技术领域technical field
本发明涉及医疗器械技术领域，特别涉及一种带线锚钉和带线锚钉系统。The invention relates to the technical field of medical instruments, in particular to a threaded anchor and a threaded anchor system.
背景技术Background technique
关节周围肌腱、韧带损伤是骨科常见的伤病，临床上常用带线锚钉将损伤的肌腱残端固定到骨组织，以恢复肌腱的正常结构和关节功能，通过腱骨愈合达到最终固定的目的。Periarticular tendon and ligament injuries are common injuries in orthopedics. In clinical practice, anchors with wires are commonly used to fix the injured tendon stump to bone tissue, so as to restore the normal structure of the tendon and joint function, and achieve the final fixation through tendon-bone healing.
腱骨愈合的过程需要肌腱与骨端的粗糙面有一定的接触面积并有牢固的接触稳定性。因此，带线锚钉在骨内的固定强度，是手术成功的关键和基础。The process of tendon-bone healing requires a certain contact area and firm contact stability between the tendon and the rough surface of the bone end. Therefore, the fixation strength of the wire anchor in the bone is the key and basis for the success of the operation.
目前现有的带线锚钉多数是在锚钉主体上设置螺纹结构，通过预钻一个直径略小于锚钉主体的通道，再将锚钉主体旋转拧入或直接打入骨内，达到固定的目的。然而通过螺纹与骨组织产生的加压稳定性有限。临床上带线锚钉在植入后出现锚钉主体松动、拨出，导致固定失效、手术失败的现象常有发生，特别在骨量减少或骨质疏松的病例，以及在关节活动范围大、肌腱力量强大肩肘等关节部位更容易发生。At present, most of the existing threaded anchors are provided with a threaded structure on the main body of the anchor, and a channel with a diameter slightly smaller than the main body of the anchor is pre-drilled, and then the main body of the anchor is screwed or directly driven into the bone to achieve the purpose of fixation. However, the compression stability produced by the threads and the bone tissue is limited. Clinically, the main body of the threaded anchor is loosened and pulled out after implantation, leading to fixation failure and surgical failure, especially in cases of osteopenia or osteoporosis, and it is more likely to occur in joints such as the shoulder and elbow with a large range of joint motion and strong tendon strength.

综上所述，在本发明提供的带线锚钉和带线锚钉系统中，所述带线锚钉包括球囊锚定组件；所述球囊锚定组件包括嵌入部和具有自膨性的球囊本体；所述球囊本体被置于输送管内时，受到所述输送管的限制而处于收缩状态；所述球囊本体从所述输送管中脱出并植入预定对象时，所述球囊本体基于自膨性向外扩张而由所述收缩状态转换至扩张状态，以锚定于所述预定对象中；其中，所述球囊本体包括多个网格孔；所述球囊本体处于所述扩张状态时，所述嵌入部用于嵌入所述预定对象，并且所述网格孔允许所述预定对象进入。To sum up, in the wire anchor and the wire anchor system provided by the present invention, the wire anchor includes a balloon anchoring assembly; the balloon anchoring assembly includes an embedded part and a self-expandable balloon body; when the balloon body is placed in the delivery tube, it is in a contracted state due to the restriction of the delivery tube; when the balloon body is released from the delivery tube and implanted into a predetermined object, the balloon body expands outward based on self-expandability and switches from the contracted state to an expanded state to anchor in the predetermined object; Wherein, the balloon body includes a plurality of mesh holes; when the balloon body is in the expanded state, the embedding portion is used to embed the predetermined object, and the mesh holes allow the predetermined object to enter.
如此配置，在球囊本体从输送管中脱出并植入预定对象(如患者的骨质)时，基于球囊本体的自膨性，其能够从收缩状态转换至扩张状态，从而锚定于预定对象中。并且在该过程中，球囊本体能够根据患者的骨质情况进行自适应调节；基于球囊本体的自膨性，若患者的骨质较硬，则球囊本体的扩张幅度较小，若患者的骨质较疏松，则球囊本体的扩张幅度较大，从而能可靠而稳固地固定在患者的骨质中，满足不同患者的临床需求。此外，带线锚钉的植入过程快速简便，只需将球囊本体从输送管中推出并插入患者的骨质，无需如螺纹固定的方式进行旋拧，而是即刻产生自膨胀，完成固定。进一步的，嵌入部能够嵌入骨质，进一步提高与骨质的连接强度和可靠性，而网格孔允许骨质进入，有利于骨质向内生长融合。So configured, when the balloon body is dislodged from the delivery tube and implanted into a predetermined object (such as a patient's bone), based on the self-expandability of the balloon body, it can switch from a contracted state to an expanded state, thereby being anchored in the predetermined object. And in this process, the balloon body can be adaptively adjusted according to the patient's bone quality; based on the self-expandability of the balloon body, if the patient's bone quality is relatively hard, the expansion range of the balloon body will be small, and if the patient's bone quality is relatively loose, the expansion range of the balloon body will be relatively large, so that it can be reliably and firmly fixed in the patient's bone quality, meeting the clinical needs of different patients. In addition, the implantation process of the anchor with wire is quick and easy. It only needs to push the balloon body out of the delivery tube and insert it into the patient's bone. It does not need to be screwed in the way of screw fixation, but it will immediately self-expand and complete the fixation. Furthermore, the embedding part can be embedded in the bone, further improving the strength and reliability of the connection with the bone, and the grid holes allow the bone to enter, which is beneficial to the in-growth and fusion of the bone.

