摘　　要：目的探讨自主研发的智能骨科机器人辅助股骨髓内钉远端锁定的优势与效果。方法将32个成人尸体股骨标本随机分为两组,每组16个。实验组采用智能骨科机器人辅助股骨髓内钉远端锁孔锁定,对照组采用传统X线透视下手工锁定方法。记录并比较两组锁定时间、透视次数及首次锁定成功率。结果实验组锁定时间为(273.94±38.67)s,明显短于对照组的(378.38±152.72)s;透视次数为(4.56±0.81)次,明显少于对照组的(8.00±3.98)次;差异均有统计学意义[MD=73.054(−37.187,85.813),P=0.049;MD=1.969(−1.437,2.563),P=0.002]。实验组首次锁定成功率为100%(16/16),明显高于对照组68.75%(11/16),差异有统计学意义(P=0.043)。结论与传统透视下手工锁定相比,智能骨科机器人辅助股骨髓内钉远端锁定可以明显减少锁定时间及术中辐射,提高锁定成功率。Objective To explore the advantages and effectiveness of the independently developed intelligent orthopedic robot-assisted distal locking of femoral intramedullary nails.Methods Thirty-two adult cadaveric femur specimens were randomly divided into two groups,with 16 specimens in each group.The experimental group used the intelligent orthopedic robot to assist in the distal locking of femoral intramedullary nail holes,while the control group used the traditional method of manual locking under X-ray fluoroscopy.The locking time,fluoroscopy times,and the success rate of first locking were recorded and compared between the two groups.Results The locking time of the experimental group was(273.94±38.67)seconds,which was shorter than that of the control group[(378.38±152.72)seconds],and number of fluoroscopies was(4.56±0.81)times,which was less than that of the control group[(8.00±3.98)times].The differences were significant[MD=73.054(−37.187,85.813),P=0.049;MD=1.969(−1.437,2.563),P=0.002].The first locking success rate of the experimental group was 100%(16/16),which was significantly higher than that of the control group(68.75%,11/16)(P=0.043).Conclusion The efficiency of distal locking of femoral intramedullary nails assisted by the intelligent orthopedic robot is significantly higher than that of the traditional manual locking method under fluoroscopy,as it can markedly reduce the time required for distal locking of femoral intramedullary nails,decrease intraoperative radiation exposure,and increase the success rate of locking.
