Improved supporting drainage device used after anastomosis and method thereof

Abstract

The invention relates to an improved supporting drainage device used after anastomosis, which comprises a guide tube and an outer sleeve; the guide tube is located in the outer sleeve and can move relative to the outer sleeve; a supporting body and a bracket body are arranged at the first end of the guide tube and extend out of the first end of the outer sleeve; the bracket body is a supporting bracket; openings are formed in the upper end and the lower end of the supporting bracket, so that digestive juice can freely circulate in the supporting bracket; the supporting body comprises a lifting structure arranged at the lower end of the supporting bracket; the lower end of the lifting structure extends into the guide tube and communicates with a tube cavity of the guide tube; by arranging the lifting structure, the lifting and supporting effects are achieved; and it is guaranteed that the supporting bracket does not fall off when being placed. By innovatively supporting the stretching direction and position of the drainage device, the problem of discomfort caused by the fact that a traditional postoperative patient needs to insert a stomach tube from the nasal cavity is solved, and the incidence rate of inhalation pneumonia is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an improved support and drainage device used after anastomosis and a method thereof. Background technique [0002] Esophagojejunostomy is a common surgical method for digestive tract reconstruction in the treatment of gastric cancer and lower esophageal cancer. After esophagojejunostomy, patients usually need to insert a gastric tube. The gastric tube is inserted through the nasal cavity and reaches the remnant stomach or jejunum through the pharynx. It is mostly used to suck gastric juice and other digestive juices to reduce pressure. However, it is very uncomfortable for patients to wear the gastric tube, especially for some patients who are intolerant, the pharynx is particularly uncomfortable when wearing the gastric tube. Some patients will pull out the gastric tube in their sleep or when they are unconscious, or even Some patients are willing to take ot...

Problems solved by technology

[0005] An improved support and drainage device used after anastomosis, which includes a guide tube and an outer tube; the guide tube is located inside the outer tube, and the guide tube can move relative to the outer tube; the first end of the guide tube is provided with a support body and a support body, the support body and the support body protrude from the first end of the outer casing; the support body is set as a support support, and the upper and lower ends of the support support are provided with openings to ensure the free circulation of digestive fluid inside the support support; The supporting body includes a lifting structure arranged at the lower end of the supporting bracket, and the lower end of the lifting structure extends into the inside of the guide tube and communicates with the lumen of the guiding tube; the setting of the lifting structure plays the role of lifting and supporting, ensuring that the supporting bracket It does not fall off when it is placed; in this way, the outer sleeve extends from the abdominal wall to the designated position on the intestinal wall, and the guide tube is pushed forward or the outer sleeve is retracted, so that the support body and the bracket body protrude from the first end of the outer sleeve, and the support body plays a role. Lifting and supporting to avoid narrow anastomosis, the stent body plays a role of drainage and decompression to avoid overflow of digestive juice; this device overcomes the traditional postoperative patient's need to insert from the nasal cavity by innovatively extending the direction and position of the support and drainage device The discomfort caused by the gastric tube can also effectively reduce the incidence of aspiration pneumonia
