背景技术Background technique

随着人口老龄化的加剧，以颈肩痛及腰腿痛为主要症状的脊柱退行性疾病正严重地影响人们的工作和生活。在椎体间进行椎体融合术是目前治疗脊柱退行性疾病主要方法之一。自从Kuslich于1988年首次将椎间融合器用于腰椎椎间融合术以来，各种材质的椎间融合器相继问世，并逐步应用于临床。With the aging of the population, spinal degenerative diseases with neck and shoulder pain and low back and leg pain as the main symptoms are seriously affecting people's work and life. Vertebral fusion between vertebral bodies is one of the main methods for the treatment of spinal degenerative diseases. Since Kuslich first used the interbody cage for lumbar interbody fusion in 1988, interbody cages of various materials have come out one after another and have been gradually used in clinical practice.

经过科学家们的不懈努力，各种各样的椎间融合器相继开发出来并逐步应用于临床。理想的椎间融合器要求能纠正脊柱畸形，恢复正常的生理曲度，保持椎间间隙的稳定，并且最重要的是促进骨融合。但是现在的融合器仍然存在很多的不足，包括融合器材料生物相容性的问题、椎间隙塌陷、迟发性炎症反应等等。Through the unremitting efforts of scientists, a variety of interbody cages have been developed and gradually applied in clinical practice. The ideal cage needs to correct spinal deformities, restore normal physiological curvature, maintain intervertebral space stability, and most importantly, promote bone fusion. However, there are still many deficiencies in current cages, including the biocompatibility of cage materials, intervertebral space collapse, delayed inflammatory response, and so on.

为了提高椎间融合器的复位力，如图1至图5所示，在本实施例中，椎间融合器包括：第一支撑件10、第二支撑件20、多个弹性筋30以及硅胶件40。第二支撑件20设置于第一支撑件10的下方。多个弹性筋30间隔设置于第一支撑件10和第二支撑件20之间。硅胶件40设置于第一支撑件10和第二支撑件20之间。其中，多个弹性筋30中的部分弹性筋30位于硅胶件40的内部，其余的弹性筋30围绕在硅胶件40的外部。In order to improve the restoring force of the intervertebral cage, as shown in FIGS. 1 to 5 , in this embodiment, the intervertebral cage includes: afirst support 10 , asecond support 20 , a plurality ofelastic ribs 30 andsilicone Piece 40. Thesecond support member 20 is disposed below thefirst support member 10 . A plurality ofelastic ribs 30 are disposed between thefirst support member 10 and thesecond support member 20 at intervals. Thesilicone member 40 is disposed between thefirst support member 10 and thesecond support member 20 . Wherein, some of theelastic ribs 30 of the plurality ofelastic ribs 30 are located inside thesilicone part 40 , and the rest of theelastic ribs 30 surround the outer part of thesilicone part 40 .

应用本实施例的技术方案，多个弹性筋30间隔设置在第一支撑件10和第二支撑件20之间，同时，在第一支撑件10和第二支撑件20之间还设置有硅胶件40。多个弹性筋30中的部分弹性筋30设置在硅胶件40的内部，其余的弹性筋30位于硅胶件40的外部。通过上述的设置，在椎间融合器植入后，弹性筋30和硅胶件40被压缩变形，但是由于弹性筋30和硅胶件40均具有弹性力，因此，弹性筋30和硅胶件40能够对第一支撑件10和第二支撑件20起到支撑的作用，并且硅胶件40能够降低弹性筋30无法复原的可能性。同时，位于硅胶件40外侧的弹性筋30能够对硅胶件40起到限位的作用，使得硅胶件40的位置稳定，不容易从第一支撑件10和第二支撑件20之间脱出。因此本实施例的技术方案有效地解决了相关技术中的弹性筋的形状无法复原进而导致患者的使用效果较差的问题。Applying the technical solution of this embodiment, a plurality ofelastic ribs 30 are arranged between thefirst support member 10 and thesecond support member 20 at intervals, and at the same time, silica gel is also arranged between thefirst support member 10 and thesecond support member 20Piece 40. Some of theelastic ribs 30 of the plurality ofelastic ribs 30 are disposed inside thesilicone part 40 , and the rest of theelastic ribs 30 are located outside thesilicone part 40 . Through the above arrangement, after the interbody cage is implanted, theelastic rib 30 and thesilicone part 40 are compressed and deformed, but since theelastic rib 30 and thesilicone part 40 both have elastic force, theelastic rib 30 and thesilicone part 40 can Thefirst support member 10 and thesecond support member 20 play a supporting role, and thesilicone member 40 can reduce the possibility that theelastic rib 30 cannot be restored. At the same time, theelastic rib 30 on the outer side of thesilicone part 40 can limit the position of thesilicone part 40 , so that the position of thesilicone part 40 is stable, and it is not easy to come out from between thefirst support 10 and thesecond support 20 . Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the shape of the elastic rib cannot be restored, which leads to poor use effect for patients.