本发明的目的在于提供一种带线锚钉和带线锚钉系统，以解决现有的带线锚钉易产生松动、拨出的问题。以下参考附图进行描述。The object of the present invention is to provide a wire anchor and a wire anchor system to solve the problem that the existing wire anchor is easy to loosen and pull out. Description is made below with reference to the accompanying drawings.
请参考图1至图12，本发明实施例提供一种带线锚钉1，其包括球囊锚定组件10；所述球囊锚定组件10包括嵌入部120和具有自膨性的球囊本体110；所述球囊本体110被置于输送管21内时，受到所述输送管21的限制而处于收缩状态(如图1和图2所示)；所述球囊本体110从所述输送管21中脱出并植入预定对象时，所述球囊本体110基于自膨性向外扩张而由所述收缩状态转换至扩张状态，以锚定于所述预定对象中(请参考图5所示)；其中，所述球囊本体110包括多个网格孔112，所述球囊本体110处于所述扩张状态时，所述嵌入部120用于嵌入所述预定对象，并且所述网格孔112允许所述预定对象进入。需要说明的，所述网格孔112允许预定对象进入可以理解为球囊本体110相对于预定对象产生扩张和挤压后，预定对象的一部分直接被挤压进入网格孔112，也可以理解为预定对象在球囊本体110植入手术之后，产生增生而生长进入网格孔112。Please refer to FIGS. 1 to 12 , the embodiment of the present invention provides a wire anchor 1 , which includes a balloon anchoring assembly 10; the balloon anchoring assembly 10 includes an embedded portion 120 and a self-expanding balloon body 110; 10 is converted from the contracted state to the expanded state based on self-expanding outward expansion, so as to be anchored in the predetermined object (please refer to FIG. 5 ); wherein, the balloon body 110 includes a plurality of mesh holes 112, and when the balloon body 110 is in the expanded state, the embedded part 120 is used to embed the predetermined object, and the mesh holes 112 allow the predetermined object to enter. It should be noted that the mesh hole 112 allows the predetermined object to enter. It can be understood that after the balloon body 110 is expanded and squeezed relative to the predetermined object, a part of the predetermined object is directly squeezed into the mesh hole 112.
基于如上所述的带线锚钉1，本发明实施例还提供一种带线锚钉系统，其包括如上所述的带线锚钉1和操作工具2。所述操作工具2包括沿自身轴向设置的输送管21以及可活动地穿设于所述输送管21中的推送件22；所述输送管21用于装载带线锚钉1的球囊本体110，所述推送件22用于驱动所述球囊本体110从所述输送管21中脱出并植入预定对象。Based on the anchor with wire 1 described above, an embodiment of the present invention further provides an anchor with wire system, which includes the anchor with wire 1 and the operating tool 2 as described above. The operating tool 2 includes a delivery tube 21 arranged in its axial direction and a pusher 22 movably threaded through the delivery tube 21; the delivery tube 21 is used to load the balloon body 110 of the anchor with wire 1, and the pusher 22 is used to drive the balloon body 110 to escape from the delivery tube 21 and implant it into a predetermined object.
为便于叙述，下面以患者的骨质作为预定对象的手术应用场景进行说明，需要说明的，在其它的例如模拟或训练的应用场景中，也可以将骨假体模型作为预定对象，本领域技术人员可相应地进行代换理解，而不应将预定对象仅仅理解为患者的骨质。For the convenience of description, the operation application scenario in which the patient's bone quality is used as the predetermined object will be described below. It should be noted that in other application scenarios such as simulation or training, the bone prosthesis model can also be used as the predetermined object, and those skilled in the art can understand it accordingly, and should not only understand the predetermined object as the patient's bone quality.
