技术领域technical field

本发明关于一种笼型支架，特别是一种适用于人体脊椎病变部位，以于术后强化骨组织愈合及稳定性并可轻易塑形的钛基脊椎笼型支架。The present invention relates to a cage-type bracket, in particular to a titanium-based spine cage-type bracket suitable for human spinal lesion to enhance bone tissue healing and stability after surgery and can be easily shaped.

背景技术Background technique

近年来，多数民众因生活习惯的改变长期仰赖电脑工作，而必须长时间屈身坐于办公桌前，加上老龄化社会的演变，以致现今脊椎病变的案例层出不穷，也就使后续脊椎照护的相关问题逐渐受到重视。In recent years, due to changes in living habits, most people rely on computers for long-term work, and have to sit at their desks for a long time. Coupled with the evolution of an aging society, there are endless cases of spinal diseases, which also makes follow-up spinal care. The problem is gradually being taken seriously.

脊椎手术的术后照护为脊椎复原优劣的重要环节，通常于术后，因病人复原速度较其他部位手术缓慢，且无法长时间站立，故多需长期穿着矫正衣，方能避免日常生活的阻碍。Postoperative care after spine surgery is an important link in the recovery of the spine. Usually after surgery, the recovery speed of the patient is slower than that of other parts of the surgery, and the patient cannot stand for a long time. hinder.

为此，现阶段多以脊椎植入物辅助矫正衣，将脊椎植入物置放于脊椎手术后有骨缺损部位的横突间，且同时使用磷酸钙、骨粉、自体骨……等骨填补物填充于该脊椎植入物的开放性空间中，以加速横突间的骨组织愈合。然而，横突间生长较快的软组织常因脊椎植入物的结构不良而容易自孔隙侵入，或者于体内循环系统的流动下带走脊椎植入物内所填充的自体骨或骨粉，以致传统脊椎植入物纵使有填补可加速愈合用的骨填补物，却因经常性的骨填补物流失，而始终无法发挥术后加速骨组织愈合的功效。For this reason, at this stage, spinal implants are often used to assist corrective clothing, and spinal implants are placed between the transverse processes of bone defects after spinal surgery, and bone fillings such as calcium phosphate, bone powder, and autologous bone are used at the same time. It is filled in the open space of the spinal implant to accelerate the healing of bone tissue between transverse processes. However, the soft tissue that grows faster between the transverse processes is often easily invaded from the pores due to the poor structure of the spinal implant, or the autogenous bone or bone powder filled in the spinal implant is taken away by the flow of the circulatory system in the body, so that the traditional Even though spinal implants have bone fillers that can be used to accelerate healing, they are always unable to exert the effect of accelerating bone tissue healing after surgery due to the frequent loss of bone fillings.

如中国台湾公告第M333884号专利案揭示一种模组化骨融合椎笼9，该椎笼9前方设有一圆滑形头部91，该头部91后方纵向开设一槽状空间92，并于该椎笼9二侧壁设有与槽状空间92相通的数个骨融合孔93，且该椎笼9后方另连接有一固定座94，该固定座94用以结合与固定于一骨板固定器95。其中，该槽状空间92可容置经绞碎的自体移植骨、异体移植骨或其他如骨水泥、人造骨等骨填补物。借此，能使该槽状空间92内的骨填补物通过该槽状空间92的上、下开口，而与相邻脊椎椎体相接触，以利于骨融合的进行。For example, the Chinese Taiwan Announcement No. M333884 patent discloses a modular bone fusion vertebral cage 9, a smooth head 91 is provided in front of the vertebral cage 9, and a groove-shaped space 92 is longitudinally provided behind the head 91, and in the vertebral cage 9 Two side walls of the vertebral cage 9 are provided with several bone fusion holes 93 communicating with the groove-shaped space 92, and a fixing seat 94 is connected to the rear of the vertebral cage 9, and the fixing seat 94 is used for combining and fixing to a bone plate fixer 95. Wherein, the groove-shaped space 92 can accommodate minced autograft bone, allograft bone or other bone filling materials such as bone cement and artificial bone. Thereby, the bone filler in the trough-shaped space 92 can pass through the upper and lower openings of the trough-shaped space 92 and contact with adjacent vertebral bodies, so as to facilitate bone fusion.

然而，现有骨融合椎笼9于使用时，不仅需以数骨螺丝96搭配骨板固定器95，方能将骨融合椎笼9限位于骨缺损部位，作为支撑或固定之用。甚至，上述现有骨融合椎笼9仅能适用于椎体之间，且因其结构的繁复，产生有多处的接合界面，而必需以复杂的立体管激光雕刻、放电成形……等技术方能成型，不只相对增加骨融合椎笼9的加工困难度，更衍生有制作成本上的相对负担；加上，于脊椎手术进行时，现有骨融合椎笼9的繁复结构，势必需耗费医护人员相当的操作时间，以致相对提升手术过程可能存在的感染风险。However, when the existing bone fusion cage 9 is used, several bone screws 96 and bone plate fixers 95 are needed to limit the bone fusion cage 9 to the bone defect for support or fixation. Even, the above-mentioned existing bone fusion vertebral cage 9 can only be applied between vertebral bodies, and because of its complicated structure, there are many joint interfaces, and it is necessary to use complicated three-dimensional tube laser engraving, electric discharge forming...etc. It can only be shaped, which not only relatively increases the processing difficulty of the bone fusion cage 9, but also has a relative burden on the production cost; in addition, when the spine operation is performed, the complicated structure of the existing bone fusion cage 9 is bound to consume a lot of money. The operation time of the medical staff is considerable, so that the risk of infection that may exist during the operation is relatively increased.

