Description
技术领域：Technical field:
本发明涉及一种脊柱内固定装置。The invention relates to a spinal internal fixation device.
背景技术：Background technique:
脊柱损伤因产生原因不同，可以简单分为几个类别：Spinal injuries can be simply divided into several categories due to different causes:
单纯性契形压缩性骨折 这是脊柱前柱损伤的结果。暴力来自沿着X轴旋转的力量，使脊柱向前屈曲所致，后方的结构很少受影响，椎体通常成契形。该型骨折不损伤中柱，脊柱仍保持其尊稳定性。此类骨折通常为高空坠落伤、足、臀部着地，身体猛烈屈曲，产生了椎体前半部分压缩。 稳定性爆破型骨折 这是脊柱前柱和中柱损伤的结果。暴力来自Y轴的轴向压缩。通常亦为高空坠落伤，足臀部着地，脊柱保持正直，胸腰段脊柱的椎体受力最大，因挤压而破碎，由于不存在旋转力量，脊柱的后柱则不受影响，因而仍保留了脊柱的稳定性，但破碎的椎体与椎间盘可以突出于椎管前方，损伤了脊髓而产生神经症状。 Simple wedge compression fracture This is the result of an injury to the anterior column of the spine. Violence comes from forces that rotate along the X-axis, causing the spine to flex forward. The posterior structures are rarely affected, and the vertebral bodies are usually tapered. This type of fracture does not damage the central column, and the spine maintains its stability. This type of fracture is usually caused by a fall from a height, where the foot and hip land on the ground, and the body flexes violently, resulting in compression of the anterior part of the vertebral body. Stable Blast Fracture This is the result of injury to the anterior and central columns of the spine. Violence comes from axial compression of the Y axis. Usually it is also a high-altitude fall injury. The feet and buttocks are on the ground, and the spine remains upright. The vertebral body of the thoracolumbar spine is the most stressed, and it is crushed due to extrusion. Since there is no rotational force, the posterior column of the spine is not affected, so it is still retained. The stability of the spine is improved, but the broken vertebral body and intervertebral disc can protrude from the front of the spinal canal, damaging the spinal cord and causing neurological symptoms. ``
不准定性爆破型骨折 这是前、中、后三柱同时损伤的结果。暴力来自Y轴的轴向压缩以及顺时针的旋转，可能还有沿着Z轴的旋转力量参与，使后柱亦出现断裂，由于脊柱不稳定，会出现创伤后脊柱后突和进行性神经症状。 Indeterminate blasting fracture This is the result of simultaneous damage to the front, middle and rear columns. Violence from axial compression in the Y-axis and clockwise rotation, possibly also involving rotational forces along the Z-axis, fractures the posterior column as well, post-traumatic kyphosis and progressive neurological symptoms due to spinal instability . ``
Chaece 骨折 为椎体水平撕裂性损伤。以往认为暴力来自沿着X轴旋转的力最大，使脊柱过伸而产生损伤，例如从高空仰面落下，着地时背部被物体阻挡，使脊柱过伸，前纵韧带断裂，椎体横形裂开，棘突互相挤压而断裂，可以发生上一节椎体向后移位。而目前亦有人认为是脊柱屈曲的后果，而屈曲轴则应在前纵韧带的前方，因此认为是脊柱受来自Y轴轴向牵拉的结果，同时还有沿着X轴旋转力量的参与，这种骨折也是不稳定性骨折。临床上比较少见； A Chaece fracture is a tearing injury at the level of the vertebral body. In the past, it was believed that violence comes from the greatest force of rotation along the X-axis, which causes the spine to hyperextend and cause damage. For example, falling from a high altitude on the back, the back is blocked by an object when landing, causing the spine to hyperextend, the anterior longitudinal ligament is broken, and the vertebral body is split horizontally. The spinous processes squeeze each other and break, and the previous vertebral body can be displaced backwards. At present, some people think that it is the result of spinal flexion, and the flexion axis should be in front of the anterior longitudinal ligament. Therefore, it is considered that the spine is pulled from the Y-axis axially, and at the same time, there is also the participation of rotational forces along the X-axis. This fracture is also an unstable fracture. clinically rare;
屈曲-牵拉型损伤屈曲轴在前纵韧带的后方，前柱部分因压缩力量而损伤，而中、后柱则因牵拉的张力力量而损伤，而中、后柱则因牵拉的张力力量损伤，中柱部分损伤表现为脊椎关节囊破裂，关节突脱位，半脱位或骨折，这种损伤往往还有来自Y轴旋转力量的参与，因此这类损伤往往是潜在性不稳定型骨折，原因是黄韧带，棘间韧带和棘上韧带都有撕裂。 In flexion-traction injuries, the flexion axis is behind the anterior longitudinal ligament, and the anterior column is damaged due to compressive forces, while the middle and posterior columns are damaged due to tensile forces, while the middle and posterior columns are damaged due to tensile forces. Injuries to the strength, part of the central column are manifested by rupture of the spinal joint capsule, dislocation of the articular process, subluxation or fracture. This kind of injury often involves the participation of force from the Y-axis rotation, so this type of injury is often a potentially unstable fracture. The cause was a tear in the ligamentum flavum, interspinous ligament, and supraspinous ligament. ``
