一种鼻窦支架的编织成型方法和由此获得的支架技术

一种鼻窦支架的编织成型方法，包括：提供丝线(21)；提供具有纵向中心轴(A)的编织工装(1)，该编织工装(1)包括彼此轴向间隔开的第一赋形部(11)和第二赋形部(12)，第一赋形部(11)设有n个第一锚点(1111、1112……111n)，第二赋形部(12)设有n个第二锚点(1211、1212……121n)；围绕着编织工装(1)的周向方向，单根丝线(21)以第一赋形部(11)上的第1个第一锚点(1111)为起点，跨过m1个顶点间距向第二锚点延伸，然后跨过m2个顶点间距向第一锚点延伸，完成第一个“V”字形编织路径，然后重复该“V”字形编织路径，直至回到第1个第一锚点(1111)以形成初始构型支架(2)，其中，初始构型支架(2)具有周长(C)和n个顶点，顶点间距为周长(C)除以n，m1和m2为0.5的整数倍，m1+m2之和为整数，且m1+m2之和不是n的约数的整数倍。通过上述编织成型方法所获得的鼻窦支架具有良好的形状适应性，特别适合于用作鼻腔内的自膨胀支架。

A method for knitting and shaping a sinus bracket and a bracket obtained therefrom.

A braiding forming method for a nasal sinus stent includes: providing silk thread (21); providing a braiding tool (1) with a longitudinal central axis (A), comprising a first shaped part (11) and a second shaped part (12) axially spaced from each other, and a first shaped part (11) having N first anchors (1111, 1112... 111n), the second shape part (12) has n second anchors (1211, 1212... Around the circumferential direction of the knitting tooling (1), the single thread (21) starts from the first first anchor point (1111) on the first shaped part (11), extends across the M 1 Vertex spacing to the second anchor point, then extends across the M2 vertex spacing to the first anchor point, completes the first V-shaped knitting path, and then repeats the word \V\. The initial configuration scaffold (2) has a circumference (C) and N vertices. The vertex spacing is an integral multiple of the circumference (C) divided by n, M1 and m2, and the sum of M1 + M2 is an integer. The sum of M1 + M2 is not an integral multiple of n. The nasal sinus stent obtained by the braiding method has good shape adaptability and is especially suitable for the self-expanding stent in the nasal cavity.
