Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a stent and a stent weaving method. Background Technology

[0002] The most common braided brackets on the market are of two types: Cross type and Hook type.

[0003] Cross-type stents are made by winding and weaving filaments around the circumference of a mold. When the filaments reach the top of the stent, they bend in the opposite direction at a certain angle. The filament paths between the two ends of the stent do not bend in the opposite direction. The advantage of cross-type stents is that they are easy to assemble, but they have a large shrinkage rate (the length of the stent is significantly reduced after it is released from the sheath and expands) and poor flexibility (the greater the external force required to bend the stent, the worse its flexibility, and it cannot adapt to different degrees of curvature in the intestine).

[0004] Hook-type stents are constructed by repeatedly bending the stent from one end to the other, connecting them through a "V"-shaped structure. The disadvantage of hook-type stents is that they are difficult to assemble (because the interlocking threads overlap, increasing the stent's outer diameter and making it difficult to insert into the delivery system), but their advantages include low shrinkage (the stent's length does not decrease significantly after being released from the sheath) and good flexibility (the less force required to bend the stent, the better its flexibility, allowing it to adapt to different degrees of intestinal curvature).

[0005] If the stent is not easy to assemble, it increases the difficulty of assembling the stent into the delivery device and makes it difficult to operate; a large shortening rate can easily lead to difficulty in precise positioning during the operation, increasing the difficulty of the operation. At the same time, if the positioning is not proper, the stent is prone to displacement and blockage, and will bring a series of complications; a stent with insufficient flexibility cannot adapt to the intestinal environment with different degrees of curvature, which can easily lead to damage to the intestinal wall or cause intestinal obstruction.

[0006] Therefore, developing a stent that is easy to assemble, has a small shrinkage rate, and is flexible is a problem that needs to be studied. Summary of the Invention

[0007] Therefore, it is necessary to provide a bracket and bracket weaving method that are easy to assemble, have a small shrinkage rate and good flexibility to address the above-mentioned technical problems.

[0009] The intersection with the positioning pin is called the braiding position. Starting from one of the braiding positions, the wire is moved up and down in a V-shape between two rows until the bracket of the required length is formed, and the wire passes through all the intersections.

[0010] Wherein, the inflection points of all the V-shapes are located at the braiding position and wrapped around the positioning pin; if a positioning pin has two opposing V-shapes, then the two opposing V-shapes hook each other;

[0011] During the weaving process, the yarn interweaves and passes through the already woven paths.

[0082] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0083] This application provides a braiding method for a support structure, which employs a cylindrical clamp. The cylindrical clamp is evenly divided into multiple rows along the axial direction and into multiple columns along the circumferential direction. Each row intersects with each column to form an intersection point, and positioning pins for winding wires are provided at at least some of the intersection points.

[0084] The weaving method includes the following steps: The intersections with positioning pins are referred to as weaving positions. Starting from one of these weaving positions, the wire is moved in a V-shape, bending up and down between two rows, until a support of the required length is formed, and the wire passes through all the intersections; wherein the inflection points of all the V-shapes are located at the weaving positions and are wrapped around the positioning pins; if a positioning pin has two opposing V-shapes, the two opposing V-shapes hook together (e.g., ...). Figure 36 During the weaving process, the yarn interweaves and passes through the already woven paths (e.g., ...). Figure 37 ).

[0085] Reference Figure 35 The braided path of the wire forms a support with multiple diamond-shaped grids 30. Please refer to the above. Figure 36 , 37 In the rhombus grid 30 located on a partial column, one of the upper vertices 310 and the lower vertices 320 is a hook structure and the other is an interwoven structure. Figure 35 The dashed lines L1, L2, L3, and L4 shown pass through a column of rhombus-shaped grids 30. In the columns containing L1 and L4, one or all of the upper vertices 310 and lower vertices 320 of some or all of the grids have a hook-and-loop structure, while the other has an interwoven structure. In the column containing L2, all the upper vertices 310 and lower vertices 320 of the rhombus-shaped grids 30 have hook-and-loop structures. In the column containing L3, all the upper vertices 310 and lower vertices 320 of the rhombus-shaped grids 30 have an interwoven structure.

[0086] Using the above stent weaving method, the wire is bent up and down between the intersections of two rows in a V shape until a stent of the required length is woven, and the wire passes through all the intersections. The inflection point of the V shape is located at the weaving position and winds around the positioning pin at the weaving position. If there are two V shapes in opposite directions on one positioning pin, the two V shapes in opposite directions are hooked to each other. During the weaving process, the wire interweaves up and down between the already woven paths, and a stent with multiple diamond-shaped meshes can be obtained. In some columns of this stent, two axially adjacent diamond-shaped meshes are connected by a hooking structure, and some are connected by an up-and-down interweaving structure. Compared with the stents of the traditional Cross type or Hook type structures, the stent obtained by using the weaving method of the embodiment of the present application has the advantages of being easy to assemble, having a small shrinkage rate, and good flexibility at the same time.

[0087] Further, in one embodiment, starting from the first row of all rows, all rows are divided into multiple S cycles arranged in sequence, and the last row of one S cycle is used as the first row of the next S cycle. At the same time, starting from the first row of all rows, all rows are divided into multiple M cycles arranged in sequence, and the last row of one M cycle is used as the first row of the next M cycle. The wire includes a first wire 10 and a second wire 20. The weaving method includes the following steps: Using one weaving position as the starting point for weaving the first wire, making the first wire bend up and down between the first row and the last row of each S cycle in a first V shape, and finally passing through half of all the intersections. Using another weaving position as the starting point for weaving the second wire, making the second wire bend up and down between the first row and the last row of each M cycle in a second V shape, and finally passing through the remaining half of all the intersections. Wherein, one S cycle includes n + 1 rows. One M cycle includes m + 1 rows. The first V shape spans 2n + 1 intersections on the same row. The second V shape spans 2m + 1 intersections on the same row. Wherein, n and m are both positive integers, and m < n. Optionally, 2 ≤ n ≤ 4, 1 ≤ m ≤ 3. The double wires are woven in different-sized V shapes respectively. The weaving path of the first wire 10 is a first net with large diamond-shaped meshes in one layer, and the weaving path of the second wire 20 is a second net with small diamond-shaped meshes in one layer. The weaving path of the first net and the weaving path of the second net are interwoven up and down to obtain a stent with smaller diamond-shaped meshes, and the smallest diamond unit is the above-mentioned diamond-shaped mesh 30.

[0088] For clear description, the first, second,... of the cycles mentioned below have a front-back order. For example, the first M cycle and the second M cycle mean that the first M cycle on the cylindrical fixture is located above the second M cycle. The first end point, the second end point,... are only for distinguishing different names and do not represent an order.

[0089] Furthermore, in one embodiment, the weaving method includes the steps of: starting from the first row of all rows, dividing all rows into a plurality of sequentially arranged cycles, with the last row of one cycle serving as the first row of the next cycle. Each cycle has at least two rows;

[0090] Step 110: Using the intersection of the first row and any column as the starting point of the first cycle, move the wire in a V-shape between the first row and the last row of the first cycle until the wire returns to the starting point of the first cycle.

[0091] Step 120: Wrap the wire from the beginning of the first cycle along half of the first braided V-shape to the last row of the first cycle to form a reinforcing rib;

[0092] Step 130: Using the current intersection of the wires as the starting point of the second cycle, repeat steps 110 and 120 until the braided support reaches the required length.

[0093] The bracing method of this embodiment produces a support frame with reinforcing ribs, which can axially strengthen the support frame and thus reduce its axial shortening. (Refer to...) Figure 1-9 The support structure is constructed using double-wire braiding. The first wire 10 is braided to form a first mesh with a first reinforcing rib 110, and the second wire 20 is braided to form a second mesh with a second reinforcing rib 210. The braided wires of the first mesh and the braided wires of the second mesh are interwoven vertically to form a support structure with two reinforcing ribs.

