目的探讨3D打印技术在辅助脊柱肿瘤手术中的应用。方法对22例脊柱肿瘤患者术前行CT扫描,收集数据进行三维模型重建,使用3D打印机制作出与实体1:1大小的病灶区域的脊柱模型,参考打印模型,制定手术方案、模拟手术操作、预处理内置物,指导治疗。结果 22例均手术成功,症状均较术前有改善。术中参照打印模型,做到了精确、完整的切除病灶区域。术后X线复查,可见内置物位置良好,未见松动、移位。结论使用3D打印技术能够直观、全面的显示脊柱病灶区域的解剖毗邻关系,术者能够提前熟悉病灶,术中可以精确、完整的切除肿瘤,避免重要血管、神经的损伤,预处理内置物材料,进而缩短手术时间,减少术中出血。
Objective To explore the application of 3D printing technique in the assistant spinal surgery. Methods Twenty-two cases of patients with spinal tumors underwent preoperative CT scan. The data were collected for 3D reconstruction. 3D models of the spine with focal lesions of 1: 1 in size were made using the 3D printer. The reference print model was established, the surgical plan was developed and the operation was simulated. Pretreatment of built-in, guide treatment. Results All the 22 cases were operated successfully, the symptoms were improved compared with that before operation. Intraoperative reference print model, to do a precise and complete removal of the lesion area. Postoperative X-ray review, we can see the location of good objects, no loose, shift. Conclusions The 3D printing technology can directly and completely display the anatomic adjacency of the spinal lesions. The surgeon can get familiar with the lesion in advance and can cut the tumor accurately and completely during the operation to avoid the important blood vessels and nerves, pretreatment of the internal material, Then shorten the operation time, reduce intraoperative bleeding.
