[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1 、 Figure 2 and Figure 5, the utility model provides an embodiment: a hepatic portal blocking band with adjustable tightness for surgery, comprising a blocking band 1 for blocking the hepatic portal blood vessels, one end of the blocking band 1 is provided with two adjusting blocks 2, the other end of the blocking band 1 passes through one end of the adjusting block 2, one end of the blocking band 1 is provided with a plurality of positioning holes 5, the other end of the blocking band 1 is provided with two insertion holes 6, the two adjusting blocks 2 are connected, the front side of the upper adjusting block 2 is slidably connected with a positioning rod 11, the middle end of the outer wall of the positioning rod 11 is fixedly connected with a snap ring 13, the top of the positioning rod 11 is fixedly connected with a dial ring 15, the middle end of the inner wall of the positioning hole 5 is provided with a card slot 7, the positioning rod 11 is inserted into the positioning hole 5, and the snap ring 13 is interference fit in the card slot 7;

[0028] Specifically, the liver that needs surgery is tied up at the portal vein through the blocking band 1 to prevent blood flow in the portal vein, thereby reducing bleeding or improving the surgical effect. When the tightness of the blocking band 1 needs to be adjusted, it is only necessary to pull the dial ring 15 to disengage the positioning rod 11 and the buckle ring 13 from the positioning hole 5 and the slot 7 respectively, and then pull the blocking band 1 to adjust the tightness of the blocking band 1. After the adjustment, the positioning rod 11 is inserted into the positioning hole 5 so that the buckle ring 13 is stuck in the slot 7, so that the blocking band 1 is no longer loose, thereby adjusting the tightness of the blocking band 1. The positioning rod 11 and the positioning hole 5 make it possible to quickly adjust the tightness of the blocking band 1, thereby reducing the delay in the patient's surgical work due to adjusting the tightness of the blocking band 1, thereby preventing delays in the surgical process and reducing surgical risks.

[0029] Reference Figure 3 、 Figure 4 and Figure 6 , the upper adjusting block 2 is fixedly connected to two first snap blocks 3 on the front and rear sides, and the bottom adjusting block 2 is fixedly connected to two second snap blocks 4 on the front and rear sides. The left and right sides of the bottom side of the first snap block 3 are fixedly connected to two first plug rods 12, the middle end of the bottom side of the first snap block 3 is fixedly connected to the second plug rod 14, and two first snap grooves 9 are provided on the left and right sides of the top side of the second snap block 4. A second snap groove 10 is provided at the middle end of the top side of the second snap block 4. The first plug rod 12 is inserted into the first snap groove 9, and the second plug rod 14 is inserted into the second snap groove 10. The top side of the bottom adjusting block 2 is fixedly connected to two round rods 8, which pass through the insertion hole 6 and the bottom side of the top adjusting block 2 from bottom to top;

[0030] Specifically, when the blocking belt 1 needs to be replaced, it is only necessary to forcefully move the upper and lower adjustment blocks 2 so that the first insertion rod 12 and the second insertion rod 14 are respectively disengaged from the first snap groove 9 and the second snap groove 10, and the round rod 8 will also be disengaged from the top side adjustment block 2 and the socket 6 on the blocking belt 1. Then the blocking belt 1 can be removed from the adjustment block 2, so that the blocking belt 1 can be replaced or disinfected, which greatly improves the replacement efficiency and cleaning and disinfection efficiency of the blocking belt 1 and improves the convenience of the blocking belt 1.

[0031] Working principle: The liver that needs surgery is tied to the portal vein through the blocking band 1 to prevent blood flow in the portal vein, so as to reduce bleeding or improve the surgical effect. When the tightness of the blocking band 1 needs to be adjusted, it is only necessary to pull the dial ring 15 to make the positioning rod 11 and the buckle ring 13 disengage from the positioning hole 5 and the slot 7 respectively, and then pull the blocking band 1 to adjust the tightness of the blocking band 1. After the adjustment, the positioning rod 11 is inserted into the positioning hole 5 so that the buckle ring 13 is stuck in the slot 7, so that the blocking band 1 is no longer loose, thereby adjusting the tightness of the blocking band 1.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
