Hand anatomical model

for teachingresinwith musculature

Constructing a multi-structured 3D digital anatomical model from high-precision digitized human body data. Full-color, multi-material 3D printer and environmentally friendly resin material printing, providing 1:1 high simulation of physical anatomical models. Data Source: Digital Human Model The 3D printed model of hand blood vessels and nerves is a transparent package model. The skin, superficial fascia, deep fascia, and other structures are all transparent materials, and the bones, ligaments, blood vessels, nerves, and muscles are full-color materials. Observe the internal anatomy through the transparent materials. The internal anatomical structure is consistent with the real specimen, and the transparent wrapping material maintains the spatial positional relationship of the anatomical structure, and can truly express the morphological characteristics of normal hand blood vessels, nerves, and muscles Data Source Data were selected from a high-precision digital human dataset, including raw tomographic data, refined segmentation data and 3D geometric models of organ structures, including bone, muscle, blood vessels, nerves, ligaments, and other anatomical structures, and the voxel size of this example dataset was 0.0384mm*0.0384mm*0.1mm. Also, cadaveric specimens fixed by formalin were selected as a 3D printing the basis for reference and comparison of the model. Modeling: The voxels of each anatomical structure surface were extracted from the original tomographic dataset to generate texture maps of the geometric model to ensure that the appearance of the geometric model of each anatomical structure has the same visual perception as that of the real anatomical specimen