请参考图1、图2和图4，在一个可替代的示范例中，所述操作工具2还包括手柄23和推钮24，手柄23具有沿轴向贯通的内孔230，输送管21的近端(图2的右端)与手柄23固定连接，输送管21的内腔与内孔230保持贯通。推送件22沿输送管21的轴向可活动地穿设于输送管21的内腔和内孔230中。手柄23具有与内孔230连通的侧孔231，推钮24沿手柄23的轴向可移动地设置于侧孔231中，并且推钮24与推送件22连接，如此手柄23在被推动时，将会带动推送件22沿输送管21的轴向移动。Please refer to Fig. 1, Fig. 2 and Fig. 4, in an alternative example, the operating tool 2 further includes a handle 23 and a push button 24, the handle 23 has an inner hole 230 penetrating in the axial direction, the proximal end (the right end of Fig. 2 ) of the delivery tube 21 is fixedly connected to the handle 23, and the inner cavity of the delivery tube 21 is kept connected with the inner hole 230. The pushing member 22 is movably installed in the inner cavity and the inner hole 230 of the delivery tube 21 along the axial direction of the delivery tube 21 . The handle 23 has a side hole 231 communicating with the inner hole 230, and the push button 24 is movably arranged in the side hole 231 along the axial direction of the handle 23, and the push button 24 is connected with the push piece 22, so that when the handle 23 is pushed, it will drive the push piece 22 to move along the axial direction of the delivery pipe 21.
进一步的，球囊本体110被压缩后，能够转换至收缩状态而被装载于输送管21中，如图2和图3所示。球囊本体110优选被装载于输送管21的远端(图2的左端)靠近管口处。进而推送件22在向远端移动时，能够驱动球囊本体110从输送管21中脱出。使用中，可先在患者的骨质上钻孔，而后将载有球囊本体110的输送管21的远端伸入骨质上所钻的孔中，推动推钮24并通过推送件22驱动球囊本体110自输送管21中脱出，此时球囊本体110不再受到输送管21的约束，基于其自膨性而转换至扩张状态，从而能够嵌入骨质。可选的，输送管21上设置有刻度线，以便于识别输送管21插入骨质的深度。Further, after the balloon body 110 is compressed, it can be converted into a contracted state and loaded into the delivery tube 21 , as shown in FIGS. 2 and 3 . The balloon body 110 is preferably loaded at the distal end (the left end in FIG. 2 ) of the delivery tube 21 near the mouth of the tube. Furthermore, when the pushing member 22 moves to the distal end, it can drive the balloon body 110 to escape from the delivery tube 21 . In use, a hole can be drilled in the patient's bone first, and then the distal end of the delivery tube 21 carrying the balloon body 110 is inserted into the drilled hole in the bone, and the push button 24 is pushed to drive the balloon body 110 out of the delivery tube 21 through the pusher 22. At this time, the balloon body 110 is no longer constrained by the delivery tube 21, and is converted to an expanded state based on its self-expandability, so that it can be embedded in the bone. Optionally, a scale line is provided on the delivery tube 21, so as to identify the depth at which the delivery tube 21 is inserted into the bone.
更进一步的，带线锚钉1还包括缝线13，缝线13与球囊锚定组件10连接。可选的，推送件22具有沿轴向的贯通孔，其用于供缝线13穿设。这样在完成将球囊本体110植入骨质上所钻的孔中后，操作工具2可向近端退出，此时缝线13和球囊锚定组件10即被留置在骨质上。Furthermore, the threaded anchor 1 further includes sutures 13 connected to the balloon anchoring assembly 10 . Optionally, the pushing member 22 has a through hole along the axial direction, which is used for the suture 13 to pass through. In this way, after the balloon body 110 is implanted into the drilled hole on the bone, the operating tool 2 can be withdrawn proximally, and at this time, the suture 13 and the balloon anchoring assembly 10 are left on the bone.
基于上述配置，在球囊本体110从输送管中脱出并植入预定对象(如患者的骨质)时，基于球囊本体110的自膨性，其能够从收缩状态转换至扩张状态，从而锚定于预定对象中。并且在该过程中，球囊本体110能够根据患者的骨质情况进行自适应调节；基于球囊本体110的自膨性，若患者的骨质较硬，则球囊锚定组件的扩张幅度较小，若患者的骨质较疏松，则球囊本体110的扩张幅度较大，从而能可靠而稳固地固定在患者的骨质中，满足不同患者的临床需求。此外，带线锚钉1的植入过程快速简便，只需将球囊本体110从输送管21中推出并插入患者的骨质，无需如螺纹固定的方式进行旋拧，而是即刻产生自膨胀，完成固定。进一步的，嵌入部120能够嵌入骨质，进一步提高与骨质的连接强度和可靠性，而网格孔112允许骨质进入，有利于骨质向内生长融合。Based on the above configuration, when the balloon body 110 is released from the delivery tube and implanted into a predetermined object (such as a patient's bone), based on the self-expandability of the balloon body 110, it can be converted from a contracted state to an expanded state, thereby being anchored in the predetermined object. And in this process, the balloon body 110 can be adaptively adjusted according to the patient's bone quality; based on the self-expandability of the balloon body 110, if the patient's bone quality is relatively hard, the expansion range of the balloon anchor assembly will be small; if the patient's bone quality is relatively loose, the expansion range of the balloon body 110 will be relatively large, so that it can be reliably and firmly fixed in the patient's bone quality, meeting the clinical needs of different patients. In addition, the implantation process of the threaded anchor 1 is quick and easy. It only needs to push the balloon body 110 out of the delivery tube 21 and insert it into the patient's bone. It does not need to be screwed in the way of threaded fixation, but self-expands immediately to complete the fixation. Furthermore, the embedding part 120 can be embedded in the bone, further improving the connection strength and reliability with the bone, and the grid holes 112 allow the bone to enter, which is beneficial to the in-growth and fusion of the bone.
