Nähvorrichtung Sewing device
B e s c h r e i b u nB e s c h r e i b u n
Technisches GebietTechnical field
Die Erfindung bezieht sich auf eine Nähvorrichtung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a sewing device according to the preamble of claim 1.
Stand der TechnikState of the art
Das Anlegen von Nähten stellt gerade in der minimal inva¬ siven Chirurgie ein großes Problem dar. Zwar sind bereits Instrumente vorgeschlagen worden, die dem Chirurgen die Ausführung der Nähte erleichtern sollen, die bekannten Instrumente weisen jedoch die verschiedensten Nachteile auf:Seaming is a major problem, particularly in minimally invasive surgery. Although instruments have already been proposed to make it easier for the surgeon to perform the sutures, the known instruments have the most diverse disadvantages:
So sind Instrumente vorgeschlagen worden, die in Art einer Zange aufgebaut sind. Die Nähnadel wird in das Zangenmaul eingeklemmt und zusammen mit einem Nähfaden beispielsweise in die Bauchhöhle eingeführt. Nach Durchstechen beider Wundränder mit der Nähnadel wird diese wieder mitsamt dem Faden aus dem Bauch herausgezogen. Danach wird ein Knoten außerhalb vom Körper gefertigt, der mit Hilfe eines Kno¬ tenschiebers bis zum Gewebe hin verschoben wird.For example, instruments have been proposed that are designed like pliers. The sewing needle is clamped into the forceps mouth and inserted into the abdominal cavity, for example, together with a sewing thread. After piercing both wound edges with the sewing needle, it is pulled out of the abdomen together with the thread. Then a knot is made outside of the body, which is moved to the tissue with the help of a knot pusher.
Diese Art der Wundnahtherstellung erfordert eine große Übung des Chirurgen. Außerdem ist es nachteilig, daß z.B. bei einer Knopfnaht der Vorgang sehr häufig wiederholt werden muß, und damit sehr zeitaufwendig ist. Andere Vorschläge sehen eine magnetische Fixierung der Nähnadel vor. Diese magnetische Fixierung ist allerdings sehr störungsanfällig.This type of suturing requires a great deal of practice from the surgeon. It is also disadvantageous that, for example, the process has to be repeated very often in the case of a button seam, and is therefore very time-consuming. Other proposals provide for magnetic fixation of the sewing needle. However, this magnetic fixation is very susceptible to failure.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Nähvorrich¬ tung für medizinische Anwendungen anzugeben, mit der auch ohne große Übung menschliches und/oder tierisches Gewebe in kurzer Zeit einfach und störungsunanfällig genäht wer¬ den kann.The invention is based on the object of specifying a sewing device for medical applications, with which human and / or animal tissue can be sewn in a short time easily and without interference, even without great practice.
Eine erfiπdungsgemäße Lösung dieser Aufgabe ist im Patent¬ anspruch 1 angegeben. Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.An inventive solution to this problem is specified in claim 1. Developments of the invention are the subject of the dependent claims.
Die erfindungsgemäße Nähvorrichtung weist wenigstens eine Schale auf, die mindestens eine Nähnadel aufnehmen und führen kann, und die einen Stab bzw. eine Stange teilweise umgreift.The sewing device according to the invention has at least one shell which can receive and guide at least one sewing needle and which partially encompasses a rod or a rod.
Durch eine Drehung der wenigstens einen Schale kann die Nähnadel durch das zu vernähende Gewebe geschoben werden. Dabei kann die Schale zusammen mit dem Stab bzw. der Stan¬ ge gedreht werden. Besonders bevorzugt ist es jedoch, wenn die Schale(n) um den Stab wenigstens längs eines Umfang¬ segments drehbar ist (sind) . In diesem Falle kann der Stab nicht drehbar ausgeführt sein.By rotating the at least one shell, the sewing needle can be pushed through the tissue to be sewn. The shell can be rotated together with the rod or the rod. However, it is particularly preferred if the shell (s) can be rotated around the rod at least along a circumferential segment. In this case the rod cannot be made rotatable.
