Coronary arterial perfusion tube

The utility model discloses a coronary arterial perfusion tube. The coronary arterial perfusion tube is characterized by comprising a straight rod and a perfusion head, wherein the straight rod and the perfusion head are each of a hollow structure; the perfusion head comprises a connecting section and a perfusion section; the outer end of the connecting section is open; the sidewall of the perfusion section is evenly provided with perfusion holes; the two ends of the straight rod are open; one end of the straight rod is provided with a handheld part; the other end of the straight rod is in butt joint with a shaping bent pipe in a fixed mode; the free end of the shaping bent pipe is in threaded connection with the perfusion head. The coronary arterial perfusion tube is simple in structure; the bending angle of the perfusion head can be adjusted at will so that the perfusion head can adapt to different kinds of coronary perfusion; moreover, the extension length of the perfusion head can be spirally adjusted so that the perfusion head can adapt to perfusion of a small-opening coronary artery of a child, so the coronary arterial perfusion tube is convenient to use.
