 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）：本研究的目标是开发、探索其有效性并实施动态触觉机器人训练（DHRT）的新颖训练方法。该方法利用市售的触觉机器人，该机器人可以通过编程来施加力。我们假设这种培训方法将使住院医师能够更有效地培养他们的技能，在更短的时间内提高熟练程度，并更好地确保住院医师在达到熟练的技能水平之前。该目标将通过完成三个具体目标来实现：开发精确的针插入模型并实施到触觉机器人设备中。进行表征针插入软组织时的力的噪声。该信息将形成针插入模型，该模型将被编程到触觉机器人设备中，以模拟针插入的触觉感觉。该模拟器将由血管外科医生进行评估。进而进行相应修改，以确保针插入模拟的准确性。 具体目标 2：开发和优化动态触觉机器人训练 (DHRT) 程序假设 (H1) 我们发现，我们的 DHRT 程序将比传统 CVC 模拟器更好地提高 CVC 插入能力和成功率，因为它允许成功执行 CVC 程序所需的复杂认知和运动的发展，目标 1 中获取的针力数据将与人体解剖结构的新型视觉模拟心理相结合。 （例如血管壁位置、尺寸变化和壁厚）在图形用户界面中提供触觉和视觉反馈 DHRT 计划将通过将 DHRT 计划纳入好时医疗中心的教育课程进行实验测试。 假设 (H2)：动态触觉机器人培训计划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，以及与目前最先进的基于模型的培训方法相比，可以对住院医师 CVC 技能进行更准确的评估。为了验证这一假设，将在接受传统模型培训（第一年）的住院医师和接受传统模型培训的住院医师之间进行比较 CVC 并发症率和住院医师信心。 DHRT 培训方法（第二年）。
