Description

Die Erfindung betrifft eine chirurgische Nadel-Faden-Kombination mit am Nadelende befestigtem Faden und einer dem jeweiligen Ver­ wendungszweck angepaßten Form des zwischen Nadelspitze und Nadelende verlaufenden Nadelschaftes, wobei am Nadelende ein mit einer Hinterschneidung ausgebildetes Kupplungsstück ausgebildet ist, dessen Gegenstück mit dem Fadenanfang fest verbunden ist.The invention relates to a surgical needle-thread combination with thread attached to the needle end and a Ver Form of application adapted between the needle tip and Needle end of the extending needle shaft, with a needle at the end an undercut formed coupling piece is, whose counterpart is firmly connected to the beginning of the thread.

Derartige öhrlose Nadel-Faden-Kombinationen, die auch als atraumatisch bezeichnet werden, sind aus der DE 32 23 153 C1 be­ kannt. Ihr wesentlicher Vorteil liegt darin, daß der Stichkanal zum Einbringen des Fadens in das Gewebe nur geringfügig stärker ist als der Fadendurchmesser, wogegen bei mit einem Nadelöhr zum Einfädeln des Fadens versehenen chirurgischen Nadeln die doppelte Fadenstärke in Verbindung mit der im Vergleich zum Nadelschaft aufgeweiteten Öhrpartie den Stichkanal stark auf­ weitet. Grundsätzlich ist eine Aufweitung des Stichkanals auf das Maß des Fadendurchmessers wünschenswert, um das Gewebe beim Durchstechen nur minimal zu schädigen und durch den ein­ gebrachten Faden eventuelle Blutungen zu stillen; die mit Öhr­ nadeln zwangsläufig verbundene starke Aufweitung des Stichkanals ist aber unerwünscht.Such headless needle-thread combinations, which also as are called atraumatic, are from DE 32 23 153 C1 knows. Their main advantage is that the branch channel only slightly stronger for inserting the thread into the tissue is than the thread diameter, whereas with a needle eye to The surgical needles are provided with the thread twice the thread size in connection with the compared to the Needle shaft widened eye section the sting canal expands. Basically, the branch canal is widened the dimension of the thread diameter desirable to the fabric when Pierce only minimally and by the one thread to stop any bleeding; the one with the eye needles inevitably connected strong widening of the branch canal is undesirable.

Um bei öhrlosen Nadeln den Fadenanfang am Nadelende befestigen zu können, wird üblicherweise am Nadelende eine axiale Bohrung angebracht, in die der Faden eingeführt und anschließend durch Zusammenquetschen des gebohrten Nadelendes mittels Klemmung festgehalten wird. Aus der US-PS 4 976 727 ist es darüber hinaus bekannt, am Nadelende eine den Faden umschließende Hülse anzu­ schweißen, um das aufwendige axiale Anbohren des Nadelendes zu vermeiden. Bei diesen bekannten Nadel-Faden-Kombinationen richtet sich die vorher zugeschnittene Fadenlänge nach den An­ forderungen an die jeweilige Nadel-Faden-Kombination. Nach Be­ endigung der chirurgischen Operation und Legung der Naht werden Nadel und Faden durch Abschneiden voneinander getrennt; an­ schließend werden die Fadenenden miteinander verknotet.To attach the beginning of the thread to the end of the needle for eyeless needles To be able to, is usually an axial bore at the needle end attached, into which the thread is inserted and then through Squeeze the drilled needle end together by clamping  is held. It is also known from US Pat. No. 4,976,727 known to attach a thread surrounding sleeve at the needle end welding in order to avoid the complex axial drilling of the needle end avoid. In these known needle-thread combinations the previously cut thread length depends on the type requirements for the respective needle-thread combination. According to Be The surgical operation is completed and the sutures are laid Needle and thread separated by cutting; on finally the thread ends are knotted together.

Die aus der DE 32 23 153 C1 bekannte Nadel-Faden-Kombination er­ möglicht eine Trennung von Nadel und Faden durch Ausüben einer axialen Zugkraft, durch die ein das am Nadelende ausgebildete Kupplungsstück und das am Fadenanfang befestigte Gegenstück un­ lösbar zusammenhaltendes Verbindungsstück im Bereich einer ring­ förmigen Schwächungszone zerstört wird. Eine erneute Verwendung der Nadel - wie sie bei mit einem Nadelöhr versehenen Nadeln ge­ geben ist - ist nicht möglich.The needle-thread combination known from DE 32 23 153 C1 possible separation of needle and thread by exercising one axial tractive force through which a formed at the needle end Coupling piece and the counterpart attached at the beginning of the thread Detachably holding connector in the area of a ring shaped weakening zone is destroyed. Reuse the needle - as is the case with needles with a needle eye giving is - is not possible.

