For example, in the course of radical operation of rectal cancer, before the intestinal canal at the far end of the tumor is cut off, the intestinal canal needs to be cleaned by anus enema, and the traditional method comprises the following steps: (I): the pre-cut upper edge is not blocked, and direct enema washing can cause washing liquid to pass through a tumor area, so that the risk of dropping tumor cells and planting proximal intestinal tracts can be caused, the tumor-free principle can not be achieved, and the risk of tumor intestinal tract planting and anastomotic stoma recurrence can be increased; and the content of the proximal intestinal canal continuously flows into the distal intestinal canal, so that the intestinal canal is difficult to be washed cleanly, the pollution of an anastomotic stoma is serious, and the risk of anastomotic leakage is increased. (II): the intestinal clamp is used for directly clamping the intestinal canal, and the intestinal clamp is limited in clamping force and difficult to last in the manner of clystering and cleaning the reserved intestinal canal, so that the risks of tumor intestinal canal implantation and anastomotic stoma recurrence are increased. (III): the hepatic portal occlusion band is knotted to occlude the intestinal canal, the risk of tumor intestinal canal implantation and anastomotic stoma recurrence is increased when the knot is too loose, and the risk of intestinal necrosis caused by insufficient blood supply at the intestinal canal occlusion part is increased when the knot is too tight; and the ligation mode often is difficult to reach the cross section, and the intestinal canal tissue at the ligation position forms folds, when using the cutting anastomat to cut the intestinal canal, easily makes the incisal edge uneven or forms the wedge incisal edge, leads to anastomosing the difficulty or anastomotic stoma tension increase, increases the risk that the anastomotic stoma leaks.