需要说明的是，上述的多个弹性筋30中的部分弹性筋30位于硅胶件40的内部可以是一个弹性筋30位于硅胶件40的内部，也可以是多个弹性筋30设置在硅胶件40的内部。硅胶件40是通过注塑的方式进行设置的。It should be noted that, some of theelastic ribs 30 in the above-mentioned plurality ofelastic ribs 30 are located inside thesilicone part 40 , and oneelastic rib 30 may be located in the inner part of thesilicone part 40 , or a plurality ofelastic ribs 30 may be arranged in thesilicone part 40 . internal. Thesilicone part 40 is set by injection molding.

考虑到硅胶件的固定以及椎间融合器的整体的弹性形变的变化量，如图1至图6所示，在本实施例中，弹性筋30为弧形，弹性筋30包括多个第一弹性筋31和多个第二弹性筋32，多个第二弹性筋32位于多个第一弹性筋31的内侧，第二弹性筋32位于硅胶件40的内部，第一弹性筋31围绕在硅胶件40的外部。弧形的弹性筋30便于被压缩，同时，弧形的弹性筋30也容易复位。因此将弹性筋30设置为弧形是为了兼顾压缩性能和复位能力的。第一弹性筋31和第二弹性筋32的设置也是为了进一步提高椎间融合器的弹性复位的能力。Considering the fixation of the silicone piece and the variation of the overall elastic deformation of the intervertebral cage, as shown in FIGS. 1 to 6 , in this embodiment, theelastic rib 30 is arc-shaped, and theelastic rib 30 includes a plurality offirst Elastic ribs 31 and a plurality of secondelastic ribs 32, the plurality of secondelastic ribs 32 are located inside the plurality of firstelastic ribs 31, the secondelastic ribs 32 are located inside thesilicone part 40, and the firstelastic ribs 31 are surrounded by the silicone outside ofpiece 40. The arc-shapedelastic rib 30 is easy to be compressed, and at the same time, the arc-shapedelastic rib 30 is also easy to reset. Therefore, the purpose of setting theelastic rib 30 in an arc shape is to take into account both the compression performance and the restoring ability. The arrangement of the firstelastic rib 31 and the secondelastic rib 32 is also to further improve the elastic reset capability of the intervertebral cage.

为了避免第一弹性筋相互之间发生干涉，如图1至图6所示，在本实施例中，第一弹性筋31的第一端与第一支撑件10的边缘处连接，第一弹性筋31的第二端对应地连接于第二支撑件20的边缘处，多个第一弹性筋31在第一支撑件10的周向方向上间隔设置。第一弹性筋31设置在第一支撑件10的边缘处，同时第一弹性筋31连接在第二支撑件20的边缘处，这样的设置方式能够有效地将硅胶件40固定在第一支撑件10和第二支撑件20之间。In order to avoid mutual interference between the first elastic ribs, as shown in FIG. 1 to FIG. 6 , in this embodiment, the first end of the firstelastic rib 31 is connected to the edge of thefirst support member 10 , and the first elastic The second ends of theribs 31 are correspondingly connected to the edge of thesecond support member 20 , and a plurality of firstelastic ribs 31 are arranged at intervals in the circumferential direction of thefirst support member 10 . The firstelastic rib 31 is arranged at the edge of thefirst support member 10, and at the same time the firstelastic rib 31 is connected to the edge of thesecond support member 20. This arrangement can effectively fix thesilicone piece 40 on the first support member. 10 and thesecond support 20 .

