Description

TECHNICAL FIELD

[0001] The utility model relates to a blood flow on-off device, especially an automatic adjustment liver duodenal ligament portal vein and hepatic artery blood flow on-off device, belong to surgical medical instrument technical field. BACKGROUND

[0002] Liver is an organ with rich blood supply, and its total blood flow accounts for about 1 / 4 of the cardiac output, with a blood flow of 1500mL per minute. The first hepatic portal is an important channel of the liver, and the blood flow of the portal vein and hepatic artery wrapped around the liver duodenal ligament needs to flow into the liver through the first hepatic portal. For a long time, the control of bleeding in liver surgery has been a difficult problem in the development of liver surgery. Currently, Pringle method and the use of vascular clamp fixation method are commonly used to block the blood flow of the first hepatic portal. Although Pringle method is simple and practical, it can be used for various types of liver resection surgery, but this method can cause obvious liver warm ischemia-reperfusion injury, and it can damage the bile duct, artery and vein wall in the liver duodenal ligament, or cause the death of the wall feeding blood vessels, or cause the rupture of the portal vein; at the same time, the blocking time of the first hepatic portal by this method is limited, and if the blocking time is too long, it is easy to cause severe liver ischemia, so it is necessary to loosen the silicone tube to supply blood to the liver for a short time, and then tighten the silicone tube again to block the first hepatic portal for surgery, and repeated loosening or tightening of the silicone tube is operated in the abdominal cavity, which is more troublesome and risky, and is easy to affect other organs.

[0003] In view of the above problems, the inventor has proposed a utility model named "Adjustable liver duodenal ligament blocking device", with publication number "CN 216455156 U", which has certain innovation in liver portal blood flow blocking, but still has some shortcomings: (1) Although compared with the traditional Pringle method, the blocking device simplifies the operation to a certain extent, but the overall process is still relatively complicated, and a series of operation steps require high operation skills and proficiency of the doctor, which increases the preparation time of the surgery, and if the operation is not proper, it may delay the progress of the surgery; (2) Whether the piercing part is directly connected with the pressure pipe or connected through the connecting pipe, complex operation in the abdominal cavity is needed, and when the piercing part is pierced out of the abdominal wall, if the operation is not careful, it is easy to damage other organs, blood vessels and tissues in the abdominal cavity, increasing the risk of surgery and trauma to the patient; (3) The connection and operation of the pressure supply assembly in the actual surgical environment may be disturbed by various factors, and the connection and operation may be inconvenient, affecting the use efficiency; (4) The elasticity may have elasticity fatigue problem, and the elasticity decreases after repeated expansion and contraction, resulting in unstable blocking effect of the capsule on the hepatic portal, and it is difficult to ensure stable and effective blood flow blocking during the operation.
