本发明属于医疗器械技术领域，具体涉及一种椎板间棘突稳定装置。The invention belongs to the technical field of medical devices, and specifically relates to an interlaminar spinous process stabilizing device.
背景技术Background technique
人体的脊椎是由多节椎体所组成，前方较厚的圆形结构是椎体，椎体后方是椎管，椎管后方有个向后方凸起的骨性结构，称为棘突。棘突不仅位置比较表浅，还有承上启下的作用，棘突上附着有很多韧带，上下节的棘突有棘间韧带和棘上韧带，能把不同段的脊椎联系起来。脊柱疾病会导致严重的病状，这些疾病包括椎骨、椎间盘、椎小关节和围绕脊柱的连接组织的异常，这些异常可能源于多种原因，包括机械损伤或椎间盘退变性疾病。这些异常可导致脊柱不稳定，使脊柱变得不齐整并在相邻椎骨间产生微动，脊椎不齐整和微动可能导致脊椎骨表面磨损并最终引起剧烈的疼痛。此外,这些疾病常常是慢性的和会逐渐加重的问题。The human spine is composed of multiple vertebral bodies. The thicker circular structure in front is the vertebral body, and behind the vertebral body is the spinal canal. Behind the spinal canal, there is a bony structure that bulges toward the rear, called the spinous process. Not only is the spinous process relatively superficial, it also serves as a link between the upper and lower segments. There are many ligaments attached to the spinous process. The spinous processes of the upper and lower segments have interspinous ligaments and supraspinal ligaments, which can connect different segments of the spine. Spinal disorders can lead to serious pathology and include abnormalities in the vertebrae, discs, facet joints, and connecting tissue surrounding the spine, which can result from a variety of causes, including mechanical injury or degenerative disc disease. These abnormalities can lead to spinal instability, causing the spine to become misaligned and produce micro-motions between adjacent vertebrae. Spinal misalignments and micro-movements can cause the surface of the vertebrae to wear away and ultimately cause severe pain. In addition, these diseases are often chronic and progressive problems.
外科手术技术如脊椎融合对于治疗脊椎病是必要的，脊椎融合通常在脊椎无法正确实施主要功能或由于退化或错乱而影响相关神经时被使用，脊椎融合涉及通过外科手术方法被定位以在邻近椎骨之间形成桥接部并稳固邻近椎骨的人造合成融合器。现有的椎间隙-椎板间融合器一般采用填充块放置在椎间，然后加以钉棒系统(或单独)固定在两节椎体间，用于实现椎体的固定和稳定，最后完成椎间的融合。现有的椎板间棘突稳定装置对病人的骨组织破坏性较大，不利于后期的恢复。Surgical techniques such as spinal fusion are necessary to treat spondylosis. Spinal fusion is often used when the spine is unable to properly perform its primary functions or has affected the associated nerves due to degeneration or derangement. Spinal fusion involves surgical procedures that are positioned to connect adjacent vertebrae. A synthetic cage that forms a bridge between vertebrae and stabilizes adjacent vertebrae. The existing intervertebral space-interlaminar fusion cage generally uses filling blocks to be placed between the vertebrae, and then fixed between the two vertebral bodies with a nail rod system (or alone) to achieve the fixation and stability of the vertebral body, and finally complete the vertebral body. fusion between. The existing interlaminar spinous process stabilization device is highly destructive to the patient's bone tissue and is not conducive to later recovery.