需要说明的是，上述的对应地是指第一弹性筋31的第一端和第一弹性筋31的第二端是在一条竖直的线上，或者该竖直的线与水平面之间具有锐角夹角，该夹角在75°至90°之间。It should be noted that the above correspondingly means that the first end of the firstelastic rib 31 and the second end of the firstelastic rib 31 are on a vertical line, or there is a vertical line between the vertical line and the horizontal plane. Acute angle, which is between 75° and 90°.

如图1至图6所示，在本实施例中，每个第一弹性筋31的一部分凸出于第一支撑件10和第二支撑件20。第一弹性筋31的中部凸出于第一支撑件10和第二支撑件20，这样的设置方式，使得椎间融合器被压缩的时候，第一弹性筋31具有较大的变形的空间，并且多个第一弹性筋31不会发生相互的干涉。As shown in FIGS. 1 to 6 , in this embodiment, a part of each firstelastic rib 31 protrudes from thefirst support member 10 and thesecond support member 20 . The middle portion of the firstelastic rib 31 protrudes from thefirst support member 10 and thesecond support member 20. This arrangement allows the firstelastic rib 31 to have a large deformation space when the intervertebral cage is compressed. In addition, the plurality of firstelastic ribs 31 will not interfere with each other.

需要说明的是，上述的第一支撑件10在水平面上的投影完全遮挡第二支撑件20。It should be noted that the above-mentioned projection of thefirst support member 10 on the horizontal plane completely blocks thesecond support member 20 .

为了提高支撑强度和弹性力，如图2和图6所示，在本实施例中，第二弹性筋32连接在第一支撑件10和第二支撑件20之间，多个第二弹性筋32具有多个中心线，多个中心线的至少部分位于同一平面上。多个第二弹性筋32的至少部分多个中心线在同一平面上，这样使得多个第二弹性筋32的弹性力的施力范围在同一个区域内，这样使得支撑的强度更好。在保证椎间融合器发生变形的前提下，能够使得椎间融合器的结构强度较好。In order to improve the support strength and elastic force, as shown in FIG. 2 and FIG. 6 , in this embodiment, the secondelastic ribs 32 are connected between thefirst support member 10 and thesecond support member 20 , and a plurality of secondelastic ribs 32 has a plurality of centerlines, at least portions of which lie on the same plane. At least some of the centerlines of the plurality of secondelastic ribs 32 are on the same plane, so that the force application range of the elastic force of the plurality of secondelastic ribs 32 is in the same area, so that the strength of the support is better. On the premise of ensuring the deformation of the intervertebral cage, the structural strength of the intervertebral cage can be improved.

如图2和图6所示，在本实施例中，第二弹性筋32设置于第一支撑件10的对称线上，多个第二弹性筋32的多个弯曲度由靠近第一支撑件10的中心位置至靠近第一支撑件10的边缘处逐渐增大。第二弹性筋32设置在第一支撑件10的对称线上，即也位于第二支撑件20的对称线上。这样的设置使得第二弹性筋32能够提高固定位置的支撑强度。相邻的两个第二弹性筋32中靠近第一支撑件10的中心的第二弹性筋32的弯曲度小于远离第二弹性筋32的弯曲度。例如在人体颈椎左右侧弯时，左右方向受到较大的压力，当左侧受到压力压缩，则右侧张起，反之同理。将第二弹性筋32设置在第一支撑件10的左右方向上，这样能够使得椎间融合器具有更好的支撑效果和弹性变形的效果。进而能够使得患者的使用效果更好，同时能够提高椎间融合器的使用寿命。As shown in FIG. 2 and FIG. 6 , in this embodiment, the secondelastic ribs 32 are disposed on the symmetry line of thefirst support member 10 , and the curvatures of the plurality of secondelastic ribs 32 are determined by being close to the first support member. The central position of the 10 gradually increases toward the edge of thefirst support member 10 . The secondelastic rib 32 is disposed on the symmetry line of thefirst support member 10 , that is, also located on the symmetry line of thesecond support member 20 . Such arrangement enables the secondelastic rib 32 to improve the support strength of the fixed position. Among the two adjacent secondelastic ribs 32 , the bending degree of the secondelastic ribs 32 close to the center of thefirst support member 10 is smaller than the bending degree of the secondelastic ribs 32 away from the secondelastic ribs 32 . For example, when the human cervical spine is bent left and right, the left and right directions are subjected to greater pressure. When the left side is compressed by the pressure, the right side is stretched, and vice versa. The secondelastic rib 32 is arranged in the left-right direction of thefirst support member 10, so that the intervertebral cage can have better supporting effect and elastic deformation effect. Further, the use effect of the patient can be better, and the service life of the interbody cage can be improved at the same time.

