在麻醉解剖学及脊柱外科等解剖学实验课中,需要切开椎管。以往常用骨凿及手动椎板锯手工切开椎管,操作时劳动强度大,费时,费力,效率低。大规模教学中,由于时间紧,切开的椎管多,很难取得好的教学效果。我们研制了一个椎板锯,经两届麻醉解剖学实验教学使用,效果良好,现将其制作介 In anesthetic anatomy and spine surgery and other anatomical experimental class, need to cut the spinal canal. In the past commonly used bone chisel and manual vertebral saw manually cut the spinal canal, the operation of labor-intensive, time-consuming, laborious, inefficient. Large-scale teaching, due to tight time, cut the spinal canal and more difficult to achieve good teaching results. We developed a lamina saw, after two anesthesia anatomy experiment teaching, the effect is good, now its production media
