Description

Technical Field

[0001] This application relates to the field of medical consumables technology, specifically to an anti-esophageal reflux filler. Background Technology

[0002] Traditionally, esophageal reflux is treated by surgically incising the esophageal wall at the cardia under endoscopy. The esophageal wall heals and forms hyperplastic scar tissue, which narrows the opening of the cardia and thus prevents esophageal reflux.

[0003] However, this method makes it difficult to control the size of scar hyperplasia, resulting in a great deal of uncertainty in the size of the opening of the cardia, which may affect the effectiveness of preventing esophageal reflux. Utility Model Content

[0004] The main objective of this application is to provide an anti-esophageal reflux filler, which aims to solve the above-mentioned technical problems.

[0005] The technical solution adopted in this application is as follows:

[0006] An anti-esophageal reflux filler includes a filling ring formed by multiple segments of balloon tubes, the balloon tubes being connected and formed by balloon tube connectors, each of the balloon tube connectors having a first cylindrical end provided along the axial direction of the filling ring, any of the first cylindrical end having an inflation nozzle, and any of the balloon tube connectors having a second cylindrical end provided along the radial direction of the filling ring.

[0007] Optionally, the inflation nozzle includes an air nozzle housing, the air nozzle housing having a variable diameter inner hole inside, and an air nozzle valve core being provided at the variable diameter end face of the variable diameter inner hole, the air nozzle valve core being fixedly connected to the inner wall of the variable diameter inner hole by a spring.

[0008] Optionally, arrow markings are provided on the bladder tubes on both sides of the bladder tube connector where the inflation nozzle is located.

[0009] Compared with the prior art, the beneficial effects of this application are:

[0010] This application proposes an anti-esophageal reflux filler, which involves circumferentially cutting the intestinal mucosa at the cardia, tearing open the surface mucosa to insert a filling ring inside the mucosa, simultaneously cutting open the mucosa at the inflation nozzle to expose the inflation nozzle, and suturing the filling ring inside the mucosa. By inflating the bladder tube, the bladder tube expands and contracts, thus effectively and accurately controlling the opening size of the cardia and achieving the purpose of effectively preventing reflux.

[0024] See attached document Figure 1 This application provides an anti-esophageal reflux filler, comprising a filling ring formed by multiple segments of balloon tubes 1. The balloon tubes 1 are made of flexible medical-grade silicone material and have a hollow internal structure, allowing for inflation. Adjacent balloon tubes 1 are integrally formed with a balloon tube connector 2 via heat fusion, and the connector 2 communicates with the interior of the balloon tube 1. Specifically, in this embodiment, the filling ring is composed of four equally divided balloon tubes 1, and each of the four balloon tube segments 1 is composed of four balloon tube connectors 2.

[0025] like Figure 2 and Figure 3 As shown, each bladder tube connector 2 has a first cylindrical end 3 arranged along the axial direction of the filling ring. Each first cylindrical end 3 is equipped with an inflation nozzle 5. Air is inflated into the bladder tube 1 through the inflation nozzle 5, causing the filling ring to expand and thus adjusting the opening size of the esophageal sphincter. In this embodiment, as... Figure 4As shown, the inflation nozzle 5 includes an air nozzle housing 501, which is integrally formed on the bladder tube connector 2. The air nozzle housing 501 has a variable diameter inner hole 502 inside. The larger diameter section of the variable diameter inner hole 502 is close to the side of the bladder tube connector 2, and the smaller diameter section is away from the side of the bladder tube connector 2. An air nozzle valve core 503 is provided at the variable diameter end face of the variable diameter inner hole 502. The inner diameter of the air nozzle valve core 503 is larger than the inner diameter of the smaller diameter section but smaller than the inner diameter of the larger diameter section. Thus, in the natural state, the air nozzle valve core 503 seals the smaller diameter section and forms a gap with the larger diameter section. The air nozzle valve core 503 is fixedly connected to the inner wall of the variable diameter inner hole 502 by a spring 504. When inflating, the airflow enters the variable diameter inner hole 502 from the small diameter section. As the airflow enters, the air pressure increases, overcoming the resistance of the spring 504 and pushing the valve core 503 inward. The valve core 503 separates from the small diameter section, and the airflow passes through the gap between the large diameter section and the valve core 503 and enters the bladder tube 1 for inflation.

[0026] Specifically, arrow markings are provided on the balloon tubes 1 on both sides of the balloon tube connector 2 where the inflation nozzle 5 is located. The arrow markings are coated with fluorescent agent to facilitate the visualization of the inflation nozzle 5 under endoscopy. A second cylindrical end 4 is provided on each balloon tube connector 2 along the radial direction of the filling ring, preferably on the symmetrical side of the first cylindrical end 3, to facilitate quick location of the second cylindrical end 4. The second cylindrical end 4 is used to connect with the implantation instrument, facilitating the implantation of the filling ring into the surgical site.