Bei einer bevorzugten Weiterbildung der Erfindung umgeben wenigstens zwei Schalen den Stab. Um die Nähnadel zusammen mit dem an ihr befestigten Nähfaden durch das Gewebe "hin¬ durchzuschieben", wird die Nähnadel von der einen Schale nach Durchtritt durch das zu nähende Gewebe an die andere Schale übergeben wird. Durch die weitere Drehung der ande- ren Schale wird die Nähnadel weiter bewegt, so daß eine komplette Naht angelegt werden kann. Um den Faden mehrfach durch das Gewebe hindurchzuziehen, kann die Nähnadel wieder von der ersten Schale "übernommen" werden, so daß die Nähnadel in gleicher Weise wie vorstehend beschrieben erneut durch das Gewebe hindurchgeschoben werden kann. Der Längsversatz der Nähte in Längsrichtung kann dabei durch eine Verschiebung der Nähvorrichtung als Einheit oder durch eine Verschiebung der Schale(n) relativ zu dem Stab bzw. der Stange der Nähvorrichtung erzeugt werden.In a preferred development of the invention, at least two shells surround the rod. In order to "push" the sewing needle together with the sewing thread attached to it through the tissue, the sewing needle is transferred from one shell to the other shell after it has passed through the tissue to be sewn. By further turning the other Ren shell is moved the sewing needle further, so that a complete seam can be created. In order to pull the thread through the fabric several times, the sewing needle can again be "taken over" by the first shell, so that the sewing needle can be pushed through the fabric again in the same way as described above. The longitudinal offset of the seams in the longitudinal direction can be generated by a displacement of the sewing device as a unit or by a displacement of the shell (s) relative to the rod or the rod of the sewing device.
Damit kan'n beispielsweise in der minimal invasiven Chirur¬ gie eine Naht im Körper des Patienten wie folgt erstellt werden:Thus kan 'n example in minimally invasive Chirur¬ gie a seam in the body of the patient as to create the following:
Die Nähvorrichtung wird beispielsweise in die Bauchhöhle des Patienten eingeführt und in die Nähe der zu nähenden Wundränder gebracht. Die Wundränder werden nun mittels einer Pinzette oder einem zangenartigten Instrument zusam¬ mengedrückt, w#hrend die Naht genäht wird. Es sind nunmehr nur noch zwei Knoten erforderlich, die entweder durch das Nähgerät geknotet werden können oder aber - wie herkömm¬ lich üblich - außerhalb des Körpers vom Patienten geknotet und dann mit einem Knotenschieber bis zum Gewebe hin ver¬ schoben werden.The sewing device is inserted, for example, into the patient's abdominal cavity and brought close to the wound edges to be sewn. The edges of the wound are then pressed together using tweezers or a forceps-like instrument while the seam is being sewn. Only two knots are now required, which can either be knotted by the sewing device or, as is customary, knotted outside the body by the patient and then pushed to the tissue with a knot pusher.
Besonders vorteilhaft ist es, die Nähnadeln in der bzw. den um den Stab rotierenden Schalen mechanisch zu fixieren bzw. freizugeben. Diese Fixierung und Freigabe kann bei¬ spielsweise durch Stössel erfolgen, die sich in Kanälen befinden, die die Kanäle, in der sich die Nähnadel befin¬ det, kreuzen. Der Nähvorgang erfolgt dadurch rein mecha¬ nisch und frei von Störungen, wie sie z.B. bei einer Näh¬ nadelfixierung mit Magneteinwirkung auftreten könnten. Die Bewegung der beweglichen Teile kann durch Motoren, wie z.B. Servomotoren oder Schrittmotoren erfolgen. Es ist aber auch möglich, diese Bewegung mechanisch durchzuführen oder z.B. mit Bimetall oder Materialien mit einem "Formge¬ dächtnis" .It is particularly advantageous to mechanically fix or release the sewing needles in the shell or shells rotating around the rod. This fixation and release can take place, for example, by means of plungers which are located in channels which cross the channels in which the sewing needle is located. As a result, the sewing process takes place purely mechanically and free of disturbances, such as could occur, for example, in the case of a sewing needle fixation with magnetic action. The moving parts can be moved by motors, such as servomotors or stepper motors. However, it is also possible to carry out this movement mechanically or, for example, with bimetal or materials with a "shape memory".
