Embodiment 1

[0031] Example 1; see Figure 1-6 , a liver cross-section blood flow blocking device, comprising a fixed ring 1, the top and bottom of the inner wall of the fixed ring 1 are respectively integrally formed with an upper limit sleeve 3 and a lower limit sleeve 2 for passing through the latex tube, and a bottom of the upper limit sleeve 3 The center of the center and the top of the lower limit sleeve 2 are respectively provided with a first through groove 32 and a second through groove 4, the center of the top of the fixed ring 1 is fixedly connected with a closed pipe 5, and the inside of the closed pipe 5 is slidingly connected with a movable pipe along the vertical direction 6. The center of the top of the upper limit sleeve 3 and the center of the top of the fixed ring 1 are respectively provided with a first through hole 31 and a second through hole, and the bottom of the movable pipe 6 passes through the first through hole 31 and the second through hole and extends to the up...

Embodiment 2

[0032] The difference between Embodiment 2 and Embodiment 1 is that a pipe joint 12 is fixedly connected to the top of the closed pipe 5 and close to the front, and a check valve is arranged inside the pipe joint 12, and the device can fill the closed pipe 5 with an air pump. Inject gas to increase its internal pressure, and then achieve the purpose of pushing the movable pipeline 6, instead of the traditional working method of fixing the latex tube by twisting a screwdriver or using surgical forceps.

Embodiment 3

[0033] The difference between embodiment 3 and embodiment 2 is; please refer to Figure 1-3 , the diameter of the slide rod 8 is smaller than the inner diameter of the movable pipe 6, and the top of the slide rod 8 is fixedly connected with a piston 9 that fits the inner wall of the movable pipe 6, so that the internal air pressure of the movable pipe 6 can push the slide rod 8 to slide downward, The bottom of the movable pipe 6 is provided with an outlet for passing through the slide rod 8, and the outlet is fixedly connected with a sealing ring 61 attached to the surface of the slide rod 8, and the diameter of the first through hole 31 and the second through hole is the same as that of the movable pipe 6. Similarly, the center of the left and right sides of the movable pipeline 6 is provided with a limit groove 62 along the vertical direction, and a limit block 16 is integrally formed on the inside of the second through hole and at a position corresponding to the limit groove...

Abstract

The invention relates to the technical field of liver operation tools, in particular to a liver section blood flow blocking device which comprises a fixing ring, and an upper limiting sleeve and a lower limiting sleeve which are used for penetrating through a latex tube are integrally formed at the top and the bottom of the inner wall of the fixing ring respectively. A first through groove and a second through groove are formed in the center of the bottom of the upper limiting sleeve and the center of the top of the lower limiting sleeve correspondingly, a closed pipeline is fixedly connected to the center of the top of the fixing ring, a movable pipeline is slidably connected into the closed pipeline in the vertical direction, and an air inlet is formed in the center of the top of the movable pipeline. A sliding rod is slidably connected into the movable pipeline in the vertical direction, and the bottom of the sliding rod penetrates through the bottom of the movable pipeline and is fixedly connected with an extrusion head. According to the latex tube fixing device, gas can be inflated into the closed pipeline through the inflator pump to increase the pressure in the closed pipeline, then the purpose of pushing the movable pipeline is achieved, and the traditional working mode that a latex tube is fixed by screwing a screwdriver or using operating forceps is replaced.

Description

technical field [0001] The invention relates to the technical field of liver surgery tools, in particular to a liver section blood flow blocking device. Background technique [0002] At present, benign or malignant liver tumors are treated by resection of the liver. In the resection operation, blood flow forging is the key to the success of the operation. [0003] During the operation, a latex tube is usually used to pass through the tear of the hepatogastric ligament, bypass the hepatoduodenal ligament, cross and tighten it on the front side, and then clamp it with a hepatic portal blocking forceps or a latch The buckle is stuck, and the latex tube is squeezed and fixed by turning the screwdriver. Due to the limited position at the surgical site, it is relatively difficult to turn the screwdriver, and it is easy to cause the overall movement of the device when turning the screwdriver, which is likely to cause the latex tube to loosen. When loosening after the operation, th...