需要说明的，收缩状态和扩张状态是指球囊本体110的一组相对的状态，应理解，球囊本体110处于收缩状态时，其径向外尺寸(指球囊本体110的横截面的最小外包络圆的直径)小于处于扩张状态时的径向外尺寸。但收缩状态和扩张状态并非限定球囊本体110的具体尺寸。具体的，球囊本体110处于收缩状态时，受到输送管21的约束。因此其处于收缩状态时的径向外尺寸是适配于不同的输送管21内径而并不是固定的。球囊本体110处于收缩状态时的径向外尺寸优选为2mm～20mm。It should be noted that the contracted state and the expanded state refer to a set of relative states of the balloon body 110. It should be understood that when the balloon body 110 is in the contracted state, its radially outer dimension (referring to the diameter of the smallest outer enveloping circle of the cross section of the balloon body 110) is smaller than the radially outer dimension when it is in the expanded state. However, the contracted state and the expanded state do not limit the specific size of the balloon body 110 . Specifically, when the balloon body 110 is in a deflated state, it is constrained by the delivery tube 21 . Therefore, its radial outer dimension in the contracted state is adapted to different inner diameters of the delivery tube 21 and is not fixed. The radial outer dimension of the balloon body 110 in the contracted state is preferably 2 mm to 20 mm.
同样的，球囊本体110处于扩张状态时，受到骨质的约束，由于不同患者的骨质情况不同，因此实际上球囊本体110在被植入骨质后，其扩张状态的径向外尺寸并不相同，甚至球囊本体110处于扩张状态时的周向外轮廓形态也不一定相同。球囊本体110处于扩张状态时的径向外尺寸优选为3mm～40mm。优选的，球囊本体110在未受外力时处于最大扩张状态，进而可通过外力对其进行压缩，使其转换至收缩状态或小于收缩状态的形态，从而可以被装载于输送管21中。Similarly, when the balloon body 110 is in the expanded state, it is constrained by the bone quality. Since the bone quality of different patients is different, in fact, after the balloon body 110 is implanted in the bone, the radial outer dimensions of the expanded state are not the same, and even the circumferential outer contour shape of the balloon body 110 is not necessarily the same when the balloon body 110 is in the expanded state. The radial outer dimension of the balloon body 110 in the expanded state is preferably 3 mm to 40 mm. Preferably, the balloon body 110 is in a state of maximum expansion when no external force is applied, and then can be compressed by an external force to switch to a contracted state or a shape smaller than the contracted state, so that it can be loaded into the delivery tube 21 .
请参考图3和图6，其示范性地示出了带线锚钉1的一个优选示例，其中图3中球囊本体110处于收缩状态，图6中球囊本体110处于最大扩张状态。在一个可替代的示范例中，输送管21的内腔为圆柱形，适配的，球囊本体110处于收缩状态时，大致呈圆柱形。可选的，球囊本体110的远端闭合，并优选呈圆滑地形状，以避免对骨质产生不期望的伤害。而在球囊本体110处于最大扩张状态时，大致呈球形，如图6所示。可以理解，球囊本体110在被植入骨质中并扩张时，并不一定能扩张至如图6所示的最大扩张状态，而可能是处于图3所示的收缩状态和图6所示的最大扩张状态之间的某一状态(亦即扩张状态)。Please refer to FIG. 3 and FIG. 6 , which exemplarily show a preferred example of the anchor with wire 1 , wherein in FIG. 3 the balloon body 110 is in a deflated state, and in FIG. 6 the balloon body 110 is in a maximally expanded state. In an alternative example, the lumen of the delivery tube 21 is cylindrical, and when adapted, the balloon body 110 is substantially cylindrical when it is in a deflated state. Optionally, the distal end of the balloon body 110 is closed, and is preferably in a smooth shape, so as to avoid undesired damage to the bone. When the balloon body 110 is in the maximum expansion state, it is roughly spherical, as shown in FIG. 6 . It can be understood that when the balloon body 110 is implanted into the bone and expands, it does not necessarily expand to the maximum expansion state shown in FIG. 6 , but may be in a certain state (that is, an expansion state) between the contracted state shown in FIG.
