本发明涉及了腰椎后路植入技术领域，特别是涉及了一种腰椎后路零切迹融合器系统及其使用方法。The invention relates to the technical field of lumbar posterior implantation, in particular to a lumbar posterior zero-profile fusion device system and a method for using the same.
背景技术Background technique
脊椎由一个椎体、两个椎弓根、两个椎板、两个横突、四个关节突和一个棘突组成的骨结构、分颈椎骨、胸椎骨、腰椎骨、骶椎骨、尾椎骨。由于不良习惯或由于瞬间的不适当行为就会导致腰椎疾病。目前随着人们脊椎疾病的频繁发病，对脊椎的治疗手段越来越有针对性，当前腰椎融合手术是目前治疗腰椎疾病的主要手段，腰椎融合器作为腰椎椎间界面融合技术中重要的内置物起着越来越重要的作用。腰椎融合器一般分有应用于前路的融合器和应用于后路的融合器。由于腰椎前路可操作空间大，前路融合器应用风险相比后路融合器的小，目前前路融合器取得了良好的效果但需要二个手术切口，手术复杂，创伤大，风险高。为此，业内开发出了后路融合器，如中国实用新型CN203693843U公开了一种腰椎后路侧置椎间固定融合器，又如中国实用新型CN209316161U公开了零切迹腰椎后路融合器等等。The spine consists of one vertebral body, two pedicles, two lamina, two transverse processes, four articular processes and one spinous process, divided into cervical vertebrae, thoracic vertebrae, lumbar vertebrae, sacral vertebrae, and coccygeal vertebrae . Lumbar spine disease can be caused by bad habits or by momentary inappropriate behavior. At present, with the frequent occurrence of spinal diseases, the treatment methods for the spine are becoming more and more targeted. The current lumbar fusion surgery is the main method for the treatment of lumbar diseases. The lumbar fusion device is an important built-in object in the fusion technology of the lumbar intervertebral interface. play an increasingly important role. Lumbar fusion devices are generally divided into fusion devices used in the anterior approach and fusion devices used in the posterior approach. Due to the large operable space in the anterior approach of the lumbar spine, the risk of anterior fusion fusion is lower than that of posterior fusion fusion. At present, anterior fusion fusion has achieved good results but requires two surgical incisions. The operation is complicated, traumatic and risky. For this reason, the industry has developed a posterior fusion device, such as the Chinese utility model CN203693843U which discloses a lumbar posterior lateral intervertebral fixation fusion device, and the Chinese utility model CN209316161U which discloses a zero-notch lumbar posterior fusion device, etc. .
腰椎后路置入融合器手术过程是：椎管的横径约2.5厘米，里面有硬膜囊，两侧有神经根，在进行置入融合器时，先要把一侧的神经根、硬膜囊一起向对侧牵开才显露椎间盘，切除突出的椎间盘后再置入融合器，再者置入后的融合器的顶端(即所述融合器的前侧顶部)要比椎体后缘深2-4毫米左右。The operation process of inserting the fusion device in the posterior approach of the lumbar spine is as follows: the transverse diameter of the spinal canal is about 2.5 cm, there is a dural sac inside, and there are nerve roots on both sides. The intervertebral disc is exposed only when the membrane capsule is retracted to the opposite side. The intervertebral disc is resected and then the fusion cage is placed. Furthermore, the top of the fusion cage after placement (that is, the front top of the fusion cage) is larger than the posterior edge of the vertebral body. About 2-4mm deep.