[0094] Furthermore, in another embodiment, the weaving method includes the following steps: starting from the first row of all rows, dividing all rows into multiple cycles arranged in sequence, with the last row of one cycle serving as the first row of the next cycle, and each cycle having at least 2 rows;

[0095] Step 210: Using any intersection point on the first row of the initial cycle as the starting point of the initial cycle, move the wire in a V-shape, bending up and down between the first and last rows of the initial cycle, until the wire moves to the end point of the initial cycle; the end point refers to the intersection point on the last row of the current cycle that is passed before the wire returns to the starting point of the current cycle and belongs to the same V-shape as the starting point of the current cycle; the initial cycle is any cycle;

[0096] Step 220: Take the current intersection of the wires as the starting point of the next cycle (the end point of the previous cycle is the starting point of the next cycle), repeat step 210 until the wires move to the end point of the last cycle.

[0097] Step 230: Make the wire pass sequentially from the end point of the last cycle through the end points of each previous cycle until the wire returns to the end point of the starting cycle.

[0098] Step 240: Move the wire directly to the starting point of the initial cycle.

[0099] Furthermore, in the above embodiment, the starting period is the first period, and at the end of step 240, the bracket obtained by the wire braiding reaches the required length.

[0100] Furthermore, in the above embodiments, the starting cycle is the second cycle; the weaving method further includes the following steps:

[0101] Step 250: Taking the current intersection of the wires as the starting point of the first cycle, move the wires in a V-shape between the first row and the last row of the first cycle until the wires return to the starting point of the first cycle, and the bracket woven from the wires reaches the required length.

[0102] Furthermore, in the above embodiments, the starting period is any period between the third period and the third-to-last period; the weaving method further includes the following steps:

[0103] Step 261: Using the current intersection of the wires as the starting point of the previous cycle of the starting cycle, move the wires in a V-shape between the first and last rows of the previous cycle until the wires move to the second endpoint of the previous cycle; the second endpoint refers to the intersection of the wires on the first row of the current cycle, which is the same V-shape as the starting point of the current cycle, and is passed through before the wires return to the starting point of the current cycle.

[0104] Step 262: Using the current intersection of the wires as the starting point of the previous cycle, repeat step 261 until the wires move to the end point of the first cycle.

[0105] Step 263: Make the wire pass sequentially from the end point 2 of the first cycle through the end point 2 of each subsequent cycle until the wire returns to the end point 2 of the previous cycle of the starting cycle.

[0106] Step 264: Move the wire directly to the starting point of the previous cycle of the starting cycle.

[0107] Reference Figure 16-21In this embodiment, the braiding method begins with the wires braiding in a V-shape until the last cycle. Then, the wires return to the starting point of the initial cycle in an interlacing manner. Depending on the initial cycle, it is then determined whether to continue braiding upwards in the same pattern to achieve the required length of the support. After braiding, there are no reinforcing ribs, resulting in a smaller outer diameter of the compressed support, easier assembly, better flexibility, and a simpler braiding process. For a double-wire braided support, both the first wire 10 and the second wire 10 can be braided using this method.

[0108] Furthermore, in the above embodiments, the starting period is any period between the third period and the third-to-last period; the weaving method further includes the following steps:

[0109] Step 271: Using the current intersection of the wires as the starting point of the previous cycle of the starting cycle, move the wires in a V-shape between the first and last rows of the previous cycle until the wires move to the fourth endpoint of the previous cycle; the fourth endpoint refers to the intersection of the wires on the first row of the current cycle, which is a different V-shape from the starting point of the current cycle, before the wires return to the starting point of the current cycle.

[0110] Step 272: Using the current intersection of the wire as the starting point of the previous cycle, repeat step 371 until the wire moves to an intersection in the first row of the second cycle.

[0111] Step 273: Taking the current intersection of the wires as the starting point of the first cycle, move the wires in a V-shape, bending up and down between the first and last rows of the first cycle, until the wires return to the starting point of the first cycle; the braided support reaches the required length.

[0112] Step 274: Using the current intersection of the wires as the return start point of the second cycle, the wires are moved up and down in a V-shape between the first and last rows of the second cycle until the wires return to the start point of the second cycle.

[0113] Step 275: Using the current intersection of the wires as the return start point of the third cycle, repeat step 274 until the wires move to the start point of the initial cycle.

[0114] If the starting cycle is the third cycle, the weaving ends in step 274; if the starting cycle is any cycle between the fourth cycle and the third to last cycle, the weaving ends in step 275.

[0115] Reference Figure 16-21In this embodiment, the weaving method begins with the yarn in a V-shape until the last cycle, and then the yarn returns to the starting point of the initial cycle in an interlacing manner. (Refer to...) Figure 10-15 The braiding process begins from the cycle preceding the starting cycle and continues until the first cycle. Then, the wires are braided in a V-shape back to the beginning of the cycle preceding the starting cycle to achieve the required length of the support. This means the braiding pattern in cycles below the starting cycle differs from that in cycles above the starting cycle. After braiding, there are no reinforcing ribs, resulting in a smaller outer diameter of the compressed support, easier assembly, better flexibility, and a simpler braiding process. For a double-wire braided support, both the first wire 10 and the second wire 20 can be braided using this method.

[0116] Furthermore, in another embodiment, the weaving method includes the following steps: starting from the first row of all rows, dividing all rows into multiple cycles arranged in sequence, with the last row of one cycle serving as the first row of the next cycle, and each cycle having at least 2 rows;

[0117] Step 310: Using any intersection point in the initial cycle as the starting point of the initial cycle, move the wire in a V-shape, bending up and down between the first and last rows of the initial cycle, until the wire moves to the third endpoint of the initial cycle; the third endpoint refers to the intersection point on the last row of the current cycle that is passed before the wire returns to the starting point of the current cycle and is a different V-shape from the starting point of the current cycle; the initial cycle is any cycle;

[0118] Step 320: Using the current intersection of the wires as the starting point of the next cycle, repeat step 310 until the wires move to the endpoint three on the last row of the penultimate cycle;

[0119] Step 330: Using the current intersection of the wires as the starting point of the last cycle, move the wires in a V-shape between the first and last rows of the last cycle until the wires return to the starting point of the last cycle.

[0120] Step 340: Using the current intersection of the wires as the return start point of the penultimate cycle, the wires are moved up and down in a V-shape between the first and last rows of the penultimate cycle until the wires return to the start point of the penultimate cycle.

[0121] Step 350: Using the current intersection of the wires as the return start point of the third to last cycle, repeat step 340 until the wires move to the start point of the initial cycle.

[0122] Furthermore, in the above embodiment, the starting period is the first period, and at the end of step 350, the bracket woven from the wire reaches the required length.

[0123] Furthermore, in the above embodiments, the starting cycle is the second cycle; the weaving method further includes the following steps:

[0124] Step 360: Taking the current intersection of the wires as the starting point of the first cycle, move the wires in a V-shape between the first row and the last row of the first cycle until the wires return to the starting point of the first cycle, and the bracket woven from the wires reaches the required length.

[0125] Furthermore, in the above embodiments, the starting period is any period between the third period and the third-to-last period; the weaving method further includes the following steps:

[0126] Step 371: Using the current intersection of the wires as the starting point of the previous cycle of the starting cycle, move the wires in a V-shape between the first and last rows of the previous cycle until the wires move to the fourth endpoint of the previous cycle; the fourth endpoint refers to the intersection of the wires on the first row of the current cycle, which is a different V-shape from the starting point of the current cycle, before the wires return to the starting point of the current cycle.

[0127] Step 372: Using the current intersection of the wire as the starting point of the previous cycle, repeat step 371 until the wire moves to an intersection in the first row of the second cycle.

[0128] Step 373: Taking the current intersection of the wires as the starting point of the first cycle, move the wires in a V-shape between the first and last rows of the first cycle until the wires return to the starting point of the first cycle; the braided support reaches the required length.

[0129] Step 374: Using the current intersection of the wires as the return start point of the second cycle, the wires are moved up and down in a V-shape between the first and last rows of the second cycle until the wires return to the start point of the second cycle.

[0130] Step 375: Using the current intersection of the wires as the return start point of the third cycle, repeat step 374 until the wires move to the start point of the initial cycle.