进一步，所述多个网格孔112由多个网格杆111相互交叉连接形成，和/或，所述多个网格孔112通过镂空球囊本体110而形成。一些实施例中，球囊本体110包括多个网格杆111，多个网格杆111相互交叉连接形成网格孔112，使得球囊本体110具有良好的弹性，便于收缩及弹开。另一些实施例中，网格孔112也可以通过镂空球囊本体110而形成。球囊本体110采用不锈钢、钛合金、高分子材料、可吸收材料或镍钛合金材质制成，其可通过对棱柱状、球状、囊状或椭球状等形状的基材进行切割等方式成型。可选的，在所述球囊本体110处于所述扩张状态时，所述网格孔112呈菱形、平行四边形、矩形、圆形和椭圆形中的至少一者。如图6所示，在一个示范例中，大部分的网格孔112呈菱形，少量的网格孔112可以呈平行四边形或矩形。Further, the plurality of grid holes 112 are formed by cross-connecting the plurality of grid rods 111 , and/or, the plurality of grid holes 112 are formed by hollowing out the balloon body 110 . In some embodiments, the balloon body 110 includes a plurality of grid rods 111 , and the plurality of grid rods 111 are cross-connected to form grid holes 112 , so that the balloon body 110 has good elasticity and is easy to contract and pop open. In some other embodiments, the mesh holes 112 can also be formed by hollowing out the balloon body 110 . The balloon body 110 is made of stainless steel, titanium alloy, polymer material, absorbable material or nickel-titanium alloy, and can be formed by cutting a prismatic, spherical, sac-shaped or ellipsoid-shaped base material. Optionally, when the balloon body 110 is in the expanded state, the grid holes 112 are in at least one of a rhombus, a parallelogram, a rectangle, a circle and an ellipse. As shown in FIG. 6 , in one example, most of the mesh holes 112 are rhombus-shaped, and a small number of mesh holes 112 may be parallelogram-shaped or rectangular-shaped.
可选的，所述嵌入部120包括设置于所述网格杆111上和/或所述网格孔112的邻接部位上的棱边、棱角和锥角中的至少一者。这里网格孔112的邻接部位指相邻网格孔112的公共边或公共角等相邻部位。Optionally, the embedding portion 120 includes at least one of edges, corners and taper angles disposed on the grid rods 111 and/or adjacent to the grid holes 112 . Here, the adjacent parts of the mesh holes 112 refer to adjacent parts such as common sides or common corners of adjacent mesh holes 112 .
如图6所示，在第一个优选示例中，嵌入部120包括设置在网格杆111上的棱边，棱边亦即网格杆111朝向外侧的表面与朝向网格孔112的侧面的交接边，其较为锋锐，在球囊本体110扩张时，这些锋锐的棱边可以切入骨质，增大球囊本体110的扩张形变量。相应的，部分骨质会进入网格孔112的范围内，有利于骨质向内生长融合。可以理解的，一些实施例中，嵌入部120实际上可以由网格杆111的边缘直接构成，即嵌入部120并不需要额外设置，而直接将网格杆111的边缘配置为嵌入部120。这样的情况，也可以认为嵌入部120与网格杆111一体成型。另一些实施例中，嵌入部120可以额外地设置于网格杆111上，其连接形式不限。例如可以是熔接或粘接。As shown in FIG. 6 , in the first preferred example, the embedding portion 120 includes edges disposed on the grid rods 111 . The edges, that is, the junction edges between the outer surface of the grid rods 111 and the side faces toward the grid holes 112 , are relatively sharp. When the balloon body 110 expands, these sharp edges can cut into the bone, increasing the expansion deformation of the balloon body 110 . Correspondingly, part of the bone will enter the range of the mesh holes 112, which is beneficial to the ingrowth and fusion of the bone. It can be understood that in some embodiments, the embedded part 120 can actually be formed directly by the edge of the grid rod 111 , that is, the embedded part 120 does not need to be additionally provided, and the edge of the grid rod 111 is directly configured as the embedded part 120 . In such a case, it can also be considered that the embedded part 120 is integrally formed with the grid rod 111 . In other embodiments, the embedded part 120 may be additionally disposed on the grid rod 111 , and the connection form is not limited. For example welding or adhesive bonding is possible.
如图7和图8所示，在第二个优选示例中，嵌入部120包括设置在网格杆111和/或网格孔112的邻接部位上的棱角。棱角可以是尖锐的锐角，也可以是钝角或直角，其形态不限。棱角可以均匀分布，也可以集中在球囊本体110的中间部位，本实施例对此不限。棱角的设置，使得球囊本体110在扩张时可以更轻松地刺入骨质，并且棱角可以增大球囊本体110与骨质的摩擦力，提高球囊本体110的固定效果。As shown in FIG. 7 and FIG. 8 , in the second preferred example, the embedding portion 120 includes corners disposed on adjacent portions of the grid rods 111 and/or the grid holes 112 . Angles can be sharp acute angles, obtuse angles or right angles, and the shape is not limited. The edges and corners can be evenly distributed, or concentrated in the middle of the balloon body 110, which is not limited in this embodiment. The setting of the corners allows the balloon body 110 to penetrate into the bone more easily when expanding, and the corners can increase the friction between the balloon body 110 and the bone, improving the fixation effect of the balloon body 110 .