现有技术的腰椎后路融合器(至少包括但不限于上述两个实用新型所公开的后路融合器)通过打入器置入椎体间的融合器之后，打入器撤出后，由于神经根、硬膜囊回位，覆盖或部分覆盖了融合器顶端，使得顶端几乎无法直接观察到，更无法在融合器顶端旋入锁定钉；目前现有的后路置入融合器在具体临床实践中是无法操作的，其原因是：把神经根和硬膜囊向对侧牵开只能到椎管中线，约1.3厘米左右，在这个宽度下置入宽为1厘米的融合器，为了旋入锁定钉需要二次牵开神经根、硬膜囊会造成神经根受到过度牵开或频繁牵开而损伤，以及旋入锁定钉极易造成对周围的神经根、硬膜囊等神经组织的磨损损伤，风险性很高。The posterior lumbar fusion device of the prior art (including but not limited to the posterior fusion device disclosed in the above two utility models) is inserted into the intervertebral fusion device through the driver, and after the driver is withdrawn, due to Nerve roots and dural sacs return, covering or partially covering the top of the fusion cage, making it almost impossible to directly observe the top of the fusion cage, let alone screw the locking nail on the top of the fusion cage; In practice, it is impossible to operate. The reason is that retracting the nerve root and dural sac to the opposite side can only reach the midline of the spinal canal, about 1.3 cm. Screwing in the locking screw requires secondary retraction of the nerve root, and the dural sac will cause damage to the nerve root due to excessive retraction or frequent retraction, and screwing in the locking screw can easily cause damage to the surrounding nerve roots, dural sac and other nerve tissues. The risk of wear damage is high.
即使如中国实用新型CN209316161U公开的融合器中采用了具有导向作用的锁紧孔的固定体，在实际后路置入椎体临床手术中，由于固定体是与融合器主体固定连接在一起置入椎体的，则置入后所述固定体顶端至少不超出椎体后缘，依然存在如上述无法直视到锁紧孔的情况，也即无法旋入锁定钉；即使在某些情况下可以牵开神经根、硬膜囊等神经组织，部分显露出融合器顶端以看到锁定孔，但也仅仅是看到锁定孔，而将一定长度的锁定钉倾斜一定角度经锁定孔旋入椎体过程中，不仅锁定孔外周面的螺纹存在接触损伤神经根、硬膜囊等神经组织的高风险，而且锁定钉是倾斜旋入相比垂直旋入需要将神经根、硬膜囊等神经组织牵开更大的操作空间这会造成更大的手术风险。Even if the fusion device disclosed in the Chinese utility model CN209316161U adopts a fixing body with a guiding locking hole, in the actual posterior vertebral body clinical operation, since the fixing body is fixedly connected with the main body of the fusion device and inserted together For the vertebral body, the top of the fixed body does not exceed the posterior edge of the vertebral body at least after it is placed, and there is still the situation that the locking hole cannot be seen directly as mentioned above, that is, the locking nail cannot be screwed in; even in some cases it can Nerve tissues such as the nerve root and dural sac are retracted to partially expose the top of the fusion cage to see the locking hole, but only the locking hole is seen, and a certain length of locking nail is screwed into the vertebral body through the locking hole at a certain angle. During the process, not only the thread on the outer peripheral surface of the locking hole has a high risk of contacting nerve roots, dural sac and other nerve tissues, but also the locking nail needs to pull the nerve roots, dural sac and other nerve tissues when it is screwed in obliquely compared with vertical screwing. Opening a larger operating space will cause greater surgical risks.
虽然现有已有零切迹腰椎后路融合器，但由于腰椎后路结构复杂，可操作空间小，具体应用时当前的零切迹腰椎后路融合器的可操作性不高，需要多次牵开神经根、硬膜囊等神经组织以及锁紧钉倾斜旋入过程存在损伤神经根、硬膜囊等神经组织的较大风险，故现有零切迹腰椎后路融合器真正应用于临床手术还是有很大的挑战性和手术风险。Although there are existing zero-profile posterior lumbar fusion devices, due to the complex structure of the posterior lumbar spine and the small operable space, the current zero-profile posterior lumbar fusion devices are not very operable in specific applications and need to be performed multiple times. There is a greater risk of damage to nerve roots, dural sac and other nerve tissues during the retraction of nerve roots and dural sac and the oblique screwing of locking screws. Therefore, the existing zero-profile posterior lumbar fusion device is really used in clinical practice. Surgery still has great challenges and surgical risks.

