Description

腰椎椎体间固定融合器 Fixed lumbar interbody fusion cage

技术领域 FIELD

本发明属于医疗用接骨器具技术领域。 The present invention belongs to the technical field of medical instrument for bone.

背景技术 Background technique

骨科医疗实践中,遇到摘除腰椎间盘突出后出现的脊柱不稳定,或退行性腰椎间盘病变脊柱不稳定,或I°~II°脊柱滑脱等情况,常在椎体间放置用金属材料制成的内固定支架-Cage进行治疗处理。 Orthopedic medical practice, after removal of spinal instability encountered lumbar disc, lumbar degenerative disc disease, or spinal instability, or where I ° ~ II ° spondylolisthesis and the like, often placed between vertebral bodies of a metal member internal fixation -Cage therapeutic treatment. 如几年前流行的TFC、BAK,因承载面小,填充接骨后会引起下沉与滑脱等并发症,且安装不便,已被最近流行的Contact Fusion Cage(如TELAMON、OIC-Titanium、OIC-Peek)所代替。 A few years ago as the popular TFC, BAK, due to the small bearing surfaces, after filling the bone subsidence and spondylolisthesis can cause complications, and inconvenient to install, has been popular recently Contact Fusion Cage (eg TELAMON, OIC-Titanium, OIC- PEEK) replaced. 然而,不论是前者还是后者,所有这些内固定物几乎均是金属框架结构的异物,而高分子聚合物的OIC-PEEK降解较快,且框架内均要填充植骨,故被认为不够理想。 However, whether former or the latter, almost all of which are within the fixture foreign metal frame structure, and OIC-PEEK polymers rapid degradation, and have to be filled with bone graft within the framework, it was considered enough for .

发明内容 SUMMARY

本发明的目的,就是要提供一种既可作为椎体间的支撑固定物,又可作为椎体间的植骨填充物的固定融合器。 Object of the present invention is to provide a fixture as a support between both vertebrae, the cage but also as a fixed filler interbody graft.

本发明的技术解决方案是,一种腰椎椎体间固定融合器,参见图1-2,具有本体4,所述本体4取材新鲜健康的哺乳动物骨骼制作,取材新鲜健康的哺乳动物骨骼制作的该本体4呈椎台形,本体4两侧椎面分别分布有凸齿1,本体4两侧平面开有二个以上通孔3,本体4两侧平面朝向上底面一端开有条形凹槽2。 Technical Solution The present invention is an inter-vertebral fixation and fusion, see Figure 1-2, having a body 4, the body 4 is drawn from a healthy mammal bones prepared fresh, freshly drawn healthy mammal bones prepared the main body 4 has a truncated cone-shaped surface of the body 4, respectively, on both sides of the vertebral distributed teeth 1, 4 sides apart planar body having at least two through holes 3, 4 on both sides of the bottom surface toward the upper planar body is opened at one end a groove strip 2 .

本发明的这种腰椎椎体间固定融合器取材新鲜健康的哺乳动物骨骼机械加工成如上述其本体呈椎台形,见图1。 Such inter-vertebral cage of the present invention is fixed in a mammal drawn fresh and healthy bones as described above which is machined to present a substantially truncated cone-shaped, see Fig. 截面呈'工'字形之弹头状,见图2。 Cross section 'station' of the bullet-like shape, shown in Figure 2. 该融合器本体前端圆滑呈流线形,故可减小植入阻力避免神经损伤。 The fusion was sleek streamlined body distal end, so that resistance can be reduced to avoid implantable nerve injury. 而本体两侧椎面又分别分布有凸齿1,可与上下终板相啮合。 And both the vertebral body surfaces and are distributed teeth 1, may be engaged with the upper and lower end plates. 成品腰椎椎体间固定融合器可以经灭菌处理后备用。 Finished lumbar interbody fusion between the fixing may be sterilized after use. 本腰椎椎体间固定融合器有较大的机械强度,可用于腰椎后路椎体间的支撑固定和融合。 This is fixed between lumbar interbody fusion has greater mechanical strength, for supporting and fixing posterior lumbar fusion between the vertebrae. 用骨骼材料制成的本接骨器具有无毒、无致癌性与无过敏反应,与人体组织相容性好,可缓慢吸收融合,且用专用工具安装较为方便,故可认为是一种理想的L1~S1后路椎体间固定融合器。 This bone with the bone material is non-toxic, non-carcinogenic and non-allergic reaction, good compatibility with human tissue, may be slowly absorbed fusion, and is mounted with a special tool more convenient, it can be considered an ideal L1 ~ S1 between the fixed posterior lumbar fusion.

本发明的成品投入医疗使用时,可遵循下述方式。 When the finished product is put into the medical use of the present invention, it can follow the following manner. 将椎间盘摘除后,清净椎体软骨面,用专用融合器夹持钳夹持融合器凹槽2,将融合器横行送入椎间隙,注意位置适当,然后旋转90°,让融合器工字梁支撑和紧密接触椎体终板,退出夹持钳,融合器呈椎形带凸齿的结构使之磨擦加大结合紧密,故不会随着夹持器退出。 After discectomy, clean vertebral cartilage, gripping tongs clamping groove with a dedicated fusion cage 2, the fusion device into the intervertebral space transverse, note that the proper position, then rotated 90 °, so that the cage-beam close contact and support the vertebral end plate, exit gripping clamp, as a fusion with a cone-shaped configuration so that the teeth tightly bound to increase friction, it will not exit with the holder. 融合器上通孔的作用是为自体骨日后长入提供方便,以利于骨融合。 Through holes on the cage effect is to facilitate future autologous bone ingrowth, in order to facilitate bone fusion.

应该指出的是,包括同种和异种骨骼加工成的腰椎椎体间固定融合器都应落在本发明的保护范围之内。 It should be noted that the same species and between heterogeneous processing including into the vertebral bone fixation cage should fall within the scope of the present invention.

本发明采用骨骼组织作材料,无免疫抗原性,其抗压强度大,具有极高的机械性能和影像兼容性,适合于腰椎后路椎体间的支撑固定和融合需要。 The present invention employs as a bone tissue material, non-immunogenicity, high compressive strength, has a very high mechanical properties and imaging compatibility, fixed and adapted to support the posterior lumbar fusion between the vertebral bodies needed.

本发明取材方便,质量安全可靠,易于安装应用。 The present invention is drawn convenient, safe and reliable quality, easy to install the application. 以生物材料取代金属材料,符合人体生理需要。 Biomaterial substituted metal material, meet the physiological needs.
