摘　　要：目的针对大面积皮肤缺损,运用3D打印技术准确地进行游离皮片移植。方法利用3D扫描技术进行患肢建模,并构建皮肤缺损区域,利用树脂材料打印皮肤缺损处模型,术前进行供体区域取皮设计,保证供区取皮处无张力闭合;标记裁剪拼接点,按3D模型裁剪皮片后进行点对点拼接,覆盖创面表面进行创面植皮处理。结果利用3D打印技术进行术前取皮供区规划可更好地覆盖创面,供区可达到完全无张力缝合,手术时间极大降低,提高大面积不规则创面皮肤移植存活率。结论利用3D打印进行术前取皮规划,能提高手术效率,并极大降低供区损害,为大面积不规则皮肤缺损提供更好的个性化创面修复。Objective For large area skin defects,using 3D printing technology to perform free skin transplantation more accurately.Methods 3D scanning technology was used to model the affected limb,and the skin defect area was constructed.The skin defect model was printed with resin material.The skin removal design of the donor area was carried out before surgery to ensure that the skin removal area of the donor area was closed without tension.The cutting and splicing points were marked.After cutting the skin according to the 3D model,point-to-point splicing was carried out,and the wound surface was covered for wound skin grafting.Results 3D printing technology was used to plan the preoperative skin donor area,which better covered the wound,and the donor area was completely tension-free suture,greatly reducing the operation time,and improving the survival rate of skin transplantation on large irregular wounds.Conclusion The use of 3D printing for preoperative skin removal planning can improve the efficiency of surgery,greatly reduce the damage of the donor area,and provide better personalized wound repair for large-scale irregular skin defects.
