Embodiment 1

[0028] like Figure 1-4 As shown, the pressure-adjustable porta hepatic blocker includes air bag A1, air bag B2, one-way air valve 3 and pressure gauge 4.

[0029] The airbag A1 is in the shape of a strip, on which there is an inflation port 11 and a pressure gauge interface 12, and movable buckles are installed at both ends, and the movable buckle includes an interface 13 and a plug 14, which can be connected or separated from each other. In the connected state, the airbag A1 is surrounded by a ring, and the inner and outer surfaces of the ring are defined as the contact surface 15 and the outer surface 16 respectively, and the inflation port 11 and the pressure gauge interface 12 are located at the end of the airbag A1 near the interface 13 On the outer side 14 of.

[0030] The airbag B2 is provided with an air outlet 21, and the air outlet 21 of the airbag B2 communicates with the inflation port 11 of the airbag A1 through a hose.

[0031] The one-way air valve 3 is arran...

Embodiment 2

[0036] Compared with Embodiment 1, this embodiment differs only in that the length of the airbag A1 is 9 cm, the width is 0.55 cm, and the thickness is 0.2 cm.

Embodiment 3

[0038] Compared with Embodiment 1, this embodiment differs only in that the length of the airbag A1 is 11 cm, the width is 0.65 cm, and the thickness is 0.4 cm.

[0039] Briefly describe the use of the present invention:

[0040] 1. According to the size of the patient's hepatoduodenal ligament, select the airbag A1 with the appropriate size, clamp the airbag A1, pass the plug 14 through the back of the hepatoduodenal ligament, and wrap it around the hepatoduodenal ligament , inserted into the interface 13, so that the airbag A1 forms a ring;

[0041] 2. Press the airbag B2 and inflate the airbag A1. It can be seen that the airbag A1 is bulging, and the hole in the middle of the airbag A1 gradually shrinks, compressing the hepatoduodenal ligament, thereby blocking the portal vein and hepatic artery in the hepatoduodenal ligament. to achieve a blocking effect.

[0042] During the inflation process, the indication of the pressure gauge 4 gradually increases, and the surgeon ca...

Abstract

The invention provides a pressure-adjustable hepatic portal occlusion device and an occlusion method, and relates to the technical field of surgical instruments. The pressure-adjustable hepatic portalocclusion device comprises an air bag A, an air bag B, a one-way air valve and a pressure gauge, wherein the air bag A is strip-shaped; an inflation inlet and a pressure gauge interface are formed inthe air bag A; movable buckles are mounted at two ends of the air bag A and can be connected or separated; when the movable buckles are in a connected state, the air bag A forms a circular ring; an air outlet is formed in the air bag B and communicated with the inflation inlet of the air bag A; the one-way air valve is arranged between the inflation inlet of the air bag A and the air outlet of the air bag B; and the pressure gauge is connected onto the pressure gauge interface of the air bag A. The hepatic portal occlusion method is applied to the pressure-adjustable hepatic portal occlusiondevice. The inflation amount can be adjusted and controlled on the basis of a display value of the pressure gauge, and the occlusion tightness degree is accurately adjusted and controlled.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a hepatic portal blocker with adjustable pressure and a blocking method. Background technique [0002] Liver surgery is a very important branch of surgery, especially in my country, which is the "hardest hit area" of hepatitis and cirrhosis. my country has more than half of the world's liver cancer patients and a large number of patients with intrahepatic gallstones. Therefore, the development of liver surgery is in the Our country is particularly important and urgent. [0003] As we all know, the liver is a blood-rich organ. About 1000ml of blood passes through the adult liver every minute, which has the characteristics of high flow rate and fast speed. In hepatobiliary surgery, hepatic portal occlusion is required to reduce the amount of bleeding before operating on the liver during surgery. At present, the routine method for blocking the hepatic hilum in liver la...