[0131] If the starting cycle is the third cycle, the weaving ends in step 374; if the starting cycle is any cycle between the fourth cycle and the third to last cycle, the weaving ends in step 375.

[0132] Reference Figure 10-15 In this embodiment, the braiding method begins with a V-shaped weaving pattern until the last cycle, then the wires return in a V-shaped pattern to the starting cycle. Depending on the starting cycle, it is determined whether to continue braiding upwards in the same pattern to achieve the required length of the support. After braiding, there are no reinforcing ribs, resulting in a smaller outer diameter of the compressed support, easier assembly, better flexibility, and a simpler braiding process. For a support using double-wire braiding, both the first and second wires can be braided using this method.

[0133] Furthermore, in the above embodiments, the starting period is any period between the third period and the third-to-last period; the weaving method further includes the following steps:

[0134] Step 381: Using the current intersection of the wires as the starting point of the previous cycle of the starting cycle, the wires are moved up and down in a V-shape between the first and last rows of the previous cycle until the wires move to the second endpoint of the previous cycle; the second endpoint refers to the intersection of the wires on the first row of the current cycle, which is the same V-shape as the starting point of the current cycle, and is passed through before the wires return to the starting point of the current cycle.

[0135] Step 382: Using the current intersection of the wires as the starting point of the previous cycle, repeat step 261 until the wires move to the end point of the first cycle.

[0136] Step 383: Make the wire pass sequentially from the end point 2 of the first cycle through the end point 2 of each subsequent cycle until the wire returns to the end point 2 of the previous cycle of the starting cycle.

[0137] Step 384: Move the wire directly to the starting point of the previous cycle of the starting cycle.

[0138] Reference Figure 10-15 In this embodiment, the weaving method involves starting the weaving in a V-shape until the last cycle, and then returning the weaving in a V-shape to the starting cycle. (Refer to...) Figure 16-21 The braiding process begins from the previous cycle before the starting cycle and continues until the first cycle. Then, the wires interweave back to the beginning of the cycle before the starting cycle to achieve the required length of the support. That is, the braiding pattern in cycles below the starting cycle differs from the braiding pattern in cycles above the starting cycle. After braiding, there are no reinforcing ribs, resulting in a smaller outer diameter of the compressed support, easier assembly, better flexibility, and a simpler braiding process. For a double-wire braided support, both the first wire 10 and the second wire 20 can be braided using this method.

[0139] The following five specific embodiments illustrate the bracing method of this application.

[0140] Appendix Figure 1-35 The diagram shows a cylindrical clamp in its unfolded state. Dashed lines represent the completed wire movement path, while solid lines represent the wire movement path in the corresponding illustrated steps.

[0141] Specifically, Figures 1 to 34 The cylindrical clamp shown is evenly divided into 14 columns along the circumference and 15 rows along the axial direction.

[0142] To facilitate the description of the wire movement path, the following uses a combination of letters and numbers to represent the coordinates of intersections. A represents the column, B represents the row, and the column number increases from left to right and the row number from top to bottom. For example, A3B2 represents the coordinates of the intersection located in the third column and the second row. In the diagram, the intersection coordinates are indicated by a dot, representing a braided section with a positioning pin (positioning pins may be optional in some locations, see below for details); the absence of a dot at the intersection coordinates indicates that a positioning pin is not required at that location.

[0143] First Implementation Method

[0144] Please see Figures 1 to 5 This is a schematic diagram of the weaving process of the first wire 10 in the bracket weaving method of the first embodiment.

[0145] The weaving of the first wire includes the following steps:

[0146] S110. Take each n+1 rows as an S cycle, and start weaving the first wire downwards from any braiding position of the first row of the cylindrical clamp as the first starting point of the first S cycle. Move up and down in a first V-shape between the first row and the n+1 row until the first wire returns to the first starting point.

[0147] Specifically, refer to Figure 1-2 Each three rows constitutes an S-cycle (i.e., n=2, rows 1-3 and 3-5 are the first S-cycle and the second S-cycle, respectively, and so on; the first and second here represent the order). Starting from A1B1, the first wire moves towards A3B3, then moves upward to A5B1 from A3B3 as the inflection point to form the first first V-shape, and then moves downward to A7B3 from A5B1 as the inflection point to form the second first V-shape. The first and second first V-shapes are in opposite directions. Following the above pattern, the first wire moves between the first and third rows until it returns to A1B1. At this point, the first wire passes through half of all the intersections between the first and third rows (i.e., the braiding positions in the first and last rows of the first S-cycle are half-wound).

[0148] S120, the first wire is wound from the first starting point along half of the first first V-shape that has been woven to the (n+1)th row to form the first reinforcing rib 110.

[0149] Specifically, refer to Figure 3 The first wire returning to A1B1 is wound around the already braided first wire between A1B1 and A3B3 and then wound back to A3B3 to form a first reinforcing rib 110. The first reinforcing rib 110 can be exemplarily referenced from... Figure 38 and 39 However, not limited to the manner shown in the figure, the first wire is spirally wound around the first wire already braided in the aforementioned steps to form the first reinforcing rib 110. (Refer to...) Figure 38 The first reinforcing rib 110 is wrapped around two opposite first V-shaped sections at the same braiding position (see reference). Figure 4 (At point A3B3 in the middle). (Refer to...) Figure 39 As shown, the first reinforcing rib 110 is wound around the intersection of the wire (refer to...). Figure 3 (At point A2B2). The first reinforcing rib 110 can axially strengthen the support, thereby reducing the degree of axial shortening of the support.

[0150] S130. Using the current position of the (n+1)th row as the first starting point of the second S cycle, repeat steps S110 and S120 until the first wire is wound to the length required by the bracket.

[0151] Specifically, refer to Figure 3-4 The first wire, starting from A3B3 as the first starting point of the second S-cycle, moves to A5B5, then moves upwards to A7B3, forming the first V-shape of the second S-cycle, and then moves downwards to A9B5, forming the second V-shape of the second S-cycle. The first and second V-shapes are in opposite directions. Following this pattern, the first wire moves between the 3rd and 5th rows until it returns to A3B3. At this point, half of the braided sections in the 3rd and 5th rows are fully wound. (Refer to...) Figure 5 The weaving continues according to the above pattern until the first wire moves to A1B15, the first wire winds to the required length on the support and the weaving ends, forming a first mesh on the cylindrical clamp. The first mesh has a first reinforcing rib 110. Furthermore, if the same weaving position has two opposing V-shapes, the two opposing V-shapes form a hook structure (such as...). Figure 36 (As shown).

[0152] Figures 6 to 9 This is a schematic diagram illustrating the braiding process of the second wire 20 in the braiding method of the bracket in the first embodiment. The braiding of the second wire includes the following steps:

[0153] M110. Take each m+1 row as an M cycle. Start weaving the second wire from the first row of the cylindrical clamp, at any braiding position that the first wire has not passed, as the second starting point of the first M cycle. Move the second wire up and down in a second V-shape between the first row and the m+1 row until the second wire returns to the second starting point.

[0154] Specifically, refer to Figure 6-7 Each two rows are considered as an M-cycle (i.e., m=1, rows 1-2 and rows 2-3 are the first M-cycle and the second M-cycle, respectively, and so on, where first and second represent the order). Starting from A8B1, the second wire moves towards A9B2, then moves upward to A10B1 at A9B2 to form the first second V-shape, and then moves downward to A11B2 at A10B1 to form the second second V-shape. The first second V-shape and the second second V-shape are in opposite directions. Following the above pattern, the second wire moves between rows 1 and 2 until it returns to A8B1. At this point, the braided positions of rows 1 and 2 are fully wound, and the second wire passes through the intersection of the remaining half of rows 1 and 2.

[0155] M120, the second wire is wound from the second starting point along half of the first second V-shape that has been braided to the braiding position on the (m+1)th row to form the second reinforcing rib 210.

