 DESCRIPTION (provided by applicant): The goal of this study is to develop, explore the effectiveness, and implement the novel training method of dynamic haptic robotic training (DHRT). This method utilizes a commercially available haptic robot that can be programed to apply forces to the resident's hand to mimic an actual needle insertion. We postulate this training method will allow residents to more efficiently build their skills, obtain greater proficincy in less time and will better ensure that a proficient skill level is reached before the residents ae allowed to perform these interventions on patients. This proposed goal will be accomplished through the completion of the three specific aims. Specific Aim 1: Develop accurate needle insertion model and implement into haptic robotic device. In this aim ex vivo bovine liver experiments will be conducted to characterize the noise in the force upon needle insertion into soft tissue. This information will form a needle insertion model that will be programed into a haptic robotic device to simulate the haptic feel of needle insertion. This simulator will be evaluated by expert vascular surgeons and then modified accordingly to ensure accuracy in needle insertion simulation. Specific Aim 2: Develop and Optimize the Dynamic Haptic Robotic Training (DHRT) Program Hypothesis (H1) We hypothesize that our DHRT program will improve CVC insertion competence and success rates better than traditional CVC simulators because it allows for the development of the complex cognitive and psychomotor needed to successfully perform CVC procedures. The needle force data acquired in Aim 1 will be integrated with novel visual simulations of human anatomical configurations (e.g. vessel wall location, size variation, and wall thickness) in a graphical user interface that will provide both haptic and visual feedback to surgeons. The DHRT program will be experimentally tested by quantitatively and qualitatively comparing the program method to the baseline static simulation models currently used Specific Aim 3: Assess long-term improvements in CVC insertions and patient safety after incorporation of the DHRT program in the educational curricula at Hershey Medical Center Hypothesis (H2): A dynamic haptic robotic training program can reduce complications rates among patients undergoing CVC procedures at Hershey Medical Center (HMC), improve confidence, and offer a more accurate assessment of resident CVC skills than current state of the art phantom based training methods alone. To validate this hypothesis CVC complication rates and resident confidence will be compared among residents who receive the traditional phantom training (Year 1) and residents who receive the DHRT training method (Year 2).

 描述（由申请人提供）： 本研究的目的是发展、探索和实施动态触觉机器人训练（DHRT）这一新的训练方法。这种方法利用了一个商业上可用的触觉机器人，可以编程施加力到居民的手，模仿实际的针插入。我们假设这种培训方法将使居民更有效地建立自己的技能，获得更大的proficincy在更短的时间，并将更好地确保熟练的技能水平达到之前，居民ae允许对患者进行这些干预。这一拟议目标将通过完成三个具体目标来实现。具体目标1：开发准确的针插入模型并在触觉机器人设备中实现。为此，将进行离体牛肝实验，以表征针插入软组织时力的噪声。该信息将形成针插入模型，该针插入模型将被编程到触觉机器人装置中以模拟针插入的触觉感觉。该模拟器将由血管外科专家进行评估，然后进行相应修改，以确保针插入模拟的准确性。具体目标二：开发和优化动态触觉机器人训练（DHRT）程序假设（H1）我们假设我们的DHRT程序将比传统的CVC模拟器更好地提高CVC插入能力和成功率，因为它允许开发成功执行CVC程序所需的复杂认知和心理学。目标1中采集的针力数据将与图形用户界面中的人体解剖结构（例如血管壁位置、尺寸变化和壁厚）的新型视觉模拟相结合，该界面将提供触觉和视觉反馈 给外科医生将通过定量和定性比较程序方法与当前使用的基线静态模拟模型，对DHRT程序进行实验测试。具体目标3：评估将DHRT程序纳入好时医疗中心教育课程后CVC插入和患者安全性的长期改善假设（H2）：一种动态触觉机器人训练程序可以降低在好时医疗中心（HMC）接受CVC手术的患者的并发症发生率，提高信心，并且提供比当前技术水平的单独的基于体模的训练方法更准确的住院CVC技能评估。为了验证这一假设，将比较接受传统体模培训（第1年）和接受DHRT培训方法（第2年）的住院医师之间的CVC并发症发生率和住院医师信心。
