摘要
Provided is an esophageal stent weaving tooling and the application method thereof, wherein the tooling comprises a hollow metal tube (1) and a screw rod (201) which is sequentially sleeved with a short joint (203), a square tube (204) and a spring (205) from top to bottom in a penetrating manner, wherein the screw rod (21) penetrates through the hollow metal tube (1), one end of the spring (205) is limited by a limiting structure in the hollow metal tube (1), and the other end of the spring (205) is abutted against the end face of the square tube (204), the square tube (204) is inserted into the hollow metal tube (1), the short joint (203) and the square tube (204) are integrally formed and can slide along the screw rod (201). A distance of 2-5 mm is reserved between the short joint (203) and the hollow metal tube (1), the short joint (203) can be pressed according to weaving requirements to adjust the distance between the short joint (203) and the hollow metal tube (1), and after weaving is completed, the short joint (203) may be pressed down until the short joint (203) is tightly attached to the hollow metal tube (1) so as to conveniently take out the esophageal stent. Therefore, the supporting force of the esophageal stent may be improved, and the occurrence of breakage or filament breakage is avoided. The tooling is particularly suitable for degradable esophageal stents, ensuring the quality and efficiency for weaving the esophageal stents.
