天玑骨科机器人辅助经皮椎体成形术

Tianji orthopaedic robot assisted percutaneous vertebroplasty

[目的]介绍“天玑”骨科机器人辅助经皮椎体成形术的手术技术和初步临床效果。[方法]1例女性患者,58岁,摔伤致胸椎压缩性骨折(T_(12)),采用“天玑”骨科机器人行椎体成形术。采用C形臂x线机正侧位2D空间扫描采集:二维影像数据信息,机器人操作平台规划导针,导针置人并验证,骨水泥注入。记录手术时间、术中透视次数及剂量,并对术后影像结果进行分析。[结果]本例患者手术耗时55 min,术中进行1次C形臂X线机正侧位二维扫描,6次X线透视;出血量约为5ml,无任何手术并发症;术后第2 d可以下地行走;术后X线检查提示:骨水泥注入量及分布位置满意。[结论]国产“天玑”骨科机器人利用二维影像辅助椎体成形术是一种新的精准、微创的手术方案。

[Objective]To introduce the surgical technique and preliminary outcome of Tianji orthopaedic robot assisted percutaneous vertebroplasty(PVP).[Methods]A 58-year-old female who was suffered from thoracic vertebral compression fracture(T12)secondary to falling received Tianji orthopaedic robot assisted PVP.After the two-dimensional data collected by using the C-arm X-ray machine were imputed,the robot operation platform made a operation plan,then guided and verified the needle placement and bone cement injection.The operation time,fluoroscopy times and radial dose were recorded,and clinical and imaging consequences were analyzed.[Results]The operation was lasted for 55 minutes,with only once of two-dimensional scan with the C-arm X-ray machine and 6 times of X-ray fluoroscopy.The patients got about 5ml of intraoperative blood loss without any complications,and returned walking on the second day after operation.As imaging findings postoperatively,the amount and distribution of bone cement injected were satisfactory.[Conclusion]The domestic"Tianji"orthopedic robot using two-dimensional image data to assist PVP is a new accurate and minimally invasive surgical scheme.
