[0041] The working principle of the present application is as follows:

[0042] Reference is made to the accompanying drawings Figures 1-6 Before inserting the fistula tube, two or three suture anchors 12 are used to fix the stomach wall of the patient relative to the abdominal wall in cooperation with a guide wire 11;

[0043] The suture anchor 12 is connected with the syringe, specifically, the needle plug 16 is connected with the nipple of the syringe;

[0044] The needle stem 17 is vertically pushed into the abdominal wall of the patient, the needle tip 20 penetrates the abdominal wall and the stomach wall, and stops after the needle stem 17 penetrates into the stomach cavity to a certain depth (the needle tip 20 guides the semicircular groove 19, the transition semicircular groove 19 and the needle stem 17 are transitioned through the excessive arc surface 18);

[0045] The syringe piston is pulled to extract the gastric juice, and then the syringe is pulled out;

[0046] The guide wire 11 is inserted into the puncture needle 13, specifically, the guide wire 11 enters from the suture anchor 12, passes through the needle stem 17, and then the anchor nail 15 is ejected after the guide wire 11 contacts the anchor nail 15; the anchor nail 15 is radially arranged along the needle stem 17, and the needle stem 17 and the semicircular groove 19 slide;

[0047] After the anchor nail 15 detaches from the puncture needle 13, the puncture needle 13 is withdrawn. During this process, the suture 14 and the anchor nail 15 either remain stationary or experience slight sliding (the suture 14 intersects the needle stem 17 and has a large friction between the abdominal wall and the gastric wall); even if the suture 14 slides, after the anchor nail 15 loses the support of the puncture needle 13, it is no longer perpendicular to the gastric wall and cannot return along the original path.

[0048] Pull the suture 14 to make the anchor nail 15 close to the gastric wall. Continue to pull the suture 14 to make the gastric wall and the abdominal wall approach and fix; fix the suture 14 to the patient's abdomen (using medical tape) and cut off some of the excess suture 14.

[0049] Repeat the above steps. After the guide wire 11 is pulled out, it can be reused. Multiple suture anchors 12 are used to fix the patient's gastric wall, usually two or three; the distribution of the suture anchors 12 needs to be uniform. When three suture anchors 12 are used, they are distributed in a "pin" shape; after the patient's gastric wall is fixed, continue with the operation of inserting the fistula tube.

[0050] In another embodiment of the present invention, refer to the appendix Figures 7-10 , before the suture anchor 12 is connected to the syringe:

[0051] When the suture 14 is clamped by the wire clip 24 and the anchor nail 15 is placed in the semi-circular groove 19, the suture 14 is in a taut state, always located on one side of the needle stem 17, and will not get entangled or bent or entangle other surgical tools.

[0052] After the suture anchor 12 is connected to the syringe (the doctor is holding the suture anchor 12 at this time): an additional step of flicking the suture 14 with a finger is performed. This step only takes a few seconds. The suture anchor 12 and the suture 14 return to the same state as in the previous embodiment, and the subsequent steps are the same as in the previous embodiment.

[0053] In any of the above embodiments, after the patient recovers, cut off the suture 14, and the anchor nail 15 falls into the gastric cavity. The anchor nail 15 can be discharged from the body along with defecation; in addition, the material of the anchor nail 15 can be designed as a degradable material, meeting a certain stiffness, and can be gradually decomposed under the action of gastric acid or pepsin, but it needs to be ensured that it will not be completely decomposed during the surgical treatment period.

[0054] In addition, it should be noted that when the shape of the groove (V-shaped groove 21) in the middle of the anchor nail 15 in the present invention is V-shaped, it has a good connection state with the suture 14, but it is not limited to V-shaped, and can be U-shaped, O-shaped, etc.; the semi-circular groove 19 at the puncture tip of the puncture needle 13 is also not limited to semi-circular, and can also be other shapes that meet the usage requirements, as long as it meets the requirement of placing the anchor nail 15.

[0055] In the description of the application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" and the like should be understood in a broad sense, for example, can be fixedly connected, can also be detachably connected, or integrally connected; can be mechanically connected, can also be electrically connected; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0056] The above is only an example and description of the structure of the application. Those skilled in the art can make various modifications or supplements to the described specific embodiments or replace them with similar ways, as long as they do not deviate from the structure of the application or exceed the scope defined by the claims.
