Background technique

With the acceleration of urbanization in our country, great changes have taken place in people's diet structure, living environment, working style and psychological behavior, resulting in an increasing trend of colorectal diseases in our country, especially colorectal cancer, the new The number of morbidity and the number of deaths due to the disease are in the forefront of all malignant tumors. The first choice for the treatment of colorectal cancer is to surgically resect a section of the intestine including the tumor, and then anastomose the two ends to restore the continuity of the intestine. Since the colorectum is an organ that stores and transports feces, it contains a large Bacteria and toxins, patients undergoing colorectal surgery must perform the following strict bowel preparations before surgery, otherwise the anastomosis (that is, the junction of the two broken ends) will not heal smoothly, and anastomotic leakage will occur: First, 3 days before the operation Light liquid diet, fasting water 1 day before operation; second, take antibiotics sensitive to intestinal flora 3 days before operation, usually streptomycin or gentamicin plus metronidazole, to kill intestinal bacteria as much as possible. Pathogenic bacteria in the tract; the third is to take laxatives 1 day before the operation, and clean the enema 1 time before the night and the morning of the operation to remove the feces in the intestine as much as possible. The most important of these are oral laxatives and cleansing enemas. In addition, it is necessary to continue to fast for several days after the operation, use intravenous antibiotics to sterilize bacteria, supplement sufficient nutrients to promote tissue growth, and give albumin to high-risk patients. Even so, some patients still have anastomotic leakage, and eventually penetrate the abdominal wall to form Intestinal fistula is very difficult to treat, which significantly increases the physical and mental pain and financial burden of patients, significantly prolongs the hospital stay, and a small number of patients may also develop secondary systemic infection, sepsis, or even multiple organ failure and death. For doctors and patients It's all very unfortunate.

In our country, due to various factors, a considerable number of colorectal cancer patients have intestinal obstruction due to the tumor blocking the intestinal cavity when they are diagnosed. For these patients, the above-mentioned intestinal preparation cannot be performed. There is a large amount of feces in the intestinal tract during the operation. Sometimes, if the anastomosis is performed immediately after tumor resection, that is, primary anastomosis, the risk of anastomotic leakage is very high. If primary anastomosis is not performed, an artificial anus can only be made at the proximal end on the abdominal wall so that feces can be discharged from the body, and the distal end is closed. After at least 3 months, the intestinal inflammation and edema completely subside and the blood supply returns to normal. On the basis of sufficient intestinal preparation, another operation is performed, the artificial anus is also brought into the abdominal cavity, and the two broken ends are connected, which is called a second-stage anastomosis. Although this method is relatively safe, it also increases the patient's risk to a certain extent. pain and inconvenience.

So why not perform bowel cleansing during the operation? This is mainly determined by the anatomical structure of the colorectum in the human body. The abdominal cavity is a closed cavity surrounded by a layer of smooth peritoneum with a thickness of about 0.5 mm and similar to a plastic film. The peritoneum covers most of the internal organs in the abdominal cavity. This kind of coverage can be divided into complete coverage and partial coverage. The former is like stomach, For the small intestine, the peritoneum completely wraps it and extends to form the mesentery. They are in a relatively free state in the abdominal cavity and have great mobility. The operator can hold them in his hand and manipulate them at will. If the small intestine is obstructed, the operator can move it gradually. The small intestine is completely emptied by segmental extrusion; the latter is like the pancreas, the peritoneum only covers its front, its sides and back are fixed on the surrounding tissue, and cannot be moved, and the surgeon cannot treat it like the stomach and small intestine It is also held in the hand, and can only be touched and sensed with fingers. These two types are called intraperitoneal and interperitoneal organs, and there is another situation where the peritoneum has nothing to do with organs, such as the kidneys, which are buried deep in the connective tissue behind the peritoneum and are called extraperitoneal organs. For the colorectum, the cecum, ascending colon, descending colon, and upper rectum are interperitoneal organs, the transverse colon and sigmoid colon are intraperitoneal organs, and the lower rectum is an extraperitoneal organ, so the contents of the colorectum cannot be compared with the small intestine. It is emptied by squeezing segment by segment with the operator's hand. It is even more regrettable that there is currently no special instrument or device that can effectively remove the colorectal contents in clinical practice. Ordinary negative pressure suction devices are ineffective in this situation because they are easily blocked by feces and intestinal walls. During similar operations, the risk of anastomotic leakage can only be performed for one-stage anastomosis, or the second-stage anastomosis will cause the patient to bear the pain of operation and the inconvenience caused by the artificial anus.

Utility model content

In order to change the current situation that the intestinal contents cannot be removed during the operation of patients with colorectal obstruction, the utility model provides an intraoperative colon lavage tube, which has a liquid inlet channel, an air intake channel, a negative pressure channel and multiple air bags. The support function, liquid flushing function, airflow pushing function and negative pressure suction function are integrated into one body, which can wash the intestinal cavity and suck out the intestinal contents diluted into fluid state in time.

