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. In surgery, there are in the blood tight connection (anastomosis) of blood vessels with each other, or with artificial implants such as Dacron or Gore-Tex, the seam by hand no 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. Such anastomoses are constantly to customize in vascular surgery (z. B. bypass) and represent a significant time factor in the duration of operation. Also in trauma surgery occasionally such anastomoses under considerable time pressure part required. - Das im Folgenden beschriebene System gestattet eine sichere Anastomosierung in wenigen Augenblicken mit 3 relativ einfach zu produzierenden Einzelteilen. - The system described below allows a secure anastomosis in a few moments with three relatively easy to producing items.

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. It is a made of metal, plastic or other solid material circular disc of somewhat larger diameter than the Subject Author Fende blood vessel and a thickness on the order of a millimeter with a central, circular through opening, which (with blutverträglichem material Gore-Tex, Dacron o. ä.) is lined. 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). The two circular surfaces of the disk to rise to the central opening, in a similar way like a hyperboloid such that the thickness of the disc to the central opening to form a concave surface increases (on both sides). - Siehe Fig. 1 -. - See 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. At the band-shaped side surface of the disc of elastic material are made of spring steel or similarity attached Lich existing hooks on either side extend beyond the concave surfaces and are capable of retaining a slid over the central ring opening of appropriate size. - Siehe Fig. 2+3 -. - See Figure 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. This consequences in the ring R is described in more detail adapted in its shape of the disk such that it with a slight pressure on the concave surface - is pressed, wherein the snap hooks in a groove and cause the pressure to - hereinafter referred to as F.

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. Will be one which is adapted to the blood vessel diameter disc inserted into the lumen of the blood vessel, the elastic vessel wall slides under a slight widening of the area F. Through a suitable unidirectional microstructuring of F sliding back is difficult. - 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. - The previously pushed onto the blood vessel a suitable ring R will be pushed over the blood vessel to the disc, wherein the hooks engage in the groove and firmly hold it. Dadurch wird die Gefäßinnenwand (Intima) mit leichtem Andruck auf der Fläche F festgehalten. Thus the vascular inner wall (intima) is held with light pressure on the surface F. Wird nun in gleicher Weise auf der anderen Seite der Scheibe ein natürliches oder synthetisches Gefäß angeschlossen, ist die Anastomose beendet. Is now connected in the same way on the other side of the disc a natural or synthetic vessel, the anastomosis is completed.

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. The ring R is soft on its adjacent side of the blood vessel, on its hook adjacent side carrying the groove, hard, which is achieved either by different coating or structure from two different Ma terialien. - Siehe Fig. 4. -. - See Figure 4.. -. Die Blutdichtigkeit erfolgt durch den leichten Druck der Gefäßinnenseite (Intima) auf die Fläche F und kann durch Fibrinkleber unterstützt werden. The blood-tightness is effected by the slight pressure of the vessel inner side (the intima) to the surface F and can be supported by fibrin glue. 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. The pressure which the ring R exerts on the vessel wall can not squeeze the tissue so much thereby, that necrosis (death) of the fabric occurs. - Ringe und Scheibe werden in feinabgestuften unterschiedlichen Größen hergestellt, so daß eine genaue Anpassung an das zu anastomosierende Blutgefäß erfolgen kann. - rings and disc are manufactured in various sizes finely graded, so that an accurate adjustment to the anastomosing blood vessel can take place.
