Problems solved by technology

[0004] Although the above-mentioned hemostatic stent for heart and great vessel surgery can open the built-in air tank to inflate the elastic bag by pressing the a-end of the spool, so that the elastic bag can be inflated to stop bleeding, reduce the excessively connected pipes of the hemostatic stent, and increase the hemostatic efficiency. But still there are following deficiencies: when the pressure of the elastic sac is too high, the gas filling amount in the elastic sac cannot be automatically reduced, and the blood vessels are easily broken, which is not conducive to the operation, and the gas requires too much airtightness. Gas entering the blood can cause vascular embolism, which will affect the normal blood and oxygen supply of tissues and organs, and can cause acute infarction in severe cases

Abstract

The invention relates to the technical field of cardiac aorta surgeries and particularly relates to a hemostatic stent for a cardiac aorta surgery. The hemostatic stent comprises a shell I, wherein two sides of the shell I are spirally connected with a shell II and a shell III separately, a telescopic rod is arranged in the shell III, a telescopic hose is arranged in the telescopic rod, a sealing ring II is fixedly connected to the bottom wall of the telescopic rod, one end of the telescopic hose communicates with the sealing ring II, and a medicine sprayer used for slowing down blood coagulation is arranged on the side wall of the shell III. According to the hemostatic stent for the cardiac aorta surgery, and a rubber disc is extruded through normal saline, a binding post I can be connected with a connector lug I, so that an electromagnet I is powered on, then, a conductive ball can be separated from a wiring base, a motor can stop working, the situation that blood vessels of a patient are burst due to the fact that pressure in a sealing ring I and the sealing ring II is too high is avoided, and the safety of the patient is facilitated; and meanwhile, the sealing ring I is matched with the sealing ring II, so that blood can be further intercepted, and medical staff can conduct an operation conveniently.

Description

technical field [0001] The invention relates to the technical field of heart and great vessel surgery, in particular to a hemostatic stent for heart and great vessel surgery. Background technique [0002] The heart is the most important organ in the body of a vertebrate. Its main function is to provide pressure for blood flow and run the blood to all parts of the body. The function of the heart is to promote blood flow and provide sufficient blood flow to organs and tissues to supply oxygen and various nutrients, and take away the end products of metabolism (such as carbon dioxide, inorganic salts, urea and uric acid, etc.), so that cells can maintain normal metabolism and function. Large vessel surgery is aimed at aortic trunk diseases (Marfan syndrome syndrome, aortic dissection aneurysm, etc.) surgical treatment method, has been a huge, complex, difficult, high-risk surgery in cardiovascular surgery, large vessel surgery has high risk, high surgical mortality, long operat...