此外，更因现有骨融合椎笼9的槽状空间92与骨融合孔93的不良设计，始终无法抑止生长快速的软组织侵入，更容易因体内循环系统的流动，而使存在于该槽状空间92内的骨填补物轻易自该骨融合孔93产生流失。如此，传统的骨融合椎笼9终究仅能作为椎体间的支撑及固定之用，完全无法于术后扮演引导组织再生的角色，以致于骨缺损重建的过程依然无法获得实质上的突破，严重影响术后骨组织愈合的效率。In addition, due to the poor design of the groove-shaped space 92 and the bone fusion hole 93 of the existing bone fusion cage 9, it is still impossible to prevent the rapid growth of soft tissue from invading, and it is easier to cause the blood in the groove-shaped space due to the flow of the circulatory system in the body. The bone filler in the space 92 is easily lost from the bone fusion hole 93 . In this way, the traditional bone fusion cage 9 can only be used as support and fixation between vertebral bodies after all, and it cannot play the role of guiding tissue regeneration after surgery at all, so that the process of bone defect reconstruction still cannot obtain a substantial breakthrough. Seriously affect the efficiency of postoperative bone tissue healing.

有鉴于此，确实有必要发展一种于术后强化骨组织愈合及稳定性的钛基脊椎笼型支架，以适用于人体脊椎病变的任意部位，解决如上所述的各种问题。In view of this, it is indeed necessary to develop a titanium-based spinal cage bracket that can strengthen the healing and stability of bone tissue after surgery, so as to be applicable to any part of human spinal lesions and solve the various problems mentioned above.

承上述，本发明脊椎笼型支架可于上述原则下以任意方式进行制作，于此仅以本发明较佳实施例作为举例说明，以简述该脊椎笼型支架的成形过程，如下：In view of the above, the spinal cage bracket of the present invention can be manufactured in any manner under the above principles, and here only the preferred embodiment of the present invention is used as an example to briefly describe the forming process of the spinal cage bracket, as follows:

请再配合参照图2及3所示，选择厚度为50微米的钛箔作为该基体1，以于钛箔表面激光加工成形有数个线槽11，该数个线槽11的弯曲段111呈相对弧形设计，且其中任二相邻线槽11可以圈围形成如圆形、菱形等图纹形式，并同时于该变形支条12的扩径区122内成形孔径为2毫米的数个微孔2，以由任二相邻线槽11之间所形成的变形支条12共同排列为阵列钛网(如图2所示的二维平面形式，该较佳实施例仅以三变形支条为例，以下以“12a、12b及12c”分别称之)，同时利用激光加工于该变形支条12端部成形径宽为0.2毫米的压痕13，特别成形于该变形支条12的左、右相对应侧，且于该基体1上、下表面所形成的压痕13凹面开口呈不同方向；最终，再将成形的阵列钛网浸置于37％盐酸中持续30分钟，以使钛箔表面粗糙度小于1.5微米，而完成本发明脊椎笼型支架的制作。Please refer to Figures 2 and 3 again, select a titanium foil with a thickness of 50 microns as the substrate 1, and form several wire grooves 11 by laser processing on the surface of the titanium foil, and the curved sections 111 of the several wire grooves 11 are opposite to each other. Arc-shaped design, and wherein any two adjacent line grooves 11 can be surrounded to form patterns such as circles and rhombuses, and at the same time, several microscopic holes with a diameter of 2 mm are formed in the enlarged diameter area 122 of the deformed branch 12. Holes 2 are arranged together as an array titanium mesh (two-dimensional plane form as shown in Fig. For example, hereinafter referred to as "12a, 12b and 12c" respectively), and at the same time use laser processing to form an indentation 13 with a diameter width of 0.2 mm at the end of the deformed support 12, especially formed on the left side of the deformed support 12. , the right corresponding side, and the indentation 13 concave openings formed on the upper and lower surfaces of the substrate 1 are in different directions; finally, the formed array titanium mesh is dipped in 37% hydrochloric acid for 30 minutes to make the titanium The surface roughness of the foil is less than 1.5 microns, and the fabrication of the spinal cage bracket of the present invention is completed.

