Problems solved by technology
The existing fixation methods all use a large-diameter tube to stretch the intestinal tract, thereby fixing the device inside the intestinal tract. This fixing method destroys the blood and nutrient supply of the intestinal tract, and makes the stretched place bear relatively high pressure. Great stress is not conducive to the recovery of the intestines
In addition, it is impossible for any suture method to completely butt the intestinal tract without any gaps. If the position of the stretch is closer to the anastomosis, the incomplete butt joint will be stretched apart, increasing the risk of intestinal fistula

The intestinal tract anastomosis device comprises an isolation tube and a supporting tube, a notch is formed in the upper end of the isolation tube, the notch is annular and corresponds to the anastomosis position, a guide bag is arranged in the isolation tube, the guide bag is filled with a wound binder and is of a double-layer thin film cylindrical structure, a plurality of openings are formed in the notch, and when the intestinal tract anastomosis device is not used, the opening of the notch is closed. The opening is sealed. An extrusion pipe is arranged at the end, close to the isolation pipe, of the supporting pipe, and the slight diameter of the extrusion pipe is smaller than the inner diameter of the isolation pipe. According to the anastomosis device, a wound can be firmly fixed, meanwhile, the device and the interior of the intestinal tract are firmly fixed within several days after an operation, and fistula is avoided, and the anastomosis device is prevented from falling off; the supporting tube is fixed far away from the anastomosis position, tissue near the wound is prevented from being expanded, and the wound is healed more easily; the isolating tube and the supporting tube are flexibly connected, so that the length of the device can be changed, the device conforms to peristalsis of the intestinal tract, and falling is avoided.
Description
technical field [0001] The invention relates to an intestinal anastomosis device, in particular to an anastomosis device that can facilitate the healing of a patient's wound and avoid intestinal fistula. Background technique [0002] With the accelerated pace of modern life and the influence of unhealthy eating habits, the incidence of intestinal diseases is also increasing year by year, and part of the intestine needs to be removed in severe cases. The commonly used anastomosis methods in the prior art are suture suture and tubular stapler suture. After suturing, it is necessary to hold the intestinal pair in contact with a tubular device to avoid leakage of intestinal solubles from the suture, resulting in immeasurable postoperative complications. . Existing anastomotic devices such as CN113974742A all adopt a bell-mouth or dumbbell-shaped structure, that is, the two ends of the device are large and the middle is small, and the large rings at both ends are supported at th...
