Hand blood vessels and nerves

"Digihuman Technology" builds a 3D digital anatomical model with multiple structures through high-precision digital human data, and extracts the voxels of the corresponding parts of the digital human data as We use a full-color, multi-material 3D printer and environmentally friendly colored resin materials to print high-simulation anatomical specimens. We use a full-color, multi-material 3D printer with environmentally friendly colored resin materials to print high-simulation anatomical specimens in order to provide 1:1 high-simulation physical anatomical models for the severely lacking cadaveric specimens.

Key words

Application Introduction

Introduction to Specimen

Material: transparent hard material                 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.
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.
