目的：通过尸体研究探索国产ROPA人工智能髋关节置换手术机器人系统辅助全髋关节置换术（THA）的精准性及安全性。方法：应用ROPA手术机器人系统对4具双下肢完整的成年尸体标本进行THA。对股骨颈截骨距、髋臼假体前倾角及外展角、髋臼窝底骨量、假体型号、联合偏心距、双下肢长度差异进行术前规划，并与术后实测值进行比较，计算术后实测值与术前规划的误差。结果：3具尸体行双侧THA,1具尸体行单侧THA。术中均未发生假体周围骨折及脱位等并发症。术中手术机器人系统均稳定运行。术后股骨颈截骨距与术前规划的误差为0～0.4 mm，髋臼假体前倾角与术前规划的误差为0°～4°，髋臼假体外展角与术前规划的误差为0.3°～3.9°，髋臼窝底骨量与术前规划的误差为0.1～0.8 mm。术中使用髋臼假体及股骨柄假体型号均与术前规划一致，准确率为100%(7/7)。术后联合偏心距与术前规划的误差为0～0.8 mm。术后双下肢长度差异均<5 mm，与术前规划的误差为0.2～1.6 mm。结论：国产ROPA人工智能髋关节置换手术机器人系统辅助THA具有良好的精准性和安全性。
Abstract：Objective: To evaluate the accuracy and safety of total hip arthroplasty(THA) assisted by a domestically developed, artificial intelligence(AI)-enabled robotic system(ROPA) in a cadaveric model. Methods: Four adult cadaveric specimens with intact lower limbs underwent THA performed with the ROPA robotic system. Preoperative planning targeted the following parameters: femoral neck resection distance, acetabular component anteversion and abduction, acetabular floor bone stock, implant sizes, combined offset, and limb length discrepancy. Postoperatively, measured values were compared with the preoperative plans to calculate the deviation for each parameter. Results: Three cadavers underwent bilateral THA, and one cadaver underwent unilateral THA. No intraoperative complications such as periprosthetic fracture or dislocation occurred. The robotic system operated stably throughout all procedures. Postoperative deviations from preoperative plans were as follows: femoral neck resection distance, 0 to 0.4 mm; acetabular component anteversion, 0° to 4°; acetabular component abduction, 0.3° to 3.9°; acetabular floor bone stock, 0.1 to 0.8 mm. The sizes of both acetabular and femoral stem implants used intraoperatively matched the preoperative plans exactly, yielding an accuracy rate of 100%(7/7). The deviation in combined offset was 0 to 0.8 mm. The postoperative limb length discrepancy was <5 mm in all specimens, with deviations from preoperative planning ranging from 0.2 to 1.6 mm. Conclusions: In this cadaveric study, THA assisted by the domestically developed ROPA AI-enabled robotic system demonstrated excellent accuracy and safety.