[0156] Specifically, refer to Figure 8 The second wire, returning to A8B1, wraps around the already braided second wire between A8B1 and A9B2 and then around A9B2 to form a second reinforcing rib 210. The second reinforcing rib 210 can be exemplarily referenced from... Figure 38 and 39 However, not limited to the manner shown in the figure, the second wire is spirally wound around the second wire already braided in the aforementioned steps to form a second reinforcing rib 210. (Refer to...) Figure 38 The second reinforcing rib 210 is wrapped around two opposite second V-shaped sections at the same braiding position (see reference). Figure 8 (At point A9B2 in the middle). (Refer to...) Figure 39 As shown, the second reinforcing rib 210 is wound around the intersection of the wire (refer to...). Figure 8 (The intersection of the second wire between A8B1 and A9B2 and the first wire between A7B3 and A9B1). The second reinforcing rib 210 can axially strengthen the support, thereby reducing the axial shortening of the support.

[0157] M130. Taking the current position of the (m+1)th row as the second starting point of the second M cycle, repeat steps M110 and M120 to wind the second wire to the required length of the bracket.

[0158] Specifically, refer to Figure 8-9The second wire, starting from A9B2 as the second starting point of the second M cycle, moves to A10B3, then moves upwards to A11B2, forming the first second V-shape in the second M cycle, and then moves downwards to A12B3, forming the second second V-shape in the second M cycle. The first and second second V-shapes are in opposite directions. Following this pattern, the second wire moves between the second and third rows until it returns to A9B2, at which point the braided positions on the second and third rows are fully wound. Braiding continues according to this pattern until the second wire reaches A8B15, at which point the braiding ends, forming a second mesh on the cylindrical clamp. The second mesh has second reinforcing ribs 210. The braided wires of the second mesh interweave with the braided wires of the first mesh to form the required support. Furthermore, if the same braided position has two opposing V-shapes, the two opposing V-shapes form a hook structure (e.g., Figure 36 (As shown).

[0159] In the first embodiment, both the first wire and the second wire are braided downwards from the first row to form two reinforcing ribs. Since the first starting point and the second starting point are symmetrical about the axis of the bracket, the two reinforcing ribs are symmetrically arranged to provide axial reinforcement to the bracket.

[0160] Optionally, the second wire can use other braided positions on the first row, excluding the first starting point (A1B1) and the symmetrical point of the first starting point (A8B1), as the second starting point. The resulting two reinforcing ribs can then reinforce the support at specific locations to meet specific needs in actual use. (Refer to...) Figures 31-34 The second wire begins to be braided from A2B1 in the first row, and its braiding pattern is the same as in this embodiment. The resulting bracket has two adjacent reinforcing ribs.

[0161] Second Implementation Method

[0162] The weaving method of the first wire in the second embodiment is the same as that in the first embodiment, and will not be described in detail here.

[0163] Figures 10 to 15 This is a schematic diagram of the weaving process of the second wire 20 in the bracket weaving method of the second embodiment.

[0164] The weaving of the second wire includes the following steps:

[0165] M210. Take each m+1 row as an M cycle. Take the second wire as the second starting point of the M cycle and start weaving downwards from any braiding position of the y2 row of the cylindrical clamp that the first wire has not passed. Move up and down in a second V-shape between the y2 row and the m+y2 row until the second wire is fully wrapped around the braiding positions of the y2 row and the m+y2 row.

[0166] Specifically, refer to Figure 10 Each two rows are considered as an M-cycle (i.e., m = 1). Taking A8B1 as the second starting point (i.e., y2 = 1), the second wire moves towards A9B2, then moves upward to A10B1 with A9B2 as the inflection point to form the first second V-shape. Then, with A10B1 as the inflection point, it moves downward to A11B2 to form the second second V-shape. The first second V-shape and the second second V-shape are in opposite directions. Following the above pattern, the second wire moves between the first and second rows to A14B1. At this point, the second wire has fully wound around the braided positions on the first and second rows.

[0167] M220, after the second wire is fully wound around the y2th row and the m+y2th row ( Figure 10 In the case of partial positioning pins on the second row (y2), the second wire is made to move from the second row (y2). Figure 10 The first row in the middle is different from any of the weaving positions at the second starting point. Figure 10 (A14B1) moves in a half-second V-shape to the weaving position on the m+y2th row. Figure 10 (A1B2).

[0168] Specifically, refer to Figure 10-11 If some braided positions in the first and second rows are fully wound (i.e., the second wire is not fully wound in all braided positions), the second wire is moved down from A14B1 to A1B2.

[0169] M230: Start weaving the second wire downwards from the current position of row m+y2 as the second starting point of the next M cycle. Repeat steps M210 and M220 until the second wire moves to the second starting point of row Ym (Y represents the total number of rows).

[0170] Specifically, refer to Figure 11-12 The second wire, starting from A1B2 as the second starting point of the next M-cycle, continues downwards to A2B3, then moves upwards to A3B2, following the same pattern until it reaches A7B2. From A7B2, it moves downwards to A8B3, and from A8B3, it continues downwards to A9B4, following the same pattern until it reaches the second starting point of the last M-cycle. Figure 12 (A1B14, i.e., Y=15).

[0171] M240: Move the second wire in a second V-shape between rows Ym and Ym until it returns to the second starting point of row Ym. That is, after the last M-cycle's weaving position is fully wound, return to the second starting point of that M-cycle, ready to begin upward weaving.

[0172] Specifically, refer to Figure 12-13The second thread begins its downward movement from A1B14, the second starting point of the last M cycle, to A2B15. Then, it moves upward to A3B14, using A2B15 as the inflection point, following the same pattern until it returns to A1B14. Furthermore, the two opposing V-shapes on the 14th row of the braid form a hook structure.

[0173] M250: The second wire is braided upwards and moves up and down in a second V-shape between the Y-2m row and the Ym row until the second wire wraps back to the second starting point of the penultimate M cycle. At this point, the braiding position of the penultimate M cycle is completely filled. Furthermore, if the same braiding position has two opposite V-shapes, the two opposite V-shapes form a hook structure.

[0174] Specifically, refer to Figure 14 The second wire starts weaving upwards from A1B14 and moves to A2B13. Then, it moves downwards to A3B14 with A2B13 as the inflection point. This process continues until it reaches A8B13, at which point all the weaving positions on the 13th row are completely filled.

[0175] M260, Repeat step M250 until the second wire wraps back to the second starting point of row y2; if y2 equals 1, the weaving of the second wire is completed; if y2 equals m+1, proceed to step M270; if y2 equals km+1 (k is a positive integer not equal to 1), proceed to steps M280a-M280f.

[0176] Figure 10-15 In one embodiment shown, y2 equals 1. The second wire is braided upwards past the second starting point of each M-cycle until it returns to the second starting point A8B1 of the first row of positioning pins. The second wire then ends its braiding, forming a second mesh on the cylindrical clamp. The second mesh has no second reinforcing ribs 210. The braided wires of the second mesh interweave vertically with the braided wires of the first mesh to form the desired support. Furthermore, if the same braided position has two opposing V-shapes, the two opposing V-shapes form a hook structure.

[0177] When y2 equals 1, it means the second wire starts weaving from the first row. After completing a portion of the weaving positions in each M-cycle, it begins weaving in the next M-cycle until the required length of the support is reached. This is the downward weaving of the wire. After completing the last M-cycle, the second wire can begin upward weaving, returning from the last M-cycle to the first M-cycle. During the upward weaving, the second wire completes the remaining weaving positions. It should be noted that the number of weaving positions completed by the second wire in each M-cycle's downward weaving can be the same or different.

[0178] In another embodiment, y2 equals m+1. After step M260, the second wire returns to the second starting point of the second M cycle, crossing the second starting point of the second M cycle, and winds itself in a second V-shape between the first and last rows of the first M cycle until it returns to the second starting point of the second M cycle. The remaining braided positions on the cylindrical clamp are filled, the second wire ends its braiding, and a second mesh is woven on the cylindrical clamp. The second mesh has no second reinforcing rib 210. The braided wires of the second mesh interweave with the braided wires of the first mesh to form the required support. Furthermore, if the same braided position has two opposing V-shapes, the two opposing V-shapes form a hook structure.

