Device for protecting the rectal anastomosis
First Claim
1. A device for protecting rectal anastomosis, the device comprising:
- (a) a cylinder- or tube-shaped head filter which is slanted toward an outer head portion of a main tube and can be inflated by pressure, wherein the outer circumferential surface of the head filter is composed of micro-villi or micro-corrugations for preventing the inflow of the intestinal contents into an anastomotic area; and
(b) a main tube which can be inserted inside the intestinal canal and includes a main duct, through which the intestinal contents pass, and a first auxiliary duct which transfers pressure for inflating the head filter.

Abstract
The present invention relates to a device for protecting rectal anastomosis. The device of the present invention is a double type leakage prevention system composed of micro-villi of a head filter and a triple lumen catheter, and thus minimizes contamination of the anastomotic area from intestinal contents, thereby enabling successful healing of the rectal anastomotic area. The device of the present invention has a main tube with side holes, and thus the intestinal contents, even when passing through the head filter, are sucked into the main tube through the side holes, so that the intestinal contents can be effectively drained while being diverted from the anastomotic area. The device of the present invention is inserted through the anus after surgery and thus involves less risk of additional complications due to the installation of the device, and has advantages of low manufacturing costs due to the simplification of the structure and convenient use and handling. Furthermore, the device of the present invention serves as an existing support for protecting anastomosis, thereby alleviating patient discomfort due to anastomotic leakage.
