Hemostatic stent for heart great vessel surgery

Abstract

The invention relates to the technical field of medical instruments, in particular to a hemostatic stent for heart great vessel surgery, which comprises a sleeve, a pinching ring is fixedly connected to the position, close to the top end, of the annular outer surface of the sleeve, and a sealing block is fixedly connected to the position, close to the bottom end, of the inner surface of the sleeve. The position, close to the middle section, of the sleeve is fixedly connected with a supporting pipe, the outer surface of the supporting pipe is sleeved with a hose, and the upper end and the lower end of the hose are fixedly connected with the sleeve. And the hose is made of a medical silicone rubber material, so that the stress on the inner wall of the blood vessel is more uniform, the inner wall of the blood vessel is not damaged, proper bloodletting treatment can be carried out on the blood vessel with overhigh internal blood pressure, the internal blood pressure of the blood vessel is kept stable, the life safety of a patient is guaranteed, and the surgical risk is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a hemostatic stent for cardiac large vessel surgery. Background technique [0002] The heart is the most important organ in the vertebrate body. Its main function is to provide pressure for blood flow and to run blood to all parts of the body. In the operation of major blood vessels in the heart, it is often necessary to block and stop the bleeding of some blood vessels, so as to prevent the patient from bleeding and ensure the life safety of the patient. Therefore, the hemostasis of the blood vessels is an indispensable and important work in the operation; [0003] The traditional method of hemostasis often uses aortic clamps to block blood vessels, but the operation time of large heart vessels generally lasts for a long time. Using aortic clamps for a long time to clamp the blood vessels can easily cause damage to the clamped part. It affects the later repair, causing ...

Problems solved by technology

[0003] The traditional method of hemostasis often uses aortic clamp to block the blood vessel, but the operation time of the heart and large blood vessels generally lasts for a long time. Using the aortic clamp to clamp the blood vessel for a long time can easily cause damage to the clamped part. It will affect the later repair and bring more troubles to doctors and patients, and the blood pressure may be too high inside the blocked blood vessels. When the blood pressure is too high, it is easy to cause damage to the patient's heart. The internal blood is released in an appropriate amount to maintain the stability of the blood pressure inside the blood vessel. Traditional hemostatic stents do not have this function, and the overall need for improvement
