Abstract

A suture ring (1) assembled of a soft inner silicon layer (4) and two reinforced outer silicon layers (5, 6) and provided with an upper and a lower Dacron (RTM) cover (7) is stitched to the heart, the tube (2) is inserted and immediately sealed by a lip positioned at the inner surface of the ring (1). The tube (2) can be rotated until it is secured in its ideal final position by fastening the ring (1) to the heart.

Description

Die Erfindung betrifft eine Vorrichtung zur Verbindung eines Hohlorgans mit einer Kanüle.The invention relates to a device for connection of a hollow organ with a cannula.

Die Vorrichtung, ein Nahtring 1, verhindert eine Verformung der Anastomosenstelle und ermöglicht es, zunächst die passende Position (bzgl. der Rotation) einer Kanüle 2 zu ermitteln, bevor die Kanüle 2 mit einer Naht 9 fixiert wird.The device, a suture ring 1 , prevents deformation of the anastomosis site and makes it possible to first determine the appropriate position (with respect to the rotation) of a cannula 2 before the cannula 2 is fixed with a seam 9 .

Der Nahtring besteht aus einem Silikonkern, der aus einer inneren Schicht 4 aus unvertsärktem Silikon und beidseitig anliegenden Schichten 5, 6 aus verstärktem Silikon aufgebaut ist. Sowohl auf der Ober- als auch auf der Unterseite ist ein Dacronvelourgewebe aufgeklebt. Er ist also fünfschichtig aufgebaut.The seam ring consists of a silicone core, which is made up of an inner layer 4 made of unreinforced silicone and layers 5 , 6 lying on both sides made of reinforced silicone. A Dacron velor fabric is glued to both the top and bottom. So it has five layers.

Die mittlere Schicht (Silikon) 4 hat am inneren Radius eine Lippe 8, so daß der innere Durchmesser des Nahtrings 1 in der Höhe der Lippe geringfügig kleiner ist als der Außendurchmesser der Einlaßkanülenspitze 13.The middle layer (silicone) 4 has a lip 8 on the inner radius, so that the inner diameter of the seam ring 1 at the height of the lip is slightly smaller than the outer diameter of the inlet cannula tip 13 .

Dies bietet folgenden Vorteil: Ist der Nahtring 1 aufgebracht und befestigt, wird die Spitze 13 der Kanüle durch die Öffnung des Nahtrings hindurchgeschoben. Bereits jetzt kommt durch den Kontakt der Silikonlippe 8 mit der Außenseite der Einlaßkanülenspitze 13 eine Dichtigkeit zustande und es besteht gleichzeitig die Option, die Kanüle im Nahtring 1 zu verdrehen, bis die optimale Position gefunden ist. Erst dann wird der Nahtring 1 mit dem Nahtflansch 14 durch Naht 9 verbunden und fixiert. This offers the following advantage: If the suture ring 1 is applied and fastened, the tip 13 of the cannula is pushed through the opening of the suture ring. A tightness is already achieved by the contact of the silicone lip 8 with the outside of the inlet cannula tip 13 and there is at the same time the option of rotating the cannula in the suture ring 1 until the optimal position is found. Only then is the seam ring 1 connected and fixed to the seam flange 14 by seam 9 .
