Description

Hepatic portal vein blocking belt

Technical Field

The utility model relates to the technical field of medical equipment, particularly, relate to a hepatic portal vein blocks area.

Background

The blood supply of the liver is very large, the blood volume of the liver is 14 percent of the total amount of the human body, and the blood flow of the liver of an adult is 1500-2000 ml per minute. The blood vessels of the liver are divided into hepatic and hepatic vessels. Entering hepatic vessels include the intrinsic hepatic artery and portal vein, which are dual vascular supplies. Hepatic vessels are the hepatic venous line. The hepatic artery is a nutrition blood vessel of the liver, 1/4 of the hepatic blood supply is from the hepatic artery to the liver, and then the hepatic blood supply is divided into various branches to the lobular artery, the arterial blood directly from the heart is input into the liver, and the oxygen is mainly supplied. The portal vein is a functional blood vessel of the liver; the 3/4 of the blood supply to the liver comes from the portal vein, which is divided into branches to the lobular intervenosus after entering the liver, and the blood containing nutrients from the digestive tract is sent to the liver for processing.

Because the liver is rich in blood supply, in liver surgery, in order to reduce the condition of liver hemorrhage during the surgery, it is usually necessary to block the blood flow into the liver to reduce the bleeding or oozing of the surgical area. Liver surgery is a major risk, and once the liver resection is started, the second must be considered.

In the prior art, the commonly used method for blocking the hepatic portal blood flow is to block the vein by adopting a blocking belt, but the blocking is often insufficient for one time in the blocking process, and the blocking can be performed for many times, and when the blocking is performed for the next time, a doctor can roughly judge the blocking position for the last time according to good or bad blocking effect, so that the doctor leans against the upper side or the lower side on the basis of the first blocking position, and the doctor does not judge a reference object under general conditions, so that the judgment is not accurate; in addition, when a doctor cuts off the blocking belt, the blocking belt is lost, and the like, in the process, a plurality of blocking belt bodies can be cut off due to improper operation, so that part of the blocking belt is left in the body of a patient, a large amount of time is required to be searched in an operation, the operation time can be delayed, or the blocking belt body is broken and lost due to quality problems, and the like, so that the blocking belt cannot be completely taken out, and the patient is injured.

In view of the deficiencies of the prior art, it would be desirable to provide a hepatic portal vein occlusion band that addresses the problems set forth in the background above.