需要说明书的是，椎间融合器的第一支撑件10和第二支撑件20为规则形状，包括矩形、圆形以及椭圆形等。具体地，本实施例的第一支撑件10为椭圆形，其对称线为椭圆形的长轴或者短轴。It should be noted that thefirst support member 10 and thesecond support member 20 of the interbody cage are in regular shapes, including rectangular, circular, and oval shapes. Specifically, thefirst support 10 in this embodiment is elliptical, and the symmetry line thereof is the long axis or the short axis of the ellipse.

弹性筋30的截面为圆形，弹性筋30的材质为碳纤维。弹性筋的截面为圆形。The cross section of theelastic rib 30 is circular, and the material of theelastic rib 30 is carbon fiber. The cross-section of the elastic rib is circular.

在图中未示出的实施例中，弹性筋的截面为多边形或者椭圆形。In the embodiment not shown in the drawings, the cross-section of the elastic rib is polygonal or elliptical.

为了避免椎间融合器植入后产生移动，导致椎间融合器的位置不固定。如图4、图5以及图7所示，在本实施例中，第一支撑件10和第二支撑件20上设置有多个防滑筋50，多个防滑筋50由第一支撑件10和第二支撑件20的中心位置呈放射状设置。防滑筋50的设置使得椎间融合器在植入后，第一支撑件10和第二支撑件20与人体骨结构之间的摩擦力较大，能够有效地使得椎间融合器的位置固定。并且，防滑筋50的结构简单，便于设置。由于椎间融合器在植入后具有多个运动的方向，因此将防滑筋50设置为放射状，这样能够有效地提高多个运动方向的摩擦阻力。进而使得椎间融合器的位置固定，不易松动。In order to avoid the movement of the cage after implantation, the position of the cage is not fixed. As shown in FIG. 4 , FIG. 5 and FIG. 7 , in this embodiment, a plurality ofanti-skid ribs 50 are provided on thefirst support member 10 and thesecond support member 20 , and the plurality ofanti-skid ribs 50 are formed by thefirst support member 10 and thesecond support member 20 . The center position of thesecond support member 20 is radially arranged. The setting of theanti-slip ribs 50 makes the friction between thefirst support member 10 and thesecond support member 20 and the human bone structure larger after the cage is implanted, which can effectively fix the position of the cage. In addition, the structure of theanti-skid rib 50 is simple and easy to install. Since the intervertebral cage has multiple moving directions after implantation, theanti-slip ribs 50 are arranged in a radial shape, which can effectively improve the frictional resistance in multiple moving directions. Thus, the position of the intervertebral cage is fixed, and it is not easy to loosen.

如图1至图5以及图7所示，在本实施例中，第一支撑件10和第二支撑件20上设置有凸刺60，凸刺60位于第一支撑件10和第二支撑件20的中心位置。凸刺60的设置是为了进一步地提高椎间融合器的防滑性能，提高椎间融合器的稳定性。As shown in FIG. 1 to FIG. 5 and FIG. 7 , in this embodiment, thefirst support member 10 and thesecond support member 20 are provided withthorns 60 , and thethorns 60 are located on thefirst support member 10 and the second support member. 20 in the center. The arrangement of the protruding spurs 60 is to further improve the anti-slip performance of the intervertebral cage and improve the stability of the intervertebral cage.

如图1至图5所示，在本实施例中，第一支撑件10和第二支撑件20为平直板。平直板的结构便于设置，能够降低加工难度。As shown in FIG. 1 to FIG. 5 , in this embodiment, thefirst support member 10 and thesecond support member 20 are flat plates. The structure of the flat plate is easy to set and can reduce the difficulty of processing.