[0179] The specific steps are as follows: M270, the second wire is braided upwards between row y2-m and row y2, bending and moving up and down in a second V-shape until the second wire returns to the second starting point of row y2, thus completing the braiding of the second wire. That is, the second wire crosses the second starting point of row y2 and winds in a second V-shape between the first row and the last row of the first M cycle of the cylindrical clamp until it returns to the second starting point of row y2.

[0180] When y2 equals m+1, it means that the second wire starts to weave downwards from the second M cycle, wraps around the last cycle, and then weaves upwards until all weaving positions except the first M cycle are filled. Then it continues to weave upwards to fill the first M cycle, and the weaving is completed.

[0181] In one embodiment, y2 equals km+1 (k is a positive integer not equal to 1). That is, the second wire begins its downward weaving with any cycle from the third M-cycle down to the last cycle, then moves upwards back to the starting M-cycle, at which point at least two M-cycles remain unwoven. Following this pattern, the second wire continues upwards, weaving through a portion of an M-cycle before moving to the next M-cycle, until the first M-cycle is fully woven. Then it continues downwards until all weaving positions are filled, completing the weaving of the second wire. Furthermore, if the same weaving position has two opposing V-shapes, these two opposing V-shapes form a hook structure.

[0182] After the second thread returns to the initial M cycle, the specific steps of weaving are as follows:

[0183] M280a, causing the second wire to move up and down in a second V-shape between the y2-m row and the y2 row.

[0184] M280b, when the second wire is fully wound around the braided position of the y2-m row, moves the second wire from any braided position of the y2 row that is different from the second starting point to the y2-m row in a half-second V-shape.

[0185] M280c: Start the second wire from the current position of row y2-m as the new second starting point and repeat steps M280a and M280b until the second wire moves to the second starting point of row 1+m.

[0186] M280d causes the second wire to move up and down in a second V-shape between the 1+m row and the 1st row until the second wire returns to the second starting point of the 1+m row.

[0187] The pattern of steps M280a-M280d is similar to that of steps M210-M240, except that steps M210-M240 are downward knitting, while steps M280a-M280d are upward knitting.

[0188] M280e, the second wire is braided downwards between the 1+m row and the 1+2m row, moving up and down in a second V-shape until the second wire wraps back to the second starting point of the 1+2m row.

[0189] M280f, repeat step M280e to make the first wire wrap back to the second starting point of the y2 row, and complete the weaving of the second wire.

[0190] The pattern of steps M280e and M280f is similar to that of steps M250 and M260, except that steps M250 and M260 are downward knitting, while steps M280e and M280f are upward knitting.

[0191] y2 equals km+1 (k is a positive integer not equal to 1). After the second wire returns to the second starting point of the initial cycle, it needs to be braided upwards and then downwards until the remaining braiding positions on the cylindrical clamp are filled. The second wire ends its braiding, and a second mesh is woven on the cylindrical clamp. There is no second reinforcing rib 210 on the second mesh. The braided wires of the second mesh are interwoven with the braided wires of the first mesh to form the required support.

[0192] Compared to the first embodiment, the bracket woven in the second embodiment has only one reinforcing rib, resulting in a smaller outer diameter after compression, easier assembly, better flexibility, and a simpler weaving process. Furthermore, with the second embodiment, the second wire can be woven starting from any cycle.

[0193] In the embodiments described above, the first second V-shape formed by the second wire in each cycle can be an upright V-shape with the opening facing upwards. This upright V-shape is particularly necessary for embodiments where braiding begins from the first row of the cylindrical clamp. If the second wire begins braiding from the last row of cycle M, the first second V-shape can also be an inverted V-shape with the opening facing downwards, as shown in the reference section. Figure 27-30The second wire begins to be braided upwards from the braiding position on A4B3 (i.e., the first second V-shape is an inverted V-shape), and its braiding pattern is similar to that of this embodiment.

[0194] It should be noted that at some intersections, the second wire crosses directly without turning to another direction for weaving. Therefore, optionally, there is no need to set positioning pins for supporting the wires at these intersections (i.e., they are not used as weaving positions). In the embodiments listed in the second implementation, for example, positioning pins are not required at intersections such as A1B2, A8B3, and A8B13. In other words, the necessary positioning pins only need to be set at the inflection points of each V-shape.

[0195] Third Implementation Method

[0196] The weaving method of the first wire in the third embodiment is the same as that in the first embodiment, and will not be described in detail here.

[0197] Figures 16 to 21 This is a schematic diagram of the weaving process of the second wire 20 in the bracket weaving method of the third embodiment.

[0198] The weaving of the second wire includes the following steps:

[0199] M310. Take each m+1 row as an M cycle, and make the second wire start to weave downwards with the cylindrical clamp at any positioning pin of the y2 row that the first wire has not passed as the second starting point of the M cycle, and move up and down in a second V-shape between the y2 row and the m+y2 row.

[0200] Specifically, refer to Figure 16 Each two rows are considered as an M-cycle (i.e., m = 1). Taking A8B1 as the second starting point (i.e., y2 = 1), the second wire moves towards A9B2, then moves upward to A10B1 with A9B2 as the inflection point to form the first second V-shape. Then, with A10B1 as the inflection point, it moves downward to A11B2 to form the second second V-shape. The first second V-shape and the second second V-shape are in opposite directions. Following the above pattern, the second wire moves to A6B1 between the first and second rows. At this point, the braided position of the first row is fully wound.

[0201] M320, with the second wire fully wound around the y2th row of positioning pins, moves the second wire to the m+y2th row in half of the last second V-shape.

[0202] Specifically, refer to Figure 17 When the first row of braided sections is fully wound, the second wire is moved down from A6B1 to A7B2, and A7B2 may not have a positioning pin.

[0203] M330: Start weaving the second wire downwards from the current position of row m+y2 as the second starting point of the next M cycle. Repeat steps M310 and M320 until the second wire moves to the second starting point of the last M cycle.

[0204] Specifically, refer to Figure 17 The second wire, starting from A7B2 as the second starting point of the second M cycle, continues downwards to A8B3, then moves upwards to A9B2, using A8B3 as the inflection point. (Refer to...) Figure 18 Following the above pattern, move down to A5B2, then from A5B2 down to A6B3, using A6B3 as the second starting point of the third M cycle, and continue down to A7B4, referring to... Figures 19-20 This pattern continues until the second starting point A8B15 of the last M cycle is reached.

[0205] M340: Start weaving the second wire from the second starting point of the last M cycle upwards, so that the second wire passes through the second starting point of each M cycle in sequence until the second wire returns to the second starting point of row y2; if y2 equals 1, then the weaving of the second wire is completed; if y2 equals m+1, then execute M350; if y2 equals km+1 (k is a positive integer not equal to 1), then execute M360a-M360d.

[0206] Figure 16-21 In one embodiment shown, y2 equals 1. The second wire then moves upwards sequentially through the second starting point of each of the M cycles until it returns to the second starting point A8B1 of the first row. The second wire then completes its weaving, forming a second mesh on the cylindrical clamp. The second mesh has no second reinforcing ribs 210. The braided wires of the second mesh interweave with the braided wires of the first mesh to form the required support. Except for the first and 15th rows, the second starting point positions of the remaining rows may not have positioning pins.

[0207] In another embodiment, y2 equals m+1. After step M340, the second wire returns to the second starting point of the y2th row, crossing the second starting point of the y2th row, and wraps in a second V-shape between the positioning pins of the 1st and y2nd rows until it returns to the second starting point of the positioning pins of the y2th row. The remaining braiding positions on the cylindrical clamp are filled, and the second wire ends its braiding, forming a second mesh on the cylindrical clamp. The second mesh has no second reinforcing rib 210. The braided wires of the second mesh interweave with the braided wires of the first mesh to form the required support.

[0208] The specific steps are as follows: M350, make the second wire braid upward between the positioning pins of the 1st row and the y2nd row, bend up and down in the second V shape, until the second wire wraps back to the second starting point of the y2nd row, then the braiding of the second wire is completed.

