TECHNICAL FIELD

[0001] The present application relates to the technical field of medical tools, in particular to a single-lumen enterostomy assembly for children and a method. BACKGROUND

[0002] Enterostomy is a common surgical procedure, mainly used for the treatment of various congenital intestinal malformations, necrotizing enterocolitis and other conditions requiring intestinal externalization. Enterostomy creates an opening in the abdominal wall 4 to bring a portion of the intestine outside the body, so that the excrement can be discharged through this opening. Although enterostomy is essential for the treatment of many diseases, it needs to solve many problems when applied to premature infants. For example, in the operation of necrotizing enterocolitis, most of the children are premature infants with a body weight of 500-2000g, the children are severely infected and the condition is critical, and the intestinal wall of premature infants is thin and fragile, which is easy to be sutured, resulting in intestinal fistula, high surgical difficulty, and the need for experienced neonatal surgeons to perform the operation, which takes a long time. These problems not only lead to the fact that some children cannot receive professional treatment, but also increase the risk of surgical damage and may lead to a decrease in the quality of life, causing additional psychological and social burdens to the children and their families. However, the existing enterostomy device, such as the invention patent with the publication number EP3040060A1: "A complete diversion enterostomy surgical kit", although it can reduce the difficulty of the operation, it still needs to be sutured manually, which increases the risk of damage to the intestinal tract of children and leads to a longer operation time. SUMMARY

[0003] The purpose of the present application is to solve the problem of the need for manual suturing in the existing single-lumen enterostomy operation for children, which easily damages the intestinal tract of children, and to provide a single-lumen enterostomy assembly for children that reduces suturing and reduces operation time.

The annular air bag 3 is linked with a syringe through a one-way valve interface, air is pushed in, and the air is injected into the annular air bag 3 through a connecting tube, the syringe is disconnected from the one-way valve interface, the one-way valve rebounds to avoid air leakage, and the shape and pressure of the air bag are maintained. The one-way valve interface and the connecting tube can refer to the design of a tracheal cannula with a bag. The length of the annular air bag 3 along the channel tube 12 can be set as needed when it is filled with air, for example, it can be as long as the channel tube 12 to fill the entire channel tube 12, or as shown, the length of the annular air bag 3 is increased to the inner surface of the abdominal wall 4, so that when it is filled with air, it can be tightly supported in the channel tube 12 and the channel of the abdominal wall, thereby improving the fixation of the annular air bag 3 to the intestinal tract 5. Figure 3

[0050] In addition, the puncture body 21 is provided with a protection section 24 at the end away from the puncture head 22, and the cross-sectional area of the protection section 24 is greater than that of the puncture body 21. The protection section 24 plays a role in preventing the operator's hands from being punctured when puncturing the abdominal wall 4. The puncture body 21 is also provided with a shuttle-shaped protrusion 25, which is arranged on the side of the annular groove 23 away from the puncture head 22. The shuttle-shaped protrusion 25 can expand the channel of the abdominal wall 4 to avoid the intestinal canal 5 being squeezed by the abdominal wall 4 when it is pulled out of the abdominal cavity, thereby reducing the damage.

[0051] In this embodiment, the channel tube 12 is made of transparent material. When the intestinal tract is diseased, the color change of the intestinal tract can be observed through the channel tube 12 to determine whether the intestinal tract is diseased, so that timely measures can be taken. The channel tube 12 can also be made of opaque material, and the presence of disease can be observed directly through the everted part of the intestinal tract.

[0052] ​​The base 1 is fixed on the abdominal wall 4 to prevent the intestinal canal 5 from retracting back, and the intestinal canal 5 is fixed in the channel pipe 12 of the base 1 through the annular air bag 3, so as to increase the force receiving area of the intestinal canal 5 and reduce the damage to the intestinal canal 5 while preventing the intestinal canal 5 from retracting back. After the puncture device 2 is punctured into the abdominal cavity, the intestinal canal 5 is directly sleeved at the annular groove 23 and pulled out, so that the operation is convenient, and the abdominal wall 4 and the intestinal canal 5 are prevented from being damaged when the intestinal canal 5 is pulled out.

