摘　　要：目的探索制作猪股骨头内动脉铸型标本的血管显示方法。方法于3例猪股骨头3根支持带动脉主干显微灌注环氧树脂大红色精混合液,凝固后进行碱腐蚀去除软组织,3D扫描股骨头轮廓并打印模具。酸腐蚀及冲洗股骨头至完全显露头内动脉。3D打印模具置于暴露血管的股骨头上并填充环氧树脂,凝固后去除模具并对股骨头表面进行抛光,制成显露股骨头内血管网的透明股骨头。结果环氧树脂大红色精混合液铸型剂灌注后酸碱腐蚀冲洗,成功制成了猪股骨头内动脉铸型标本。应用3D打印技术成功复原股骨头,并制成了显露股骨头内血管网的透明股骨头。结论显微灌注腐蚀法能成功制作股骨头动脉铸型标本,此标本为研究股骨头血液供应提供了形态学基础。3D打印填充技术成功建立了透明股骨头血管标本,能够较好的保留股骨头的轮廓及头内血管。Objective To explore the vascular display method of making cast specimens of internal femoral head artery in pigs.Methods The arterial trunks of three retinacular artery of pig femoral heads in 3 pigs were perfused with epoxy resin red essence mixture.After solidification,the soft tissues were removed by alkali corrosion.The femoral head contour was scanned in 3D and the mold was printed.Acid corroded and flushed the femoral head until the internal cephalic artery was completely exposed.The 3D printing die was placed on the femoral head exposed to blood vessels and filled with epoxy resin.After solidification,the die was removed and the surface of the femoral head was polished to make a transparent femoral head exposing the vascular network in the femoral head.Results Porcine femoral head internal artery casting specimen was successfully made by pouring epoxy resin red essence mixture casting agent and washing with acid and alkali corrosion.The femoral head was successfully restored by 3D printing technology,and a transparent femoral head was made to reveal the vascular network in the femoral head.Conclusions Micro-perfusion corrosion method can successfully make femoral head artery cast specimen,which provides morphological basis for studying femoral head blood supply.The transparent femoral head vascular specimen was successfully established by 3D printing filling technology,which can preserve the contour of femoral head and blood vessels in the head.
