Abstract

A surgical clip suture apparatus for producing circular joins (anastomoses) has an elongate apparatus body through which there is a drilled hole and at one end of which there is an annular clip magazine which is arranged concentrically to the drilled hole. On the side of the clip magazine facing away from the apparatus body there is an annular counter-pressure plate for bending over the U-shaped clips; it is attached to the end of a tension bar which passes, secured against rotation, through the hole drilled in the apparatus body to an actuation member. According to the invention, the tension bar can be removed, in whole or in part, with the counter-pressure plate located thereon in the direction of the end of the apparatus body having the clip magazine. This makes it possible to produce circular joins even at places which are difficult to get at, e.g. above the diaphragm, without it being necessary to open the thoracic cavity, which is a considerable stress for the patient. <IMAGE>

Description

Chirurgisches Klammernahtgerät zur Herstellung Manufacturing surgical stapler

zirkulärer Verbindungen Die Erfindung betrifft ein chirurgisches Klammernahtgerät zur Herstellung zirkulärer Verbindungen (Anastomosen) der im Oberbegriff des Patentanspruchs 1 genannten Art. Circular Connections The invention relates to a surgical one Stapling device for making circular connections (anastomoses) of the generic term of claim 1 mentioned Art.

Ein chirurgisches Klammernahtgerät der betreffenden Art ist durch die US-PS 3 193 165 und 3 494 533 bekannt und wird von der Firma Auto Suture Company in Stamford, Conn./USA. A surgical stapler of the type in question is through U.S. Patents 3,193,165 and 3,494,533 and is made by Auto Suture Company in Stamford, Conn./USA.

vertrieben. Die Zugstange ist dabei im Gebrauch unlösbar mit dem Gerätekörper verbunden und zu Reinigungszwecken auch nur nach Abnehmen der Gegendruckplatte in Richtung des das Betätigungsglied aufweisenden Endes des Gerätekörpers nach hinten herausziehbar.expelled. The pull rod is inseparable from the device body during use connected and for cleaning purposes only after removing the counter pressure plate in Direction of the end of the device body having the actuating member towards the rear pull-out.

Dieses bekannte Klammernahtgerät wird in der Weise verwendet, daß z.B. zwei miteinander zu verbindende Darmenden einmal von dem langgestreckten Gerätekörper her über das Klammermagazin und einmal über die pilzförmige Gegendruckplatte geschoben und dann mittels Tabaksbeutelnähten gegen die Zugdie Zugstange stange zusammengezogen werden. Danach wird/durch Betätigen eines als auf ihrem Gewindeende aufgeschraubte Flügelmutter ausgebildeten Betätigungsgliedes zurückgezogen und damit die Gegendruckplatte gegen das Klammermagazin gedrückt. Danach werden die ursprünglich U-förmigen Klammern mit ihren Spitzen durch die Darmwände gestochen und durch die Gegendruckplatte mit den darin befindlichen Vertiefungen umgebogen. This known stapling device is used in such a way that E.g. two intestinal ends to be connected to each other once from the elongated device body pushed over the staple magazine and once over the mushroom-shaped counter-pressure plate and then pulled the pull rod together against the pull using purse-string sutures will. Then / by pressing one than on their thread end unscrewed wing nut trained actuator withdrawn and thus the counter pressure plate pressed against the staple magazine. After that, the originally U-shaped staples with their tips pierced through the intestinal walls and through the Counterpressure plate bent over with the indentations in it.

Gleichzeitig wird mittels eines hier nicht weiter interessierenden ringförmigen Stanzmessers der radial weiter innenliegende Teil der Darmenden mit den Tabaksbeutelnähten ausgestanzt und damit die Durchgängigkeit des Darmkanals wieder hergestellt. Danach kann das Klammernahtgerät weggezogen werden, so daß eine zirkuläre Verbindung zwischen den radial nach innen weisenden Rändern von Darmenden gebildet ist.At the same time, one is not of further interest here ring-shaped punching knife with the part of the intestinal ends lying further radially inwards punched out the purse-string sutures and thus the patency of the intestinal canal restored. Then the stapler can be pulled away so that a circular connection between the radially inwardly pointing edges of the intestinal ends is formed.