如图9所示，在第三个优选示例中，嵌入部120包括设置在网格孔112的邻接部位上的锥角。锥角如同尖刺状向外延伸，在球囊本体110扩张时，锥角可以更轻松地刺入骨质，并且锥角可以增大球囊本体110与骨质的摩擦力，提高球囊本体110的固定效果。同样的，棱角、锥角等结构，可以额外地设置于网格杆111或网格孔112的邻接部位上，也可以与网格杆111或网格孔112的邻接部位一体成型，本实施例对此不限。As shown in FIG. 9 , in the third preferred example, the embedding portion 120 includes a taper angle provided on the adjacent portion of the grid hole 112 . The cone angle extends outward like a spike. When the balloon body 110 expands, the cone angle can penetrate into the bone more easily, and the cone angle can increase the friction between the balloon body 110 and the bone, improving the fixation effect of the balloon body 110 . Similarly, structures such as corners and taper angles can be additionally provided on the adjacent parts of the grid rods 111 or the grid holes 112, or integrally formed with the adjacent parts of the grid rods 111 or the grid holes 112, which is not limited in this embodiment.
如图10所示，在第四个优选示例中，嵌入部120包括穿设于所述网格孔112中的杆件121，其中所述杆件121的横截面形状与所述网格孔112的内轮廓形状相适配。可选的，杆件121被配置为可活动地穿设于网格孔112中。如图10所示出的示例中，杆件121大致呈圆柱形，其一端为尖锐端，用于实现穿刺。一部分的网格孔112呈菱形，一部分的网格孔112呈圆形，圆形的网格孔112的内径略大于杆件121的外径。这样在球囊本体110被植入骨质并扩张后，可将杆件121穿入骨质并穿设于网格孔112中。优选的，所述杆件121贯穿所述球囊本体110。需要说明的，杆件121可以是一根，也可以是两根以上，杆件121为两根以上时，优选交叉插设。优选的，在杆件121插入适当的深度后，可剪断露在骨面外的杆件121。As shown in FIG. 10 , in the fourth preferred example, the embedding part 120 includes a rod 121 penetrating through the grid hole 112 , wherein the cross-sectional shape of the rod 121 is adapted to the inner contour shape of the grid hole 112 . Optionally, the rod 121 is configured to be movably passed through the grid hole 112 . In the example shown in FIG. 10 , the rod 121 is substantially cylindrical and has a sharp end at one end for puncturing. A part of the grid holes 112 is diamond-shaped, and a part of the grid holes 112 is circular, and the inner diameter of the circular grid holes 112 is slightly larger than the outer diameter of the rod 121 . In this way, after the balloon body 110 is implanted into the bone and expanded, the rod 121 can be penetrated into the bone and passed through the grid hole 112 . Preferably, the rod 121 runs through the balloon body 110 . It should be noted that there may be one rod 121 or more than two rods 121. When there are more than two rods 121, it is preferred to intersect. Preferably, after the rod 121 is inserted to a proper depth, the rod 121 exposed outside the bone surface can be cut off.
如图11和图12所示，在第五个优选示例中，所述球囊本体110包括沿自身轴向布置的棱柱段113，在所述球囊本体110处于所述扩张状态时，所述棱柱段113的棱边被配置为所述嵌入部120。在一些实施例中，嵌入部120并非必须是额外设置在球囊本体110上的结构，而是可以基于球囊本体110自身的形态来构成。如图11所示出的示范例，球囊本体110的棱柱段113大致为六棱柱形，其六条棱边就可以形成尖锐的边而刺入骨质。进一步的，此时球囊本体110的棱柱段113还兼具有限转的功能，即限制球囊本体110围绕自身轴线周向转动。由此可以减少或防止球囊本体110在植入后受外力而产生跟转。可以理解的，刘棱柱形仅为棱柱段113的一个示例而非限定，在其它的实施例中，棱柱段113也可以是三棱柱、四棱柱、五棱柱或更多棱边的形态，也不局限于必须是正多边形的棱柱形，而可以是不规则形态的棱柱形。As shown in FIG. 11 and FIG. 12 , in a fifth preferred example, the balloon body 110 includes a prism segment 113 arranged along its axial direction, and when the balloon body 110 is in the expanded state, the edges of the prism segment 113 are configured as the embedded portion 120 . In some embodiments, the embedded portion 120 is not necessarily an additional structure provided on the balloon body 110 , but can be formed based on the shape of the balloon body 110 itself. As shown in the example shown in FIG. 11 , the prism section 113 of the balloon body 110 is approximately hexagonal prism, and its six edges can form sharp edges to penetrate into the bone. Further, at this time, the prism section 113 of the balloon body 110 also has the function of limiting rotation, that is, restricting the circumferential rotation of the balloon body 110 around its own axis. In this way, the balloon body 110 can be reduced or prevented from being rotated by an external force after implantation. It can be understood that the Liu prism shape is only an example of the prism section 113 and not limiting. In other embodiments, the prism section 113 can also be in the form of a triangular prism, a quadrangular prism, a pentagonal prism or more edges, and it is not limited to a prism that must be a regular polygon, but can be an irregular prism.
