PROJECT SUMMARY 1 A 2009 study found that 4 out of 5 surgical residents extended their training beyond residency because they 2 did not feel adequately trained to practice independently[1]. Medical program directors identified 121 surgical 3 procedures that they considered essential to a surgeon’s training[1]. However, 31 of these procedures (about 4 25% of all essential procedures) were found on average to be performed less than once by residents before 5 completion of residency[1]. Traditional forms of surgical training, such as the use of cadavers or medical 6 manikins, lack the fluid dynamic response to incisions, may not have identical anatomy (e.g. porcine), and may 7 be difficult to procure. In addition, opportunities to perform actual surgeries are very limited. Medical schools 8 have begun utilizing VR surgery simulation software, such as Touch Surgery, which can realistically simulate 9 the human body but lacks the hands-on aspect of a real operation. VR surgery simulation technology has been 10 shown to have a transfer-effectiveness ratio (TER) of 2.28 or, in other words, for every minute spent using VR 11 training an equivalent of 2.28 minutes using traditional training was saved[8]. Despite these benefits, however, 12 current VR training methods have a serious limitation: the software user must interact through a tablet or 13 joystick and does not hold the surgical tools or receive tactile feedback, which diminishes the skill’s transfer 14 effectiveness. As part of a previous research project, Lynntech developed an electromechanical device that 15 uses biomimetic artificial muscle fibers to move muscle-damaged fingers. We propose to transform this device 16 into a hand-worn peripheral to provide residents with the hand-tool interactions needed to realistically simulate 17 a surgery. In this way, the user will be able to hold, rotate, and move objects during the simulated surgery and 18 therefore practice movements needed in an actual surgery without the bulky or restrictive gloves now available. 19 The goal is to develop the VR Grip to increase the TER through more realistic training, leading to fewer 20 complications in actual surgeries. The following aims will be achieved: (1) develop the VR Grip glove, (2) 21 demonstrate that it can be tracked as it moves, (3) demonstrate that it can stop finger movements when 22 encountering virtual objects, and (4) develop the complete workstation. The final product is expected to be a 23 complete workstation that includes a VR headset, the VR Grip glove, a connected computer, interface 24 software, and a VR simulated environment with pre-programmed virtual objects such as scalpels. 25 This application for an Administrative Supplement is to purchase equipment that will allow Lynntech to 26 simulate human testing by measuring force responses to finger actuation. This will provide a significant 27 improvement on measuring the effectiveness of the VR Grip without the need for human testing in Phase I. In 28 this Administrative Supplement application, we are requesting monies for equipment and labor to install and 29 setup.

项目摘要 1一项2009年的研究发现，5个手术居民中有4个将他们的培训扩展到了居住之外 2没有受过适当的训练可以独立练习[1]。医疗计划主管确定了121个手术 他们认为对外科医生的训练至关重要的3个程序[1]。但是，其中31个程序（关于 4 25％的所有基本程序）平均发现居民的执行少于一次 5居住[1]。传统的手术培训形式，例如使用尸体或医疗 6 Manikins缺乏对切口的流体动态反应，可能没有相同的解剖结构（例如猪），并且可以 7很难采购。此外，进行实际手术的机会非常有限。医学院 8已开始使用VR手术模拟软件，例如触摸手术，可以实际模拟该软件 9人体，但缺乏真实手术的动手方面。 VR手术模拟技术已经 10显示的转移效应比（TER）为2.28，换句话说，每分钟使用VR 11训练使用传统培训相当于2.28分钟[8]。尽管有这些好处，但是 12当前的VR培训方法有一个严重的限制：软件用户必须通过平板电脑进行交互或 13操纵杆，不使用外科手术工具或接收触觉反馈，从而减少了技能的转移 14有效性。作为先前研究项目的一部分，Lynntech开发了一种机电设备 15使用仿生人造肌肉纤维移动肌肉损伤的手指。我们建议转换此设备 16进入手动的外围，为居民提供现实模拟所需的手工互动 17手术。通过这种方式，用户将能够在模拟手术和 18因此，在实际手术中需要进行练习运动，而现在没有笨重或限制性手套。 19目标是通过更现实的培训来开发VR抓地力，以增加TER，从而减少 实际手术中的20个并发症。将实现以下目标：（1）开发VR握把手套，（2） 21证明它可以随着移动而进行跟踪，（3）证明它可以在 22遇到虚拟对象，（4）开发完整的工作站。最终产品预计将是 23完整的工作站，包括VR耳机，VR握把手套，连接的计算机，接口 24软件和带有预编程的虚拟对象（例如手术刀）的VR模拟环境。 25此类管理补充申请是购买将允许Lynntech的设备 26通过测量对手指作用的力反应来模拟人类测试。这将提供重要的 27在不需要在I期中进行人体测试的无需人工测试的VR抓地力的有效性方面的提高。 28本行政补充申请，我们要求纳税设备和劳动力安装和 29设置。
