Description

Technical Field

[0001] The present invention relates to the technical field of medical tools, and in particular to a single-lumen enterostomy component and method for children. Background Art

[0002] Enterostomy in children is a common surgical procedure, mainly used to treat various congenital intestinal malformations, necrotizing enterocolitis, and other conditions that require externalization of the intestine. Enterostomy creates an opening in the abdominal wall 4 to lead part of the intestine out of the body so that excrement can be discharged from the body through this opening. Although enterostomy is essential for the treatment of many diseases, many problems need to be solved when it is applied to premature infants. For example, during the operation of necrotizing enterocolitis, most of the children are premature infants, weighing 500-2000g. The children are seriously infected and in critical condition. At the same time, the intestinal wall of premature infants is thin, brittle, and easy to sew, resulting in intestinal fistulas. The operation is difficult and requires experienced neonatal surgeons to be competent, which takes a long time. These problems will not only cause some children to not receive professional treatment, but also increase surgical injuries, and may also lead to a decline in quality of life, bringing additional psychological and social burdens to children and their families. However, existing enterostomy devices, such as the invention patent with publication number EP3040060A1: "A complete diversion enterostomy surgical kit", although can reduce the difficulty of surgery, still require manual suturing, increase the risk of intestinal damage in children, and cause the operation to take longer. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that manual suturing is required in existing single-lumen enterostomy surgery for children, which easily damages the intestines of children, and to provide a single-lumen enterostomy component for children that reduces suturing and reduces operation time.

[0004] The technical solution provided by the present invention is as follows: a single-chamber enterostomy assembly for children, comprising: A base, comprising a base for being fixedly connected to the abdominal wall and a channel tube, wherein one end of the channel tube is connected to the base, and a channel in the channel tube passes through the base; The puncture device comprises a puncture body and a puncture head located at the end of the puncture body, wherein an annular groove is provided at one end of the puncture body close to the puncture head; The annular airbag can be stretched tightly inside the channel tube when the annular airbag is filled with air.

[0005] When in use, the base is fixed on the abdominal wall of the simulated intestinal fistula, the puncture device passes through the channel tube to establish an abdominal wall channel in the abdominal wall, the puncture head is inserted into the simulated intestinal fistula tube and the simulated intestinal fistula tube is ligated and fixed at the annular groove, and then the puncture device and the simulated intestinal fistula tube are dragged out, and after the puncture device is removed, the intestinal tube is turned inside out and covered on the end of the channel tube, and at the same time, an annular airbag is implanted in the simulated intestinal fistula tube, which bulges after being inflated to fix the intestinal tube in the channel tube.

[0006] The base is fixed on the abdominal wall to prevent the intestinal tube from falling out. At the same time, the intestinal tube is fixed in the channel tube of the base through the annular airbag, which prevents the intestinal tube from retracting and increases the force-bearing area of ​​the intestinal tube, thereby reducing damage to the intestinal tube. After the puncture device is punctured into the abdominal cavity, the stump of the intestinal tube to be fistulated is directly sleeved on the annular groove and pulled out directly, which is easy to operate and avoids damage to the abdominal wall and intestine when the intestine is pulled out. The middle of the annular airbag can still be used as a discharge channel for the intestinal contents. The entire process does not require suturing, which greatly reduces the risk of damage to the intestinal tube and improves the efficiency of the operation.

[0007] Preferably, the puncture body is further provided with a fusiform protrusion, which is arranged on the side of the annular groove facing away from the puncture head. The fusiform protrusion can expand the abdominal wall passage, prevent the intestinal tube from being squeezed by the abdominal wall when it is dragged out of the abdominal cavity, and reduce damage.

[0008] Preferably, the channel tube is made of a transparent material. When the intestinal tract is lesioned, it can be judged by observing the color change of the intestinal appearance in the channel tube, so as to find out in time and take measures.

[0009] Preferably, the base is provided with a perforation for passing sutures, and the base is fixed to the patient's abdominal wall by sutures.

[0010] Preferably, an adhesive layer is provided on the base, and is fixed to the patient's abdominal wall by adhesive means, and the adhesive material is a skin-friendly material to avoid causing allergic reactions in children.

[0011] Preferably, the outer side of one end of the channel tube away from the base is provided with a radially protruding annular protrusion. When the intestinal tube is sleeved on the outer side of the annular protrusion, the end of the intestinal tube is located at the lower part of the protrusion and contracts naturally, so that the end of the intestinal tube is firmly sleeved on the annular protrusion.