本发明具有如下有益效果：The present invention has following beneficial effect:
本发明将与融合器可拆卸连接的连接座的轴向高度为1.5cm以上，以及在连接座内设置有至少两条倾斜贯穿的通道，每一所述通道的出口端与一所述锁定孔相对应；所述通道轴线与所述连接座轴线之间的夹角为30～35°。如此设计，在完成腰椎后路椎管减压、椎间盘切除手术后，把相互连接的融合器和连接座，经过椎管由后向前置入椎体间，再用弹性螺丝批把所需长度的锁定钉插入所述通道并从锁定孔旋出进入椎体内，以将锁定钉锁定于所述融合器的前侧和椎体内完成所述融合器与所述椎体的锁定，最后移走所述打入器时连同移走连接座。According to the present invention, the axial height of the connecting seat detachably connected with the fusion device is more than 1.5 cm, and at least two obliquely penetrating channels are arranged in the connecting seat, and the outlet end of each channel is connected with one of the locking holes. Correspondingly; the included angle between the channel axis and the connecting seat axis is 30-35°. With this design, after completing the decompression of the lumbar posterior spinal canal and intervertebral disc resection, the interconnected fusion device and connecting seat are inserted into the intervertebral body from the back to the front through the spinal canal, and then the required length is adjusted by an elastic screwdriver. The locking nail is inserted into the channel and screwed out from the locking hole into the vertebral body, so as to lock the locking nail on the front side of the fusion device and the vertebral body to complete the locking of the fusion device and the vertebral body, and finally move When walking the driver, remove the connecting seat together.

Choose a locking nail with a suitable length, insert it into an inclined channel in the connecting seat, enter the locking hole and screw it into the vertebral body, so that the axial height of the connecting seat is more than 1.5cm, plus the axis of the channel and the connecting seat The angle between the axes is 30-35°, the entrance of the inclined channel is completely higher than the nerve roots, dural sac and other nerve tissues, and the inclined channel acts as a conduit, so that the nerve tissue outside the fusion cage and around the connecting seat Protected, during the process of screwing in the locking screw, the locking screw and the screwdriver are completely carried out on the connecting seat and fusion cage, without contact with the surrounding nerve tissue, so as to avoid or even eliminate the damage to the vertebral body during the screwing in of the locking screw accidents in the peripheral nerve tissue, and at the same time, the application of the lumbar posterior zero-notch fusion device system of the present invention only requires one posterior spinal canal incision, and does not need to make another anterior spinal canal incision, which can greatly reduce surgical costs, surgical risks, Surgical trauma and operation time have better social and economic benefits.
本发明连接座内设置的倾斜通道，不仅用于容纳限定整个或大部分的锁定钉和螺丝批进出路径以避免现有融合器仅在头部开设导入孔造成锁定钉开始旋入时出现晃动和偏离预设倾斜角度的问题，还将通道轴线与所述连接座轴线之间的夹角为30～35°使得通道的长度足够长可容纳不同长度锁定钉，便于根据椎体情况选择合适长度的锁定钉进一步提高融合器与两侧椎体的锁定稳定性，解决了现有内藏锁定钉的融合器置入椎体间后无法灵活调整锁定钉长度的问题。The inclined channel provided in the connecting seat of the present invention is not only used to accommodate and limit the entire or most of the locking nails and the screwdriver access path to avoid shaking and swaying when the locking nails start to be screwed in because the existing cage only has an introduction hole in the head. For the problem of deviating from the preset inclination angle, the included angle between the axis of the channel and the axis of the connecting seat is 30-35° so that the length of the channel is long enough to accommodate locking nails of different lengths, which is convenient for selecting the appropriate length according to the vertebral body condition. The locking nail further improves the locking stability between the fusion cage and the vertebral bodies on both sides, and solves the problem that the length of the locking nail cannot be flexibly adjusted after the fusion cage with built-in locking nails is placed between the vertebral bodies.
