The invention relates to an anastomat provided with a conveying passage. The anastomat comprises an anastomat body, an anvil device which is arranged at a front port of the anastomat body and the conveying passage which extends to the front side of the anvil device from the anastomat body. The invention aims at providing the anastomat provided with the conveying passage, and operation interference of the anastomat can be effectively reduced and an operation success rate can be improved. The anastomat provided by the invention has the advantages that by virtue of the conveying passage which extends to the front side of the anvil device, liquid, gas or apparatus can be conveyed to an operative site through the conveying passage, so as to be used for conducting such treatment as cleaning, dilation and the like on the operative site, or such liquid as blood water and the like in the operative site can be sucked away, so that operators can clearly observe situation of an anastomotic stoma and deal with situation of poor anastomosis timely; therefore, the occurrence rate of such complications as postoperative anastomotic fistula, bleeding and the like can be reduced.
