好的牙·讯|空军军医大学口腔医院近日宣布,其赵铱民院士团队自主研发的“自主式口腔多功能手术机器人”成功完成一例正颌外科手术。团队指出,经科技查新,这是国际范围内机器人首次自主完成正颌手术中的截骨与骨块定位任务。

据介绍,该手术针对一名长期受骨性下颌前突、面中部凹陷与偏颌困扰的患者实施。正颌手术中的LeFort I型截骨及上、下颌骨骨块再定位是核心步骤,要求对上颌骨进行毫米级精确截骨,并将带有上下颌牙列的骨块准确移动至规划位置。

手术团队由赵铱民院士、商洪涛教授、白石柱教授、田磊教授等多位专家共同参与会诊,制定治疗方案,并由机器人自主完成关键的截骨与骨块再定位环节。

团队在前期围绕机器人硬件体系、专用手术器械、规划平台与控制程序进行了多轮优化,并完成了动物实验与临床模拟测试,提升了机器人的安全性、精准度与稳定性。团队指出,机器人各项性能均满足正颌手术临床实际应用需求,有效解决了传统正颌手术中“精度依赖医生经验、手术操作风险较高”的临床难点。

手术前,团队基于患者CT及牙列扫描数据进行了三维虚拟手术规划,明确截骨平面与骨块目标位置。术中,机器人严格按预定方案执行,通过智能算法与高精度机械臂协同驱动骨动力末端执行器,沿规划路径完成上颌骨截骨,并将上、下颌游离骨块精准定位,实现了改善容貌外观与咬合功能的双重治疗目标。

团队表示,从种植手术、自体牙移植、根尖外科,到“颌骨缺损一日重建”,再到此次正颌手术的成功实施,标志着该机器人系统已初步具备在复杂解剖结构下应对各类高难度口腔颌面外科手术的能力。