[0012] Preferably, an intestinal tube fixing seat is provided at one end of the channel tube away from the base, and the intestinal tube fixing seat is provided with a plurality of through holes for sutures to pass through.

DETAILED DESCRIPTION

[0019] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0020] Embodiment 1, as Figure 1-Figure 4 As shown, a single-lumen enterostomy assembly for children comprises: Base 1, such as Figure 1 As shown, it includes a base 11 and a channel tube 12 for being fixedly connected to the abdominal wall 4, one end of the channel tube 12 is connected to the base 11, a channel 121 in the channel tube 12 passes through the base 11, and the base 11 is provided with a perforation 111. The number of the perforations 111 is set according to needs. In this embodiment, there are four perforations 111. The base 11 is fixed to the abdominal wall 4 of the patient by sutures; Trocar 2, such as Figure 2 As shown, it includes a puncture body 21 and a puncture head 22 located at the end of the puncture body 21, and an annular groove 23 is provided at one end of the puncture body 21 close to the puncture head 22; The annular airbag 3 includes an airbag body and an air valve component for air intake and exhaust of the airbag body. When the airbag body is filled with air, it can be stretched tightly inside the channel tube 12. At the same time, the middle of the annular airbag 3 can still be used as a discharge channel for intestinal contents. The annular airbag 3 is connected to the syringe through a one-way valve interface. The gas is pushed in and injected into the annular airbag 3 through the connecting tube. The syringe and the one-way valve interface are disconnected, and the one-way valve rebounds to prevent air from escaping and maintain the shape and pressure of the airbag. The one-way valve interface and the connecting tube can refer to the design of the endotracheal tube with a balloon. When the annular airbag 3 is filled with air, the length along the channel tube 12 can be set as needed. For example, it can be the same length as the channel tube 12 to fill the entire channel tube 12, or it can be as follows. Figure 3As shown, the annular airbag 3 is lengthened and extended to the inner surface of the abdominal wall 4 , so that when filled with air, it can be stretched tightly in the channel tube 12 and the channel of the abdominal wall, thereby improving the fixing effect of the annular airbag 3 on the intestine 5 .

[0021] In addition, a protective section 24 is provided at one end of the puncture body 21 away from the puncture head 22, and the cross-sectional area of ​​the protective section 24 is larger than the cross-sectional area of ​​the puncture body 21.

The puncture body 21 is also provided with a fusiform protrusion 25, which is arranged on the side of the annular groove 23 facing away from the puncture head 22. The fusiform protrusion 25 can expand the passage of the abdominal wall 4, prevent the intestinal tube 5 from being squeezed by the abdominal wall 4 when it is out of the abdominal cavity, and reduce damage.

[0022] In this embodiment, the channel tube 12 is made of a transparent material. When the intestinal tract is lesioned, it can be judged by observing the color change of the intestinal appearance in the channel tube 12, so as to find out in time and take measures. The channel tube 12 can also be made of an opaque material, and the intestinal part that is turned outward can be directly observed to see whether the disease has occurred.

[0023] The base 1 is fixed on the abdominal wall 4 to prevent the intestinal tube 5 from slipping back. At the same time, the intestinal tube 5 is fixed in the channel tube 12 of the base 1 through the annular airbag 3, which increases the force-bearing area of ​​the intestinal tube 5 while preventing the intestinal tube 5 from retracting, thereby reducing damage to the intestinal tube 5. After the puncture device 2 is pierced into the abdominal cavity, the broken end of the intestine 5 is directly sleeved on the annular groove 23 and directly pulled out, which is easy to operate and avoids damage to the abdominal wall 4 and the intestine 5 when the intestine 5 is pulled out. The whole process does not require suturing, which greatly reduces the risk of damage to the intestinal tube 5 and improves the efficiency of the operation.

[0024] When in use, the base 1 is fixed on the abdominal wall 4 of the simulated intestinal fistula, the puncture device 2 passes through the channel tube 12 to establish an abdominal wall 4 channel in the abdominal wall 4, the puncture head 22 is inserted into the intestinal tube 5 of the simulated fistula and the intestinal tube 5 of the simulated fistula is ligated and fixed at the annular groove 23, and then the puncture device 2 is dragged out together with the intestinal tube 5 of the simulated fistula, and after the puncture device 2 is removed, it is turned outward and covered on the end of the channel tube 12, and at the same time, an annular airbag 3 is implanted in the intestinal tube 5 of the simulated fistula, and the annular airbag 3 bulges after being inflated to fix the intestinal tube 5 in the channel tube 12.