Die Einführung insbesondere der Gegendruckplatte in das entsprechende Darmende und das Anbringen der Tabaksbeutelnaht um diese Gegendruckplatte erfordert eine gewisse Zugänglichkeit und übersicht. Diese ist im Bauchraum überall gegeben. The introduction of the counter pressure plate in particular into the corresponding Requires the end of the intestine and the attachment of the purse-string suture around this counter-pressure plate some accessibility and overview. This is given everywhere in the abdomen.

Wird aber beispielsweise bei einer Tumorbildung der untere Teil der Speiseröhre entfernt, so ist es erforderlich, diese Defektstrecke durch Hochziehen des Magens oder eines Darmanteils zu überbrücken. Hierzu sind in der Regel Kombinationseingriffe, sogenannte Zweihöhleneingriffe, erforderlich. Dabei wird durch einen Zugang über die Bauchhöhle zunächst eine Darmschlinge zur Überbrückung präpariert und die Entfernung des Tumors vorbereitet. Nach Verschluß der Bauchhöhle wird dann bei derselben Sitzung die Brusthöhle eröffnet, um den betreffenden Speiseröhrenabschnitt entfernen und den belassenen Anteil mit der hochgezogenen Darmschlinge vereinigen zu können. Die Eröffnung der Brusthöhle stellt für die meist in höherem Alter befindlichen Patienten eine erhebliche Belastung dar. If, however, the lower part of the The esophagus is removed so it is necessary to stretch this defect by pulling it up of the stomach or part of the intestine. This usually involves combination interventions, so-called two-cave interventions, required. This is done through an access via the abdominal cavity is first prepared with a loop of intestine to bridge the gap and then removed of the tumor prepared. After the abdominal cavity has been closed, the same session takes place the chest cavity is opened to remove the affected esophageal section and unite the portion left with the loop of intestine that has been pulled up to can. The opening of the thoracic cavity is usually a problem for the elderly Pose a significant burden to patients.

Das bekannte Klammernahtgerät ist in dem genannten Fall nicht anwendbar, da die Durchtrittsstelle der Speiseröhre durch das Zwerchfell relativ eng ist und bei Anwendung des bekannten Klammernahtgerätes durch das Klammermagazin mit dem dieses umgreifenden Ende des Darmes oder des Anteils des Magens so verdeckt werden würde, daß es nicht mehr möglich ist, die pilzförmige Gegendruckplatte kontrolliert in die Speiseröhre einzuführen oder die Tabakbeutelnaht dort anzubringen. Bei höherliegenden Anastomosen ist daher auch bei Verwendung dieses bekannten Klammernahtgerätes die Erfindung des Brustkorbes mit den damit verbundenen Nachteilen erforderlich. The well-known stapling device cannot be used in the case mentioned, because the passage point of the esophagus through the diaphragm is relatively narrow and when using the known stapling device through the staple magazine with the this encompassing end of the intestine or that part of the stomach are covered would that it is no longer possible to control the mushroom-shaped counter-pressure plate insert it into the esophagus or apply the tobacco pouch suture there. With higher lying Anastomoses is therefore also the case when using this known stapling device Invention of the rib cage with its associated disadvantages is necessary.

Der Erfindung liegt die Aufgabe zugrunde, ein Klammernahtgerät der betreffenden Art zu schaffen, mit dem auch zirkuläre Verbindungen an schwer zugänglichen Stellen, insbesondere oberhalb des Zwerchfells, herstellbar sind. The invention is based on the object of providing a stapler to create the relevant type, with which circular connections are difficult to access Places, in particular above the diaphragm, can be produced.

Die der Erfindung zugrundeliegende Aufgabe wird dadurch gelöst, daß die Zugstange ganz oder ein der Gegendruckplatte benachbarter Teil davon in Richtung des das Klammermagazin aufweisenden Ende des Gerätekörpers abnehmbar ist. The object on which the invention is based is achieved in that the pull rod in its entirety or a part thereof adjacent to the counter pressure plate in the direction of the end of the device body having the staple magazine is removable.

