist, die im Wesentlichen die gleiche wie jene eines Ladeabschnitts einer automatischen Nähvorrichtung ist, die später zu beschreiben ist. Das Hauptnähmaterial 2 wird in zwei gefaltet und dann entlang eines Seitenabschnitts in der Breitenrichtung mit einem Nähfaden 3 genäht, der ein Faden zum Nähen ist.
- Es ist vorzuziehen, dass die Nähfäden 3 so genannte Monofilamente hinsichtlich eines einfachen Ziehens sind, während das Material derselben willkürlich bestimmt werden kann. Beispielsweise kann ein bioabsorbierbarer Polymerfaden oder ein Polyamidfaden (Handelsname: Nylonfaden), der eine ausgezeichnete Gleiteigenschaft aufweist, vorzugsweise eingesetzt werden.
- Das medizinische Nähmaterial, das den oben erwähnten Aufbau aufweist, wird in die automatische Nähvorrichtung geladen. Der Aufbau der automatischen Nähvorrichtung und das Verfahren, das medizinische Nähmaterial gemäß dieser Ausführungsform zu verwenden, werden nun beschrieben werden.
- Wie in Fig. 2 gezeigt, weist die automatische Nähvorrichtung an dem führenden Ende der Welle 11 davon einen Nähabschnitt 12 auf, der geöffnet/geschlossen werden kann. Die automatische Nähvorrichtung weist in dem Basisabschnitt davon einen Operationsabschnitt 13 auf, der angeordnet ist, gehalten zu werden, und mit welchem eine Operation der automatischen Nähvorrichtung durchgeführt wird.
- Wie in Fig. 3 gezeigt, weist der Nähabschnitt 12 einen Nähmechanismusabschnitt 12a, auf welchem eine Kassette, die Krampen aufnimmt, und eine Messerklinge angebracht sind; und einen Klauenabschnitt 12b zum Halten eines Gewebes eines Organismus auf. Eine Vielzahl von (3 Zeilen · 3 Zeilen = 6 Zeilen) von Krampenzeilen 14 und eine Messerabtastzeile 15 stehen der Haltefläche des Nähmechanismusabschnitts 12a gegenüber.
- Die automatische Nähvorrichtung wird in den Organismus über eine Anordnung, die als ein "Surge-Boat" bezeichnet wird, eingeführt. D. h., das Surge-Boat wird an einer Perforation angebracht, die in dem Organismus gebildet ist, und dann wird die Welle 11 der automatischen Nähvorrichtung in den Organismus über das Surge-Boat eingeführt. Folglich kann die Perforation, die in dem Organismus gebildet wird, abgedichtet werden.
- Das medizinische Nähmaterial 1 wird in den Nähabschnitt 12 der automatischen Nähvorrichtung bei Gebrauch eingeführt. Fig. 4 zeigt einen Zustand, wo das Nähmaterial 1 in den Nähabschnitt 12 der automatischen Nähvorrichtung geladen worden ist, derart, dass das Nähmaterial 1 an dem Nähmechanismusabschnitt 12a und dem Klauenabschnitt 12b befestigt ist.
- Das Nähmaterial 1 kann reibungslos in den Nähabschnitt 12 durch ein Abdecken des Nähabschnitts 12 mit dem Nähmaterial 1 der Taschenform eingeführt werden.
- In dem oben erwähnten Zustand wird die automatische Nähvorrichtung in den Organismus über das Gleitboot eingeführt, wie oben beschrieben, um zu dem erkrankten Teil verbracht zu werden. Da das Nähmaterial 1, das in die automatische Nähvorrichtung zu laden ist, eine Form aufweist, die derart angeordnet ist, dass der geschlossene Abschnitt des Taschenaufbaus hereingeschoben wird, können ein Versatz und ein Verdrehen verhindert werden.
- Nachdem der Nähabschnitt 12 in das erkrankte Teil eingeführt worden ist, wird der herausgeschnittene Abschnitt des Gewebes eines Organismus 12 durch den Nähmechanismusabschnitt 12a und den Klauenabschnitt 12b gehalten, wie in Fig. 5 gezeigt. Folglich ist der herausgeschnittene Abschnitt mit dem Hauptnähmaterial 2 bedeckt.
- Dann wird ein Operationshebel 13a, der für den Operationsabschnitt 13 der automatischen Nähvorrichtung bereitgestellt ist, derart betätigt, dass Krampen durch den Operationsabschnitt 13 getrieben werden.
