Embodiment 1

[0025] Such as Figure 1-2 As shown, a device for preventing anastomotic stenosis after esophageal surgery in children includes a tube body 1. It should be noted that the tube body 1 is a nasogastric tube with a length of 100 cm and a circumference of 8Fr or 6Fr gastric tube. 1 The outer fixing sleeve is provided with a cylindrical airbag 2, which is made of polyurethane material. The cylindrical airbag 2 is attached to the outside of the tube body 1 and extends along the axis of the tube body 1. The distance between the lower end of 1 is 10cm, and the distance between the upper end and the lower end of the tube body 1 is 20cm. An elastic sealing film 3 is installed on the inner wall of the tube body 1, and the elastic sealing film 3 and the inner wall of the tube body 1 form a sealed tube channel 4 , the sealing tube 7 communicates with the cylindrical airbag 2 through the tube channel 4 .

[0026] Further, an adapter 5 is installed on the upper end of the pipe body 1, and t...

Embodiment 2

[0035] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that a support rod 13 is fixedly connected to the inner wall of the pipe body 1, the support rod 13 is made of a material that expands with heat and contracts with cold, and the other end of the support rod 13 is elastically sealed. The side wall of the membrane 3 is fixed, and the support rod 13 can shrink when transporting food in the tube body 1, increasing the effective infusion inner diameter in the tube body 1, and stretching when not transporting food, increasing the aperture of the tube channel 4, so as to be convenient to Gas is injected in the cylindrical air bag 2 .

[0036] In this embodiment, when the food is transported in the tube body 1, since the temperature of the outside food is lower than the normal body temperature, the temperature inside the tube body 1 drops, and the support rod 13 shortens under the action of thermal expansion and contraction, so that the elastic ...

Abstract

The invention belongs to the field of medical instruments, and particularly relates to a device for preventing anastomotic stoma stenosis after esophageal surgery of children. The device comprises a tube body, wherein a cylindrical air bag is fixedly arranged outside the tube body in a sleeving mode, is attached to the outside of the tube body and extends in the axis direction of the tube body, an elastic sealing film is mounted on the inner wall of the tube body, a sealed tube barrel channel is formed by the elastic sealing film and the inner wall of the tube body, an adapter is mounted at the upper end of the tube body, a food injection opening connector and a sealing barrel are mounted on the adapter, the food injection opening connector communicates with the upper end of the tube body, a sealing barrel communicates with the cylindrical air bag through the tube barrel channel, and a piston plate is connected into the sealing barrel in a sealing and sliding manner. According to the device, air can be injected into the cylindrical air bag, a narrow esophageal anastomotic stoma can be expanded through tension of the cylindrical air bag, and a pressure monitoring mechanism is arranged, so that the danger that anastomotic mucosa is torn and esophagus perforation is caused due to the fact that pressure in the cylindrical air bag is too large can be avoided, control and operation are convenient, and cost is lower.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a device for preventing anastomotic stenosis after esophageal surgery in children. Background technique [0002] Anastomotic stenosis after esophageal cancer surgery is one of the common complications. There are many reasons for the stenosis, too much anastomotic mixing, small size of the stapler, and scarring of the anastomotic stoma, all of which can lead to anastomotic stenosis. Eating normally seriously affects the quality of life of patients. It is a common complication after esophageal surgery and often requires multiple dilation treatments. [0003] Children often need general anesthesia and X-ray fluoroscopy when undergoing dilation treatment. There are two dilation methods, one is stent therapy, and there is no corresponding children's product for stent therapy at present; the other is endoscopic esophageal balloon dilation This method is not only difficult to operate, bu...