Die Motoren können dabei mittels Relais oder durch eine elektronische Steuereinheit gesteuert werden.The motors can be controlled by relays or by an electronic control unit.
Die erfindungsgemäße Vorrichtung hat den weiteren Vorteil, daß sie cnne weiteres so aufgebaut werden kann, daß sämt¬ liche Teile der Vorrichtung einzeln und/oder zusammen desinfiziert werden können.The device according to the invention has the further advantage that it can be constructed in such a way that all parts of the device can be disinfected individually and / or together.

Darstellung von AusführungsbeispielenRepresentation of exemplary embodiments
In den Figuren 1 bis 5 ist ein erstes Ausführungsbeispiel einer erfindungsgemäßen Nähvorrichtung dargestellt. Die Nähvorrichtung für medizinische Anwendungen und insbeson¬ dere zum Nähen von Gewebe in der minimal invasiven Chirur¬ gie weist zwei Schalen 4a und 4b auf, die einen Stab bzw. eine Stange 3 teilweise, d.h. auf einem Kreissektor von - bei dem gezeigten Ausführungsbeispiel - 90° umgeben (s. Fig. 2) . Jede der beiden Schalen ist so ausgebildet, daß sie eine - bei dem gezeigten Ausführungsbeispiel kreisför¬ mig gebogene - Nähnadel 6 mit daran befestigten Faden aufnehmen und führen kann. Zum Dreh-Antrieb der Schalen 4a und 4b sind die in Fig. 1 schematisch dargestellten Moto¬ ren 1 und 2 vorgesehen. Die Motoren 1 und 2 stehen mit den Enden der Schalen 4a und 4b über Zahnradsegmente 11 (Fig. 4) in Wirkverbindung.1 to 5 show a first embodiment of a sewing device according to the invention. The sewing device for medical applications and in particular for sewing tissue in minimally invasive surgery has two shells 4a and 4b, which partially or rod 3, i.e. on a circle sector of - in the exemplary embodiment shown - surrounded by 90 ° (see FIG. 2). Each of the two shells is designed in such a way that it can receive and guide a sewing needle 6 with a thread attached to it - in the exemplary embodiment shown circularly curved. The motors 1 and 2 shown schematically in FIG. 1 are provided for rotating the shells 4a and 4b. The motors 1 and 2 are operatively connected to the ends of the shells 4a and 4b via gear segments 11 (FIG. 4).
In Fig. 2 befindet sich die Nähnadel 6 in der rechten Schale 4a. In diesem Zustand ist die Nähvorrichtung be¬ reit, die Nähnadel 6 durch das zu vernähende nicht gezeig¬ te Gewebe zu schieben, das sich im oberen Bereich der Nähvorrichtung zwischen den beiden Schalen 4 a und 4b befindet.In Fig. 2 the sewing needle 6 is in the right shell 4a. In this state, the sewing device is ready to push the sewing needle 6 through the tissue, not shown, to be sewn, which is located in the upper area of the sewing device between the two shells 4 a and 4 b.
Nach dieser kurzen Beschreibung des grundsätzlichen Auf- baus der erfindungsgemäßen Nähvorrichtung soll im folgen- den zunächst deren Funktionsweise beschrieben werden, bevor auf weitere Einzelheiten des Aufbaus eingegangen wird.After this brief description of the basic structure of the sewing device according to the invention, the following which first describe how they work before going into further details of the structure.
