Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to an abdominal endoscopic air bag. Background Art
[0002] The laparoscopic balloon is a medical device used in laparoscopic surgery. Its main functions include expanding the abdominal cavity to improve the surgical field of view and operating space, reducing bleeding during surgery by stopping bleeding through compression, and better separating and exposing tissues and organs in the surgical area by expanding the balloon. The device is usually made of flexible material and connected to an external gas source through a catheter. The doctor can adjust the degree of inflation as needed. The use of the laparoscopic balloon can improve the safety and efficiency of the surgery and reduce the occurrence of intraoperative complications.
[0003] After searching, a laparoscopic dilatation balloon with announcement number CN215135665U includes an inflatable balloon and an air bag, the inflatable balloon and the air bag are movably connected, the outlet end of the inflatable balloon is connected to a hose, the hose is provided with a one-way mechanism and a deflation tube, the deflation tube is located between the one-way mechanism and the outlet end of the hose, the outlet end of the hose is connected to a first connecting tube, the air inlet end of the air bag is provided with a second connecting tube, the first connecting tube and the second connecting tube are movably plugged in. The laparoscopic dilatation balloon replaces the syringe with the inflatable balloon, allowing the operator to inflate with one hand and record the total amount of air intake. The one-way mechanism can change the direction of gas flow to prevent the air in the balloon from flowing out, thereby establishing an artificial cavity through the balloon. The deflation tube can be used to release the balloon gas by opening the sealing rubber plug after inflation is completed, without loosening the connection between the balloon and the hose, which is simple and convenient.
[0004] Based on the above patent, an inflatable balloon replaces a 50ml syringe, allowing the operator to inflate with one hand and record the total amount of air intake. The one-way mechanism can change the direction of gas flow. When the inflatable balloon is squeezed, air enters the balloon, and when the inflated balloon is released, the air in the balloon does not flow out, thereby creating an artificial cavity through the balloon. Through the provided deflation tube, the balloon gas can be released by opening the sealing rubber plug after inflation is completed, without loosening the connection between the balloon and the hose, which is simple and convenient. However, in this patent, when the balloon is installed and assembled, the combined structure between the balloon and the connecting tube does not add a reinforcement structure, resulting in the probability of the balloon falling off during use. The falling off of the balloon limits the surgical operation, increases the operation time and difficulty, and thus increases the risk of intraoperative complications. Utility Model Content

[0029] 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.
[0030] Reference Figure 1 and Figure 2 The utility model provides an embodiment: an abdominal endoscopy airbag, comprising a connecting tube 1 as a main body support, one end of the connecting tube 1 is fixedly connected to an inflatable balloon 2, the other end of the connecting tube 1 is fixedly connected to a resistance tube 3, the left end of the resistance tube 3 is connected to a rubber plug 8 through a deflation group for discharging the gas in the connecting tube 1, the bottom end of the rubber plug 8 is detachably connected to a deflation tube 7, the bottom end of the deflation tube 7 is fixedly connected to a fixed tube 4 and passes through, the right end of the assembly tube 5 is fixedly connected to the left end of the fixed tube 4, and the left end of the resistance tube 3 is fixedly connected to the right end of the fixed tube 4.
[0031] Specifically, when the inflatable balloon 2 is repeatedly pressed, the connecting tube 1 infuses air pressure through the resistance tube 3 along the fixed tube 4 and into the expansion balloon 6 through the assembly tube 5, causing the expansion balloon 6 to expand, allowing it to separate and expose tissues and organs in the surgical area.
[0032] Reference Figure 3 and Figure 4 , as an assembly tube 5 acting as an installation combination, the left end of the outer wall of the assembly tube 5 is slidably connected with an adjusting ring 10, and the four sides of the inner wall of the adjusting ring 10 are connected to the second connecting plate 13 through a disassembly group, the outer wall of the left end of the adjusting ring 10 is fixedly connected with a strong spring 9, and the other end of the strong spring 9 is fixedly connected to the left end of the inner wall of the assembly tube 5, and the inner wall of the assembly tube 5 is connected with a sealing rubber gasket 15 through a sealing group to maintain the airtightness when the connection between the assembly tube 5 and the inflation airbag 6 is made. The first connecting plate 11 is rotatably connected on all four sides of the outer wall of the right end of the adjusting ring 10, and the right end of the first connecting plate 11 is rotatably connected with the extrusion plate 12, and the left end of the second connecting plate 13 is rotatably connected to the right end of the extrusion plate 12, and the right end of the second connecting plate 13 is rotatably connected to the four sides of the outer wall of the assembly tube 5, and the right end of the inflation airbag 6 is fixedly connected to the slide tube 14, and the right end of the slide tube 14 is tightly attached to the outer wall of the left end of the sealing rubber gasket 15.