在需要使用时，沿图3所示的箭头方向(即为该基体1的Y方向)施予一外力，以由该基体1相对二侧缘共同朝内挤压，使得二维平面的阵列钛网(也即图2所示的变形支条12a、12b及12c)可以轻易分离，而立即转变为三维立体的中空笼型。其中，该变形支条12a、12c以该第一基准端123及第二基准端124为支点，且顺势将变形应力集中于该压痕13a处，以随该压痕13a的凹面开口方向撑起，朝该基体1的Z方向(即图面所示的上方)推挤变形；另一方面，该变形支条12b则以该第一基准端123及第二基准端124为支点，且同样顺势将变形应力集中于该压痕13b处，以随该压痕13b的凹面开口方向撑起，朝该基体1的Z’方向(即图面所示的下方)推挤变形，借此可由该变形支条12a、12b及12c经变形展开后圈围出一填补空间S(详如图3所示的三维立体形式)，以完成本发明脊椎笼型支架于实际使用时的较佳实施形式。When it needs to be used, an external force is applied along the direction of the arrow shown in Figure 3 (that is, the Y direction of the substrate 1), so that the opposite side edges of the substrate 1 are jointly pressed inward, so that the two-dimensional planar array titanium The net (that is, the deformed struts 12a, 12b and 12c shown in FIG. 2 ) can be easily separated and immediately transformed into a three-dimensional hollow cage. Wherein, the deformed struts 12a, 12c take the first reference end 123 and the second reference end 124 as fulcrums, and concentrate the deformation stress on the indentation 13a along with the trend, so as to prop up along the opening direction of the concave surface of the indentation 13a. , pushing and deforming toward the Z direction of the base 1 (that is, the upper side shown in the drawing); Concentrate the deformation stress on the indentation 13b so as to prop up along the opening direction of the concave surface of the indentation 13b, and push and deform toward the Z' direction of the substrate 1 (that is, the bottom shown in the figure), so that the deformation can The branches 12a, 12b and 12c are deformed and expanded to enclose a filling space S (the three-dimensional form shown in Figure 3 for details), so as to complete the preferred implementation form of the spinal cage bracket of the present invention in actual use.

注意的是，上述仅以最简形式说明之，故于相同原则下，该脊椎笼型支架的长度(意指该变形支条12于该基体1形成阵列的数目)可依需求而定，特别以能符合2-3节脊椎厚度为较佳，而同样在外力挤压下，呈现如图3所示的任二相邻变形支条12呈上、下交错的变形形式即可，属本领域技术人员依据上述原则可轻易思及且加以应用，于此不再逐一赘述。It should be noted that the above is only described in the simplest form, so under the same principle, the length of the vertebral cage (meaning the number of arrays formed by the deformed struts 12 on the base 1) can be determined according to requirements, especially It is better to meet the thickness of 2-3 vertebrae, and under the same external force extrusion, any two adjacent deformed struts 12 as shown in Figure 3 are deformed in a staggered up and down form, which belongs to this field Those skilled in the art can easily conceive and apply based on the above principles, and details are not repeated here.

由于基体1的任二相邻的变形支条12朝不同方向相互远离而圈围出该填补空间S，因此，位于填补空间S同一侧的数个变形支条12成间隔排列而形成至少一空隙G，该空隙G的外形即等同于一变形支条12的外形。于使用时，容置于填补空间S内的骨填补物借助该空隙G与骨组织接触，因此，扩径区122的径宽尺寸应小于骨填补物的大小较为适当，扩径区122的径宽选择为1.5-4.5毫米，较佳选择为2-4毫米，使得骨填补物不会经由该空隙G渗出而流失，以达到限制骨填补物的移动空间的较佳功效，并供予骨填补物能自该空隙G与骨组织接触，进而加速骨组织再生愈合的效率。Since any two adjacent deformed struts 12 of the base body 1 move away from each other in different directions to enclose the filling space S, therefore, several deformed struts 12 on the same side of the filling space S are arranged at intervals to form at least one gap G, the shape of the gap G is equal to the shape of a deformed strut 12 . When in use, the bone filling material contained in the filling space S is in contact with the bone tissue through the gap G. Therefore, the diameter width of the enlarged diameter area 122 should be smaller than the size of the bone filling material. The width selection is 1.5-4.5 mm, and the preferred selection is 2-4 mm, so that the bone filling material will not seep through the gap G and be lost, so as to achieve the best effect of limiting the moving space of the bone filling material and supply bone The filler can contact the bone tissue through the gap G, thereby accelerating the regeneration and healing efficiency of the bone tissue.

除上述之外，本发明脊椎笼型支架也可以选择成形有不同弯曲段111形式的数个线槽11，以通过该数个线槽11的弯曲段111曲型设计，便能增加变形后该变形支条12的顺畅度，进而避免因角状设计所造成的扭转断裂及伤害，以同时提升该变形支条12于变形后的支撑强度。In addition to the above, the spinal cage bracket of the present invention can also be selected to have several wire slots 11 formed with different curved sections 111, so that the bending section 111 curved design of the several wire slots 11 can increase the number of wire slots after deformation. The smoothness of the deformed support bar 12 can avoid torsional fracture and damage caused by the angular design, and at the same time improve the support strength of the deformed support bar 12 after deformation.
