DEVICE FOR TAMPONADE SEALING PROTECTION OF SURGICAL SUTURES AND WOUNDS, IN PARTICULAR OF END-TO-END ANASTOMOSES OF THE RECTUM

摘要

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.
