Abstract
Abstract A device for irrigating the intestines that can be employed during surgery with an irrigating cannula for introducing a rinse and with a drain. To ensure irrigation during surgery of a section of intestine of any diameter upstream of the stenosis while avoiding any contamination of the operating field, the drain consists of an adapter connected germ-proof to a hose and of a plastic fastener securing the intestine to the adapter.
