Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
The main carrier 1 and the two branch carriers 2 which are connected with each other in the invention are carriers used for weaving the medical stent, corresponding pin columns can be inserted on the carriers according to the distribution requirement of weaving points, and the corresponding pin columns are used for winding silk threads.
As shown in fig. 1-3, a method for braiding transition regions of a Y-shaped support is provided, wherein the Y-shaped support adopts a main support 1 and two branch supports 2 with equal diameters, and N braiding points are uniformly divided on the projection of the main support 1 along the axial direction; the two branch carriers 2 evenly divide M weaving points along the respective axial projections; the yarn passes through the braiding point when it is wound to both ends of the main carrier 1 and the branch carrier 2.
The M weaving points of the two branch carriers 2 comprise L split weaving points 3 which are arranged continuously and H main weaving points 4 which are arranged continuously; the branch weaving point 3 is used for connecting two adjacent branch carriers 2, and the main weaving point 4 is used for connecting the branch carriers 2 and the main carrier 1, wherein M is smaller than N and smaller than 2*M; l+h+2=m; the number relation between M and N can ensure that the number of the weaving points of the main carrier 1 can be distributed to the main weaving points 4 (namely M is smaller than N) of each branch carrier 2, and redundant weaving points can be used as branch weaving points 3 (N is smaller than 2*M) on the branch carriers 2, wherein the numbers of the main weaving points 4 are the same as the numbers of adjacent weaving points on the main carrier 1 positioned on the same side, and the main carrier 1 and the two branch carriers 2 are connected with each other by the weaving points with different numbers in pairs, so that silk threads can be stacked in a crossed mode successively; when the yarn is transited from one branch to the other branch, the knitting direction is changed, so that the yarn can be stretched from the transition point to two different directions, and the yarn is tensioned.
The method comprises the following steps:
S1: from the bottom braiding point P1 of the main carrier 1 to the braiding point P2 of the top of the main carrier 1. The bottom end of the main carrier 1 refers to the end of the main carrier 1 away from the branch carrier 2.
S2: from the weaving point P2 to the weaving point P3 at the bottom end of one of the branch carriers 2. The bottom end of the branch carrier 2 is one end of the branch carrier 2 connected with the main carrier 1.
S3: and continuing winding the branch carrier 2 around the top end point of the branch carrier 2 to a weaving point position P4 at the bottom end of the branch carrier 2, executing the step S4 if the weaving point position P4 is a branch weaving point position 3, and executing the step S5 if the weaving point position P4 is a main weaving point position 4.
S4: the weaving point P4 is transferred to the weaving point 3 at the bottom end of the adjacent branch carrier 2, the step connects the weaving points of the main carrier 1 and the two branch carriers 2 in sequence, and then the branch carriers 2 are woven in the same way as the step S3. Then there are also two cases in step S3 at the bottom end of the branch carrier 2.
S5: from the weaving point P4 back to the weaving point P2 at the top end of the main carrier 1, the weaving is continued on the main carrier 1 spirally wound to the weaving point P5 at the bottom end of the main carrier 1 in the same manner as in step S1 until all the weaving point connections are completed.
Since the diameters of the two branch brackets are the same, the number of knitting points connected with the two branch brackets 2 on the main bracket 1 is preferably the same and symmetrically arranged, so that the bracket structure after knitting and forming is symmetrical and the surface is smoother. The branch braiding point 3 is preferably located in the region facing the two branch carriers 2, so that the thread can be connected to a nearer braiding point when transitioning between adjacent branches.
In order to ensure the ordering of the knitting appearance, the silk thread is knitted by adopting the same winding rule in the knitting process of the same support, wherein the winding rule comprises a winding mode and a winding period.
After the division of braiding point positions is completed and a designated winding rule is adopted to braid the transition region of the Y-shaped bracket, the braided bracket can be realized: each weaving point on the main carrier 1 is connected to two different weaving points of the branch carrier 2. Meanwhile, as the braiding point positions 3 connect adjacent branch carriers 2, every two of three branches can be connected.
Preferably, three branches of the Y-shaped bracket are all woven by adopting cross, and the principle of silk thread weaving of the transition area of the Y-shaped bracket is as follows: after the silk thread is woven to the weaving point in a clockwise or anticlockwise direction according to a certain weaving angle, the silk thread is transited to the adjacent weaving point of the adjacent branches in a clockwise or anticlockwise sequence, each weaving point is numbered before weaving, and the numbering rule is that the number of the main weaving point 4 is the same as that of the adjacent weaving point on the main carrier 1 positioned on the same side, and when the silk thread is woven, the main carrier 1 and the two branch carriers 2 are connected with each other in pairs through the weaving points with different numbers. The term counterclockwise or clockwise in the present invention refers to the view from the side of the braiding end point.
As can be seen from fig. 2, since the three basic shapes are all cylindrical, in order to prevent the situation that the knitting wires at the junction are too dense, L < H is set, and in a further design, the circumferential angle a occupied by the L division knitting points 3 is smaller than 80 °, as shown in fig. 3, the circumferential angle a refers to a circumferential angle formed by taking the centers of the two division knitting points 3 located at the outermost sides as a boundary.