- Folglich werden die Krampen entlang des herausgeschnittenen Abschnitts des Gewebes des Organismus 20 getrieben, so dass die Nähbehandlung durchgeführt wird. Gleichzeitig wird das Hauptnähmaterial 2 des Nähmaterials 1, das in den Nähabschnitt 12 geladen ist, gegen den herausgeschnittenen Abschnitt des Gewebes des Organismus 20 gedrückt, um so durch die Krampen genäht zu werden.
- Das Hauptnähmaterial 2 dient als ein Verstärkungselement, wenn die Nähoperation durchgeführt wird. Durch ein Nähen des herausgeschnittenen Abschnitts des Gewebes des Organismus 20 durch das Hauptnähmaterial 2 kann ein Reißen des Gewebes verhindert werden. Somit kann eine Exzisionsoperation eines großen Sacculus Alveolaris ohne eine Luftleckage durchgeführt werden.
- Dann wird das Messer, das für den Nähmechanismusabschnitt 12a bereitgestellt ist, entlang der Abtastzeilen 15 abgetastet, um das Gewebe des Organismus 20 und das Hauptnähmaterial 2 zu schneiden.
- Somit ist die Nähbehandlung beendet. Durch ein Verwenden des Nähmaterials 1 gemäß dieser Ausführungsform kann die Nähoperation reibungslos durchgeführt werden. Außerdem kann der genähte Abschnitt zuverlässig verstärkt werden, und eine Luftleckage aus demselben kann verhindert werden. Fig. 6 zeigt den Zustand einer Beendigung der Nähoperation, in welchem das Hauptmaterial 2 mit dem genähten Abschnitt des Gewebes des Organismus 20 durch die Nähoperation verbunden ist. Der Zustand eines Nähens kann beträchtlich stabilisiert werden.
- Ein Nähmaterial 21 gemäß dieser Ausführungsform wird, wie in Fig. 7 gezeigt, durch ein Nähen zweier Nähmaterialien 22 und 23 in eine Taschenform, die ein geschlossenes führendes Ende aufweist, gebildet.
- Jedes der Nähmaterialien 22 und 23 wird in eine Form gebildet, die eine Breite aufweist, die in einer Richtung zu dem führenden Ende davon hin verringert ist. Die beiden Seitenenden werden durch Nähfäden 24 und 25 genäht. Die Nähfäden 24 und 25 sind ausgeführt, sich an den führenden Enden der Nähmaterialien 22 und 23 entsprechend der Formen der Nähmaterialien 22 und 23 zu kreuzen, so dass ein Nähen des Taschenaufbaus zuverlässig ausgeführt wird.
- Die Nähmaterialien 22 und 23 können aus dem gleichen Material oder unterschiedlichen Materialien ausgeführt sein. Spezifisch ist das erste Nähmaterial 22 aus einem Filz einer absorbierbaren Polyglykolsäure (beispielsweise NEOVEIL, das ein Handelsname von Gunze Kabushiki Kaisha ist) ausgeführt, während das zweite Nähmaterial 23 aus einem weiteren Material ausgeführt ist.
- Durch ein Verwenden unterschiedlicher Materialien können die Kosten verringert werden, und deswegen kann ein Vorteil bei dem Herstellungsprozess verwirklicht werden.
- Auch ist das Nähmaterial gemäß dieser Ausführungsform ähnlich zu dem Nähmaterial gemäß der Ausführungsform 1, das in die automatische Nähvorrichtung bei Gebrauch geladen wird. Das Verfahren eines Verwendens derselben ist ähnlich zu jenem gemäß der Ausführungsform 1.
- Obwohl die Erfindung bezüglich ihrer bevorzugten Form mit einem gewissen Grad einer Spezifität beschrieben worden ist, ist es zu verstehen, dass die vorliegende Offenbarung in der bevorzugten Form in den Details eines Aufbaus und in der Kombination und Anordnung der Teile geändert werden kann.
- Das Nähmaterial gemäß der vorliegenden Erfindung ist befähigt, einen Versatz zu verhindern, der aufgrund einer Schrumpfung auftritt, wenn die automatische Nähvorrichtung eingeführt wird. Auch wenn ein Verdrehen stattfindet, kann das Nähmaterial immer in Kontakt mit dem erkrankten Teil sein.
- Deswegen ermöglicht es die Verwendung des Nähmaterials gemäß der vorliegenden Erfindung, dass der genähte Abschnitt zuverlässig Verstärkt wird. Folglich können ein Reißen des Gewebes und eine Luftleckage verhindert werden.