脊柱骨折-脱位 又名移动性损伤。暴力来自Z轴，例如车祸时暴力直接来自背部后方的撞击，或弯腰工作时，重物高空坠落直接打击背部，在强大暴力作用下，椎管的对线对位已经完全破破坏，在损伤平面，椎沿横面产生移位，通常三个柱均毁于剪力，损伤平面通常通过椎间盘、同时还有旋转力量的参与，因此脱位程度重于骨折，当关节突完全脱位时，下关节突移至下一节脊椎骨上关节突的前方，互相阻挡，称关节突交锁，这类损伤极为严重的脊椎损伤难免，预后差。 另外还有一些单纯性附件骨折如椎板骨折与黄突骨折，不会沉重脊椎的不稳定，称为稳定型骨折，特别是横突骨折，往往是背部受到撞击后腰部肌肉猛烈收缩而产生的撕脱性骨折。Spinal fracture-dislocation is also known as mobility injury. Violence comes from the Z axis. For example, in a car accident, the violence directly comes from the impact on the back of the back, or when bending over to work, a heavy object falls from a high altitude and hits the back directly. Under the action of strong violence, the alignment of the spinal canal has been completely destroyed. In the plane, the vertebrae are displaced along the transverse plane. Usually, the three columns are destroyed by shear force. The plane of injury usually passes through the intervertebral disc, and at the same time, there is also the participation of rotational force. Therefore, the degree of dislocation is heavier than that of fracture. When the articular process is completely dislocated, the lower joint The articular process moves to the front of the upper facet process of the next vertebrae and blocks each other, which is called facet joint locking. This kind of extremely serious spinal injury is inevitable and the prognosis is poor. In addition, there are some simple appendage fractures, such as lamina fractures and luteal process fractures, which will not cause severe spinal instability. They are called stable fractures, especially transverse process fractures, which are often caused by the violent contraction of the lumbar muscles after the back is hit. Avulsion fracture.
脊柱骨折者从受伤现场运输至医院内的急救搬运方式至关重要，没有固定的情况下，通常一人抬头，一人抬脚或用搂抱的搬运方法十分危险，因这些方法会增加脊柱的弯曲，可以将碎骨片向后挤入椎管内，加重了脊髓的损伤，在没有固定装置的条件下，比较正确的方法是采用担架，木板甚至门板运送，先使伤员双下肢伸直，木板放在伤员一侧，三人用手将伤员平托至门板上，或二三人采用滚动法，使伤员保持平直状态，成一整体滚动至木板上。 治疗 有其他严重多发伤者，应优先治疗技术损伤，以挽救伤员生命为主。The first aid transport method for spinal fracture patients from the injury site to the hospital is very important. If there is no fixation, usually one person lifts the head, one person lifts the foot or the method of hugging is very dangerous, because these methods will increase the curvature of the spine and can Squeeze the bone fragments backward into the spinal canal, aggravating the injury of the spinal cord. In the absence of fixation devices, the more correct method is to use a stretcher, wooden boards or even door boards to transport the injured person. On the side of the wounded, three people use their hands to support the wounded flat to the door, or two or three people use the rolling method to keep the wounded in a straight state and roll them onto the wooden board as a whole. Treatment For those with other severe multiple injuries, priority should be given to the treatment of technical injuries, with the focus on saving the lives of the wounded.
脊柱内固定装置已经被广泛地应用于治疗胸腰椎骨折、脊柱肿瘤、脊柱畸形矫正和其他各种需要手术治疗的脊柱疾病的临床治疗。现有脊柱内固定装置大多为U形螺钉、固定杆和横连杆的组合，只能使用固定型号的装置来针对不同的治疗方案。没有可拆解性，不能快速适应人体条件，应用受到局限。Spinal internal fixation devices have been widely used in the clinical treatment of thoracolumbar fractures, spinal tumors, correction of spinal deformities, and various other spinal diseases that require surgical treatment. Most of the existing spinal internal fixation devices are a combination of U-shaped screws, fixation rods and transverse connecting rods, and only fixed types of devices can be used for different treatment plans. Without disassembly, it cannot quickly adapt to human conditions, and its application is limited.
