The invention relates to a common carotid artery cannula for adjusting and distributing blood perfusion flow and application. The common carotid artery cannula comprises a cannula body at a blood supply end and is characterized by further comprising a T-shaped or Y-shaped structured extracorporeal circulation perfusion plastic tube with a proximal end tube and a distal end tube for dividing flow and pressure, wherein the extracorporeal circulation perfusion plastic tube is communicated with the cannula body and formed on an overall structure. An included angle is formed between the proximal end tube of the Y-shaped structured perfusion tube and the cannula body at the blood supply end to distribute or adjust the blood perfusion flow. The common carotid artery cannula is applied to whole-body arterial perfusion and deep hypothermic circulatory arrest selective cerebral perfusion during extracorporeal circulation of a common carotid artery, and overcomes the shortcomings of an existing artery cannula and method. Carotid artery occlusion time is short during intubation and extubation, and cerebral blood supply is almost not affected, so that cerebral complications and the pain of patients are decreased. Obviously, the common carotid artery cannula is convenient to operate, surgical time is greatly shortened, so that cerebral ischemic time is shortened, the success rate of an aortic arch surgery is increased, and the common carotid artery cannula has a wide clinical application value.
