DESCRIPTION (provided by applicant): ImmersiveTouch Inc. develops innovative augmented virtual reality software SENSIMMER} for surgical training of residents in such fields as neurosurgery and ophthalmology. In collaboration with the University of Illinois at Chicago, the Partnership proposes to develop and commercialize its training modules for cataract surgery. Following STTR Phases I and II, the SENSIMMER Virtual Phaco Trainer will include five modules for the major part-tasks of cataract surgery: (1) Clear corneal incision (2) Capsulorrhexis, (3) Phacoemulsification, (4) Removal of soft cortex material and (5) Intraocular lens implant insertion. To date, our most recent scientific breakthrough prior to the residents' trial is a sophisticated mathematical model underlying the capsulorrhexis module, which produces a more realistic and less over-elastic tearing behavior of the simulated anterior lens capsule. The specific aims for this project as part of the STTR Phase I tasks are as follows: a) Refinements of the tearing behavior of the anterior lens capsule. The existing model must be made even less elastic and more prone to tear, as in a typical older patient who undergoes cataract surgery. Different degrees of simulated elasticity will be developed to simulate the variations in the elasticity of the human lens capsule. b) Surgical instrument insertion and pivot point at corneal incision. The current simulation allows the resident unlimited operating space and forceps angle in approaching the anterior lens capsule simulating an "open sky" approach. A pivot point for the instrument at the corneal incision needs to be modeled, and the solution to this problem is non-trivial. c) Deformability of anterior lens capsule. The depth of penetration of capsulorrhexis forceps towards the anterior lens capsule cannot currently be easily judged by users prior to tearing. Real-time deformability modeling for the anterior capsule is needed to provide a better depth perception. d) Surgeon operating posture and microscope simulation. Surgeons currently sit in front of the Virtual Phaco Trainer in the same posture as that needed to work at a desktop computer. The Partnership intends to place a head-mounted display on a fixed frame to represent an operating microscope, and to position the stylus directly beneath it to more accurately represent the surgeon's posture in actual surgery. Significant contacts for potential commercialization of the capsulorrhexis and other modules have already been made between ImmersiveTouch Inc. and much larger firms in the eye care industry, such as Alcon Labs, which may be granted distribution rights for the technology. PUBLIC HEALTH RELEVANCE: ImmersiveTouch Inc. develops innovative augmented virtual reality software SENSIMMER} for surgical training of residents in such fields as neurosurgery and ophthalmology.

描述（由申请人提供）：Immersivetouch Inc.开发创新的增强虚拟现实软件感官}，用于对神经外科和眼科诸如居民进行外科培训。与芝加哥伊利诺伊大学合作，该伙伴关系建议开发和商业化其白内障手术的培训模块。在STTR I和II阶段之后，感官虚拟Phaco培训师将包括五个用于白内障手术的主要部分的模块：（1）清晰的角膜切口（2）capsulorrhexis，（3）Phacoulsification，（3）（4）（4）（4）移除软皮层材料和（5）囊内植入植入植入植入式插入。迄今为止，我们在居民试验之前的最新科学突破是Capsulorrhexis模块基础的复杂数学模型，该模型产生了模拟前镜头胶囊的更现实且更少的过度弹性撕裂行为。作为STTR I期任务的一部分，该项目的具体目的如下：a）前镜头囊的撕裂行为的改进。必须使现有模型变得更少弹性，更容易撕裂，就像在接受白内障手术的典型老年患者中一样。将开发不同程度的模拟弹性，以模拟人透镜胶囊的弹性变化。 b）角膜切口处的手术仪器插入和枢轴点。当前的模拟使居民无限的操作空间和镊子角接近前镜头胶囊，以模拟“开放天空”方法。需要对角膜切口的仪器的一个枢轴点进行建模，并且解决此问题的解决方案是不平凡的。 c）前镜头囊的变形性。当前，用户在撕裂之前，用户很容易判断囊乳糖钳向前镜头囊的渗透深度。需要对前囊的实时可变形性建模，以提供更好的深度感知。 D）外科医生操作姿势和显微镜模拟。目前，外科医生坐在虚拟Phaco教练的前面，与在台式计算机上工作相同的姿势。该合作伙伴关系打算在固定框架上放置头部饰物显示，以代表操作显微镜，并将其直接放置在其下方的手写笔，以更准确地代表外科医生在实际手术中的姿势。在Immersivetouch Inc.与眼保健行业中的大型公司（例如Alcon Labs）之间，已经建立了有关囊糖和其他模块的潜在商业化的重要联系，例如ALCON LABS可以授予该技术的分销权。公共卫生相关性：Immersivetouch Inc.开发了创新的增强虚拟现实软件感知器}，以对神经外科和眼科等领域的居民进行手术培训。与芝加哥伊利诺伊大学合作，该伙伴关系建议开发和商业化其白内障手术的培训模块。在STTR I和II阶段之后，感官虚拟Phaco培训师将包括五个用于白内障手术的主要部分的模块：（1）清晰的角膜切口（2）capsulorrhexis，（3）Phacoulsification，（3）（4）（4）（4）移除软皮层材料和（5）囊内植入植入植入植入式插入。
