Objective    To make the forearm and palm artery cast with shape and to provide an intuitive vascular prototype embedding model for clinical diagnosis and treatment, anatomy teaching, scientific research and popular science, and to provide experience and basis for the prototype embedding of different forms of other cast specimens.   Methods    Using the palm of the hand as the mold and silica gel and gypsum as the material, the silicone embedding mold of Yin and Yang surface was made, and then the specimen was poured and corroded, and finally the mold was put into the silicone mold, and the crystal AB glue was used to cast.     Results    The crystal model has high transparency, no bubbles, consistent design. It allows for a clear observation of flow  and distribution of the internal blood vessel mold, as well as the spatial adjacency between the blood vessel mold and the skin and the joint.    Conclusions    The model is low production cost and high cost performance. The blood vessel casting is real and precise. This method can reflect the spatial proximity between blood vessels, epidermis and joints in different poses, provide an intuitive vascular prototype embedding model for clinical diagnosis and treatment, anatomy teaching, scientific research and popular science, and provide experience and basis for the prototype embedding of different forms of other cast specimens.
