Description

Snap-together button with transfer channel for insertion between the pieces of intestine to be connected during intestinal operations. For intestinal operations When connecting two pieces of intestine, it becomes a continuous intestinal canal between the pieces of intestine are inserted into a button that is later excreted, which consists of two pluggable parts to be inserted opposite one another in the two pieces of intestine exists and when plugged together forms a transfer channel through which the crossover of the intestinal content ## from one piece of intestine to the other during the healing process is ensured.

These buttons, named after the inventor M li r p h y , also have the disadvantage that from the time the button parts are inserted into the intestinal wall until the button parts are plugged together, intestinal contents easily escape through the transfer nozzle. This jeopardizes the asepsis of the operation.

The present invention only aims at this disadvantage as well to eliminate and thereby facilitate the insertion of such buttons in intestinal operations.

For this purpose, according to the invention, the transfer nozzles which are located in the two button parts and which slide into one another when the button parts are inserted are each kept closed by a layer which later automatically releases the transfer channel again.

This can be achieved in a number of ways. Thus, the two sealing layers can each consist of a mass that dissolves after the button is put together under the action of body heat or the intestinal juice or under the action of both.

The two sealing layers can each consist of a thin, easily puncturable or tearable material, e.g. B. from a thin parchment, paper, rubber o. The like. Skin, consist.

In this case, the piercing or tearing of one sealing membrane can easily be achieved when the button is put together by the two transfer stubs coming into one another by placing the sealing membrane of the outer stub in the path of the inner stub. In order to achieve an automatic piercing or tearing also of the second locking membrane when the button is plugged together, a separate piercing, cutting or tearing member is also provided. The same can be of various types and possibly also be circumvented by using a layer that dissolves under body heat or under the action of the intestinal contents instead of the second occlusive membrane , thus combining both main design options.

Such a button is shown in the drawing for the sake of clarity enlarged, shown by Figs. i to 4 in four different embodiments.

In the embodiment of Fig. I both of the transition piece s of the button part c and the Übefleitungsstutzen it of the knob portion d at any position, for. B. closed at the inner or outer ends by a plug or by a transverse wall o, which consists of a mass gradually dissolving under the action of body heat or the intestinal juice or under the action of both.

The resistance of this mass is chosen so that the locking effect not done before the button parts have been fully inserted and joined together.

In this way, the transfer nozzles of the button remain closed until the button is fully inserted. This prevents the contents of the intestines from escaping from the intestinal pieces a and b to be connected when the button is inserted and jeopardizing the asepsis of the operation.

The insertion of the button and the self-producing, expediently mutual connection of the two button parts takes place in an otherwise known manner.

In the illustrated by the Fig. 2 to 4 embodiments for Locked holding the transition piece and e it during insertion of the fastener parts per a thin tearing during mating of the knob parchment, paper, rubber o. Like. Skin g and 1 are used, of which one (g) is held, for example, by means of a small ring h on the outer transfer connector e, and when the button parts c and d are plugged together through the inner transfer connector n, which is pushed into the outer transfer connector e is cut up or simply pierced.

So that the other parchment, paper, rubber or similar skin 1 when putting together the button parts c and d itself- is actively destroyed, the execution forms according to Fig. 2 to 4, the following different take precautions: In the embodiment according to Fig. 2 and 3 receives the button part d outside the inner transfer connection n still one second (auxiliary) connection piece k, which is put the button together over the outer one Transfer supports e pushes. The second cap 1 is at both the embodiments above these auxiliary clip k stretched and is on this, z. B. by an inside (Fig. 2) or outside (Fig. 3) clamp ring to be applied held.. So that's in the same way as that Cap g in the way of the inner Transfer nozzle lies, the occlusive membrane chen 1 in the path of the external transition stutzens e " so that this also by inserting the button or cut it is pierced. In the embodiment (Fig. 2) has the inner transfer connection is resilient gen i that when mating the button into an internal thread of the external transfer intervene and thus one of the Murphy buttons, when put the two button parts between them self-producing, by turning Form the connection to be released again. The same connection is for example also in the embodiment according to Fig. i shown. In the embodiment (Fig. 3) are the resilient tongues i in contrast to the guide form according to Fig. 2 not on the inner transfer nozzle m, but an the auxiliary connection k arranged and grab accordingly not in an interior, but in an external thread of the transfer connection socket e. Common to Murphy buttons Liche resilient back, softenable clamping piece f can, as Fig. 1, 3 and 4 shows, either the outer transfer nozzle e or how Fig. 2 shows the inner transfer nozzle m and surround the auxiliary nozzle k . In the embodiment according to Fig. 4 is instead of an auxiliary nozzle for destruction of the sealing membrane in the way of the outer transfer nozzle c lying and of this when plugging the button can be pushed back or pushed back, given if sleeve-shaped ring p is provided, the slides on the inner transfer nozzle iv and so connected with the cap 1 is bound, # that he stuck the dull button through his retreat before the outside. Transfer nozzle to t> Tear brings. This can if necessary by a knife-edge design the covered edges of the inner overhang do, gs-sttitzens are supported.
