Description

Intraoperative intestinal tube interface device and its containing device

technical field

The invention relates to a medical device, in particular to an intraoperative intestinal tube interface device and its accommodating device for gastrointestinal surgery.

Background technique

In clinical practice, intestinal obstruction is a very common and difficult problem, and its etiology is very complex: gastrointestinal tumors, abdominal adhesions caused by various reasons, intestinal vascular disease, foreign bodies in the intestinal cavity, and chronic constipation can all lead to intestinal obstruction. obstruction. In the process of treatment, it is necessary to decide which treatment to take according to the degree and nature of the obstruction. Generally speaking, acute complete intestinal obstruction, or intestinal obstruction accompanied by blood flow disorder, or intestinal obstruction that cannot be relieved after 48-72 hours of conservative medical treatment requires surgical treatment. During the operation, a very important link is the decompression of the dilated bowel, which is beneficial to restore the blood supply of the intestinal wall and reduce the absorption of toxins.

At present, the main methods of intestinal decompression include opening on the surface of the intestinal wall and directly dissecting the intestinal canal, both of which aim to expel the contents of the intestinal lumen. The traditional operation method is to place the open intestinal tube or severed intestinal tube in a clean bag, and then gradually discharge the intestinal contents into the clean bag by squeezing with both hands. This traditional method of operation has brought the following clinical problems. First of all, the clean bag has a large opening, and the intestinal tube is placed in the clean bag without airtightness, which leads to easy leakage of intestinal fluid and intestinal contents, resulting in contamination during the operation and postoperative infection; secondly, during the squeezing process, the operator's gloves , surgical gowns and the entire operating table are susceptible to contamination, and it is difficult to ensure a sterile environment; third, the bacteria in the intestinal cavity move at high speed during the extrusion process and spread in the air of the operating room, which makes it difficult to clean the operating room after surgery , resulting in the possibility of cross-infection with other operations; finally, the odor during the operation affects the subjective feelings of the operator, itinerant nurse and anesthetist.

In clinical practice, the above-mentioned problems can be solved to a certain extent by using the characteristics of the small opening of the laparoscopic sheath and the bandage at the opening to place the open intestine in it to form a relatively airtight simple device. However, the combination of the sheath and the intestinal tube is still relatively loose, easy to slip off or tied too tightly, resulting in difficulty in emptying during extrusion, which has limited effect during application.

Therefore, it is necessary to develop a better device to solve this clinical problem.
