Description

Technical Field

[0001] This utility model relates to the technical field of medical blood flow blocking bands, specifically a simple self-locking hepatic hilum blood flow blocking band. Background Technology

[0002] The liver has a rich blood supply, and there is a lot of venous bleeding during liver resection. The blood flow occlusion methods commonly used in open surgery are difficult to perform under laparoscopy, and require a special trocar to clamp the occlusion band. The application and development of laparoscopic liver blood flow occlusion technology is an important foundation for the development of liver resection technology.

[0003] Existing medical blood flow blocking bands use buckle rings for self-locking, which are difficult to unlock during and after hepatic hilum surgery, resulting in excessive blood flow to the liver. Therefore, they cannot quickly and promptly lock in place to block blood flow when there is venous bleeding during liver resection. Utility Model Content

[0004] The purpose of this invention is to provide a simple self-locking hepatic hilum blood flow blocking band to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A simplified self-locking hepatic hilum blood flow occlusion band includes an occlusion band end, an extension occlusion band, a through hole, and a self-locking assembly. The extension occlusion band is fixedly connected to the end of the occlusion band. One end of the extension occlusion band on the self-locking assembly has a through hole. The occlusion band end and the extension occlusion band can be bent and elastically clamped and locked inside the through hole. The band also includes...

[0007] A blocking component is installed on the through hole;

[0008] A self-locking blocking component is disposed on the through hole;

[0009] The through hole is fixedly connected to a self-locking blocking strip, and a blocking strip end is fixedly connected to the end of the self-locking blocking strip. A friction strip is fixedly connected to the inner side of the self-locking blocking strip.

[0010] The simplified self-locking hepatic hilum blood flow blocking band as described above: the blocking self-locking band and the end of the blocking band can be bent and pass through the through hole for elastic clamping and self-locking.

[0011] The simplified self-locking hepatic hilum blood flow blocking band as described above: the blocking component includes an elastic band fixedly connected to the through hole, and an external elastic band is fixedly connected to the outside of the elastic band.

[0012] The simplified self-locking hepatic hilum blood flow blocking band described above: the outer elastic band is fixedly connected to the self-locking blocking band through a blocking extension band, the blocking extension band being made of latex and having a length of 12-15 cm.

[0013] The simplified self-locking hepatic hilum blood flow blocking band as described above: the blocking self-locking component includes a perforated blocking band fixedly connected to one end of the blocking band.

[0014] The simplified self-locking hepatic hilum blood flow blocking band as described above: the perforated blocking band passes through the inside of the perforation hole, and the end of the blocking band can be clamped and self-locked inside the perforation hole.

[0015] The simplified self-locking hepatic hilum blood flow blocking band described above: the shape and structure of the perforated blocking band are the same as the shape and structure of the blocking band end.

[0016] Compared with the prior art, the beneficial effects of this utility model are: after the end of the blocking band and the perforated blocking band pass through the inside of the perforation hole, the thicker blocking self-locking band is elastically squeezed and deformed to pass through the inside of the perforation hole. The outer elastic band and elastic band can elastically wrap around the outside of the blocking self-locking band to lock the blood flow blocking band. The blocking self-locking band at the end of the blocking band wraps around the porta hepatis. The blocking self-locking band bends and locks itself on the liver to block the blood flow and prevent excessive blood flow to the liver. When there is venous bleeding during liver resection, the blocking self-locking band can lock the blood flow in a timely and rapid manner.

[0017] The external elastic band and elastic band through the hole can replace the blood flow blocking band locking ring. The external elastic band and elastic band through the hole can clamp and lock. After the operation of the hepatic hilum, the user can directly pull the blocking extension band in the opposite direction to release the blocking band end and the blocking extension band on the hepatic hilum. This prevents excessive tightness from causing excessive blood flow to the liver due to excessive release time. In case of venous bleeding during liver resection, the blocking band end and the blocking extension band can be pulled in the right direction in time to quickly lock and block the blood flow.

[0027] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0028] Please see Figures 1-6 A simplified self-locking hepatic hilum blood flow occlusion band is proposed, comprising an occlusion band end 1, an occlusion extension band 2, a through hole 3, and a self-locking component.

[0029] A blocking extension band 2 is fixedly connected to the broken extension section of the blocking band end 1. A through hole 3 is provided at one end of the blocking extension band 2 on the self-locking assembly. The blocking band end 1 and the blocking extension band 2 can be bent and pass through the through hole 3 to elastically clamp and lock themselves. The blocking assembly is installed on the through hole 3. The blocking self-locking assembly is set on the through hole 3. A blocking self-locking band 4 is fixedly connected to the outside of the through hole 3. A blocking band end 5 is fixedly connected to the end of the blocking self-locking band 4. A friction crossbar 9 is fixedly connected to the inside of the blocking self-locking band 4.

[0030] In this embodiment, the end 5 of the self-locking band 4 can pass through the through hole 3, so that the self-locking band 4 can wrap around the outside of the hepatic hilum. The self-locking band 4 passes through the small through hole 3 through the end 5 of the band with a smaller diameter. The through hole 3 on the extension band 2 can elastically self-lock around the outside of the self-locking band 4. The self-locking band 4 can prevent the self-locking from being too tight or too loose by its own elasticity. The user can manually pass through the self-locking band 4 and the end 5 of the band. The through hole 3 on the extension band 2 can self-lock elastically wrap around the outside of the self-locking band 4, so as to achieve an elastic self-locking effect.

