Detailed ways

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

Embodiment 1: As shown in Figures 1 to 5, an adjustable ileostomy catheter includes a catheter body 1, the catheter body 1 is a flexible tube with openings at both ends, and the hardness is about 85A. It can resist bending and will not collapse easily. The opening at the lower end of the tube body is in the shape of an oblique incision, so that it can be easily inserted into the intestinal tract during operation.

The upper portion of the outer wall of the catheter body 1 is provided with external threads, and is connected with a pressing piece 11 through threads.

The outer wall of the catheter tube 1 is also covered with a first balloon 12 and a second balloon 13, the first balloon 12 and the second balloon 13 are non-compliant balloons, which are not easy to leak after filling .

The first balloon 12 is sleeved on the outer wall of the lower end of the catheter tube body 1, the lower end of the first balloon 12 is cylindrical, and the upper end is wave-shaped, and the shape of the lower end of the first balloon 12 matches the oblique cut of the lower end of the catheter tube body. matching. In this way, the first balloon 12 can fit well with the lower end of the catheter tube body, preventing the tip of the tube body from being exposed and piercing the intestinal wall, causing discomfort; at the same time, the upper end is wave-shaped, which can relieve the long-term compression of the intestinal wall by the balloon. Thereby reducing the chance of intestinal necrosis.

The second balloon 13 is a hemispherical or spherical structure, and is sheathed on the outer wall of the catheter tube body 1 between the first balloon 12 and the pressing piece 11 . The second balloon 13 in the figure is hemispherical, and its side opposite to the pressing sheet 11 is a planar structure. The advantage of this is that it can better fit human tissue, and can more effectively fit the intestinal wall and abdominal wall together to promote adhesion. After the adhesion, leakage of intestinal fluid into the peritoneal cavity from here will no longer occur.

The upper section of the catheter body 1 is provided with a first injection port 121 and a second injection port 131, and the first injection port 121 communicates with the first balloon 12 through the first communication tube 122 and injects or draws water therefor. The second injection port 131 communicates with the second balloon 13 through the second communication tube 132 to inject or draw water therefrom. The first balloon 12 and the second balloon 13 can expand after injecting physiological saline, and can contract after pumping water.

It needs to be explained here that the second balloon 13 and the pressing tablet 11 may not be provided in the invention. The main function of the second balloon 13 and the pressing tablet 11 is to cooperate with each other to make the intestinal wall adhere to the abdominal wall and adhere to prevent the extravasation of intestinal fluid. In the abdominal cavity, in fact, we can directly sew the intestinal wall and the abdominal wall together, which can also make the intestinal wall stick to the abdominal wall and adhere to prevent the extravasation of intestinal fluid into the abdominal cavity and achieve the desired effect.

Embodiment 2: As shown in Fig. 2, Fig. 3, Fig. 4, and Fig. 5, on the basis of Embodiment 1, in order to solve the problem of dredging the obstruction of the pipe body, a flushing pipe can be set in the pipe of the catheter body 1 3. The lower end of the flushing pipe 3 is closed, and a section of the side wall at the lower end is provided with a plurality of water outlet holes 31 leading to the conduit body 1 . A third injection port 32 is provided on the upper section of the catheter tube body 1, and the third injection port 32 is connected with the flushing pipe 3 to inject or draw water therefrom.

As shown in Figures 2 to 5, the shape of the flushing pipe 3 is linear. In fact, the flushing pipe 3 can also be arranged in other shapes. The shape is better, because of the spiral design, the water outlet holes in the lower section can be set in a circular manner, so that water can be sprayed from all around, and the flushing effect is better.

The distances between the positions of the first injection port 121, the second injection port 131 and the third injection port 32 and the upper end of the catheter tube body 1 are not the same, thus the parts connected to each other can be judged according to the difference in the distance from the injection port to the tail end. Can be marked accordingly for identification.

As shown in Figure 7, it is the situation when the utility model is inserted into the abdomen of a human body after intestinal surgery. Among them, 41 is the skin layer, 42 is the fat layer, 43 is the muscle layer, 44 is the peritoneum and fascia, 45 is the cecum, 46 is the appendix, 47 is the colon, 48 is the ileum, and 49 is the ileocecal valve. The skin layer 41, fat layer 42, muscle layer 43, peritoneum and fascia 44 make up the abdominal wall. After partial colorectal resection, an adjustable ileostomy catheter can be placed in the terminal ileum to prevent anastomotic leakage. The specific steps are as follows: After colorectal surgery, the terminal ileum is lifted out of the abdomen through a small incision assisted by the abdominal wall (laparoscopic surgery) or a large incision in the middle and lower abdomen (open surgery), the intestinal wall is cut 10 cm away from the ileocecal, and the catheter is inserted. The lower end of the catheter tube 1 is inserted into the terminal ileum 48 through the ileocecal valve 49 to a depth such that the second balloon 13 can be completely placed into the cecum cavity. Then inject water into the second balloon 13 through the second injection port 131 to prevent the catheter from slipping or shifting. Physiological saline is injected into the first balloon 12 through the first injection port 121, and the amount of water injected is adjusted according to the diameter of the small intestine. After the first balloon 12 is inflated, it can block the flow of intestinal fluid to the distal intestinal cavity, and lead the intestinal fluid out of the body through the lower end of the catheter, so that the colon proximal to the anastomotic stoma remains empty and unloaded, ensuring normal healing of the anastomotic stoma. Finally, the second balloon 13 and the pressing tablet 11 placed outside the body cooperate with each other, so that the intestinal wall where the catheter passes is adhered to the abdominal wall and adhered to prevent extravasation of intestinal fluid into the abdominal cavity, and at the same time fix the catheter. If the catheter body is obstructed, physiological saline can be injected into the flushing tube 3 through the third injection port 32 to dredge it. The upper opening of the catheter tube body 1 can be connected with a drainage bag to recover the drained intestinal juice, and can also be connected with a negative pressure drainage device.

In order to conveniently control the on-off of the opening at the upper end of the conduit, a control valve 7 may be connected to the opening at the upper end of the conduit. When the catheter can be removed after clinical evaluation, the physiological saline in the first balloon 12 is evacuated to allow the intestinal fluid to flow to the distal colorectum again. When it is confirmed that the patient has no anastomotic leakage and the physical signs are normal, the normal saline in the second balloon 13 can be evacuated, and the catheter can be easily removed, the leakage is filled with vaseline gauze, the outer gauze is covered, and the abdominal belt is fixed by pressure . After 3 to 4 days, change the dressing, remove the vaseline gauze, and the leak is basically healed, just cover it with gauze.

Embodiment 3: In Embodiment 2, a flushing tube 3 is arranged inside the catheter body 1 , and then water is injected into the flushing tube 3 from the third injection port 32 to dredge the obstruction.

During actual assembly, the two locking blocks 521 are located on both sides of the locking protrusion 541 .

In this embodiment, when encountering obstruction, the unblocker can be connected to the upper opening of the catheter body, insert the helical blade 53 into the lumen, and then rotate the handle 51 to drive the helical blade 53 to rotate and dredge the pipe body. And because of the existence of the locking block 521 and the locking protrusion 541, the flow of intestinal fluid can be prevented when the blockage is unblocked.

It should be noted here that the dredge structure of this embodiment can be used in combination with the flushing pipe 3 structure of embodiment 1, so that the effect will be better.

In addition, as shown in FIG. 14 , a sub-lumen opening 14 may also be provided on the upper part of the catheter tube body 1 so as to form a Y-shaped sub-lumen structure on the upper part of the catheter tube body 1 .