The finished stent product formed by Corss braiding consists of grids formed by crossing wires, the side length angle of a single grid can be used for feeding back the overall performance of the stent to a great extent according to micro-element analysis, the diameters of a main carrier 1 and a branch carrier 2 are generally integers according to experience and bid product analysis, the braiding point position number of the main carrier 1 is equal to the diameter of the main carrier, the braiding point position of the branch carrier 2 can float in a small range, but the diamond shape with the side length of 2-2.5mm is required to be met, so that the requirements of radial force and bending performance are better met, and the three braiding angles are preferably selected to be 90-110 degrees according to the requirement of 50% of the stent shortening rate.
Since the diameter of the branch carrier 2 is in the range of 6-16mm, m=6-16, and L is equal to or less than 4 according to the setting requirement of the circumferential angle occupied by the L division weaving points 3, as shown in fig. 3.
According to the principle, the number and the weaving route of the support nodes with all specifications can be determined, for example, the diameter of a support is 20-16-16, the number of weaving points of the main support 1 is 20, the maximum selectable number of the weaving points of the branch support 2 is 14, the maximum selectable number of the branch weaving points 3 is 4, and the intermediate connection mode among three supports can be obtained by determining the number of the weaving points, so that a weaving chart can be output.
The transition region of the Y-shaped stent may be woven from one or more wires, each wire being woven from the bottom end of the main carrier 1 or the top end of the branch carrier 2.
The manner of braiding is described below in connection with two specific embodiments.
Example 1
As shown in fig. 2, the support with the weaving diameter of 22-16-16 is formed by dividing 22 weaving points on the main carrier 1, numbering the weaving points according to serial numbers 1-22 in sequence, dividing 14 weaving points on the two branch carriers 2 respectively, numbering the left branch carrier 2 according to serial numbers 1-14 in sequence, and numbering the right branch carrier 2 according to serial numbers 11-24 in sequence. The numbering principle of the braiding points is that the numbers of adjacent areas of the main branch and the branch are consistent as much as possible, and the braiding points with the same numbers are closer in distance, and when the silk threads are connected, different numbers between the adjacent branches are connected to form a cross grid.
For example, after the yarn is woven in a clockwise direction from the number 1 weaving end point at the bottom end of the main carrier 1 (clockwise when viewed from the bottom end of the main carrier 1) to the number 8 weaving end point at the top end of the main carrier 1, the yarn transitions to the number 9 weaving end point at the bottom end of the left branch carrier 2 in the clockwise direction, continues to weave clockwise along the left branch carrier 2 (clockwise when viewed from the bottom end of the left branch carrier 2), continues to weave downwards in the clockwise direction (clockwise when viewed from the top end of the left branch carrier 2) bypassing the uppermost end point of the left branch carrier 2, and two situations occur when weaving to the lowermost end point of the left branch carrier 2 as shown in fig. 2, and case one: the silk thread goes to the No. 7 knitting point position at the lowest end of the left branch carrier 2, then the silk thread is continuously transited to the No. 8 adjacent to the highest end of the main carrier 1 in the clockwise direction, and is continuously knitted back to the lowest end of the main carrier 1 along the main carrier 1 in the clockwise direction, so that one knitting cycle is completed. And a second case: the silk thread is moved to the 11 # weaving point position at the lowest end of the left side branch carrier 2, at this time, the silk thread should be transited to the 22 # weaving point position of the right side branch carrier 2 according to the anticlockwise angle, then the silk thread continues to weave on the right side branch carrier 2 according to the anticlockwise direction, and after the weaving of the right side branch carrier 2 is finished, the subsequent weaving can be performed according to the first or second condition. According to the method, each silk thread can be smoothly transited, and no obvious transition trace is formed at the junction.

It should be noted that after the clockwise or anticlockwise knitting direction of the wire is determined at the beginning of knitting, the knitting direction of the subsequent transition section and the branch section is also determined accordingly, so that the wires can be crossed, and the stability of the support structure is better. It should be noted that the number of nodes of the three branches is changed, the middle silk connection mode is different, but the general principle is not changed, namely, each output silk thread is connected with the nearest weaving point positions with different numbers on the other two branches, the scheme can obtain a smooth transition middle structure, and two of the three branches can be connected.
In summary, the following summary is provided:
the Y-shaped support is formed by weaving a main support and two branches, in order to ensure excessive smoothness of a transition section, wire transition is required to be ensured among three branches, generally, the diameter of the main support is larger than that of the branches, the number of weaving points of each branch is set to be consistent with the number of the diameters of each branch, the number of the weaving points of the main support is generally larger than that of the branches, and for stable connection of three branches, wire connection is required to be ensured for two-two of the three branches, namely, the connection is ensured by reasonable distribution of the three supporting point positions. The key lies in the connection mode of the middle transition section, the point position distribution rule adopted by the design is that two branches firstly need to provide half of the main fulcrum bit number to be connected with the main support, and the rest point positions are used for the two branches to be connected with each other. The connection principle of the wires among the branches is that different points among the two branches are sequentially connected in a clockwise or anticlockwise direction, so that the connection of transition sections is formed, and the braiding method of the wires on the branches is braiding according to a cross braiding method.
