目的    制作“点赞”的前臂及手掌动脉铸型以及为其原型包埋，为临床诊治，解剖学的教学、科研及科普提供直观的血管原型包埋模型，为其他不同形态的铸型标本的原型包埋提供经验及依据。方法     以带造型手掌为模，以硅胶及石膏为材料，制作阴阳面硅胶包埋模具，然后把标本灌注，腐蚀，最后把铸型放进硅胶模具内，使用水晶AB胶浇注。  结果    水晶模型透明度高，无气泡，造型与设计一致，能够清晰地观察内部的血管铸型的管道走行及分布，清晰的观察到血管铸型与表皮及关节之间的空间比邻关系。  结论    制作成本低廉，性价比高；血管铸型真实、精细，本方法可体现血管在不同姿势下，与表皮及关节之间的空间比邻关系，为临床诊治，解剖学的教学、科研及科普提供直观的血管原型包埋模型，可为其他不同形态的铸型标本的原型包埋提供经验及依据。

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.