Bei einem gemäß dieser Lehre der Erfindung ausgestalte ten Klammernahtgerät ist es möglich, zunächst die Zugstange oder einen davon abnehmbaren Teil mit der daran befestigten Gegendruckplatte abzunehmen, so daß die Gegendruckplatte ohne Behinderung durch das übrige Klammernahtgerät, insbesondere das Klammermagazin, beispielsweise in ein Speiseröhrenende eingeführt und dort die erforderliche Tabakbeutelnaht angebracht werden kann. In a stapler configured according to this teaching of the invention it is possible to first use the pull rod or a detachable part with the to remove the counter pressure plate attached, so that the counter pressure plate without Obstruction by the rest of the stapler, in particular the Staple magazine, for example inserted into an end of the esophagus and there the required Tobacco pouch seam can be attached.

Danach wird in einem zweiten Arbeitsschritt das vordere Ende des Gerätekörpers mit dem Klammermagazin von unten in den Darm eingeführt und in der Mitte des Magazins, also im Bereich des Austritts der Bohrung in dem Gerätekörper, ein Darmwanddefekt angebracht. Danach wird durch diesen Darmwanddefekt die Zugstange in das Klammernahtgerät eingeführt und mit dem restlichen Teil der Zugstange oder mit dem Betätigungsglied verbunden. Danach kann der Nahtvorgang wie oben beschrieben ausgeführt werden. Then, in a second step, the front end of the Device body with the staple magazine inserted from below into the intestine and in the Center of the magazine, i.e. in the area of the exit of the hole in the device body, an intestinal wall defect attached. Then the pull rod becomes through this intestinal wall defect inserted into the stapler and with the remaining part of the pull rod or connected to the actuator. The sewing process can then be carried out as described above are executed.

Eine Weiterbildung der Erfindung ist im Anspruch 2 angegeben. Nach dieser Lehre erstreckt sich die Längsnut in der Zugstange zur Drehsicherung nicht nur über den vorderen, den Nahtmitteln zugewandten Bereich, sondern vollständig bis nach hinten, so daß sie also nach hinten offen ist, so daß die gesamte Zugstange nach Lösen von dem Betätigungsglied, vorzugsweise nach Lösen einer an sich bekannten Flügelmutter von einem Gewinde am hinteren Ende der Zugstange, nach vorn herausziehbar ist. Die Flügelmutter ist dabei zweckmäßigerweise drehbar mit dem Gerätekörper verbunden, sie kann aber auch lose sein, was den Vorteil hat, daß das Erscheinen des hinteren Gewindeendes der Zugstange erkennbar ist. A further development of the invention is specified in claim 2. To this teaching does not extend the longitudinal groove in the pull rod to prevent rotation only over the front area facing the seams, but completely to the rear, so that it is open to the rear, so that the entire pull rod after releasing from the actuator, preferably after releasing a known per se Wing nut from a thread at the rear end of the pull rod, can be pulled out towards the front is. The wing nut is expediently rotatably connected to the device body, but it can also be loose, which has the advantage that the appearance of the rear Thread end of the pull rod can be seen.

Nach der im Anspruch 5 angegebenen Lehre ist nur der der Gegendruckplatte benachbarte Teil der Zugstange abnehmbar, und zwar aufgrund einer Bajonettverbindung, die gleichzeitig die für eine Funktion der Klammervorrichtung wichtige bestimmte Drehlage der Gegendruckplatte in bezug zu dem Klammermagazin sicherstellt. According to the teaching given in claim 5, only that of the counter pressure plate Adjacent part of the pull rod can be removed due to a bayonet connection, the same time which is important for a function of the clamping device certain rotational position of the counter pressure plate in relation to the staple magazine ensures.

Anhand der Zeichnung soll die Erfindung näher erläutert werden. The invention is to be explained in more detail with the aid of the drawing.

