项目摘要

Development and validation of a Virtual Colorectal Surgical Trainer (VCoST) Abstract For the first time in the history of surgery, a hands-on surgical technical skills examination – the Colorectal Objective Structured Assessment of Technical Skills (COSATS), developed by the American Society of Colon and Rectal Surgeons (ASCRS) – has been introduced in the American Board of Colon and Rectal Surgeons (ABCRS) examination, starting in 2014. The COSATS requires an elaborate setup with eight different stations through which residents must circulate to perform five open surgical tasks (rectal prolapse, pelvic bleeding, ileal pouch anal anastomosis, coloanal anastomosis, handsewn anastomosis), two laparoscopic and a colonoscopic task. It is anticipated that a computer generated virtual reality (VR)-based simulator with both visual and haptic (touch) feedback could provide an integrated training and evaluation environment for colorectal residents to climb their "learning curves" without risk to actual patients, standardize the process of skill training and credentialing and allow objective quantification of performance, without the need for human proctors. While VR simulation technology is being developed for colonoscopy and laparoscopic surgical procedures, three major technical hurdles have thwarted the development of VR-based simulation of open surgical procedures, such as the ones in COSATS: (1) fully immersive 3D visualization to allow surgeons to interact with the patient’s anatomy directly using their hands as well as manipulate untethered surgical tools; (2) high fidelity stable computations for contact detection, response and physical simulations; and (3) full-hand bi-manual haptic interactions with the virtual anatomy and untethered surgical tools. Our aim, in this present proposal, is to overcome these challenges and design, develop, and evaluate, for the first time, a Virtual Colorectal Surgical Trainer (VCoST) for the five open surgical tasks in the COSATS. To achieve our goal, a multidisciplinary research team has been assembled to achieve the following specific aims: (SA1) Develop a VCoST platform. Specifically, we will develop: (1) highly realistic simulation of the five open COSATS tasks within an immersive 3D high definition (HD) head mounted display (HMD) system; (2) physics-based simulations based on in vivo experimental studies; (3) novel haptic interface devices (with both tactile and force feedback) that allow realistic full-hand interactions with the virtual anatomy and untethered surgical tools; and (4) real time assessment and feedback. (SA2) Establish the validity of the VCoST as a training tool. We will conduct experiments on voluntarily enrolled subjects to establish face and construct validity of the VCoST. We hypothesize that the VCoST tasks, like the COSATS tasks, will be capable of distinguishing the skill levels of graduating general surgery and colorectal surgery residents.(SA3) Evaluate the usefulness of the VCoST as a training tool. We will perform learning, retention, and transfer-of-learning studies on the VCoST. We hypothesize that residents who trained with VCoST will demonstrate learning and transfer in the clinical environment, and will perform better than a control group.

虚拟结直肠手术训练器 (VCoST) 的开发和验证抽象的外科史上首次进行外科技术技能实操考试——结直肠技术技能客观结构化评估 (COSATS)，由美国社会科学协会开发结肠和直肠外科医生 (ASCRS) – 已被美国结肠和直肠委员会引入外科医生 (ABCRS) 考试，从 2014 年开始。 COSATS 需要精心设置，包括八个居民必须通过不同的站点进行检修才能执行五种开放式手术任务（直肠脱垂、盆腔出血、回肠贮袋肛管吻合术、结肠肛管吻合术、手缝吻合术），两个预计腹腔镜和结肠镜任务是由计算机生成的基于虚拟现实（VR）的任务。具有视觉和触觉（触摸）反馈的模拟器可以提供集成的培训和评估为结直肠居民攀爬“学习曲线”而不会给实际患者带来风险的环境，标准化技能培训和认证过程，并允许对绩效进行客观量化，而无需 VR 模拟技术正在开发用于结肠镜检查和检查。腹腔镜手术的三大技术障碍阻碍了基于VR的发展模拟开放式外科手术，例如 COSATS 中的手术：(1) 完全沉浸式 3D 可视化允许外科医生直接用手与患者的解剖结构进行互动以及操纵 (2) 接触检测、响应和物理的高保真稳定计算模拟；(3) 与虚拟解剖和不受束缚的手术的全手触觉交互在本提案中，我们的目标是克服这些挑战并设计、开发和使用。首次评估虚拟结直肠手术训练器 (VCoST) 的五种开放式手术任务为了实现我们的目标，COSATS 组建了一个多学科研究团队。具体目标如下： (SA1)开发一个高度VCoST的平台具体来说，我们将开发： (1)切合实际。在沉浸式 3D 高清 (HD) 头戴式显示器中模拟五个开放式 COSATS 任务（HMD）系统；（2）基于体内实验研究的物理模拟；（3）新颖的触觉界面允许与虚拟解剖结构进行真实的全手交互的设备（具有触觉和力反馈） (4) 实时评估和反馈（SA2）建立有效性。 VCoST 作为训练工具，我们将对自愿加入的受试者进行实验，以建立面孔和特征。我们发现 VCoST 任务（如 COSATS 任务）将能够实现。区分普通外科和结直肠外科住院医师的技能水平的差异。（SA3）评估 VCoST 作为培训工具的实用性我们将进行学习、保留和迁移学习。我们勇敢地说，接受过 VCoST 培训的居民将表现出学习和能力。转移到临床环境中，并且会比对照组表现更好。
