Abstract

The invention discloses an atrial septal pore-forming scaffold and a conveyor thereof. The scaffold is in continuous netted structure; the width of a section rod of a main unit section which is positioned in the middle is larger than that of section rods of secondary unit sections which are positioned on both sides of the scaffold so that deformation resistance of the secondary unit sections on both sides of the scaffold is less; after the scaffold is implanted, both sides of the scaffold are first expanded to form a trumpet shape, and the main unit section in the middle is then expanded to form a column shape, thus the scaffold forms the structure with the column shape in middle and the trumpet shape on both sides. Because a certain effect of 'dog bone' is generated in the process of scaffold expansion, i.e. a process of axial retraction is generated after scaffold expansion, the trumpet shape formed on both sides is just fastened outside a formed pore after retracting slightly when the atrial septal pore-forming scaffold is expanded, and thus the scaffold is accurately positioned, can be firmly fixed in the formed hole and are not easy to fall off to both sides.

具体实施方式 Detailed ways

[0025] 以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所做的任何修改、等同替换、改进等,均应包含在本发明保护的范围之内。 [0025] The foregoing is only preferred embodiments of the present invention but are not intended to limit the present invention, all within the spirit and principle of the present invention, any changes made, equivalent substitutions and improvements should be included within the scope of protection of the present invention.

[0026] 本发明中的房间隔造孔支架,包括: [0026] In the present invention, atrial septal pore bracket, comprising:

[0027] 沿轴向分别位于支架两侧的副单元节,其柱面由首尾相连呈波浪状排列的若干节杆沿排列方向环绕构成。 [0027] sub-units are located at the axial side of the bracket along the section, which is joined end to end by a cylinder arrangement direction of a plurality of segmented rods arranged around wavy configuration.

[0028] 沿轴向位于支架中部的主单元节,其柱面由首尾相连呈波浪状排列的若干节杆沿排列方向环绕构成。 [0028] The main unit bracket located in the middle section in the axial direction, which is joined end to end by a cylinder arrangement direction of a plurality of segmented rods arranged around wavy configuration. 上述主单元节的节杆宽度大于上述副单元节的节杆宽度。 It means the width of the main rod section larger than the section of the sub-units segmented rod section width.

[0029] 连接杆,连接相邻的上述主单元节和上述副单元节。 [0029] The connecting rod connecting adjacent sections of the main unit and the sub unit section.

[0030] 由此可见,上述主单元节、副单元节和连接杆使本发明中的房间隔造孔支架具有连续型网状结构,由于位于中部的主单元节的节杆宽度大于位于两侧的副单元节的节杆宽度,使得支架两侧副单元节的变形抗力较小,所以在植入后,支架两侧将先扩张形成喇叭形的形状,而中部主单元节后扩张形成柱状的形状。 [0030] Thus, the main unit section, and the sub-unit sections in the connecting rod of the present invention that the atrial septal pore support has continuous network structure, since the width of the main section of the rod unit is greater than the central section on both sides segmented rod section width of the sub-units, such sub-units on both sides of the deformation resistance smaller section of the stent, so that after implantation, both the first expandable stent flared shape, while the central main unit postganglionic expansion of a columnar shape. 这样支架呈现中间柱状、两侧喇叭形的结构。 Such intermediate bracket exhibits a columnar structure, both sides of the horn. 由于支架扩张过程中均存在一定的“狗骨头”效应,即支架在扩张后有一个轴向回缩的过程,使得本发明中房间隔造孔支架扩张时,两侧形成的喇叭形稍回缩后正好卡在造孔的外侧,由此准确定位,且能牢固的固定在造孔部位,不易向两边脱落。 Since the expansion of the stent both during certain "dog bone" effect, i.e. the stent after the expansion process with an axial retraction, the present invention is such that atrial septal pore expansion of the stent, formed on both sides of horn retracted slightly after just stuck on the outside of the pore, thereby accurately positioning, and can be securely fixed in the pore portion, not falling to the sides. 进一步,本发明中的房间隔造孔支架,由于其结构上的特点,使得只需进行一次扩张就可以准确而牢固的植入造孔部位,相对于现有技术先进行一次扩张将支架植入造孔、再对支架两端各进行一次扩张以防止脱落,使用本发明中的房间隔造孔支架,大大减小了手术难度,并缩短了手术时间。 Further, in the present invention atrial septal pore stent, because of its structural features, such that only once expanded can accurately implant and solid pore portion, with respect to the prior art for a stent expandable to pore, and then both ends of each of the stent once expanded to prevent falling, the present invention is used in atrial septal pore bracket, greatly reduces the difficulty of operation, and to shorten the operation time.

[0031] 下面介绍本发明房间隔造孔支架的两个实施例。 [0031] The present invention is described below room pore spacing two embodiments of the stent.

