Material: soft and hard material
Data source: digital model of the human body
The lumbar intervertebral disc herniation model is a printed model that combines soft and hard materials. The shape and degree of disc protrusion are based on pathological data from real patients and formed by merging data. This model contains the normal anatomical structure of the lumbosacral region and various options for lumbar intervertebral disc herniation models.
The normal model includes the lumbar spine, sacrum, and associated intervertebral discs, ligaments, spinal nerves, dura mater of the spinal cord, cauda equina, etc.
Pathological symptoms of intervertebral disc herniation integrate morphological manifestations of central, lateral, and paracentral symptoms. This model can be used as a reference for planning and designing surgical treatment of intervertebral disc herniation, as well as an educational tool for explaining the condition to the patient.
Data sources
Data source: Selected data from high-precision digital anatomical images, including:
Original serial sections
Refined segmentation
3D geometric models of organs (bones, muscles, blood vessels, nerves, ligaments, etc.)
The voxel size of this dataset is 0.0384 mm × 0.0384 mm × 0.1 mm.
Formalin-fixed body preparations were also used as reference samples for 3D printing.
Modeling process
Voxels of each anatomical structure were extracted from the original tomographic dataset to create texture maps of the geometric model, ensuring that the appearance of each structure corresponds to the real anatomical sample.