[0209] In one embodiment, y2 equals km+1 (k is a positive integer not equal to 1). That is, the second wire starts from the third M-cycle and the M-cycles below it as the starting cycle, and starts weaving downwards from the second starting point of the starting cycle until it reaches the last row, then weaves upwards back to the second starting point of the starting cycle. At this point, there are still at least two M-cycles left to weave. Following the above pattern, the second wire also needs to start weaving upwards from the second starting point of the starting cycle, and after completing one cycle, it moves to the first row of that cycle to begin the previous cycle, until it reaches the first row, and then weaves downwards through the second starting points of each M-cycle until the second wire returns to the second starting point of the starting cycle, at which point the weaving of the second wire ends.

[0210] The specific steps are as follows:

[0211] M360a, the second wire is braided upwards between row y2-m and row y2, moving up and down in a second V-shape.

[0212] M360b, with the second wire fully wound around the y2th braid position, moves the second wire to the y2-mth row in half of the last second V-shape.

[0213] M360c: Start weaving the second wire upwards from the current position of row y2-m as the new second starting point, and repeat steps M360a and M360b until the second wire moves to the second starting point of the first M cycle.

[0214] The pattern of steps M360a-M360c is similar to that of steps M310-M330, except that steps M310-M330 are downward knitting, while steps M360a-M360c are upward knitting.

[0215] M360d: The second wire begins weaving downwards from the second starting point of the first cycle, and the second wire passes through the second starting point of each M cycle in sequence until the second wire returns to the second starting point of the initial cycle, thus completing the weaving of the second wire.

[0216] The pattern of step M360d is similar to that of step M340, except that step M340 is an upward weaving, while step M360d is a downward weaving.

[0217] y2 equals km+1 (k is a positive integer not equal to 1). After the second wire returns to the second starting point of the initial cycle, it needs to be braided upwards and then downwards until the remaining braiding positions on the circular clamp are filled. The second wire then finishes braiding, and a second mesh is woven on the cylindrical clamp. There is no second reinforcing rib 210 on the second mesh. The braided wires of the second mesh are interwoven with the braided wires of the first mesh to form the required support. Except for the first and fifteenth rows, the second starting point position of each of the other rows does not need to be set with a positioning pin.

[0218] Compared to the first embodiment, the bracket woven in the third embodiment has only one reinforcing rib, resulting in a smaller outer diameter after compression, easier assembly, better flexibility, and a simpler weaving process. Similar to the second embodiment, the third embodiment can also be woven starting from any cycle.

[0219] Fourth Implementation Method

[0220] Figures 22 to 26 This is a schematic diagram of the weaving process of the first wire 10 in the bracket weaving method of the fourth embodiment.

[0221] The weaving of the first wire includes the following steps:

[0222] S210. Take each n+1 rows as an S cycle, and start weaving the first wire upwards from any weaving position on the n+y1th row of the cylindrical clamp as the first starting point of the S cycle, and move up and down in a first V-shape between the y1th row and the n+y1th row.

[0223] Specifically, refer to Figure 22 Each three rows constitutes an S-cycle (n=2). Starting from A5B5 (y1=3), the first wire moves towards A7B3, then moves downwards to A9B5, forming the first V-shape, and then moves upwards to A11B3, forming the second V-shape. The first and second V-shapes are in opposite directions. This pattern continues until the wire reaches A13B5. At this point, the second wire is in the last row of the current cycle and has not yet returned to the first starting point.

[0224] S220. If the first wire has not been fully wound through half of the braiding positions of the y1th row and the n+y1th row, the first wire is moved down to the 2n+y1th row in a half-first V-shape from any braiding position of the n+y1th row that is different from the first starting point as the transition point.

[0225] Specifically, refer to Figure 22 , 23 If the second wire is in the last row of the current cycle and has not yet returned to the second starting point, move the first wire down from A13B5 to A1B7. A13B5 may not have a positioning pin.

[0226] S230. Take the current position of the first wire in the 2n+y1th row as the first starting point of the next S cycle, and repeat steps S210 and S220 until the first wire is moved to the first starting point of the last S cycle.

[0227] Specifically, refer to Figure 23 , 24The first wire starts at A1B7 as the first starting point of the next S-cycle and continues moving upwards to A3B5. Then, using A3B5 as the inflection point, it moves downwards to A5B7. This pattern continues until it reaches A9B7. Then, using A9B7 (A9B7 may not have a positioning pin) as the transition point, it moves downwards to A11B9. A11B9 becomes the first starting point of the next S-cycle, and the wire continues moving upwards to A13B7. This pattern continues until it reaches the first starting point of the last S-cycle. Figure 24 (A13B15).

[0228] S240, the first wire is moved up and down in a first V-shape between the first row and the last row (i.e., the Y-row positioning pin and the Yn-row positioning pin) in the last S cycle, so that the braiding positions of the Y-row and the Yn-row are both half-wound.

[0229] Specifically, refer to Figure 25 The first wire starts from the first starting point A13B15 of the last S cycle and continues to move upward to A1B13 (i.e., Y=15). Then, it moves downward to A3B15 with A1B13 as the inflection point. This pattern continues until it reaches the transition point A11B13 of the 13th row (i.e., the first row of the last S cycle). (A11B13 does not need to be equipped with a positioning pin.) At this point, the braiding positions of the 15th row and the 13th row (i.e., the first and last rows of the last S cycle) are both half-wound.

[0230] S250, Move the first wire upwards from the transition point of the first row (i.e., row Yn) of the last S cycle in a half-first V shape to the positioning pin of the first row (i.e., row Y-2n) of the penultimate S cycle.

[0231] Specifically, refer to Figure 25 , 26 The first wire moves from the transition point A11B13 of the 13th row to A13B11, and then moves down to A1B13 with A13B11 as the inflection point. This continues until it reaches the transition point A1B11 of the 11th row (A1B11 does not need to be equipped with a positioning pin). At this time, the braiding positions of the 13th and 11th rows (i.e. the first and last rows of the second to last S cycle) are both half-wound.

[0232] S260, Repeat steps S240 and S250 to make the first wire wind to the (n+y1)th row of positioning pins; if y1 equals 1, then execute S270; if y1 equals n+1, then execute S280; if y1 equals kn+1 (k is a positive integer not equal to 1), then execute S290a-S290h.

[0233] In one embodiment, y1 equals 1, then the first wire is woven upwards past the transition point of each row until it returns to the first starting point of the first S cycle, the first wire ends weaving, and a first net is woven on the cylindrical clamp, without the first reinforcing rib 110 on the first net.

[0234] When y1 equals 1, it means the first wire starts weaving from the last row of the first S-cycle. The first V-shape is an inverted V-shape with the opening facing downwards. After completing a portion of the weaving positions in each S-cycle, it begins weaving into the next S-cycle, continuing until the required length of the support is reached. This is the downward weaving of the wire. After completing the last S-cycle, the first wire can begin upward weaving, returning from the last S-cycle to the first S-cycle. During the upward process, the first wire completes half of the remaining weaving positions in all S-cycles. It should be noted that the number of weaving positions completed by the first wire in each downward weaving of an S-cycle can be the same or different.

[0235] The specific steps are as follows: S270, the first wire bends and moves up and down in a first V shape between the first row of positioning pins and the (n+1)th row of positioning pins, so that the braiding positions of the first row and the (n+1)th row are both half-wound, and the first wire returns to the first starting point of the first S cycle, completing the braiding of the first wire.

[0236] Figure 22-26 In one embodiment shown, y1 = n + 1 = 3. After step S260, the first wire returns to the 5th row, and the first wire crosses the transition point A13B5 of the 5th row. It is woven in a first V-shape between the 3rd and 5th rows until half of the weaving position of the 3rd and 5th rows is filled. The first wire is wound to the transition point A3B3 of the 3rd row, and the first wire crosses the transition point A3B3 of the 3rd row. It is woven in a first V-shape between the 1st and 3rd rows until it returns to A3B3. Finally, it crosses the transition point A3B3 and moves to A5B5. The weaving of the first wire ends, and a first net is woven on the cylindrical clamp. There is no first reinforcing rib 110 on the first net.

