Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a device for implanting an anti-esophageal reflux filler via an endoscopic channel. 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 to narrow the opening of the cardia, thereby preventing esophageal reflux. However, this method is difficult to control the size of the scar tissue, resulting in a great deal of uncertainty in the size of the cardia opening, which may affect the effectiveness of preventing esophageal reflux.

[0003] To solve the above problems, an anti-esophageal reflux filler has been invented. The filler has an inflatable filling ring. The expansion of the filling ring can change the size of the opening of the cardia, thereby achieving the purpose of preventing esophageal reflux.

[0004] However, there is currently no device that can implant the aforementioned anti-esophageal reflux filler through an endoscopic channel. Utility Model Content

[0005] The main objective of this application is to provide a device for implanting an anti-esophageal reflux filler via an endoscopic channel, which aims to solve the aforementioned technical problems.

[0006] The technical solution adopted in this application is as follows:

[0007] A device for implanting an anti-esophageal reflux implant via an endoscopic channel, comprising:

[0008] A compressible inflatable bladder, wherein a connecting air tube is provided on the compressible inflatable bladder;

[0009] A three-way valve is located at the end of the connecting air tube furthest from the compressible inflatable bladder.

[0010] A sealant injector, which is connected to the connecting air tube and is located near the side of the squeeze-type inflatable bladder;

[0011] An implantation tube, which is connected to the three-way valve;

[0012] An airbag connecting tube, which is connected to the three-way valve;

[0013] The connector is integrally formed with the implantation tube. A countersunk hole for connecting to the implantation tube is provided on the end face of the connector away from the implantation tube. An annular airbag is provided on the side wall of the countersunk hole, and the airbag connecting tube is connected to the annular airbag.

[0014] Optionally, an external connector is provided at one end of the connecting air tube near the compressible inflatable bladder. An adhesive strip is integrally formed on the outer wall of the external connector, and a plug for sealing the external connector is detachably provided on the adhesive strip.

[0015] Optionally, the sealant injector is provided with an injection tube, and the injection tube is provided with a connecting cap that mates with the external connector.

[0016] Optionally, a handle is provided on the connecting air tube.

[0017] Optionally, the airbag connecting tubes are arranged side by side on the outer wall of the implantation tube.

[0018] Compared with the prior art, the beneficial effects of this application are:

[0019] This application provides an instrument for implanting an anti-esophageal reflux filler via an endoscopic channel. The filler is fixed by a connector, and the filler is delivered to the surgical position through the endoscopic channel using an implantation tube. The filler can be inflated by a compression balloon, and after inflation, the filler can be sealed with sealant using a sealant injector, so that the filler always remains inflated. This solves the problem of not being able to implant an anti-esophageal reflux filler via an endoscopic channel. Attached Figure Description

[0033] See attached document Figure 1 This application provides a device for implanting an anti-esophageal reflux filler via an endoscopic channel, such as... Figure 5 and Figure 6 As shown, the device includes a squeeze-type inflatable bladder 6, a connecting air tube 7, a sealant injector 8, a three-way valve 9, an implantation tube 10, a bladder connecting tube 11, and a connector 12. The squeeze-type inflatable bladder 6 has a one-way air inlet valve at its tail, allowing outside air to enter the bladder 6 in one direction. The connecting air tube 7 is a rigid plastic tube integrally formed with the squeeze-type inflatable bladder 6. A handle 13 is fixedly mounted on the connecting air tube 7 for easy hand operation. An external connector 14 is integrally formed on one end of the connecting air tube 7 near the squeeze-type inflatable bladder 6. An adhesive strip is integrally formed on the external connector 14, and a plug is provided on the adhesive strip to seal the external connector 14. The plug can be removed from the external connector 14 for easy connection to the sealant injector 8. The sealant injector 8 has an injection tube, and the end of the injection tube has a connecting cap that mates with the external connector 14.

[0034] In the above description, the three-way valve 9 is connected to the end of the connecting tube 7 furthest 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 implantation tube 10 is a transparent tube, and 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 allows adjustment of 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.

[0035] 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 implantation tube 16 is connected to the countersunk hole 16. The countersunk hole 16 is provided with a lateral annular groove. The annular airbag 15 is fixedly bonded to the lateral annular groove with strong adhesive. The airbag connecting tube 11 passes through the inside of the connector 12 and is fixedly connected to the inside of the annular airbag 15.

[0036] In this embodiment, the connector 12 is used to connect the anti-esophageal reflux filler. Specifically, the anti-esophageal reflux filler includes a filling ring formed by multiple balloon tubes 1. The balloon tubes 1 are made of flexible medical silicone material and have a hollow internal structure, allowing them to expand when inflated. Adjacent balloon tubes 1 are integrally formed with a balloon tube connector 2 through heat fusion, and the balloon tube 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 tubes 1 is composed of four balloon tube connectors 2.

[0037] like Figure 2 and Figure 3As 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 4 As 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.

[0038] 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. These arrow markings are coated with fluorescent agent to facilitate 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 to the implantation instrument, facilitating the implantation of the filling ring into the surgical position. 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.

[0039] Based on the above, the present application provides an endoscopic device for implanting an anti-esophageal reflux filler, the method of which is as follows:

[0040] 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;

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.