在图中未示出的实施例中，第一支撑件10和第二支撑件20为弧形板。或者第一支撑件为平直板，第二支撑件为弧形板。In an embodiment not shown in the figures, thefirst support member 10 and thesecond support member 20 are arc-shaped plates. Alternatively, the first support member is a flat plate, and the second support member is an arc-shaped plate.

在本实施例的技术方案中，第一支撑件10和第二支撑件20能够较好地与上下相邻的肢体融合，进而使得椎间融合器与上下椎体接触更加稳定。弹性筋30的设置为椎间融合器提供了弹性，使得其具有变形的能力。硅胶件40的设置一方面是为了提高弹性力，以使椎间融合器具有较好的弹性力；另一方面能够发挥占位的作用，为弹性筋30提供了保护效果，能够避免弹性筋30收到过大的压力导致其断裂。具体地，弹性筋30的材质为碳纤维，碳纤维材质具有重量轻但承重能力强的特点，这使得椎间融合器兼顾了重量和强度。在第一支撑件10和第二支撑件20上均涂有生物涂层，通过生物涂层，以使椎间融合器能够更好地与上下椎骨连接。In the technical solution of this embodiment, thefirst support member 10 and thesecond support member 20 can better fuse with the upper and lower adjacent limbs, thereby making the contact between the intervertebral cage and the upper and lower vertebral bodies more stable. The arrangement of theelastic rib 30 provides elasticity for the intervertebral cage, so that it has the ability to deform. On the one hand, the arrangement of thesilicone piece 40 is to improve the elastic force, so that the intervertebral cage has better elastic force; Excessive pressure caused it to break. Specifically, the material of theelastic rib 30 is carbon fiber, and the carbon fiber material has the characteristics of light weight but strong load-bearing capacity, which makes the intervertebral cage take into account both weight and strength. Both thefirst support member 10 and thesecond support member 20 are coated with a biological coating, so that the intervertebral cage can be better connected with the upper and lower vertebrae through the biological coating.

在本实施例中，图1至图7均为示意图。图1、图2以及图6中仅示意出部分的第二弹性筋。图3至图5中未示出第二弹性筋。In this embodiment, FIGS. 1 to 7 are schematic diagrams. Only a part of the second elastic rib is shown in FIGS. 1 , 2 and 6 . The second elastic rib is not shown in FIGS. 3 to 5 .

如图1至图7所示，本实施例的技术方案是先将第一支撑件10、第二支撑件20以及弹性筋30连接好并固定。形成一个框架，再通过注塑的方式将硅胶件40注塑到上述框架的内部，这样使得硅胶件40包覆住第二弹性筋32，第一弹性筋31位于硅胶件40的外侧。As shown in FIGS. 1 to 7 , the technical solution of this embodiment is to first connect and fix thefirst support 10 , thesecond support 20 and theelastic rib 30 . A frame is formed, and then thesilicone part 40 is injected into the inside of the frame by injection molding, so that thesilicone part 40 covers the secondelastic rib 32 , and the firstelastic rib 31 is located outside thesilicone part 40 .

在本发明的描述中，需要理解的是，方位词如“前、后、上、下、左、右”、“横向、竖向、垂直、水平”和“顶、底”等所指示的方位或位置关系通常是基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，在未作相反说明的情况下，这些方位词并不指示和暗示所指的装置或元件必须具有特定的方位或者以特定的方位构造和操作，因此不能理解为对本发明保护范围的限制；方位词“内、外”是指相对于各部件本身的轮廓的内外。In the description of the present invention, it should be understood that the orientations indicated by orientation words such as "front, rear, top, bottom, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" etc. Or the positional relationship is usually based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and these orientation words do not indicate or imply the indicated device or element unless otherwise stated. It must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be construed as a limitation on the protection scope of the present invention; the orientation words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。For ease of description, spatially relative terms, such as "on", "over", "on the surface", "above", etc., may be used herein to describe what is shown in the figures. The spatial positional relationship of one device or feature shown to other devices or features. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or features would then be oriented "below" or "over" the other devices or features under other devices or constructions". Thus, the exemplary term "above" can encompass both an orientation of "above" and "below." The device may also be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptions used herein interpreted accordingly.

此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本发明保护范围的限制。In addition, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing corresponding components.
