Abstract

A device for introducing an endoscope or a surgical tool into body cavities with a feed for a flushing medium and an extractor for said flushing medium, which permits as versatile as possible an application of the endoscope or tool and maintains a higher pressure in the interior of the body as compared with the environment. The device includes a sluice, insertable into the body cavity from outside. The sluice has a cylindrical stem along whose inner wall extend two separate longitudinal grooves which have openings at their ends which pass through the wall of the stem. The openings outside the body are connected to the feed and the extractor for the flushing medium. A cylindrical endoscope or tool is inserted into the device with its outer wall tightly contacting the inner wall of the stem. The outer wall of the endoscope or tool, together with the longitudinal grooves of the stem, form sealed channels for the flushing medium.
