Jejunostomy tube capable of realizing self fixing of small intestine and abdominal wall

Abstract

The invention relates to a jejunostomy tube capable of realizing self fixing of small intestine and abdominal wall. The jejunostomy tube comprises a main tube penetrating through the abdominal wall tobe inserted into the small intestine, wherein a fixer which can be opened in the small intestine and a locking machine which cooperates with the fixer to fix the main tube outside the abdominal walland epidermis are arranged on the main tube, and the fixer can be at least two blade devices, or L-shaped components or disk-shaped components on the periphery of the main tube. According to the jejunostomy tube, the fixer which can be opened in the small intestine and the locking machine outside the abdominal wall are used, the jejunostomy tube is fixed in an inner and outer two-end fixing manner, and the problem that the jejunostomy tube is prolapsed is completely solved. Compared with a conventional fixing manner through suturing between the jejunostomy tube and the jejunostomy tube and theabdominal wall, the fixing manner is more stable, and the operation process is simpler. The fixed jejunostomy tube cannot be prolapsed, a short tube can be reserved in the small intestine, and the small intestine can normally convey and absorb nutrients required by human bodies as far as possible.

Description

technical field [0001] The invention relates to a jejunostomy tube capable of self-fixing the small intestine and the abdominal wall, which is a medical device and a pipeline device for connecting hollow viscera and the abdominal wall. Background technique [0002] For some hollow organs, such as the small intestine and stomach, it is usually necessary to establish a temporary or permanent fistula after surgery to input nutrients and provide enteral nutrition for patients who are temporarily or permanently unable to eat orally. The traditional method is to insert a catheter into the hollow organ through the stoma on the abdominal wall, and suture the serosal surface of the organ and the catheter, the serosal surface of the organ and the peritoneum, and the catheter and the outer skin of the abdominal wall to fix the catheter. The shortcomings of the traditional method are very obvious: 1. The suture between the catheter and the skin outside the abdominal wall is very fragile...

AI Technical Summary

Problems solved by technology

The shortcomings of the traditional method are very obvious: 1. The suture between the catheter and the skin outside the abdominal wall is very fragile. Repeated friction between the catheter and the skin is very easy to open the thread, and it is often necessary to suture again, causing great pain to the patient; Out of the catheter, the suture between the serosal surface of the viscera and the catheter is not reliable. Once the skin fixation line outside the abdominal wall is broken, the catheter can easily slip out of the intestine, and it is difficult to insert the catheter through the original sinus, and reoperation may be required; 3. To prevent the prolapse of the catheter, a longer catheter is often reserved in the hollow organ. The length of the catheter is proportional to the nutrient solution remaining in the catheter. The longer the catheter, the easier it is to block, and sometimes it cannot be re-passed; Improper operation of the suture between the serosal surface of the organ and the catheter may cause narrowing of the intestinal lumen at the suture site, and improper operation of the suture between the serosal surface of the organ and the peritoneum may cause the intestinal tract to form an angle, all of which may result in complete or incomplete postoperative Intestinal obstruction requires another laparotomy, and the suture operation itself prolongs the operation time, which is particularly unfavorable for patients, especially elderly and frail patients