Fig. 1 ist eine Gesamtansicht eines Ausführungsbeispiels des Klammernahtgerätes gemäß der Erfindung, Fig. 2 zeigt vergrößert und im Schnitt den hinteren Teil des Klammernahtgerätes gemäß Fig. 1, Fig. 3 zeigt vergrößert die Zugstange des Klammernahtgerätes gemäß Fig. 1, Fig. 4 zeigt vergrößert das vordere Ende einer anderen Ausführungsform einer Zugstange, bei der das vordere Ende abnehmbar ist, Fig. 5 verdeutlicht die Unbrauchbarkeit des bekannten Klammernahtgerätes bei einer Speiseröhrenoperation, Fig. 6 bis 8 verdeutlichen drei wesentliche Arbeitsschritte bei der Verwendung eines Klammernahtgerätes gemäß der Erfindung. Fig. 1 is an overall view of one embodiment of the stapler according to the invention, Fig. 2 shows enlarged and in section the rear part of the Staple suture device according to Fig. 1, Fig. 3 shows an enlarged view of the pull rod of the staple suture device according to Fig. 1, Fig. 4 shows enlarged the front end of another embodiment a pull rod in which the front end is removable, Fig. 5 illustrates the The well-known stapler is unusable during esophageal surgery, FIGS. 6 to 8 illustrate three essential steps in the use of a Stapler according to the invention.

Das in Fig. 1 gezeigte Klammernahtgerät weist einen Gerätekörper 1 auf, an dessen vorderem Ende sich ein Klammer-2 magazin/befindet und durch das eine in der vergrößerten Teilschnittdarstellung gemäß Fig. 2 ersichtliche Bohrung 3 verläuft, durch die eine Zugstange 4, auf deren Gewindeende 7 eine Flügelmutter 6 aufschraubbar ist, führt, mit deren Hilfe ein Zug auf die Zugstange 4 ausübbar ist. The stapler shown in Fig. 1 has a device body 1, at the front end of which there is a staple 2 magazine / and through the a bore visible in the enlarged partial sectional view according to FIG. 2 3 runs through which a tie rod 4, on the threaded end 7 of which a wing nut 6 can be screwed on, leads, with the help of which a train on the pull rod 4 is exercisable.

Mit Hilfe eines als Handgriff ausgebildeten Betätigungsgliedes 5 wird das Klammermagazin 2 betätigt.With the help of an actuator 5 designed as a handle the staple magazine 2 actuated.

An dem vorderen Ende der Zugstange 4 befindet sich eine in der Axialansicht ringförmige und in der Seitenansicht pilzförmige Gegendruckplatte 8, in der sich gegenüber von in das Klammermagazin einsetzbaren U-förmigen Klammern Vertiefungen befinden, die bei Bewegung der Gegendruckplatte 8 gegen das Klammermagazin 2 umgebogen werden. In dem Klammermagazin 2 befindet sich außerdem ein ringförmiges Stanzmesser das hier nicht weiter von Interesse ist. In der Zugstange 4 befindet sich eine Längsnut 9, die sich über die gesamte Ausdehnung der Zugstange erstreckt und somit auch nach hinten offen ist. At the front end of the pull rod 4 there is one in the axial view annular and in the side view mushroom-shaped counter pressure plate 8, in which opposite of insertable in the clip magazine U-shaped clips depressions which are bent over against the staple magazine 2 when the counter-pressure plate 8 is moved will. In the staple magazine 2 there is also an annular punch knife which is of no further interest here. There is a longitudinal groove in the pull rod 4 9, which extends over the entire extension of the pull rod and thus also after is open at the back.

In die Längsnut 9 greift ein an dem Gerätekorper 1 befindlicher Stift ein, so daß die Zugstange 4 in einer bestimmten Drehlage zu dem Gerätekörper 1 und auch zu dem Klammermagazin 2 geführt ist. Die Zugstange ist als Ganzes in Fig. 3 gezeigt. Wegen der nach hinten offenen Längsnut 9 ist die Zugstange 4 nach Lösen der Flügelmutter 6 nach vorn, also in Richtung auf das das Klammermagazin aufweisende Ende des Gerätekörpers 1 herausziehbar.A pin located on the device body 1 engages in the longitudinal groove 9 a, so that the pull rod 4 in a certain rotational position to the device body 1 and is also led to the staple magazine 2. The pull rod is shown as a whole in FIG. 3 shown. Because of the rearwardly open longitudinal groove 9, the pull rod 4 is after loosening the wing nut 6 forward, that is, in the direction of the one having the staple magazine The end of the device body 1 can be pulled out.