[0033] Specifically: when it is necessary to assemble the inflation airbag 6 with the assembly tube 5, the chute tube 14 at the inflation airbag 6 is docked at the assembly tube 5, and the adjusting ring 10 is turned to squeeze the strong spring 9 to contract. At the same time, the first connecting plate 11 drives the extrusion plate 12 to cooperate with the second connecting plate 13, so that the extrusion plate 12, the first connecting plate 11 and the second connecting plate 13 are straightened. After the chute tube 14 is docked in the assembly tube 5, the elastic force of the strong spring 9 allows the adjusting ring 10 to make the first connecting plate 11 cooperate with the second connecting plate 13 to allow the extrusion plate 12 to dock at the chute tube 14, and the chute tube 14 is tightly fitted with the sealing rubber pad 15, thereby facilitating the assembly of the inflation airbag 6 with the assembly tube 5.
[0034] Reference Figure 5 and Figure 6 , the resistance tube 3 acts as a check airflow, and the right end of the inner wall of the resistance tube 3 is fixedly connected to a first fixing ring 16. The inner wall of the first fixing ring 16 is connected to a closing plate 19 through a check group to prevent the airflow in the resistance tube 3 from flowing back. The front and rear ends of the inner wall of the first fixing ring 16 are fixedly connected to a connecting block 17, and the left end of the connecting block 17 is fixedly connected to a strong tension spring 18. The other end of the strong tension spring 18 is respectively fixedly connected to the left end of the closing plate 19. The opposite end of the closing plate 19 is rotatably connected to a second fixing ring 20. The outer wall of the second fixing ring 20 is fixedly connected to the inner wall of the resistance tube 3, and the outer diameter of the second fixing ring 20 is the same as that of the first fixing ring 16.
[0035] Specifically: when the gas stops being injected, the strong tension spring 18 connected to the connecting block 17 at the first fixing ring 16 pulls the closing plate 19 to close at the second fixing ring 20, so that the closing plate 19 and the second fixing ring 20 produce a one-way sealing effect, thereby preventing the gas in the inflated airbag 6 from flowing back.
[0036] Working principle: When the inflatable balloon 2 is repeatedly pressed, the connecting tube 1 will infuse the air pressure through the resistance tube 3 along the fixed tube 4 and through the assembly tube 5 into the expansion balloon 6, causing the expansion balloon 6 to expand, allowing it to separate and expose the tissues and organs in the surgical area. When it is necessary to assemble the expansion balloon 6 with the assembly tube 5, the chute tube 14 of the expansion balloon 6 is docked with the assembly tube 5, and the adjusting ring 10 is turned to squeeze the strong spring 9 to contract. At the same time, the first connecting plate 11 drives the squeezing plate 12. Under the cooperation of the second connecting plate 13, the squeezing plate 12, the first connecting plate 11 and the second connecting plate 13 are straightened, and the sliding plate 14 is connected to the assembly tube 5. After the groove tube 14 is docked in the assembly tube 5, the elastic force of the strong spring 9 allows the adjusting ring 10 to make the first connecting plate 11 cooperate with the second connecting plate 13 to allow the extrusion plate 12 to dock with the chute tube 14, and allows the chute tube 14 to fit tightly with the sealing rubber pad 15, thereby facilitating the assembly of the inflation airbag 6 and the assembly tube 5. When the gas stops being infused, the strong tension spring 18 connected to the connecting block 17 at the first fixing ring 16 pulls the closing plate 19 to close at the second fixing ring 20, so that the closing plate 19 and the second fixing ring 20 produce a one-way sealing effect, thereby preventing the gas in the inflation airbag 6 from flowing back.
[0037] 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.
