The present invention provides a surgical suction cannula capable of sucking a liquid component such as a small amount of blood while keeping an ability to suck a large clot such as a blood clot and to sweep them. The present invention relates to a surgical suction cannula, including: a tip opening capable of sucking a clot such as a blood clot and a suction structure in the front of the tip opening. Due to the suction structure, the liquid component such as a small amount of blood can be sucked. Further, even when the tip opening is pressed against the vicinity of an organ, the suction structure interposed between a suction port and a surface of the organ prevents choke between the organ and the cannula or damage to the organ due to choke by suction. In addition, in a case of bleeding in a surgical site, the blood is sucked while controlling the bleeding by pressurizing a bleeding site, to thereby provide a view enabling a hemostatic site to be treated.