[0027] Among them, such as Figure 5 and Figure 6 As shown, the implantable device includes a compression-type inflatable cuff 6, a connecting tube 7, a sealant injector 8, a three-way valve 9, an implantation tube 10, a cuff connecting tube 11, and a connector 12. The compression-type inflatable cuff 6 has a one-way air inlet valve at its tail, allowing outside air to enter the cuff 6 in one direction. The connecting tube 7 is a rigid plastic tube integrally formed with the compression-type inflatable cuff 6. A handle 13 is fixedly mounted on the connecting tube 7 for easy hand operation. An external connector 14 is integrally formed on one end of the connecting tube 7 near the compression-type inflatable cuff 6. An adhesive strip is integrally formed on the external connector 14, and a plug sealing the external connector 14 is provided on the adhesive strip. The plug can be removed from the external connector 14. The sealant injector has an injection tube, and the end of the injection tube has a connecting cap that mates with the external connector 14.

[0028] In the above description, the three-way valve 9 is connected to the end of the connecting tube 7 away from the compression-type inflatable cuff 6. The remaining two connectors of the three-way valve 9 are connected to the cuff connecting tube 11 and the implantation tube 10, respectively. The cuff connecting tube 11 extends along the outer wall of the implantation tube 10 in the same direction as the implantation tube 10. The three-way valve 9 can be used to adjust the connection between the connecting tube 7 and the cuff connecting tube 11 and the implantation tube 10, respectively. The three-way valve 9 is a conventional three-way ball valve structure, and its structure will not be described in detail here. The connector 12 is integrally formed at the end of the implantation tube 10, and the end of the connector 12 is provided with a countersunk hole 16. The inner diameter of the countersunk hole 16 is larger than the outer diameter of the first cylindrical end 3 and the second cylindrical end 4. The countersunk hole 16 is provided with a lateral annular groove. The annular cuff 15 is fixedly bonded to the lateral annular groove with strong adhesive. The cuff connecting tube 11 passes through the inside of the connector 12 and is fixedly connected to the inside of the annular cuff 15.

[0029] Based on the above, the method of using the anti-esophageal reflux filler provided in this application embodiment is as follows:

[0030] First, the inner wall of the cardia is circumferentially cut under endoscopy, and the intestinal mucosa is torn open, and a hole is made in the torn intestinal mucosa;

[0031] Next, insert the second cylindrical end 4 into the countersunk hole 16 of the connector 12. By rotating the three-way valve 9, connect the connecting air tube 7 to the airbag connecting tube 11. Inflate the annular airbag 15 by pressing the squeezing airbag 6 to make it expand and clamp the second cylindrical end 4. After clamping, rotate the three-way valve 9 to connect the connecting air tube 7 to the implantation tube 10, keeping the annular airbag 15 in an inflated state.

[0032] Then flatten the filling ring (e.g.) Figure 7 (As shown) Insert the device into the endoscope channel and push it inward through the implantation tube 10. Under endoscopy, the filling ring is pushed from the endoscope channel to the circumferential position of the cardia. First, press the squeeze-type inflation balloon 6 to expel a small amount of air into the implantation tube 10. Then, turn the three-way valve 9 to connect the tracheal tube 7 and the balloon connecting tube 11. Release the squeeze-type inflation balloon 6, and the annular balloon 15 will deflate, releasing the second cylindrical end 4. The filling ring will fall from the implantation tube 10, at which point the air in the implantation tube 10 is expelled. Next, adjust the implantation tube 10 so that the first cylindrical end 3 is inserted into the countersunk hole 16 of the connector 12. Press the squeeze-type inflation balloon 6 to inflate the annular balloon 15, causing it to expand and clamp either of the first cylindrical ends 3. After clamping, turn the three-way valve 9 to connect the tracheal tube 7 and the implantation tube 10, keeping the annular balloon 15 in an inflated state.

[0033] Next, the intestinal mucosa is pulled apart using surgical forceps. By adjusting the implantation tube 10, one end of the clamped filling ring is placed between the intestinal mucosa and the submucosal tissue. The first cylindrical ends 3 are clamped in sequence by the connector 12, and the filling ring is placed between the intestinal mucosa and the submucosal tissue. It should be noted that the inflation nozzle 5 should be extended from the opening in the intestinal mucosa to facilitate inflation. After the filling ring is placed, the intestinal mucosa is sutured.

[0034] Then, by adjusting the connector 12, the first cylindrical end 3 with the inflation nozzle 5 is clamped, and the three-way valve 9 is rotated to connect the connecting trachea 7 to the implantation tube 10. The squeezing inflatable bag 6 is pressed to inflate the filling ring, causing it to expand and change the opening size of the cardia, thereby preventing esophageal reflux.

[0035] After inflation is complete, sealant is injected into the inflation nozzle 5 by connecting the sealant syringe 8 to the external connector 14 to seal the inflation nozzle 5 and prevent air leakage. After the sealant injection is completed, the connector 12 is removed from the first cylindrical end 3 and the implantation tube 10 is withdrawn from the endoscope channel.

[0036] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
