Problems solved by technology

However, that case concerns a generally passive arrangement in which the pressure inside the balloon is reduced compared to a silicone-based balloon; Tightly placed in the colon, based on the peristalsis there, it is still necessary to choose a pressure that is usually too high, which can lead to damage of the highly sensitive tissue after a resection intervention

Embodiment Construction

[0031] figure 1 Shown is a device 1 for protective packing of an anastomotic intestinal section connected end-to-end, wherein the anastomosis is established by surgical suturing or surgical clipping creating a lumen or by anastomosis of the intestinal segments to be connected, The device consists of a catheter part 2, an extracorporeal conditioning unit 3 and a container 4 for leading out and collecting feces.

[0032] The catheter part 2 remains in the body of the patient throughout the time of use of the device. In the embodiment shown, the catheter part consists of a dumbbell-shaped balloon element 5 fitted with a flexibly bendable hose element 6 following the twist of the rectosigmoid colon, said hose element being at the corresponding end of the intestinal tract. Under force, or also under a corresponding group movement of the body or abdomen, it collapses elastically and under the action of a declining force elastically recovers it by producing a given corresponding con...

Abstract

The invention is directed to a device (1) for sealingly protective and at the same time stool-discharging tamponade of a circular anastomosis of two ends of the large intestine, as occur for example in the surgical resection of a rectal carcinoma, wherein a thin-walled balloon body (5) is placed in the region of the anastomosis, and the balloon (5), providing a tamponade, is filled with a filling medium in such a way that the lowest possible pressure necessary for the sealing tamponade of the anastomosed portion of the intestine can be maintained continuously, and, even in the event of a peristaltic contraction of the rectosigmoid colon, the pressure predefined by the user is maintained as constant as possible, wherein sufficiently high volumetric flows of the pressurizing medium supplied to and removed from the balloon (5) are achieved, such that the sealing contact between the balloon (5) and the intestinal wall is maintained in all segments of the balloon body in the course of a peristaltic contraction wave running from the sigmoid to the anus.

Description

technical field [0001] The present invention relates to a device and a method for sealing the tampon protection of the surgically formed annular anastomosis between the ostium and the ostium of the large intestine, in particular the rectum or sigmoid colon, or otherwise in this portion of the intestine The resulting suture or lesion simultaneously has the function of exporting feces through the anastomotic or injured or surgically or otherwise intervened segment of bowel and subsequently passing the feces through the anal sphincter. Background technique [0002] During resection of tumors in the rectal and sigmoid field, circular sutures are usually formed to connect the ostium of the intestine cut during the resection "end-to-end" with the anti-oste end. In most cases, the anastomosis is performed by means of metal clips arranged in a ring, which connect the two bowel ends and recreate a coherent bowel lumen. Clipping is performed by means of an instrument (so-called stapl...
