“E骨”-反肩置换术一站式术前规划系统

目的为提高反肩置换术术前规划的精准度和效率,本研究开发了“E骨”—反肩置换术一站式术前规划系统。方法利用nnU-net深度神经网络进行肩胛骨分割,获得精确的肩胛骨分割结果;结合骨密度、上下倾角和入钉长度3个关键因素自动定位基座,并计算出手术规划所需定量参数;结合关节盂形态和基座定位信息生成个性化导板;编写系统界面,将各部分功能模块化组装便于使用,提供交互操作与规划结果显示的功能。结果构建出“E骨”术前规划系统。本系统与Mimics系统相比,减少了规划过程中繁琐的手动调整,平均入钉长度规划结果长于Mimics系统,且规划时间缩短86%。本系统肩胛骨分割精度达到99.93%,较Mimics更高。结论本研究为反肩置换术提供了一套一站式的高效、精准的术前规划方案,具有广泛的临床应用前景。

术前辅助规划系统设计与实现

为帮助临床医生根据多个视角观察的病灶部位特征来拟定手术方案,本文开发设计了一种基于STL模型的术前辅助规划系统。系统采用C++和OpenGL技术构建,导入三维STL模型和三维渲染技术,具备精确地测量距离和角度等功能。实践结果表明,系统能够以三维的形式,从多个视角展示STL模型,包括视图的缩放、平行投影、反向、联动、同步、前后左右俯仰视图和自动旋转三维视图动画等。

人工智能三维规划辅助全膝关节置换术的研究

旨在探讨人工智能术前规划系统(AIKNEE system)辅助人工膝关节置换术(total knee arthroplasty,TKA)治疗终末期的膝关节骨性关节炎(knee osteoarthritis,KOA)患者的价值。方法 共纳入从2020年6月到2021年7月我院收治的24例(28膝)终末期(K-L 3-4期) KOA的病例。所有病例均采用AIKNEE系统进行术前规划,预估假体型号及截骨角度。记录实际应用假体型号与AI规划的匹配度,比较手术前后冠状面髋膝踝(hip-knee-ankle,HKA)角的偏移值,评价并记录患肢康复情况及并发症。结果 术后股骨假体与胫骨假体与术前规划的匹配率分别为85.71%和96.42%,整体匹配率达91.06%;所有病例下肢力线恢复良好;术后HSS(hospital for special surgery knee score,HSS)评分显示膝关节功能明显改善。对患者进行术后1个月随访,均未见并发症。结论 基于人工智能深度学习技术的三维规划系统(AIKNEE system)可以准确、高效地预测假体型号和假体摆放位置,效果稳定可靠,患者早期疗效满意。

Department of the Ministry of Higher non-art large-scale theatrical show themes and pre-planning studies

Gala is the creation of a complex system of project, planning is one of the important aspect of its creation. Party theme is clear, determination of content, the party structure, artistic, rendering of the program, the cast, in planning sessions are established. In the process of planning, we need use star advantage of media expansion strategy, and rely on government agencies, planning strategies such as beauty handsome effect to complete; system restructuring, backward thinking, and innovative methods such as the application of new technologies to accomplish the party＇s breakthrough innovation. But no matter what strategy is used, how, in the planning of cultural show, Planner is always the first factor, if there is no ＂planer＂ to participate in; party planning will be a problem. It is the use of planning methods and people are taking advantage of the above strategies, using the right kind of htunan way at the same time that complete party planning.