Fig. 4 verdeutlicht eine andere Ausführungsform der Erfindung, bei der die Zugstange aus zwei Zugstangenteilen 10 und 11 besteht. Das Zugstangenteil 10 kann fest mit dem Betätigungsglied, beispielsweise dem Betätigungsglied der Ausführungsform nach Fig. 1, wirkungsverbunden sein. Das dem Betätigungsglied abgewandte Ende des Zugstangenteils 10 weist eine Bohrung 12 auf, in die ein langer Zapfen 13 des Zugstangenteils 11 spielfrei eingreift und mit seinem Ende 14 gegen eine Druckfeder 15 drückt. In dem Ende des Zugstangenteils 10 befindet sich eine L-förmige Nut 16, in die ein Stift 17 eingreift, der sich in dem Zapfen 13 befindet. Nut 16 und Stift 17 bilden in Verbindung mit der Druckfeder 15 eine Bajonettverbindung,die die Zugstangenteile 10 und 11 in einer bestimmten Drehlage lösbar miteinander verbindet. Somit fluchten auch Führungsnutenteile 18 und 19, die eine bestimmte Drehlage wie die Längsnut 9 (Fig. 2 und 3) gewährleisten. Fig. 4 illustrates another embodiment of the invention, at which the tie rod consists of two tie rod parts 10 and 11. The tie rod part 10 can be fixed to the actuator such as the actuator of the embodiment according to Fig. 1, be functionally connected. The end of the remote from the actuator Tie rod part 10 has a hole 12 into which a long Pin 13 of the tie rod part 11 engages without play and with its end 14 against a compression spring 15 presses. In the end of the tie rod part 10 there is one L-shaped groove 16 in which a pin 17 located in the pin 13 engages. Groove 16 and pin 17 form, in conjunction with the compression spring 15, a bayonet connection which the tie rod parts 10 and 11 releasably connect to one another in a certain rotational position. Thus, guide groove parts 18 and 19, which have a certain rotational position such as ensure the longitudinal groove 9 (Fig. 2 and 3).

Fig. 5 verdeutlicht die Schwierigkeiten bei Verwendung des bekannten Klammernahtgerätes bei einer Speiseröhrenoperation. Es ist gezeigt, wie am Ende eines Darmes 20 eine Darmschlinge 21 präpariert und mit einem Durchtritt 22 versehen ist, durch die eine pilzförmige Gegendruckplatte 23 mit einer Zugstange 24 geschoben ist. Nach der Darstellung sind außerdem die Gegendruckplatte 23 und die Zugstange 24 bereits durch die Durchtrittsstelle 25 (hiatus oesophageus) in einem Zwerchfell 26 geschoben, um so mit der Gegendruckplatte 23 in den Bereich eines an die Darmschlinge 21 anzuschließenden Endes einer Speiseröhre 27 zu gelangen. Es wird deutlich, daß die Darmschlinge 21 und ein darin befindliches Klammermagazin 28 des Klammernahtgerätes die Durchtrittsstelle 25 weitgehend verdecken, so daß es praktisch nicht mehr möglich ist, das Ende der Speiseröhre 27 über die Gegendruckplatte 23 zu schieben und die erforderliche Tabakbeutelnaht anzubringen. Fig. 5 illustrates the difficulties in using the known Stapler during an esophageal operation. It is shown how at the end of an intestine 20, an intestinal loop 21 is prepared and provided with a passage 22 is through which a mushroom-shaped counter-pressure plate 23 with a pull rod 24 is pushed is. According to the illustration, the counter pressure plate 23 and the pull rod are also shown 24 already through the passage point 25 (hiatus oesophageus) in a diaphragm 26 pushed so with the counter-pressure plate 23 in the area of one on the intestinal loop 21 end of an esophagus 27 to be connected. It becomes clear that the intestinal loop 21 and a staple magazine 28 of the staple suture device located therein cover the passage point 25 largely so that it is practically no longer possible is to push the end of the esophagus 27 over the counter pressure plate 23 and the to attach the necessary tobacco pouch seam.