需要说明的，上述若干个优选示例中的嵌入部120的各种结构，不限于独立设置，而是可以相互组合设置的。例如可以在设置棱边、棱角的同时，设置杆件121等，本领域技术人员可根据实际进行合理的组合配置。It should be noted that the various structures of the embedding part 120 in the above several preferred examples are not limited to being independently arranged, but can be arranged in combination with each other. For example, the rods 121 and the like can be provided at the same time as the edges and corners are provided, and those skilled in the art can make a reasonable combination according to the actual situation.
可选的，所述带线锚钉1还包括连接部14，所述连接部14沿所述球囊本体110的轴向与所述球囊本体110连接，所述连接部14用于与推送件22连接，以驱动所述球囊本体110从所述输送管21中脱出并植入预定对象。所述连接部14沿所述球囊本体110的轴向延伸，并具有与所述球囊本体110的轴向成角度方向贯通的穿线孔141。所述连接部14具有沿所述球囊本体110的轴向延伸的容置腔142，所述容置腔142与所述穿线孔141连通，所述容置腔142的横截面尺寸不小于缝线13的横截面尺寸，以允许所述缝线13容置于其中。Optionally, the anchor with wire 1 further includes a connecting portion 14, the connecting portion 14 is connected to the balloon body 110 along the axial direction of the balloon body 110, and the connecting portion 14 is used to connect with the pusher 22, so as to drive the balloon body 110 out of the delivery tube 21 and implant it into a predetermined object. The connecting portion 14 extends along the axial direction of the balloon body 110 , and has a threading hole 141 penetrating in a direction angled to the axial direction of the balloon body 110 . The connecting portion 14 has an accommodating cavity 142 extending axially along the balloon body 110, the accommodating cavity 142 communicates with the threading hole 141, the cross-sectional dimension of the accommodating cavity 142 is not smaller than the cross-sectional dimension of the suture 13, so as to allow the suture 13 to be accommodated therein.
由于带线锚钉1主要用于沿球囊本体110的轴向钉入骨质，为便于操作和驱动，优选将连接部14设置在球囊本体110的近端侧，且朝向近端延伸，以便于操作工具2与其连接。相适配的，操作工具2的远端具有与连接部14的横截面形状相匹配的套筒21，以便于推送球囊本体110。进一步的，基于带线锚钉1的应用需求，一方面其球囊锚定组件10需要能够稳固地锚定在骨上，另一方面球囊锚定组件10还需要能够与缝线13可靠地连接。而缝线13穿设于穿线孔141的方式，即可以简单地实现将缝线13的连接。Since the anchor with wire 1 is mainly used for nailing into bone along the axial direction of the balloon body 110, in order to facilitate operation and driving, it is preferable to arrange the connecting portion 14 on the proximal side of the balloon body 110 and extend toward the proximal end so as to facilitate the connection of the operating tool 2 thereto. Adaptively, the distal end of the operating tool 2 has a sleeve 21 matching the cross-sectional shape of the connecting portion 14 so as to push the balloon body 110 . Further, based on the application requirements of the threaded anchor 1 , on the one hand, the balloon anchoring component 10 needs to be able to be stably anchored on the bone; on the other hand, the balloon anchoring component 10 needs to be able to be reliably connected to the suture 13 . The way that the suture 13 is threaded through the thread hole 141 can simply realize the connection of the suture 13 .
更进一步的，所述连接部14具有沿所述球囊本体110的轴向延伸的容置腔142，所述容置腔142与所述穿线孔141连通，所述容置腔142的横截面尺寸(指垂直于球囊本体110的轴向的横截面的尺寸)不小于缝线13的横截面尺寸，以允许所述缝线13容置于其中。Furthermore, the connecting portion 14 has an accommodating cavity 142 extending in the axial direction of the balloon body 110, the accommodating cavity 142 communicates with the threading hole 141, and the cross-sectional size of the accommodating cavity 142 (referring to the cross-sectional dimension perpendicular to the axial direction of the balloon body 110) is not smaller than the cross-sectional size of the suture 13, so as to allow the suture 13 to be accommodated therein.