[0032] 实施例一 [0032] Example a

[0033] 图1为本发明第一种房间隔造孔支架的结构示意图,图2为图1所示支架扩张后的结构示意图。 [0033] Figure 1 is a schematic structural diagram of a first housing spacer bracket pore invention, FIG 2 is a schematic configuration shown in FIG. 1 after the stent is expanded. 图1和图2所示的支架10包括:一个柱状的主单元节1、两个柱状的副单元节2和连接杆3。 1 and holder 2 shown in FIG. 10 comprises: a cylindrical main unit section 1, section two cylindrical sub-unit 2 and the connecting rod 3. [0034] 两个柱状的副单元节2沿轴向分别位于支架10的两侧,首尾相连呈波浪状排列的若干节杆21,沿排列方向环绕构成每个副单元节2的柱面。 [0034] two sub-units of the column section 2 in the axial direction on each side of the bracket 10, a plurality of end to end section 21 of the rod wavy arranged around the cylindrical section constituting each sub-unit 2 along the arrangement direction. 每个副单元节2的柱面波浪状的波宽和波高均相同。 Each sub-section of the cylindrical section 2 wavy wave height and the wave width are the same. 在其他应用场合,每个副单元节2的柱面波浪状的波宽和波高也可以不全相同。 In other applications, each of the sub-section of the cylindrical section 2 of the corrugated wave height and the wave width of the same may be incomplete.

[0035] 一个柱状的主单元节1沿轴向位于支架10的中部,首尾相连呈波浪状排列的若干节杆11,沿排列方向环绕构成主单元节1的柱面。 [0035] a cylindrical main unit 1 in the axial direction in the central section of the stent 10, both linked to a plurality of segmented rods 11 arranged in wavy, arrangement direction around the main unit 1 composed of a cylindrical section. 主单元节1的节杆11的宽度大于副单元节2的节杆21的宽度,这样使得副单元节2所在的两侧抗力较小,在扩张时可以先扩张呈喇叭形。 Section of the main unit section 11 is greater than the width of a sub-unit section of the width of the section 2 of the rod 21, so that both smaller resistance section 2 where the sub-unit, expanded upon expansion can first flared.

[0036] 本实施例中的主单元节1和副单元节2的柱面均为近似正弦波的形状,在其他应用场合,该柱面还可设计为其他类型。 Cylindrical [0036] section of the present embodiment the main unit 1 and the sub-unit sections in Embodiment 2 are approximate sine wave shape, in other applications, the cylinder can also be designed for other types.

[0037] 连接杆3连接相邻的主单元节1和副单元节2。 [0037] The connecting rod 3 is connected to the adjacent section of the main unit 1 and the sub unit 2 sections. 相邻主单元节1和副单元节2的柱面相对一侧的每对波峰和波谷之间均连接有一个连接杆3,为全闭环结构,由此保证支架10有足够的支撑强度,进一步增强牢固性。 It is connected to a connecting rod 3 between each pair of crests and valleys of the main unit 1 and the sub unit section cylindrical section 2 opposite the side adjacent to closed loop structure, thereby ensuring that the stent 10 has sufficient strength to support further enhanced robustness. 连接杆3的宽度小于等于主单元节1的节杆11 的宽度,以增加支架的柔顺性。 The width of the connecting rod 3 is greater than the width of the rod section 111 of the main unit section, in order to increase the flexibility of the stent. 当然,相邻主单元节1和相邻副单元节2的柱面相对一侧, 也可以每间隔若干对波峰和波谷才连接有一个连接杆3。 Of course, the adjacent sections of the main unit and the sub unit section adjacent the opposite side of a cylinder 2, may be a number of intervals of the peaks and troughs are connected to only one connecting rod 3.

[0038] 连接杆3为S型,这样可以为各单元节之间的位置变化起到适当的缓冲。 [0038] S-type connecting rod 3, which can play an appropriate buffer for the change in position between the respective unit sections. 连接杆3和连接杆3'还可以设计为其他弯曲型,例如U型、V型和N型等。 Connecting rod connecting rod 3 and 3 'can also be designed for other curved profile, eg U-shaped, V-type and N-type and the like. 连接杆3的宽度对支架10的结构并不具有决定性的影响,在柔顺性要求不高时,连接杆3的宽度可以大于节杆11 的宽度。 The width of the connecting rod 3 does not have a decisive influence on the structure of stent 10, while less demanding compliance, the width of the connecting rod 3 may be greater than the width 11 of the section bar.

[0039] 为防止在支架扩张过程中出现的失稳问题,主单元节1的节杆11的宽度小于等于自身的厚度,副单元节2的节杆21的宽度小于等于自身的厚度,连接杆3的宽度小于等于自身的厚度。 [0039] In order to prevent instability problems in the process of expansion of the stent, the width of the section of rod section 11 of the main unit 1 is equal to its thickness less than the width 21 of the sub-lever unit section, Section 2 is itself less than or equal thickness, the connecting rod 3 is equal to a width smaller than their thickness. 上述宽度均指垂直于弯曲平面方向上的宽度,厚度均指平行于弯曲平面方向上的厚度。 Refer to the above-described width perpendicular to the bending width, thickness refers to the plane parallel to the direction of thickness of the bent both in the plane direction.

[0040] 本实施例中的支架可以由医用不锈钢管或钴基合金材料或其他材料管材经激光雕刻而成。 [0040] This embodiment can be implemented in the stent tube is made of medical stainless steel or cobalt-based alloy or other material from the pipe by laser engraving.
