[0021] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0022] Please refer to the attached Figure 1 The embodiment of the present invention provides a percutaneous gastric puncture fistula device, including a fistula tube 1, one end of which is fixedly connected to a feeding port 2, which is used for feeding, a stomach wall pressing plate 3 is fixedly connected to the periphery of the fistula tube 1, the stomach wall pressing plate 3 is used to contact with the stomach wall and fix the stomach wall, and an abdominal wall pressing plate 5 is also sleeved on the periphery of the fistula tube 1, which is used to fix the abdomen of the patient, and after cooperating with the stomach wall pressing plate 3, the fistula tube 1 is fixed as a whole. A fixing ring 4 is sleeved on the periphery of the fistula tube 1, and the position of the abdominal wall pressing plate 5 is fixed by the fixing ring 4. The outer edges of the stomach wall pressure plate 3 and the abdominal wall pressure plate 5 are bent toward the rear end of the fistula tube 1. After the installation of the fistula tube 1 is completed, the stomach wall pressure plate 3 contacts the inner wall of the patient's stomach. Because the stomach wall pressure plate 3 and the abdominal wall pressure plate 5 have a certain curvature, the contact area and friction between the stomach wall pressure plate 3 and the abdominal wall pressure plate 5 and the stomach wall and the abdominal wall are increased. The bending angle of the stomach wall pressure plate 3 and the abdominal wall pressure plate 5 is not large, which will not cause too much pain to the patient. After the fistula tube 1 is fixed with a smaller clamping force, it will not cause too much additional damage when the fistula tube 1 is used, thereby reducing the pain of use for the patient.

[0023] A pipe 6 is fixedly connected to the bottom of the fistula tube 1. After the installation of the fistula tube 1 is completed, external instruments can enter the patient's gastric cavity through the pipe 6, and the gastric cavity situation can be directly observed without reinserting the gastroscope from the oral cavity. The end of the fistula tube 1 away from the feeding port 2 is sleeved with a plug 2 8, and the port of the fistula tube 1 is blocked by the plug 2 8. The end of the pipe 6 away from the feeding port 2 is sleeved with a plug 1 7, and the port of the pipe 6 is blocked by the plug 1 7. The outer edges of the stomach wall pressing plate 3 and the abdominal wall pressing plate 5 are provided with multiple notches 9. When the patient's abdominal wall and stomach wall are in contact with the abdominal wall pressing plate 5 and the stomach wall pressing plate 3, a certain shape of deformation will occur, and these deformations will remain in the middle of the notch 9, which can ensure the friction between the stomach wall pressing plate 3 and the abdominal wall pressing plate 5 and the patient, and increase the contact area, making the installation more stable.

[0024] Please refer to the attached Figure 2 -Attached Figure 8 As part of the present application, this embodiment also provides a percutaneous gastrostomy system, including: Puncture module: used to penetrate the skin and abdominal wall, create a channel to the stomach, and guide the fistula tube 1 to the stomach cavity; the puncture module is a device specially used to penetrate the skin and abdominal wall, and its purpose is to create a channel so that the guide fistula tube 1 can be inserted into the stomach cavity. During the operation, the module will pass through the puncture points of the skin and abdominal wall, so that the fistula tube 1 can smoothly enter the stomach.

[0025] The puncture module includes: Puncture needle: The needle has a sharp tip and is used to pierce the skin and abdominal wall, thereby creating a passage to the stomach, providing an initial passage for subsequently guiding the fistula tube 1 into the gastric cavity; the puncture needle can be made of stainless steel or high-strength alloy material to ensure that it has sufficient strength and durability. This is existing technology and will not be described in detail here.

[0026] Guide needle: After the puncture needle penetrates the abdominal wall, the guide needle will gradually expand the channel created by the puncture needle and guide the fistula tube 1 accurately into the gastric cavity; the guide needle has a gradually tapering design to ensure that it does not cause excessive damage to the tissue when passing through the abdominal wall. This is existing technology and will not be described in detail here.

[0027] Fistula tube 1: Fistula tube 1 is connected to the other end of the introducer needle and can be inserted into the created channel, thereby establishing a stable channel to the gastric cavity.

[0028] A fixing module, using a stomach wall pressing plate 3, a fixing ring 4 and an abdominal wall pressing plate 5, is used to fix the position of the fistula tube 1; The fixed module includes: Gastric wall pressure plate 3: The main function of this component is to clamp and fix the device on the gastric wall by means of the pressure on its surface, so as to maintain the position of the fistula tube 1 and prevent it from moving or falling off during gastric peristalsis or daily activities; The fixing ring 4 can surround the fistula tube 1 and the stomach wall pressing plate 3 to provide additional support and fixation, further enhance the stability of the device, and firmly fix the fistula tube 1 in place to prevent it from moving or rotating; Abdominal wall pressure plate 5: used to clamp and fix the device on the abdominal wall to ensure that the fistula tube 1 does not move or slip out. The design of the abdominal wall pressure plate 5 takes into account the physiological structure of the human abdomen, so that it can fit closely with the surrounding tissues to ensure the stability and safety of the device; The combined use of the fixing modules enables the fistula tube 1 to be firmly fixed in a predetermined position, ensuring its stability and safety throughout the treatment process. At the same time, the outer edges of the stomach wall pressure plate 3 and the abdominal wall pressure plate 5 are bent toward the rear end of the fistula tube 1. Because the stomach wall and abdominal wall of the human body are both protruding outward in an arc shape, the stomach wall pressure plate 3 and the abdominal wall pressure plate 5 are designed to be in a shape opposite to their arc. When the fistula tube 1 is installed, the contact area and friction between the stomach wall pressure plate 3 and the abdominal wall pressure plate 5 and the stomach wall and the abdominal wall can be increased. The bending angle of the stomach wall pressure plate 3 and the abdominal wall pressure plate 5 is not large, which will not cause too much pain to the patient. After the fistula tube 1 is fixed using a smaller clamping force, it will not cause too much additional damage when the fistula tube 1 is used, thereby reducing the pain of use for the patient.