Nach dem Einschalten der Motoren 1 und 2 rotieren die Schalen 4a und 4b um den Stab 3 gegeneinander aufeinander zu. Die Nadel 6 befindet sich in einem Kanal 8a der Schale 4a und ist über eine Nocke 12a und einen Stößel 9a in diesem Kanal fixiert (Fig. 3) . Zum Nähen dieses Gewebes bewegt sich nun die Scheibe 4a mit der Nadel 6 entgegen dem Uhrzeigersinn zur Scheibe 4b hin, die im Uhrzeigersinn rotiert. "Dadurch wird die Nadel 6 durch das Gewebe hin¬ durch geschoben und in einen Kanal 8b in der Schale 4b eingeführt. Kurz bevor sich die Scheiben treffen, gibt der Stößel 9a die Nadel frei und ein Stößel 9b fixiert über eine Nocke 12b die Nadel im Kanal 8b. Gleichzeitig wird die Bewegungsrichtung der Scheiben umgekehrt. Dadurch wird die Nadel vollständig aus dem Gewebe herausgezogen, wä¬ hrend der Nähfaden durch das Gewebe hindurch gezogen wird.After the motors 1 and 2 have been switched on, the shells 4a and 4b rotate around the rod 3 towards one another. The needle 6 is located in a channel 8a of the shell 4a and is fixed in this channel via a cam 12a and a plunger 9a (FIG. 3). To sew this fabric, the disc 4a now moves counterclockwise with the needle 6 towards the disc 4b, which rotates clockwise. "As a result, the needle 6 is pushed through the tissue and introduced into a channel 8b in the shell 4b. Shortly before the disks meet, the plunger 9a releases the needle and a plunger 9b fixes the needle in via a cam 12b Channel 8b at the same time the direction of movement of the disks is reversed, pulling the needle completely out of the fabric while the sewing thread is being pulled through the fabric.
Auf der entgegengesetzten - d.h. auf der in Fig. 2 unteren - Seite wird die Nadel wieder vom Kanal 8b der Schale 4b in den Kanal 8a der Schale 4a übergeben. Dieses kann durch eine geeignete Wahl der Länge der Nadel sofort geschehen oder aber falls die Nadel etwas kürzer ist, durch mehrma¬ liges Nachsetzen. Es ist aber wichtig festzuhalten, daß die Nadel 6 bei diesem Ausführungsbeispiel der Nähvorrich¬ tung grundsätzlich länger als die Kanäle 8a und 8b ist.On the opposite - i.e. on the lower side in FIG. 2, the needle is again transferred from the channel 8b of the shell 4b into the channel 8a of the shell 4a. This can be done immediately by a suitable choice of the length of the needle or, if the needle is somewhat shorter, by repeated repositioning. However, it is important to note that the needle 6 in this embodiment of the sewing device is fundamentally longer than the channels 8a and 8b.
Unter dem Spiel der Stößel 9a und 9b und der auf die Stößel einwirkenden Nocken 12a und 12b oder Rotation der Schalen um den Stab 3 kann somit eine fortlaufende Naht erfolgen. Die Rotation der die Nocken tragenden Scheibe 13 wird z.B. durch den dritten Motor 10 bewirkt. Der zeit- liehe Ablauf der Elemente kann z.B. durch Relais oder eine elektronische Steuereinheit gesteuert werden.With the play of the plungers 9a and 9b and the cams 12a and 12b acting on the plungers or rotation of the shells around the rod 3, a continuous seam can thus be made. The rotation of the disk 13 carrying the cams is caused, for example, by the third motor 10. Currently- The sequence of the elements can be controlled, for example, by relays or an electronic control unit.
Es ist auch möglich, bei diesem Ausführungsbeispiel der Erfindung den Motor 10 wegzulassen und die Nocken bzw. die damit verbundenen Stößel über die Motoren 1 und 2 zu steuern.It is also possible to omit the motor 10 in this exemplary embodiment of the invention and to control the cams or the tappets connected thereto via the motors 1 and 2.
Bei einer weiteren Ausführungsform wird die Übergabe der Nadel derart ausgeführt, daß sie im Zeitpunkt der Übergabe von der einen Schale zur nächsten Schale durchrutscht. Dazu ist es erforderlich, daß die Schalen sich auf unter¬ schiedlichen Ebenen bewegen. Die Durchrutschbewegung kann in diesem Falle auch z.B. wieder durch Stößel bzw. Nocken geschehen.In a further embodiment, the transfer of the needle is carried out such that it slips from one shell to the next shell at the time of transfer. For this it is necessary that the shells move on different levels. In this case, the slipping movement can also e.g. done again by tappets or cams.