Für spezielle Operationen, primär im Bereich der Gefäßchirurgie, ergibt sich hieraus ein Nachteil. Bei sklerosen Gefäßoperationen mit bis zu 30 Stichen ist vor allem die Nadelspitze wegen der notwendigen Durchdringung kalkhaltiger Ablagerungen innerhalb der Gefäße nach einigen wenigen Einstichen nicht mehr voll funktionsfähig. Die äußerste Nadelspitze verrundet, und dies be­ deutet für den Operateur einen höheren Kraftaufwand für die nachfolgenden Stiche. Dieser erhöhte Kraftaufwand kann wiederum zu einer Verbiegung der Nadel oder sogar zum Nadelbruch führen. Zusätzlich ergibt die nach jedem einzelnen Stich notwendige er­ neute Klemmung der Nadel im Nadelhalter eine Oberflächenbe­ schädigung des Nadelschaftes und damit eine zusätzliche Schädigung der Stichlochränder bei nochmaliger Erhöhung der notwendigen Einstichkraft.For special operations, primarily in the field of vascular surgery, this results in a disadvantage. In sclerotic vascular surgery with up to 30 stitches, the needle point is mainly because of the necessary penetration of calcareous deposits within the vessels are no longer full after a few punctures functioning. The extreme tip of the needle is rounded, and this be indicates a higher effort for the surgeon subsequent stitches. This increased effort can in turn cause the needle to bend or even break. In addition, he gives the necessary after every single stitch again clamp the needle in the needle holder damage to the needle shaft and thus an additional Damage to the tap hole edges if the necessary puncture force.

Aus diesem Grunde wäre insbesondere für die voranstehend be­ schriebene Operationstechnik die Möglichkeit eines Nadelwechsels nach einigen Stichen wünschenswert, wobei der Faden nicht gewechselt werden muß. Ein derartiger Nadelwechsel ist zwar grundsätzlich durch die Verwendung von Öhrnadeln möglich. Da diese jedoch die Forderung nach minimalen Stichlöchern nicht er­ füllen, sind sie für derartige Einsatzbereiche ungeeignet.For this reason, especially for the above be wrote surgical technique the possibility of a needle change after a few stitches desirable, the thread is not  must be changed. Such a needle change is indeed basically possible through the use of eye needles. There however, this did not meet the requirement for minimal stitch holes fill, they are unsuitable for such applications.

Der Erfindung liegt die Aufgabe zugrunde, eine chirurgische Nadel-Faden-Kombination der eingangs beschriebenen Art derart weiterzubilden, daß bei einem bereits mit einigen Einstichen mit dem Gewebe bzw. der Gefäßwand verbundenen Faden ein Wechsel der Nadel möglich ist.The invention has for its object a surgical Needle-thread combination of the type described in the introduction to further develop that with a few punctures the thread connected to the tissue or the vessel wall is a change of Needle is possible.

Die Lösung dieser Aufgabenstellung durch die Erfindung ist dadurch gekennzeichnet, daß das Kupplungsstück und das Gegenstück eine lösbare Steckverbindung bilden, die als eine bis zum Überschreiten einer vorgebbaren Axialkraft formschlüssige Kupplung ausgeführt ist.The solution to this problem by the invention is characterized in that the coupling piece and the Counterpart form a detachable connector that as one to positive form to exceed a predeterminable axial force Clutch is executed.