The design idea and technical principle of the utility model are to comprehensively utilize the supporting effect of the air bag, the effect of liquid flushing, the effect of airflow pushing and the effect of negative pressure suction to effectively remove feces in the intestinal cavity. The technical solution adopted by the utility model to solve the technical problem is that there are accompanying flushing pipes and air intake pipes on the main body of the suction pipe with certain rigidity and toughness, and the suction pipes, flushing pipes and air intake pipes are all separated by a certain distance. There are side holes leading to the outside, and air bags are distributed at certain intervals on the suction tube, and the positions of the side holes and the air bags intersect each other. The utility model is inserted into the intestinal cavity through the anus, the incision of the intestinal wall or the broken end of the intestine, and the surgeon uses his hands outside the intestinal wall to assist it to advance along the intestinal cavity, pass through the two left and right colon bends (ie, the hepatic flexure and the splenic flexure), and finally reach At the end of the cecum, the air bag is inflated to prop up the intestinal tube in sections, the flushing tube is connected to the infusion set or syringe for flushing, the air intake tube is connected to the hand-pinch inflatable ball to continuously deliver air to the intestinal cavity, and the suction tube is connected to negative pressure for suction. The irrigating liquid cleans the intestinal lumen by flushing, and the mixture after washing is limited to a small section of the intestinal lumen propped up and separated by the air bag, and then sucked out through the side hole of the suction tube. Nearly solid, also able to be eventually cleared.

The beneficial effect of the utility model is that washing the intestinal cavity to keep it in a clean state is beneficial to tissue growth and anastomosis healing; multiple airbags divide the intestinal tube into small sections to prop up and continuously deliver air into the intestinal cavity, which overcomes the common The single-lumen suction tube will deflate the intestinal tube and lose its inherent defect of suction; the joint action of air flow and water flow ensures that the tube is unimpeded. The utility model is suitable for patients undergoing colorectal surgery who have not prepared their intestines before the operation due to various reasons.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail.

In Figure 1, the suction tube (1) is made of a material with certain rigidity and toughness, which can well adapt to the curvature of the intestinal tract, and it is not easy to be sucked by negative pressure. The flushing tube (2) and the intake tube (3) are connected with The suction tube (1) accompanies and forms a common blind end at the end, and the flushing tube (2) and the air intake tube (3) are preferably located inside the suction tube (1) or outside the suction tube (1). On the flushing pipe (2) there are flushing pipe side holes (7) at regular intervals, on the air intake pipe (3) there are air intake pipe side holes (8) at regular intervals, on the suction pipe (1) at regular intervals The suction tube side hole (6) is distributed to lead to the outside world. The diameter of the suction tube side hole (6) should be large enough, preferably more than 0.5cm. If it is too small, it will be easily blocked by intestinal contents. The diameter of the flushing pipe side hole (7) can be slightly smaller, 0.1cm～0.2cm. On the suction tube (1) there are airbags (5) distributed at regular intervals, the distance between two adjacent airbags is 8cm-10cm, and the diameter of the airbags after inflating is 3cm-3.5cm, which can fully prop up the intestinal wall. The positions of the side hole (6), the flushing pipe side hole (7), the intake pipe side hole (8) and the air bag (5) intersect each other without overlapping, so that the flushing, air intake and suction effects can be maximized. At the initial part of the suction tube (1) there is an air bag injection port (4), which is an inward one-way valve structure with anti-leakage function or made of elastic material and can be automatically closed. Air can make all air bags (5) inflated. The hand-pinch inflatable ball (9) is movably connected with the air intake tube (3), and is used for continuously inputting air into the intestinal cavity during the operation to prop up the intestinal wall between two adjacent air bags (5).

Figure 2 shows the usage method of the utility model. Before inserting, apply lubricant such as paraffin oil to the end of the pipeline to reduce friction. There are two ways to insert into the intestinal cavity, one is through the anus, and the other is through the incision of the intestinal wall or the broken end of the intestine . Advance along the direction of the descending colon (13), transverse colon (12) and ascending colon (11), until the end of the cecum (10), near the opening of the appendix (14) and ileum (15). The operator can use the hand to guide outside the bowel wall, especially through the flexures of the sigmoid colon, splenic flexure, and hepatic flexure. Connect the air bag injection port (4) with a syringe after it is in place, and inflate the air bag (5) to make it prop up the intestinal wall. Connect the flushing liquid to the flushing tube (2), the hand-pinch inflatable ball (9) to the intake tube (3), and the flushing liquid and air enter the intestinal cavity through the side hole of the flushing tube (7) and the side hole of the intake tube (8) respectively. The irrigating fluid dilutes the intestinal contents to facilitate aspiration, and the air isolates the intestinal wall from the suction tube (1) without blocking the side hole of the suction tube (6). 1) Start negative pressure suction, and the diluted intestinal contents will be sucked out through the side hole (6) of the suction tube. During the suction process, keep flushing and inflating continuously. The state of expansion is appropriate. Through the joint action of airflow and water flow, the contents of the intestines can be more fully removed. During use, there is no need to worry that the intestinal tube will be over-inflated and ruptured, because excess flushing fluid and air will naturally flow out from between the air bag (5) and the intestinal wall due to pressure, and there is continuous negative pressure suction in the intestinal cavity. After use, first remove the negative pressure suction, then remove the flushing fluid and the hand-pinch inflatable ball (9), and finally connect the air bag gas injection port (4) with a syringe to deflate the air bag (5), and the suction tube (1) exits the intestinal cavity.

Of course, what needs to be specially explained here is that these drawings are all simplified schematic diagrams, and their main function is to reflect the core content such as the design idea and technical principle of the utility model, rather than limit the structure of the utility model, and the final structure of the utility model The form, especially the details, are not limited to the listed drawings. Under the situation of following the design idea and technical principle of the utility model, many modifications can be made to the above-mentioned embodiments, as long as they do not depart from the essence of the utility model, they should Belong to the protection scope of the present utility model, not list one by one here again.
