Problems solved by technology

[0004] For a long time, intestinal protective ostomy has been widely used because of its definite curative effect; however, for patients who receive this kind of protective ostomy, they generally need to undergo a second operation 1 to 3 months after the operation. Putting the temporary stoma back into the abdominal cavity (re-anastomizing or resecting the part of the intestine previously used for the stoma to restore the continuity of the intestine), the resulting physical pain and economic costs are

Example Embodiment

[0027] Example 1

[0028] Such as Figure 2 ~ Figure 3 As shown, the functional intestinal ostomy sleeve is composed of a drainage tube 21 and an inflation tube 22; the drainage tube 21 and the inflation tube 22 constitute a partly co-piped dual-lumen structure 23, wherein the inflation tube 22 is inflated by the main The tube 221, the inflation tube branch a222, and the inflation tube branch b223 are composed of; an inner airbag a24 is provided on the outer wall of the end of the double-chamber structure 23, an inner airbag b25 is provided on the outer wall of the end of the inflation tube b223, and the main inflation tube An outer airbag 26 is provided at the outer port of 221;

[0029] The inflation tube 22 is composed of a main inflation tube 221, an inflation tube branch a222, and an inflation tube branch b223. ​​The main inflation tube 221 is Y-shaped at its end separated into a proximal inflation tube branch a222 and a distal inflation tube branch b223. ;

Example Embodiment

[0039] Example 2

[0040] Such as Figure 2 ~ Figure 3 As shown, when considering the reintroduction of the stoma, the functional intestinal stoma sleeve may not be removed after the inner balloon a24, the inner balloon b25, and the outer balloon 26 are collapsed; because the double-lumen sleeve structure 23 is in contact with the patient There is a gap between the intestinal wall. After the inner airbag a24, the inner airbag b25 and the outer airbag 26 collapse, the patient's intestinal tract recanalizes. At this time, the intestinal fluid can pass from the proximal intestine to the distal intestine, which can further test the anastomosis. Healing situation: Observe the patient for 1 to 2 days if there are still distal intestinal healing problems (such as anastomotic leakage, stenosis, tumor recurrence compression, etc.), the air sacs can be filled again to block the intestinal juice for further treatment.

[0041] The results of the above examples show that one end (intralumina...

Abstract

The invention belongs to the field of medical apparatus and instruments, and relates to a functional enterostomy cannula. The functional enterostomy cannula is composed of a drainage tube and an inflation tube, wherein the drainage tube and the inflation tube form a double-cavity structure with the partially shared tube; the inflation tube is composed of a main inflation tube body, an inflation tube branch tube body a and an inflation tube branch tube body b; an inner air bag a is arranged on the outer wall of the end part of the double-cavity structure, an inner air bag b is arranged on the outer wall of the end part of the inflation tube branch tube body b, and an outer air bag is arranged on the outer end opening of the main inflation tube body. A use result shows that the functional enterostomy cannula is simple in manufacturing technology, strong in practicability, and low in daily maintenance cost, the second-time operation needed by the conventional stomy resetting is effectively avoided, thus the pain of the patients is alleviated, the medical cost is reduced, meanwhile, the skin irritation beside the stoma is reduced, the living quality of the patients is improved, and the functional enterostomy cannula is suitable for the intestine protective stomy caused by various causes of disease.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a novel postoperative auxiliary device for intestinal surgery, in particular to a functional stoma device for intestinal protective stoma, in particular to a functional intestinal stoma Sleeve: The sleeve is a special structure sleeve, which can effectively avoid the need for secondary surgery when the stoma is retracted after use, and at the same time greatly reduce skin irritation around the stoma. Background technique [0002] In recent years, with the improvement of living standards and changes in lifestyle, the incidence of colorectal cancer in my country has shown an obvious upward trend. According to the 2014 National Cancer Survey released by WHO, more than 250,000 colorectal cancer patients are newly discovered every year in my country, and its incidence rate ranks fifth among all cancers in my country. Thanks to the update of equipment and the improvement of operation leve...
