[0026] When performing internal fistula surgery, a 3 cm long longitudinal incision was made on the wrist of the patient after local infiltration anesthesia, the subcutaneous tissue and fascia were separated, and the radial artery 1 and cephalic vein 2 were freed. Block the blood flow at the proximal end 10 of the vein with a blood vessel clamp, ligate the distal end 5 of the vein with silk thread, cut off the cephalic vein 2 at the proximal end of the ligation point, and rinse the lumen of the stumped end of the cephalic vein 2 with heparin saline. The dissociated radial artery 1 is clamped with two vascular clips respectively at the proximal end 9 of the artery and at the distal end 4 of the artery to block the blood flow. A section of artery was reserved between the two vascular clips, and a 6mm long longitudinal incision was made on the side wall of this section of artery, and the lumen of the artery was flushed with heparin saline. Next, the device is implanted, and the pi...