[0031] Preferably, the self-locking band 4 and the end 5 of the band can be bent through the through hole 3 to elastically clamp and lock.

[0032] The self-locking band 4 and the end of the band 5 can wrap around the outside of the porta hepatis. The self-locking band 4 and the end of the band 5 bend and pass through the through hole 3. The self-locking band 4 and the end of the band 5 can wrap around the outside of the porta hepatis. They are elastically clamped to the outside of the self-locking band 4 through the through hole 3 on the extension band 2, which can block blood flow to the porta hepatis inside the self-locking band 4 and the end of the band 5.

[0033] Please refer to Figure 1 and Figure 3 In this embodiment, the blocking component includes an elastic band 6 fixedly connected to the through hole 3, and an outer elastic band 7 fixedly connected to the outside of the elastic band 6.

[0034] The elastic band 6 is fixedly connected to the through hole 3 on the blocking extension band 2, which can elastically wrap the outside of the through hole 3, so that the outer elastic band 7 is fixedly connected to the elastic band 6. The outer elastic band 7 and the elastic band 6 can improve the elasticity of the through hole 3. When the blocking self-locking band 4 and the end of the blocking band 5 bend and pass through the inside of the through hole 3, the outer elastic band 7 and the elastic band 6 can elastically wrap the outside of the blocking self-locking band 4 and the end of the blocking band 5, which can perform hepatic hilum self-locking blood flow blocking.

[0035] Preferably, the outer elastic band 7 is fixedly connected to the blocking extension band 2 and the blocking self-locking band 4. The blocking extension band 2 is made of latex and has a length of 12-15 cm. The through hole 3 is opened on the blocking extension band 2, so that the blocking extension band 2 is fixedly connected to the through hole 3 by the outer elastic band 7 and the elastic band 6. The through hole 3 is fixedly connected to the blocking self-locking band 4 by the outer elastic band 7 and the elastic band 6. The outer elastic band 7, through the blocking extension band 2 and the blocking self-locking band 4, bends and wraps around the hepatic hilum to lock the blood flow.

[0036] Please refer to Figure 1 and Figure 4 In this embodiment, the self-locking blocking component includes a perforated blocking strip 8 fixedly connected to one end of the blocking strip end 5.

[0037] The end 5 of the blocking band can pass through the through hole 3 through the perforated blocking band 8 at one end. After the end 5 of the blocking band and the perforated blocking band 8 pass through the through hole 3, the thicker self-locking blocking band 4 is elastically squeezed and deformed to pass through the through hole 3. The outer elastic band 7 and the elastic band 6 can elastically wrap around the outside of the self-locking blocking band 4 to achieve self-locking of the blood flow blocking band.

[0038] Preferably, the perforation blocking band 8 passes through the inside of the perforation hole 3, and the end 5 of the blocking band can be clamped and locked inside the perforation hole 3. After the perforation blocking band 8 passes through the inside of the perforation hole 3, the end 5 of the blocking band passes through the inside of the perforation hole 3 through the perforation blocking band 8. The end 5 of the blocking band is squeezed and deformed and locked inside the perforation hole 3. The user can manually block the end 5 of the band, and the self-locking band 4 on the end 5 of the blocking band tightens and locks itself outside the porta hepatis to block blood flow.

[0039] Preferably, the shape and structure of the perforated blocking band 8 are the same as those of the blocking band end 1. When the self-locking length of the blocking self-locking band 4 is too short, the blocking band end 1, which has the same shape and structure as the perforated blocking band 8, can be passed through the through hole 3. The blocking extension band 2 on the blocking band end 1 can be squeezed and deformed to self-lock in the through hole 3. The outer elastic band 7 and elastic band 6 on the through hole 3 can replace the blood flow blocking band lock ring. The outer elastic band 7 and elastic band 6 on the through hole 3 can clamp and self-lock. After the hepatic hilum surgery, the user can directly pull the blocking extension band 2 in the opposite direction to untie the blocking band end 1 and the blocking extension band 2 on the hepatic hilum, preventing excessive blood flow to the liver due to excessive tightness and long untying time. In case of venous bleeding during hepatectomy, the blocking band end 1 and the blocking extension band 2 can be pulled in the right direction in time to quickly self-lock and block blood flow.

[0040] As can be seen from the above, the extension band 2 on the end 1 of the blocking band can be squeezed and deformed to self-lock inside the through hole 3. The outer elastic band 7 and elastic band 6 on the through hole 3 can replace the blood flow blocking band locking ring. The outer elastic band 7 and elastic band 6 on the through hole 3 are used for clamping and self-locking. The outer elastic band 7 is fixedly connected to the elastic band 6. The outer elastic band 7 and elastic band 6 can improve the elasticity of the through hole 3. When the self-locking band 4 and the end 5 of the blocking band bend and pass through the inside of the through hole 3, the outer elastic band 7 and elastic band 6 can elastically wrap around the outside of the self-locking band 4 and the end 5 of the blocking band to perform self-locking blood flow blocking at the porta hepatis.

[0041] The outer elastic band 7 and the elastic band 6 are fixedly connected to the blocking self-locking band 4 through the through hole 3. The outer elastic band 7 is bent and wrapped around the hepatic hilum through the blocking extension band 2 and the blocking self-locking band 4 to lock the blood flow.
