基于平面标定和体表定位的双目导航技术在盆底手术中的应用研究
Application research of binocular navigation technology based on planar calibration and surface localization in pelvic floor surgery
摘要
Abstract
Objective To explore a technique based on planar calibration and surface localization to overcome the prob-lem of spatial registration of semi rigid body structure surface drift,in order to lay an important research foundation for achieving surgical navigation of pelvic floor semi rigid body structure.Methods The study was conducted at Chongqing health center for women and children form April to June 2024.The planar calibration method was used to verify the spatial registration accuracy of the target(simulated surgical instrument),and the changes in the surface markers after breathing and movement were collected through the semi rigid pelvic body surface markers of volunteers.The Loss function and re-spiratory compensation algorithm were used for spatial alignment to correct the drift error of the surface markers corre-sponding to the rigid pelvis.Results The planar calibration positioning method was stable with an accuracy of up to 0.02mm.After spatial registration calculation and correction through mathematical models,the drift error range of the left anterior superior iliac spine of the semi rigid pelvic structure was(0.69±0.01)mm(P＜0.05),the range of the right anteri-or superior iliac spine was(0.61±0.14)mm(P＜0.05),the range of the pubic symphysis was(0.90±0.16)mm(P＜0.05),and the stability of the navel was poor,with an error range of(1.34±0.37)mm(P＞0.05).Conclusion The technique based on plane calibration and surface localization methods can overcome the problem of surface drift in the semi rigid pelvic region,thus breaking through the bottleneck of the application of surgical navigation in binocular vision technology in semi rigid structures.关键词
