Abstract

The system for anastomosing arteries and veins involves a connecting piece made from a body friendly material which is hollow. At each end of the connecting piece there is a cone shaped section. The connecting piece is introduced into the inner lumen of the blood vessel such that the inner side of the vessel wall is distended slightly due to the cone shaped sections. By means of a ring which is pushed over the vessel around the connecting piece it is fixed in position in a fluid tight manner whilst avoiding strangulation of the vessel. The ring is held in place by clamps formed on the connecting piece.

Description

In der Chirurgie gibt es bei der blutdichten Verbindung (Anastomosierung) von Blutgefäßen untereinander, bzw. mit künstlichen Implantaten wie Dacron oder Gore-Tex, zur Naht von Hand noch keine Alternative. Solche Anastomosen sind in der Gefäßchirurgie ständig anzufertigen (z. B. Bypass) und stellen einen wesentlichen Zeitfaktor in der Operationsdauer dar. Auch in der Unfall­ chirurgie werden gelegentlich solche Anastomosen unter zum Teil erheblichem Zeitdruck erforderlich. - Das im Folgenden beschriebene System gestattet eine sichere Anastomosierung in wenigen Augenblicken mit 3 relativ einfach zu produzierenden Einzelteilen.In surgery there is a blood-tight connection (anastomosis) of blood vessels with one another, or with artificial implants such as Dacron or Gore-Tex, no alternative to hand sewing. Such anastomoses are to be made and placed continuously in vascular surgery (e.g. bypass) an essential time factor in the duration of the operation. Also in the accident Surgery sometimes causes such anastomoses to be considerable Time pressure required. - The system described below is permitted safe anastomosis in a few moments with 3 relatively easy individual parts to be produced.

Es handelt sich um eine aus Metall, Kunststoff oder anderem festen Material bestehende kreisrunde Scheibe von etwas größerem Durchmesser als das betref­ fende Blutgefäß und einer Dicke in der Größenordnung eines Millimeters mit einer zentralen, kreisrunden Durchlaßöffnung, die mit blutverträglichem Material (Gore-Tex, Dacron o. ä.) ausgekleidet ist. Die beiden kreisförmigen Oberflächen der Scheibe steigen zur zentralen Öffnung hin, in ähnlicher Form wie ein Hyperboloid an, so daß die Stärke der Scheibe zur zentralen Öffnung hin in Form einer konkaven Fläche zunimmt (beidseitig). - Siehe Fig. 1 -. An der bandförmigen Seitenfläche der Scheibe sind aus Federstahl oder ähn­ lich elastischem Material bestehende Haken befestigt, die beidseits über die Konkavflächen ragen und einen über die Zentralöffnung geschobenen Ring passender Größe festzuhalten vermögen. - Siehe Fig. 2+3 -. Dieser im Folgen­ den noch näher beschriebene Ring R ist in seiner Form der Scheibe dergestalt angepaßt, daß er mit leichtem Druck auf die Konkavfläche - im Folgenden F genannt - gedrückt wird, wobei die Haken in eine Nut einrasten und den An­ druck bewirken.It is a circular disc made of metal, plastic or other solid material, somewhat larger in diameter than the blood vessel in question and of a thickness of the order of a millimeter with a central, circular passage opening which is covered with blood-compatible material (Gore-Tex, Dacron or the like) is lined. The two circular surfaces of the disk rise towards the central opening, in a shape similar to a hyperboloid, so that the thickness of the disk increases towards the central opening in the form of a concave surface (on both sides). - See Fig. 1 -. On the band-shaped side surface of the disc are made of spring steel or similar Lich elastic material attached hooks that protrude on both sides over the concave surfaces and are able to hold a ring of suitable size pushed over the central opening. - See Fig. 2 + 3 -. This in the following the ring R described in more detail in its shape of the disc is adapted such that it is pressed with slight pressure on the concave surface - hereinafter referred to as F -, the hooks snap into a groove and cause the pressure to occur.

Wird nun eine solche, dem Blutgefäßdurchmesser angepaßte Scheibe in das Lumen des Blutgefäßes eingeführt, gleitet die elastische Gefäßwand unter leichter Aufweitung auf die Fläche F. Durch eine geeignete unidirektionale Mikrostrukturierung von F wird das Zurückgleiten erschwert. - Der zuvor auf das Blutgefäß aufgeschobene passende Ring R wird nun über das Blutgefäß auf die Scheibe aufgeschoben, wobei die Haken in die Nut einrasten und ihn festhalten. Dadurch wird die Gefäßinnenwand (Intima) mit leichtem Andruck auf der Fläche F festgehalten. Wird nun in gleicher Weise auf der anderen Seite der Scheibe ein natürliches oder synthetisches Gefäß angeschlossen, ist die Anastomose beendet. Now such a, adapted to the blood vessel diameter disc in the Inserted lumen of the blood vessel, the elastic vessel wall slides under easy expansion to the area F. By a suitable unidirectional Microstructuring of F makes it difficult to slide back. - The one before the matching ring R pushed onto the blood vessel is now placed over the blood vessel pushed onto the disc, the hooks snapping into the groove and him hold tight. This creates a slight pressure on the inner wall of the vessel (intima) held on the surface F. Will now be in the same way on the other Connected to the side of the disc a natural or synthetic vessel, the anastomosis has ended.  

Der Ring R ist auf seiner dem Blutgefäß anliegenden Seite weich, auf seiner den Haken anliegenden Seite, die die Nut trägt, hart, was entweder durch unterschiedliche Beschichtung oder Aufbau aus zwei unterschiedlichen Ma­ terialien erreicht wird. - Siehe Fig. 4. -. Die Blutdichtigkeit erfolgt durch den leichten Druck der Gefäßinnenseite (Intima) auf die Fläche F und kann durch Fibrinkleber unterstützt werden. Der Druck, den der Ring R auf die Gefäßwand ausübt, darf dabei nicht das Gewebe so stark quetschen, daß eine Nekrotisierung (Absterben) des Gewebes eintritt. - Ringe und Scheibe werden in feinabgestuften unterschiedlichen Größen hergestellt, so daß eine genaue Anpassung an das zu anastomosierende Blutgefäß erfolgen kann.The ring R is soft on its side lying against the blood vessel, hard on its side lying against the hook, which carries the groove, which is achieved either by different coating or construction from two different materials. - See Fig. 4. -. The blood tightness is achieved by the slight pressure of the inside of the vessel (intima) on the surface F and can be supported by fibrin glue. The pressure that the ring R exerts on the vessel wall must not squeeze the tissue so much that necrotization (death) of the tissue occurs. - Rings and disc are manufactured in finely graduated different sizes, so that an exact adaptation to the blood vessel to be anastomosed can be made.
