Hand anatomical model

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. The bones, ligaments, blood vessels, and nerves are full-color materials. Observe the internal anatomy through the transparent materials. The internal anatomical structure is consistent with the real specimen. Most of the blood vessels and nerves are in an empty state, retaining the true spatial positional relationship of these structures, and can truly express the morphological characteristics of normal hand blood vessels and nerves. The blood vessels and nerves of the anatomical specimen are directly attached to the surface of the adjacent muscles and tendons during the stroke, losing the true anatomical positional relationship. Data source Data sources: 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 basis for reference and comparison of the model.
