Abstract: Objective To reconstruct the corresponding structures of the lumbar spine and to demonstrate virtual simulation of lumbar puncture using a three-dimensional visualization model,aiming to provide a new learning method for lumbar puncture and thus improve the learning outcomes. Methods By downloading the original enhanced CT tomography dataset of a whole abdomen provided by An Image Open Data Collection and post-processing it by using the open-source 3D Slicer software.The structures of the spinal cord,spinal arachnoid membrane,spinal dura mater,vertebra and other structures were sequentially reconstructed,a virtual simulation of lumbar puncture was performed with the help of the virtual puncture module. Results The visualization model of the lumbar spine was successfully reconstructed,we can adjust the color and transparency of the model can clearly display the lumbar spine and its adjacent structures.With the help of the virtual puncture module,virtual simulation puncture of lumbar puncture surgery can be performed,dynamically displaying the structure and adjacent relationships of the puncture needles in sequence. Conclusion By utilizing open-source 3D Slicer software,a visualization model of the lumbar spine can be reconstructed,and in combination with the virtual puncture technique,the relationship between the virtual puncture needle and the adjacent structures can be demonstrated,and the insertion position,angle,depth and optimal puncture path of the virtual simulation puncture needle can be dynamically displayed.aiming to provide a new means of learning lumbar puncture and thus improve the learning effect.The aim is to provide a new learning method for lumbar puncture surgery,thereby improving the learning effect.