[0237] The specific steps are as follows:

[0238] S280. Move the first wire between row y1 and row y1+n in a first V-shape, bending up and down, so that half of the braiding positions in row y1 and row y1+n are fully wrapped; move the first wire from its current position in row y1 as a transition point, moving upwards in a half-first V-shape to row y1-n; move the first wire between row y1 and row y1-n in a first V-shape, bending up and down, so that half of the braiding positions in row y1 and row y1-n are fully wrapped; move the first wire from the transition point in row y1 downwards in a half-first V-shape back to the first starting point in row y1+n, completing the braiding of the first wire.

[0239] When y1 equals n+1, it means that the first wire starts to weave downwards from the second S cycle, and after completing the last S cycle, it weaves upwards until all weaving positions except the first S cycle are completed. Then it continues to weave upwards to complete the first S cycle, thus completing the weaving.

[0240] In one embodiment, y1 equals kn+1 (k is a positive integer not equal to 1), representing that the first wire begins its downward weaving from any S-cycle starting from the third S-cycle or any cycle below the third S-cycle until it is fully wound through the last cycle, then moves upwards to weave back to the starting S-cycle, at which point at least two S-cycles remain unwound. Following this pattern, the first wire also needs to weave upwards, filling a portion of the weaving positions in one S-cycle before moving to the previous S-cycle to weave, until the first S-cycle is fully wound, then moves downwards to weave until half of the weaving positions in all S-cycles are filled, completing the weaving of the first wire. Furthermore, if the same weaving position has two opposing V-shapes, the two opposing V-shapes form a hook structure. That is, the first wire begins its weaving from one of the weaving positions below the 2n+1th row as its first starting point until it reaches the last row, then moves upwards to weave back to the 2n+1th row, at which point at least 2n+1 rows of weaving positions remain unwound. According to the above rules, the first wire needs to be woven in the 2n+1th row. Before completing one S cycle, it moves to the previous S cycle to weave until it reaches the 1st row, and then weaves downwards until it returns to the first starting point of the initial cycle, thus completing the weaving of the first wire. The first net is woven on the cylindrical clamp, and there is no first reinforcing rib 110 on the first net.

[0241] After the first thread returns to the starting S cycle, the specific weaving steps are as follows:

[0242] S290a, the first wire is moved up and down in a first V-shape between the y1 row and the y1+n row, so that half of the braided position of the y1+n row is wrapped.

[0243] S290b: Using the current position of row y1 as a transition point, the first wire moves upward in a half-first V-shape to row y1-n.

[0244] 290c. The first wire is woven downwards from the current position of row y1-n as the new first starting point, and moves up and down in a first V-shape between row y1-n and row y1.

[0245] S290d, if the first wire has not been wound halfway around the positioning pins of row y1-n, the first wire is moved upward to row y1-2n from any braiding position of row y1-n that is different from its first starting point as the transition point.

[0246] S290e: Using the current position of the first wire in the y1-2n row as the new first starting point, repeat steps S290c and S290d until the first wire is moved to the first row.

[0247] Steps S290c-S290e follow a similar pattern to steps S210-S230, but the difference is that steps S210-S230 are downward weaving, while steps S290c-S290e are upward weaving.

[0248] S290f, causing the first wire to bend and move up and down in a first V-shape between the first row and the 1+n row, so that the braiding positions of the first row and the 1+n row are both half-wound.

[0249] S290g causes the first wire to move downwards from the transition point of row 1+n in a half-first V-shape to row 2n+1.

[0250] S290h, repeat steps S290f and S290g to make the first wire wrap back to the first starting point of the n+y1th row, thus completing the weaving of the first wire.

[0251] Steps S290f-S290h follow a similar pattern to steps S240-S260, but the difference is that steps S240-S260 are downward weaving, while S290f-S290h are upward weaving.

[0252] In the embodiments described above, the first V-shape formed by the first wire in each cycle can be an inverted V-shape with the opening facing downwards. That is, the first wire moves upwards from the last row of each S-cycle to the first row of the current S-cycle, wraps around the positioning pin, and then returns to the last row to form the shape. The first second V-shape of the first wire can also be an upright V-shape with the opening facing upwards. That is, the first wire moves downwards from the first row of each S-cycle to the last row of the current S-cycle, wraps around the positioning pin, and then returns to the first row to form the shape. The weaving pattern of the first wire is similar to that in this embodiment.

[0253] In this embodiment, the weaving pattern of the second wire is similar to that of the first wire in this embodiment, except that the number of intersections between each second V-shape and the first V-shape is different.

[0254] Reference Figure 27-30 The weaving of the second wire includes the following steps:

[0255] M410. Take each m+1 row as an M cycle, and make the second wire start to weave upwards from any weaving position of the cylindrical clamp in the m+y2 row that the first wire has not passed, as the second starting point of the M cycle. Move up and down in a second V-shape between the y2 row and the m+y2 row (the first row and the last row of the current M cycle).

[0256] Specifically, refer to Figure 27 Each two rows are considered an M-cycle (m=1). Starting from A4B3, the second wire moves towards A5B2, then moves downwards to A6B3, forming the first second V-shape, and then moves upwards to A7B2, forming the second second V-shape. The first and second second V-shapes are in opposite directions. This pattern continues until the wire reaches A10B3. At this point, neither the second nor the third row of braids is fully wound.

[0257] M420, if the second wire has not been fully wound into the y2th row of braids and the m+y2th row of braids, the second wire is moved down to the 2m+y2th row (i.e. the last row of the next M cycle) from any braid position different from the second starting point of the m+y2th row (the first row of the next M cycle) as the transition point of the current M cycle in a half second V shape.

[0258] Specifically, refer to Figure 27 If the second and third rows of braided sections are not fully wound, the second wire is moved down from A10B3 to A11B4. A10B3 may not have a positioning pin.

[0259] M430: Using the current position of the second wire in row 2m+y2 as the second starting point of the next M cycle, repeat steps M410 and M420 until the second wire is moved to row Y (i.e., the last row of the last M cycle).

[0260] Specifically, refer to Figure 28 The second wire starts moving upwards from A11B4 as the second starting point of the next M cycle to A12B3, then moves downwards from A12B3 as the inflection point to A13B4, and so on until it reaches A3B4. Then it moves downwards from A3B4 (A3B4 may not have a positioning pin) as the transition point to A4B5, and then moves upwards from A4B5 as the second starting point of the next M cycle to A5B4, and so on until it reaches A4B15.

[0261] M440, the second wire is moved up and down in a second V-shape between the Y-row and the Ym-row (i.e., the last row and the first row of the last M-cycle), so that the braiding positions of the Y-row and the Ym-row are fully wound.

[0262] Specifically, refer to Figure 29 The second wire starts from the second starting point A4B15 of the 15th row and continues to move upward to A5B14. Then, with A5B14 as the inflection point, it moves downward to A6B15. Following the above pattern, it moves until it reaches A3B14 (A3B14 does not need to be equipped with a positioning pin). At this time, the braided positions of the 15th and 14th rows are fully wound.

[0263] M450, move the second wire upwards from the transition point of the last M cycle in a half-second V-shape to the first row of the penultimate M cycle (i.e., the Y-2m row).

[0264] Specifically, refer to Figure 29 The second wire moves from the transition point A3B14 of the last M cycle to A4B13 on the first row of the second to last M cycle, and then moves down to A5B14 with A4B13 as the inflection point. This continues until it moves to the transition point A10B13 of the second to last M cycle (A10B13 does not need to be equipped with a positioning pin). At this time, the braided positions of the 13th and 14th rows are fully wound.

[0265] M460, repeat steps M440 and M450 to wind the second wire to the (m+y2)th row. If y2 equals 1, then execute M470; if y2 equals m+1, then execute M480; if y2 equals km+1 (k is a positive integer not equal to 1), then execute M490a-M490h.