In den Fig. 6 und 7 ist ein weiteres Ausführungsbeispiel der Erfindung dargestellt. Eine direkt oder indirekt mit der Welle eines Motors verbundene Scheibe 4c kann die Nähnadel 6 aufnehmen. Im ersten Schritt ist die Nadel 6 im Kanal 8c fixiert, während die Scheibe sich entgegen dem Uhrzeigersinn bewegt, wobei die Nadel einen Stich aus¬ führt. Die Nadel wird nach Einführen in eine Nadelhalte- rungsvorrichtung dort fixiert und von der Scheibe 4c ge¬ löst. Die Scheibe bewegt sich nun im Uhrzeigersinn und zwar so lange, bis die Scheibe an die Nadelhalterungsvor- richtung 4d gelangt. Dort wird die Nadel wieder übernommen und ein Stück entgegen dem Uhrzeigersinn verfahren. Nach einem erneuten Nachgreifen kann ein weiterer Stich ausge¬ führt werden.6 and 7 a further embodiment of the invention is shown. A disc 4c connected directly or indirectly to the shaft of a motor can accommodate the sewing needle 6. In the first step, the needle 6 is fixed in the channel 8c while the disk is moving counterclockwise, the needle making a stitch. After insertion into a needle holder device, the needle is fixed there and released from the disk 4c. The disk now moves clockwise until the disk reaches the needle holder 4d. There the needle is taken over again and moved a little bit counterclockwise. After re-reaching, another stitch can be carried out.
Die Fixierung der Nadel 6 im Kanal 8d der Nadelhalterungs- vorrichtung 4d kann in diesem Falle auch wieder mechanisch durch Stößel geschehen. Der Zahnkranz der beweglichen Scheibe 4c kann z.B. auch statt am Rand innen liegen. Dadurch wird es möglich, einen der Motoren zentral anzu¬ bringen.In this case, the fixation of the needle 6 in the channel 8d of the needle holder device 4d can also be done mechanically by means of a plunger. The ring gear of the movable Disk 4c can, for example, also be inside instead of at the edge. This makes it possible to attach one of the motors centrally.
Es ist denkbar, die erfindungsgemäße Vorrichtung mit mehr oder weniger Motoren auszuführen und auch die Motoren anders als in den Figuren angegeben, anzuordnen. Insbeson¬ dere ist es denkbar, die Motoren am anderen Ende der Näh¬ vorrichtung, also z.B. im Griffbereich, anzubringen und über geeignete Antriebe 3 und Gelenke die beweglichen Teile des Kopfes der Nähvorrichtung zu verfahren. Sollte eine exzentrische Anordnung der Bauteile der Nähvorrich¬ tung gewünscht sein, so ist dieses auch möglich.It is conceivable to design the device according to the invention with more or fewer motors and also to arrange the motors differently than indicated in the figures. In particular, it is conceivable to mount the motors at the other end of the sewing device, e.g. in the grip area, to attach and to move the moving parts of the head of the sewing device via suitable drives 3 and joints. If an eccentric arrangement of the components of the sewing device is desired, this is also possible.
Die Anordnung der Teile der Nähvorrichtung ist nicht auf Kreisform beschränkt, vielmehr ist z.B. auch ein ellipso- ide Gestaltung möglich. Dabei ist zu beachten, daß die Nähnadel elastisch ausgeführt werden muß.The arrangement of the parts of the sewing device is not limited to a circular shape, but is e.g. an ellipsoidal design is also possible. It should be noted that the sewing needle must be elastic.
Die Steuerung der beweglichen Bauteile der vorgestellten erfindungsgemäßen Nähgeräte erfolgt zweckmäßigerweise mit Relais. Es ist aber auch möglich, eine Computersteuerung einzusetzen. The control of the movable components of the presented sewing devices according to the invention is advantageously carried out with relays. However, it is also possible to use a computer control.