[0055] S1: the base 11 of the base 1 is fixed on the abdominal wall 4 of the patient by a suture;

[0056] S2: the puncture device 2 is passed through the channel pipe 12 and is punctured into the abdominal wall 4 to establish an abdominal wall channel;

[0057] S3: the puncture head 22 is inserted into the intestinal canal 5 and is sleeved with the intestinal canal 5 at the annular groove 23, as shown in Figure 4 ;

[0058] S4: after the intestinal canal 5 is led out of the channel pipe 12 through the puncture device 2, the intestinal canal 5 is sleeved on the end of the channel pipe 12;

[0059] S5: the annular air bag 3 is implanted in the intestinal canal 5 and is inflated, so that the intestinal canal 5 is fixed in the channel pipe 12 after the annular air bag 3 is inflated.

[0060] Example two, as shown in Figure 5 and Figure 6 , which is different from example one, the outer side of one end of the channel pipe 12 not connected with the base 1 is provided with a radially protruding annular protrusion 122, and the annular air bag 3 is only tightly supported in the channel pipe 12 when the annular air bag 3 is full of gas. It must be noted that the annular air bag 3 in this example can also be arranged the same as example one. When the intestinal canal 5 is sleeved on the outer side of the annular protrusion 122, the end of the intestinal canal 5 is located at the lower part of the annular protrusion, is naturally contracted, and is firmly sleeved on the annular protrusion 122.

[0061] The method for using the single-lumen enterostomy assembly for children based on Example Two is different from Example One in that, in step S4, after the intestinal tube 5 is led out of the passage tube 12 by the puncture device 2, the intestinal tube 5 is everted and sleeved on the annular protrusion 122 at the end of the passage tube 12.

[0062] Example Three, as shown in Figure 7 and Figure 8 , is different from Example One in that an annular intestinal tube fixing seat 13 is arranged at the end of the passage tube 12 away from the base 11 of the base 1. As shown in Figure 7 , the intestinal tube fixing seat 13 is a circular ring in this factual example. Vertical through holes 131 for passing suture threads are arranged on the intestinal tube fixing seat 13. Different shapes and orientations of the through holes 131 can also be arranged according to requirements. After the intestinal tube 5 is sleeved on the passage tube 12, the intestinal tube 5 is fixed by suture through the intestinal tube fixing seat 13, so that the intestinal tube 5 is more firmly fixed on the base 1. When the annular air bag 3 is filled with air, it is only tightly supported in the passage tube 12. It must be noted that the annular air bag 3 in this example can also be arranged the same as in Example One.

[0063] The method for using the single-lumen enterostomy assembly for children based on Example Three is different from Example One in that, in step S4, after the intestinal tube 5 is led out of the passage tube 12 by the puncture device 2, the intestinal tube 5 is everted and sleeved on the end of the passage tube 12, and the intestinal tube 5 is sutured to the intestinal tube fixing seat 13 by suture through the through holes 131.

[0064] Example Four, as shown in Figures 9-11 , is different from Example Three in that an annular groove 132 with a notch facing away from the abdominal wall 4 is arranged on the intestinal tube fixing seat 13. In this example, through holes 131 for passing suture threads are arranged on the wall surface and the bottom surface of the annular groove 132. The through holes 131 can also be arranged only on the wall surface or the bottom surface. The through holes 131 arranged on the annular groove 132 make suture more convenient. When the annular air bag 3 is filled with air, it is only tightly supported in the passage tube 12. It must be noted that the annular air bag 3 in this example can also be arranged the same as in Example One.

[0065] The method for using the single-lumen enterostomy assembly for children based on Example Four is different from Example One in that, in step S4, after the intestinal tube 5 is led out of the passage tube 12 by the puncture device 2, the intestinal tube 5 is everted and sleeved on the end of the passage tube 12, the end of the intestinal tube 5 is sleeved in the annular groove 132, and the intestinal tube 5 is sutured to the intestinal tube fixing seat 13 by suture through the through holes 131.

[0066] Example Five, as shown in Figure 12 and Figure 13 , is different from Example One in that, in step S1, the intestinal tube 5 is fixed to the abdominal wall 4 by adhesion. The material for adhesion is a skin-friendly material to avoid allergic reactions in children.

[0067] The preferred embodiments of the present application are described in detail above with reference to the accompanying drawings, but the present application is not limited to the specific details of the above-described embodiments.