[0266] In one embodiment, y2 equals 1, then the second wire is woven upwards, passing through the transition point of each M cycle until it wraps back to the second starting point of the m+1 row (i.e. the first M cycle). The second wire ends weaving and a second net is woven on the cylindrical clamp. There is no second reinforcing rib 210 on the second net.

[0267] The specific steps are as follows: M470, make the second wire bend and move up and down in a second V shape between the first row and the m+1th row, so that the braiding positions of the first row and the m+1th row are fully wrapped, and the second wire wraps back to the second starting point of the m+1th row to complete the braiding of the second wire.

[0268] Figure 27-30 In one embodiment shown, y2 equals m+1 (i.e., y2 = 2). After step M460, the second wire returns to the third row, so that the second wire crosses the transition point A10B3 of the third row and winds in a second V-shape between the third and second rows until the braiding position of the third and second rows is fully wound. The second wire winds to the transition point A3B2 of the second row, so that the second wire crosses the transition point A3B2 of the second row and winds in a second V-shape between the first and second rows until it winds back to the transition point A3B2 of the second row. Finally, it crosses the transition point A3B2 and moves to A4B3. The second wire ends the braiding and a second mesh is woven on the cylindrical clamp. There is no second reinforcing rib 210 on the second mesh.

[0269] The specific steps are as follows: M480, move the second wire between row y2 and row y2+m in a second V-shape, so that the braiding position of row y2+m is fully wrapped; move the second wire from the current position of row y2 as the transition point, and move it upward to row y2-m in a half-second V-shape; move the second wire between row y2 and row y2-m in a second V-shape, so that the braiding positions of row y2 and row y2-m are fully wrapped; move the second wire from the transition point of row y2 downward in a half-second V-shape back to the second starting point of row y2+m, completing the braiding of the second wire.

[0270] In one embodiment, y2 equals km+1 (k is a positive integer not equal to 1). That is, the second wire starts weaving from the second starting point of the starting M cycle (one of the weaving positions below the 2m+1th row) until it reaches the last M cycle, and then moves upwards to weave back to the 2m+1th row. At this point, there are still weaving positions greater than or equal to 2m+1th rows that have not been fully wound. According to the above pattern, the second wire also needs to move upwards from the m+1th row to weave. Before completing an M cycle, it moves to the upper row to wind the previous M cycle until it reaches the 1st row, and then moves downwards to weave until it returns to the second starting point of the starting cycle, thus completing the weaving of the second wire. A second mesh is woven on the cylindrical clamp, and there is no second reinforcing rib 210 on the second mesh.

[0271] The specific steps are as follows:

[0272] M490a, the second wire is moved up and down in a second V-shape between the y2th row and the y2+mth row, so that the braided position of the y2+mth row is fully wrapped.

[0273] M490b: Move the second wire from its current position in row y2 as the transition point of the previous M cycle, and move it upwards in a half-second V-shape to row y2-m (the first row of the previous M cycle).

[0274] M490c, the second wire is braided downwards with the current position of row y2-m as the second starting point of the previous M cycle, and moves up and down in a second V-shape between row y2-m and row y2.

[0275] M490d, if the second wire has not been fully wound in the y2-m row of braiding positions, the second wire is moved upward in a half-second V-shape to the y2-2m row (the first row of the next M-cycle) from any braiding position in the y2-m row that is different from its second starting point.

[0276] M490e: Using the current position of the second wire in row y2-2m as the second starting point of the next M-cycle, repeat steps M490c and M490d until the second wire is moved to row 1.

[0277] Steps M490c-M490e follow a similar pattern to steps M410-M430, but the difference is that M490c-M490e is an upward knitting pattern, while M410-M430 is a downward knitting pattern.

[0278] M490f causes the second wire to bend and move up and down in a second V-shape between the first row and the first+m row (first M cycle), so that the braiding positions of the first row and the first+m row are fully wound.

[0279] M490g, causing the second wire to move downwards from the transition point of the first M cycle in a half-second V-shape to the 2m+1 row (the last row of the second M cycle).

[0280] M490h, repeat steps M490f and M490g to make the second wire wrap back to the second starting point of the m+y2th row, thus completing the weaving of the second wire.

[0281] Steps M490f-M490h follow a similar pattern to steps M440-M460, but the difference is that M490f-M490h is an upward weaving, while M440-M460 is a downward weaving.

[0282] In the embodiments described above, the first second V-shape formed by the second wire in each cycle can be an inverted V-shape with the opening facing downwards. Alternatively, the first second V-shape formed by the second wire in each cycle can be an upright V-shape with the opening facing upwards; see reference... Figure 10-15 The second wire begins to be braided downwards from A9B2 (i.e., the first second V-shape is a positive V-shape), and its braiding pattern is similar to that of this embodiment.

[0283] Compared to the first embodiment, the bracket woven in the fourth embodiment has no reinforcing ribs in either the first or second mesh. The outer diameter of the bracket after compression is smaller, making it easier to assemble, more flexible, and the weaving process simpler. Similar to the third embodiment, the fourth embodiment can also be woven from any cycle.

[0284] Fifth Implementation Method

[0285] In the fifth embodiment, the weaving method of the first wire is the same as that in the fourth embodiment, and will not be described again here. After the first wire is woven, a first net is obtained, which does not have the first reinforcing rib 110.

[0286] Reference Figures 31-34The second wire is braided on the cylindrical clamp where the first wire has been braided. The braiding method of the second wire is the same as that in the first embodiment, and will not be described again here. After the second wire is braided, a second mesh is obtained, which has a second reinforcing rib 210. The braided wires of the second mesh and the braided wires of the first mesh are interwoven to form the required support.

[0287] Compared to the first embodiment, the bracket woven in the fifth embodiment has only one reinforcing rib, the outer diameter of the bracket after compression is smaller, it is easier to assemble, has better flexibility, and the weaving process is simpler.

[0288] Optionally, the braiding methods of the first wire and the second wire in the first to fifth embodiments described above can be combined to obtain more braiding methods for the support, which will not be elaborated here, but should be understood as being within the protection scope of this application.

[0289] Optionally, the weaving order of the first wire 10 and the second wire 20 can be interchanged. That is, the second wire 20 is woven first, so that the second wire 20 bends and moves up and down between the first row and the last row of the M cycle in a second V shape; then the first wire 10 bends and moves up and down between the first row and the last row of the S cycle in a first V shape.

[0290] Specifically, refer to Figure 36 The hook-and-loop structure is formed by two interlocking first V-shaped loops woven from the first thread 10 in opposite directions at the same weaving position; or by two interlocking second V-shaped loops woven from the second thread 20 in opposite directions at the same weaving position. The interlocking hook-and-loop structure can make the web more flexible and reduce its shrinkage rate.

[0291] Specifically, refer to Figure 37 The interlacing structure is formed by the interlacing of the first wire 10 with the second wire 20, the second wire 20 with the second wire 20, or the first wire 10 with the first wire 10. The spatial distribution of the interlacing follows the principle of uniformity and symmetry. The interlacing structure formed by the interlacing allows for good resilience after axial compression of the mesh, facilitates assembly, ensures uniform and tightness, and prevents obvious gaps, springing, or shifting after shaping.

[0292] One embodiment of this application also provides a stent, woven using the weaving method of any of the above embodiments. The stent is moved by bending and moving a first wire in a first V-shape around a positioning pin, and a second wire bending and moving in a second V-shape around the positioning pin where the first wire is not wrapped, resulting in a woven mesh with multiple diamond-shaped grids 30. These diamond-shaped grids 30 are arranged in multiple columns connected sequentially along the circumferential direction and in multiple rows connected sequentially along the axial direction. In some columns, one of the upper vertices 310 and lower vertices 320 is a hook-and-loop connection structure, and the other is an interlaced structure. That is, in some columns, two axially adjacent diamond-shaped grids 30 are connected by either a hook-and-loop structure or an interlaced structure. Therefore, the stent simultaneously possesses the advantages of easy assembly, low shrinkage rate, and good flexibility. This stent is suitable for use in curved cavities (such as the intestines), and its length is relatively fixed.

[0293] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0294] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0298] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