Durch die erfindungsgemäße Verwendung einer lösbaren Steckver­ bindung zwischen Nadelende und Fadenanfang wird die Möglichkeit geschaffen, eine stumpfgewordene oder beschädigte Nadel auf ein­ fache Weise von einem bereits mit einigen Einstichen vernähten Faden zu lösen, der nach Ansetzen einer neuen Nadel problemlos weitervernäht werden kann. Ein weiterer Vorteil der erfindungs­ gemäßen Steckverbindung besteht in der Möglichkeit einer ver­ ringerten Vorratshaltung, da mit der lösbaren Steckverbindung jeweils gewünschte Nadel-Faden-Kombinationen in jeder Klinik selbst hergestellt werden können, so daß die Chirurgen die für den jeweiligen Eingriff jeweils beste Nadel-Faden-Kombination zur Verfügung gestellt bekommen können. Ein weiterer Vorteil der erfindungsgemäßen Weiterbildung ist schließlich darin zu sehen, daß sich durch eine spezielle Gestaltung des Gegenstückes der Fadenanfang erheblich einfacher und mit besser kontrollierbarer Haltekraft an dem vom Nadelende lösbaren Gegenstück der Steck­ verbindung befestigen läßt, womit aufwendige Verfahren zu Ver­ bindung zwischen Nadel und Fadenanfang vermieden werden, die trotz eines hohen technischen Aufwandes häufig nicht die volle Funktion gewährleisten. The inventive use of a detachable plug-in The possibility between the end of the needle and the beginning of the thread becomes possible created a blunt or damaged needle on one multiple times from one that has already been sewn with a few punctures Loosen thread, which is easy after attaching a new needle can be sewn on. Another advantage of the invention According plug connection is the possibility of a ver reduced stockpiling as with the detachable connector desired needle-thread combinations in each clinic themselves can be made, so that the surgeons for the best possible needle-thread combination can be made available. Another advantage of Finally, further training according to the invention is to be seen in that by a special design of the counterpart Thread start much easier and with more controllable Holding force on the removable counterpart of the plug Connection can be fastened, whereby complex procedures to Ver binding between the needle and the beginning of the thread can be avoided often not the full despite a high technical effort Ensure function.  

Bei einer bevorzugten Ausführungsform der Erfindung ist das am Nadelende angeordnete Kupplungsstück mit einem die nutenartige Hinterschneidung bildenden endseitigen Einführkonus und das Gegenstück mit einem dem Querschnitt der Hinterschneidung ent­ sprechenden Kupplungsring ausgeführt, der am vorderen Ende des hülsenartigen Gegenstückes ausgebildet ist. Hierdurch ergibt sich eine einfache und leicht herstellbare Konstruktion.In a preferred embodiment of the invention, this is the Needle end arranged coupling piece with a the groove-like Undercut forming end insertion cone and that Counterpart with a cross section of the undercut ent speaking coupling ring, which at the front end of the sleeve-like counterpart is formed. This gives a simple and easy to manufacture construction.

Um beim Zusammenstecken bzw. Auseinanderziehen der lösbaren Steckverbindung gemäß der Erfindung die notwendigen Federkräfte zu schaffen, kann entweder der Einführkonus am Kupplungsstück des Nadelendes oder der Kupplungsring am Gegenstück durch mindestens einen axial verlaufenden Schlitz federnd ausgeführt sein. In order to put the detachable ones together or pull them apart Plug connection according to the invention the necessary spring forces to create, either the insertion cone on the coupling piece of the needle end or the coupling ring on the counterpart at least one axially extending slot is resilient his.  

Schließlich wird mit der Erfindung vorgeschlagen, den Fadenan­ fang entweder durch Zusammendrücken der hülsenartigen Aufnahmeöffnung oder mittels eines Klebers mit dem Gegenstück fest zu verbinden.Finally, the invention proposes the thread catch either by squeezing the sleeve-like Opening opening or by means of an adhesive with the counterpart to connect firmly.

Die in den Fig. 1 und 2 jeweils in der Seitenansicht darge­ stellte chirurgische Nadel 1 wird mit einer dem jeweiligen Ver­ wendungszweck angepaßten Form des zwischen der Nadelspitze 2 und dem Nadelende 3 verlaufenden Nadelschaftes 4 ausgeführt. Beim Ausführungsbeispiel ist der Nadelschaft 4 gekrümmt.The surgical needle presented in Figs. 1 and 2 each in the side view Darge 1 is executed each Ver with an intended use of the matched shape of the needle tip between 2 and extending the needle end 3 needle shaft 4. In the exemplary embodiment, the needle shaft 4 is curved.

Das Nadelende 3 wird mit dem Fadenanfang 8 durch eine lösbare Steckverbindung verbunden, die ein am Nadelende 3 angeordnetes Kupplungsstück 5 sowie ein mit dem Fadenanfang 8 fest ver­ bundenes Gegenstück 6 umfaßt. Ein Ausführungsbeispiel dieser Steckverbindung ist vergrößert in den Fig. 3 und 4 dargestellt. The needle end 3 is connected to the beginning of the thread 8 by a releasable plug-in connection, which comprises a coupling piece 5 arranged at the needle end 3 and a counterpart 6 firmly connected to the beginning of the thread 8 . An embodiment of this connector is shown enlarged in FIGS. 3 and 4.