Die Fig. 6 bis 8 zeigen die Verwendung des erfindungsgemäß gestalteten Klammernahtgerätes, wobei die Körperteile in übereinstimmung mit Fig. 5 mit gleichen Bezugsziffern bezeichnet sind. FIGS. 6 to 8 show the use of the device designed according to the invention Stapler, with the body parts in accordance with Fig. 5 are denoted by the same reference numerals.

Aus Fig. 6 ist zu erkennen, da die Zugstange 4, bei der es sich auch um das Zugstangenteil 11 der Ausführungsform gemäß Fig. 4 handeln könnte, mit der Gegendruckplatte 8 durch die Durchtrittsöffnung 25 in dem Zwerchfell 26 geführt ist, wonach das Ende der Speiseröhre 27 über die Gegendruckplatte 8 geschoben ist. Die Fig. 6 verdeutlicht den Augenblick, in dem mittels einer Nadel 29 und eines Fadens 30 durch den Durchtritt 25 hindurch das Ende der Speiseröhre 27 auf der Zugstange 4 fixiert wird. From Fig. 6 it can be seen that the pull rod 4, which is also could be the tie rod part 11 of the embodiment according to FIG. 4, with the Counter-pressure plate 8 passed through the passage opening 25 in the diaphragm 26 is, after which the end of the esophagus 27 is pushed over the counter-pressure plate 8. Fig. 6 illustrates the moment in which by means of a needle 29 and a Thread 30 through the passage 25 through the end of the esophagus 27 on the pull rod 4 is fixed.

Fig. 7 verdeutlicht den nächsten Operationsschritt, bei dem wie bei Fig. 5 die Darmschlinge 21 präpariert und das Klammermagazin 2 mit dem vorderen Ende des Gerätekörpers 1 eingeführt ist. In die Darmschlinge 21 ist koaxial zu dem Klammermagazin 2 ein Defekt 31 eingebracht, durch den die Zugstange 4 in die innere Bohrung 3 (Fig. 2) des Gerätekörpers 1 eingeführt und mittels der Flügelmutter 6 an das Betätigungsglied 5 angekoppelt (Fig. 1 und 2) ist. Fig. 7 illustrates the next operational step in which as in 5 the bowel loop 21 prepared and the staple magazine 2 with the front one End of the device body 1 is inserted. In the intestinal loop 21 is coaxial to the Staple magazine 2 introduced a defect 31 through which the pull rod 4 in the inner Bore 3 (Fig. 2) of the device body 1 is introduced and by means of the wing nut 6 is coupled to the actuator 5 (Figs. 1 and 2).

Fig. 8 zeigt den Zustand nach dem nächsten Verfahrensschritt, bei dem die Zugstange 4 durch Betätigung des Betätigungsgliedes 5 völlig eingezogen und somit die Gegendruckplatte 8 gegen das Klammermagazin 2 gepreßt ist, so daß die Klammerung erfolgt. Durch das gleichzeitig innerhalb des Klammermagazins 2 vorhandene ringförmige Stanzmesser wird der innerhalb der ringförmigen Klammerung liegende Teil der Speiseröhre 27 bzw. der Wand der Darmschlinge 21 herausgestanzt, so daß das Klammernahtgerät herausgezogen werden kann und ein freier Durchgang von der Speiseröhre 27 zu dem Darm 20 geschaffen ist. Fig. 8 shows the state after the next method step in which the pull rod 4 is completely retracted by actuating the actuator 5 and thus the counter pressure plate 8 is pressed against the staple magazine 2, so that the brackets take place. By the same present within the staple magazine 2 The ring-shaped punching knife is the one inside the ring-shaped brackets Part of the esophagus 27 or the wall of the intestinal loop 21 punched out so that the stapler can be pulled out and there is free passage from the Esophagus 27 to the intestine 20 is created.
