Background
The heart is one of the most important organs in the vertebrate body and has the primary function of providing pressure for blood flow to move the blood to various parts of the body. The heart functions to promote blood flow, provide sufficient blood flow to organs and tissues to supply oxygen and various nutrients, and remove metabolic end products (such as carbon dioxide, inorganic salts, urea, uric acid, etc.), so that cells maintain normal metabolism and function. In heart major vascular surgery, it is often necessary to occlude a section of a blood vessel so that the adjacent vessel to the site of the occlusion can be opened for the surgical procedure. The existing occlusion methods are mainly performed using aortic clamps. However, the great cardiac vascular surgery usually requires a long operation time, and if the aorta is clamped by the aortic clamp for a long time for blocking the blood flow, certain damage can be caused to the outer wall of the aorta. Therefore, the aortic clamp needs to be loosened at regular time intervals in the operation process, the opening of the aortic clamp is loosened, blood flows out of the aorta, the blood loss in the operation is increased, and the operation risk is increased. And after the aortic forceps are loosened, a large amount of blood can be gushed into the operation field to shield the operation field, so that blood sucking operation is required, the operation is complicated, the operation time is prolonged, and the operation risk is further increased.
