Problems solved by technology

[0003] In order to make up for the deficiencies in the prior art, the existing blocking method is mainly to use aortic clamp to block. If the aortic clamp is used for a long time to clamp the aorta for a long time to block the blood flow, it will damage the aortic bloo

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a hemostatic stent for cardiac macrovascular surgery. The hemostatic stent comprises a sleeve; a pipe head and a pipe tail are arranged at the two ends of the sleeve respectively, the end, away from the sleeve, of the pipe head is in smooth transition and closed, and the pipe tail is in threaded connection with the sleeve; an annular elastic bag is arranged on the periphery of the sleeve, and the elastic bag communicates with an air inlet pipe arranged in the sleeve in the axial direction of the sleeve; the end, away from the elastic bag, of the air inlet pipe communicates with a detachable air tank, and compressed air is contained in the air tank; and the middle of the air inlet pipe communicates with a sliding hole formed in the diameter direction of the sleeve, a sliding column is slidably connected into the sliding hole, a first valve hole is formed in the sliding column, and a circularbead is arranged at an end a, extending out of the sleeve, of the sliding column. By pressing the end a of the sliding column, the built-in air tank can be opened to inflate the elastic bag, hemostasis is achieved after the elastic bag is expanded, connection of the hemostasis stent to excessive pipelines is reduced, and the hemostasis efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, 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 vertebrates. Its main function is to provide pressure for blood flow and to move blood to all parts of the body. The role of the heart is to promote blood flow, provide sufficient blood flow to organs and tissues to supply oxygen and various nutrients, and take away metabolic end products (such as carbon dioxide, inorganic salts, urea and uric acid, etc.), so that cells can maintain Normal metabolism and function. In heart and great vessel surgery, it is often necessary to block a certain section of blood vessel, so that the adjacent blood vessels at the blocked part can be opened for surgical operation. The existing blocking method mainly uses aortic clamp to block. However, heart and great vessel surgery often requires a long opera...