Die Fig. 3 zeigt, daß bei diesem Ausführungsbeispiel das Kupplungsstück 5 einstückig am Nadelende 3 ausgebildet ist. Das Kupplungsstück 5 umfaßt beim Ausführungsbeispiel einen end­ seitigen Einführkonus 5a und eine sich anschließende nutenartige Hinterschneidung 5b. Das Gegenstück 6 ist hülsenartig mit einer auf den Durchmesser des Fadenanfangs 8 abgestimmten Aufnahmeöffnung 6a ausgebildet. Am vorderen Ende bildet das Gegenstück 6 einen dem Querschnitt der Hinterschneidung 5b entsprechenden Kupplungsring 6b. Um die notwendigen Federeigenschaften der Steckverbindung zu erzielen, ist beim Ausführungsbeispiel der Kupplungsring 6b durch axial verlaufende Schlitze 7 federnd aus­ gebildet. Selbstverständlich ist es zur Erzielung der not­ wendigen Federeigenschaften der Steckverbindung auch möglich, das Kupplungsstück 5 mit mindestens einem derartigen Schlitz 7 zu versehen. Fig. 3 shows that in this embodiment, the coupling piece 5 is integrally formed on the needle end 3 . The coupling piece 5 comprises in the embodiment an end-side insertion cone 5 a and a subsequent groove-like undercut 5 b. The counterpart 6 is sleeve-shaped with a receiving opening 6 a which is matched to the diameter of the thread start 8 . At the front end, the counterpart 6 forms a coupling ring 6 b corresponding to the cross section of the undercut 5 b. To achieve the necessary spring properties of the plug connection, the coupling ring 6 b is formed by axially extending slots 7 in the embodiment of the spring. Of course, to achieve the nimble spring properties of the connector, it is also possible to provide the coupling piece 5 with at least one such slot 7 .

Beim Zusammenfügen von Nadel 1 und Fadenanfang 8 wird der vordere Teil des Gegenstückes 6 beim axialen Aufschieben auf den Einführkonus 5a des Kupplungsstückes 5 aufgrund seiner durch die Schlitze 7 erfolgten Aufteilung in Segmente zunächst elastisch federnd aufgeweitet. Sobald jedoch der Kupplungsring 6b in den Bereich der Hinterschneidung 5b des Kupplungsstückes 5 gelangt, federn die Segmente des Kupplungsringes 6b in ihrer Ausgangslage zurück und schaffen eine Art formschlüssige Verbindung zwischen Kupplungsstück 5 und Gegenstück 6, d. h. zwischen der Nadel 1 und dem am Gegenstück 6 befestigten Fadenanfang 8. Die Befestigung des Fadenanfanges 8 erfolgt vorzugsweise durch Zusammendrücken des hinteren Endes des hülsenartigen Gegenstückes 6.When joining together needle thread 1 and the top 8 of the front part of the mating piece 6 during the axial pushing onto the insertion cone 5 a of the coupling member 5 due to its carried out through the slots 7 division into segments is first widened elastically resilient. However, as soon as the coupling ring 6 b reaches the area of the undercut 5 b of the coupling piece 5 , the segments of the coupling ring 6 b spring back in their starting position and create a kind of positive connection between coupling piece 5 and counterpart 6 , ie between the needle 1 and the Counterpart 6 attached thread beginning 8 . The thread beginning 8 is preferably fastened by compressing the rear end of the sleeve-like counterpart 6 .

Die formschlüssige Verbindung zwischen Kupplungsstück 5 und Gegenstück 6 kann jedoch aufgehoben werden, wenn eine vor­ gegebene Axialkraft durch Auseinanderziehen von Nadel 1 und Fadenanfang 8 überschritten wird. In diesem Fall treten die Seg­ mente des Kupplungsringes 6b aus der Hinterschneidung 5b des Kupplungsstückes 5 aus, so daß die Nadel 1 vom Fadenanfang 8 ab­ genommen werden kann. Es ist somit auf einfache Weise möglich, eine verschlissene Nadel während der Operation gegen eine neue Nadel auszutauschen und mit einem bereits teilweise für die Nahtlegung verwendeten Faden die Operation fortzusetzen.The positive connection between coupling piece 5 and counterpart 6 can, however, be canceled if a given axial force is exceeded by pulling needle 1 and thread beginning 8 apart. In this case, the seg ments of the coupling ring 6 b from the undercut 5 b of the coupling piece 5 , so that the needle 1 can be taken from the beginning of the thread 8 . It is thus possible in a simple manner to exchange a worn needle for a new needle during the operation and to continue the operation with a thread already partially used for the suturing.
