Detailed Description
The gastric fistula blocking device of the present utility model will be described in more detail below in conjunction with the schematic drawings, in which preferred embodiments of the present utility model are shown, it being understood that one skilled in the art may modify the utility model described herein while still achieving the beneficial effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.
The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. The advantages and features of the present utility model will become more apparent from the following description. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.
As shown in fig. 1 and 2, an embodiment of the present utility model proposes a gastric fistula plugging device comprising a head portion 1, a tail portion 2, and a mesh waist portion 3 fixedly disposed between the head portion 1 and the tail portion 2;
the middle position of the reticular waist 3 is provided with a supporting sealing air bag 4, the supporting sealing air bag 4 is annular and fixedly connected with the reticular waist 3, the supporting sealing air bag 4 is linearly distributed in the absence of air pressure, the supporting sealing air bag 4 supports and bulges the reticular waist 3 when being pressurized and is in fit contact with the inner wall of the gastric fistula, and two ends of the supporting sealing air bag 4 are respectively fixedly connected with the head part 1 and the tail part 2.
In this embodiment, the plugging device presents the straight line state when initial state, and medical personnel carries plugging device to patient's stomach fistula position department, carries out pressurization to support seal gasbag 4 and aerifys, and support seal gasbag 4 pressurization is inflated the back, supports seal gasbag 4 bulge, props up net waist 3 intermediate position department for net waist 3 middle and stomach fistula inner wall closely laminate, support seal gasbag 4 simultaneously and form the sealing layer between head 1 and afterbody 2, thereby reach the effect of shutoff stomach fistula.
In one embodiment, the mesh waist 3 is made of nitinol wires. The nickel-titanium alloy wire can bear great deformation and also can maintain elasticity. When the plugging device reaches the treatment part of the patient, the plugging device is driven by the supporting and sealing air bag 4 and matched with the reticular waist 3, so that the middle part of the reticular waist 3 is bulged, and the plugging of the gastric fistula is realized.
Furthermore, the outer sides of the head part 1 and the tail part 2 are all arranged in an arc surface shape, and the two ends of the net-shaped waist part 3 are circumferentially distributed and fixedly connected with the head part 1 and the tail part 2.
