TECHNICAL FIELD

[0001] The utility model relates to medical tool technical field, concretely relates to a single cavity enterostomy component. BACKGROUND

[0002] Enterostomy is a common surgical operation, mainly used for treating various congenital intestinal deformities, necrotizing enterocolitis and other conditions requiring intestinal externalization. Enterostomy creates an opening on the abdominal wall 4, leading a part of the intestinal tract out of the body, so that excrement can be discharged out of the body through the opening. Although enterostomy is essential for the treatment of many diseases, the existing enterostomy device or method, such as the utility model patent with publication number EP3040060A1: "a complete diversion enterostomy operation kit", needs to be sutured after the opening on the abdominal wall and the intestinal tract during the operation, causing damage to the intestinal tract and the human body, especially when performing enterostomy on children, which is easy to damage the intestinal tract of children and leads to longer operation time. For example, during the operation of necrotizing enterocolitis, most of the children are premature infants with a weight of 500-2000g, the children are severely infected, the disease is critical, and the intestinal wall of the premature infant is thin and fragile, which is easy to be sutured, leading to intestinal fistula, high operation difficulty, and requiring experienced neonatal surgeons to perform the operation, which consumes a lot of time. These problems not only lead to the fact that some children cannot receive professional treatment, but also increase the surgical damage and may lead to a decline in the quality of life, causing additional psychological and social burden to the children and their families.

DETAILED DESCRIPTION

[0037] The specific embodiments described hereinbelow with reference to the drawings are intended to explain and illustrate the present utility model, and are not intended to limit the present utility model.

[0038] Embodiment one, as shown in Figures 1-4 A single-lumen enterostomy assembly includes:

[0039] Base 1, as shown in Figure 1 It includes base 11 for being fixedly connected with abdominal wall 4 and passage pipe 12, one end of passage pipe 12 is connected with base 11, passage 121 in passage pipe 12 penetrates through base 11, base 11 is provided with perforation 111, the number of perforation 111 is set according to the need, and four perforation 111 are in the embodiment, and base 11 is fixed on the abdominal wall 4 of patient by suture line;

[0040] Puncture device 2, as shown in Figure 2 It includes puncture main body 21 and puncture head 22 at the end of puncture main body 21, and annular recess 23 is arranged at the end close to puncture head 22 of puncture main body 21;

[0041] The annular air bag 3 comprises an air bag body and an air valve member for air intake and exhaust of the air bag body. When the air bag body is filled with air, it can be tightly supported in the channel pipe 12, and at the same time, the middle of the annular air bag 3 can still serve as a discharge channel for intestinal contents. The annular air bag 3 is linked with a syringe through a one-way valve interface. The syringe is pushed to inject air into the annular air bag 3 through a connecting pipe. When the syringe is disconnected from the one-way valve interface, the one-way valve rebounds to avoid air leakage, maintain the shape and pressure of the air bag, and the one-way valve interface and the connecting pipe can refer to the design of a tube with a bag. The annular air bag 3 can be arranged along the length of the channel pipe 12 as needed when it is filled with air. For example, it can be as long as the channel pipe 12 to fill the entire channel pipe 12, or it can be increased in length to extend to the inner surface of the abdominal wall 4 as shown in Figure 3 so that when it is filled with air, it can be tightly supported in the channel pipe 12 and the channel of the abdominal wall, thereby improving the fixation of the annular air bag 3 to the intestinal tract 5.

[0042] In addition, the puncture body 21 is provided with a protection section 24 at the end away from the puncture head 22. The cross-sectional area of the protection section 24 is larger than that of the puncture body 21. The protection section 24 plays a role in preventing the operator's hand from being punctured when puncturing the abdominal wall 4. The puncture body 21 is also provided with a shuttle-shaped protrusion 25 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 tract 5 being squeezed by the abdominal wall 4 when it is pulled out of the abdominal cavity, thereby reducing damage.

[0043] In this embodiment, the channel pipe 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 pipe 12 to determine whether the intestinal tract is diseased, thereby taking timely measures. The channel pipe 12 can also be made of opaque material, and the occurrence of disease can be directly observed through the everted part of the intestinal tract.

[0044] The base 1 is fixed to the abdominal wall 4 to prevent the intestinal tract 5 from retracting back. At the same time, the intestinal tract 5 is fixed in the channel pipe 12 of the base 1 by the annular air bag 3. This increases the stress area of the intestinal tract 5 and reduces damage to the intestinal tract 5 while preventing the intestinal tract 5 from retracting back. The entire process can be performed without suturing, greatly reducing the risk of damage to the intestinal tract 5 and improving the efficiency of the operation. After the puncture device 2 is punctured into the abdominal cavity, the opening of the intestinal tract 5 is directly sleeved into the annular groove 23 and pulled out, which is convenient to operate and avoids causing harm to the abdominal wall 4 and the intestinal tract 5 when the intestinal tract 5 is pulled out.
