华西智能化腔镜技能训练及考核系统的构建

The Development of Huaxi Intelligent Endoscopic Skill Training and Assessment System

目的研究和开发一种智能化的腔镜技能训练及考核系统。方法通过全面系统地从视野定位、抓持、传递、裁剪、缝合打结共5个基本技能模块进行设计,运用图像识别、精细化感知等技术,使考量指标客观量化,并能自动采集量化数据,综合各方面量化指标进行智能评分。结果视野定位、抓持、传递、裁剪和缝合五个模块的系统准确识别率分别为90%、95%、99%、90%、89%,系统反应与处理时间分别为8~10s、<1s、<1s、1~3s、<1s。结论华西智能化腔镜训练及考核系统初步实现了腔镜技能的客观标准化、自动化和智能化评估,可为外科医师腔镜技能训练、技术准入考试提供了可靠的工具。

Objective To develop a novel objective standardized endoscopic skill training and assessment system based on artificial intelligence technology. Methods By designing five basic skill parts of endoscopic operation including vision location, clamping, delivering, shearing and suturing, we achieved objective standardized indexes which gained automatically with image recognition and refined perception. Results With Huaxi intelligent endoscopic skill training system, the accurate rates of vision location, clamping, delivering, shearing and suturing were 90%,95 %0,99%,90%, and 89% ,respectively. The response and performance time were 8-10 s,〈1 s, 〈1 s, 1-3 s, and 〈1 s, respectively. Conclusion Huaxi intelligent endoscopic skill training and assessment system has preliminarily possessed the capability to assess the endoscopic skills of surgeons objectively.