为便于操作，缝线13常在带线锚钉1还没有被钉入骨质之前就已经穿设在穿线孔141中。由此操作工具2与连接部14的连接发生在缝线13穿设之后。容置腔142的设置，允许缝线13在平行于连接部14的区段容置在其中，从而可以避免套筒21套设在连接部14时因两者的形状配合而将缝线13挤压割断。如图3和图6所示，在一个优选示例中，容置腔142为凹陷开设于连接部14的槽。当然在其它的一些实施例中，容置腔142也可以是沿球囊本体110的轴向开设的盲孔，其近端开放，远端与穿线孔141连通。For ease of operation, the suture 13 is often set in the threading hole 141 before the anchor with thread 1 is nailed into the bone. The connection of the handling tool 2 to the connecting part 14 thus takes place after the threading of the suture 13 . The setting of the accommodating cavity 142 allows the suture 13 to be accommodated in the section parallel to the connecting portion 14 , thereby avoiding the extrusion and cutting of the suture 13 due to the shape fit between the two when the sleeve 21 is sleeved on the connecting portion 14 . As shown in FIG. 3 and FIG. 6 , in a preferred example, the accommodating cavity 142 is a groove recessed in the connecting portion 14 . Of course, in some other embodiments, the accommodating cavity 142 may also be a blind hole opened along the axial direction of the balloon body 110 , its proximal end is open, and its distal end communicates with the threading hole 141 .
综上所述，在本发明提供的带线锚钉和带线锚钉系统中，所述带线锚钉包括球囊锚定组件；所述球囊锚定组件包括嵌入部和具有自膨性的球囊本体；所述球囊本体被置于输送管内时，受到所述输送管的限制而处于收缩状态；所述球囊本体从所述输送管中脱出并植入预定对象时，所述球囊本体基于自膨性向外扩张而由所述收缩状态转换至扩张状态，以锚定于所述预定对象中；其中，所述球囊本体包括多个网格杆，多个所述网格杆相互交叉连接形成网格孔；在所述球囊本体处于所述扩张状态时，所述嵌入部用于嵌入所述预定对象，并且所述网格孔允许所述预定对象进入。如此配置，在球囊本体从输送管中脱出并植入预定对象(如患者的骨质)时，基于球囊本体的自膨性，其能够从收缩状态转换至扩张状态，从而锚定于预定对象中。并且在该过程中，球囊本体能够根据患者的骨质情况进行自适应调节；基于球囊本体的自膨性，若患者的骨质较硬，则球囊本体的扩张幅度较小，若患者的骨质较疏松，则球囊本体的扩张幅度较大，从而能可靠而稳固地固定在患者的骨质中，满足不同患者的临床需求。此外，带线锚钉的植入过程快速简便，只需将球囊本体从输送管中推出并插入患者的骨质，无需如螺纹固定的方式进行旋拧，而是即刻产生自膨胀，完成固定。进一步的，嵌入部能够嵌入骨质，进一步提高与骨质的连接强度和可靠性，而网格孔允许骨质进入，有利于骨质向内生长融合。To sum up, in the wire anchor and the wire anchor system provided by the present invention, the wire anchor includes a balloon anchoring assembly; the balloon anchoring assembly includes an embedded part and a self-expandable balloon body; when the balloon body is placed in the delivery tube, it is in a contracted state due to the restriction of the delivery tube; when the balloon body is released from the delivery tube and implanted into a predetermined object, the balloon body expands outward based on self-expandability and switches from the contracted state to an expanded state to anchor in the predetermined object; Wherein, the balloon body includes a plurality of grid rods, and the plurality of grid rods are cross-connected to form grid holes; when the balloon body is in the expanded state, the embedding part is used to embed the predetermined object, and the mesh holes allow the predetermined object to enter. So configured, when the balloon body is dislodged from the delivery tube and implanted into a predetermined object (such as a patient's bone), based on the self-expandability of the balloon body, it can switch from a contracted state to an expanded state, thereby being anchored in the predetermined object. And in this process, the balloon body can be adaptively adjusted according to the patient's bone quality; based on the self-expandability of the balloon body, if the patient's bone quality is relatively hard, the expansion range of the balloon body will be small, and if the patient's bone quality is relatively loose, the expansion range of the balloon body will be relatively large, so that it can be reliably and firmly fixed in the patient's bone quality to meet the clinical needs of different patients. In addition, the implantation process of the anchor with wire is quick and easy. It only needs to push the balloon body out of the delivery tube and insert it into the patient's bone. It does not need to be screwed in the way of screw fixation, but self-expands immediately to complete the fixation. Furthermore, the embedding part can be embedded in the bone, further improving the strength and reliability of the connection with the bone, and the grid holes allow the bone to enter, which is beneficial to the in-growth and fusion of the bone.
