Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically, it relates to a transitional drainage tube before closing an enterostomy fistula. Background Art

[0002] Neonatal enterostomy is a common surgical method for treating necrotizing enterocolitis in premature infants, congenital digestive tract malformations such as congenital anal atresia, intestinal atresia, etc. An enterostomy is an opening formed surgically in the intestinal system, and these openings all lead to the abdominal surface for discharging feces. The types of pediatric enterostomies include single-lumen stomas, double-lumen stomas, T-shaped stomas, etc., and most are temporary stomas, which are usually closed about 3 to 6 months after the operation. Before closing the fistula after enterostomy, the anal defecation situation can be observed by temporarily closing the stoma / connecting the proximal and distal stomas to assist in judging the timing of closing the fistula, and there is currently no suitable closing / connecting method in clinical practice. During the process of closing the fistula operation, during laparotomy exploration, it may be found that the distal intestinal tube is too narrow or adherent, resulting in the inability to directly perform the fistula closure operation. It is necessary to make an anastomosed T-tube connection and create an additional stoma, increasing the risk burden of neonatal surgery.

[0003] In view of the above problems, the present invention provides a transitional drainage tube before closing an enterostomy fistula, which can be used for drainage, and can also be used to temporarily close the stoma / connect the proximal and distal stomas. It can be used as a contrast agent passage before closing the fistula and replace the T-tube anastomosis before closing the fistula, attempt to start feeding at the distal end, promote the dilation of the distal intestinal tube, increase the success rate of the fistula closure operation, reduce complications, and is easy to operate.

[0024] Embodiment: An intestinal fistula closure preoperative transitional drainage tube, as Figure 1 shown in Figure 2 , includes a tube body 1. A fistula bag interface 2 is provided in the middle of the tube body 1, and the fistula bag interface 2 is integrally formed with the tube body 1; a regulating valve one 7 is provided at the fistula bag interface 2 for regulating the flow rate at the fistula bag interface 2. The fistula bag interface 2 is obliquely arranged on the tube body 1, and the included angle between the fistula bag interface 2 and the tube body 1 is 30° - 45°, which is convenient for injecting contrast agent and milk into the distal end 9 of the intestinal stoma in the later stage. Both the tube body 1 and the fistula bag interface 2 are made of medical-grade soft silicone material. Anti-disengagement parts one 3 and anti-disengagement parts two 5 are respectively provided on the outer sides of the two ends of the tube body 1. Grooves 11 are provided above the anti-disengagement parts one 3 and anti-disengagement parts two 5 at both ends of the tube body 1. During use, the tube body 1 of this transitional drainage tube can be tied and fixed to the proximal end 10 and the distal end 9 of the intestinal stoma through thick silk threads to further prevent falling off. A regulating valve two 8 is provided at one end of the tube body 1 where the anti-disengagement part two 5 is provided. The regulating valve one 7 and the regulating valve two 8 are one of a ball valve, a gate valve or a butterfly valve that can control and regulate the flow rate.

[0025] It is further set that: both the anti-disengagement part one 3 and the anti-disengagement part two 5 are inflatable air bags, and both are provided with air filling tubes with self-control valves.

[0026] It is further set that: both the anti-disengagement part one 3 and the anti-disengagement part two 5 are water injection water bags; the anti-disengagement part one 3 is further provided with a water injection tube and an injection port one 4 at the end of the water injection tube, and the anti-disengagement part two 5 is further provided with a water injection tube and an injection port two 6 at the end of the water injection tube.

[0027] During use, one end of the tube body 1 where the anti-disengagement part one 3 is provided is inserted into and connected to the distal end 9 of the intestinal stoma, and one end of the tube body 1 where the anti-disengagement part two 5 is provided is inserted into and connected to the proximal end 10 of the intestinal stoma. Gas or normal saline is respectively injected into the anti-disengagement part one 3 and the anti-disengagement part two 5 to make the anti-disengagement part one 3 and the anti-disengagement part two 5 expand and clamp at the intestinal stoma to prevent the tube body 1 from falling off; the fistula bag interface 2 is connected to an external fistula bag, and the flow rate in the tube body 1 is controlled and regulated through the regulating valve one 7 and the regulating valve two 8.

[0028] Through this transitional drainage tube, drainage from the proximal end 10 of the intestinal stoma to the distal end 9 of the intestinal stoma is achieved. The chyme intestinal juice digestive juice digested by the intestinal juice of the intestinal tube at the proximal end 10 of the intestinal stoma then passes through the transitional drainage tube and enters the intestinal tube at the distal end 9 of the intestinal stoma, observing whether the intestinal tube at the distal end 9 of the intestinal stoma can tolerate it and whether there is stenosis of the distal intestinal tube after fistulation.

[0029] This specific embodiment is only an explanation of the present invention and is not a limitation thereof. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
