SENSIMMER? Virtual Phaco Trainer for Cataract Surgery

描述（由申请人提供）：ImmersiveTouch Inc.开发创新的增强虚拟现实软件SENSIMMER}，用于神经外科和眼科等领域的住院医师手术培训。该伙伴关系与芝加哥的伊利诺伊大学合作，提议开发白内障手术培训模块并使其商业化。在STTR I期和II期之后，SENSIMMER虚拟超乳培训器将包括用于白内障手术主要部分任务的五个模块：（1）透明角膜切口（2）囊破裂术，（3）超声乳化术，（4）软皮质材料去除和（5）眼内透镜植入物植入。到目前为止，我们在住院医师试验之前的最新科学突破是基于撕囊模块的复杂数学模型，其产生模拟前透镜囊的更真实和更少的过度弹性撕裂行为。作为STTR第I阶段任务的一部分，该项目的具体目标如下：a）改善前透镜囊的撕裂行为。现有的模型必须做得更没有弹性，更容易撕裂，就像一个典型的接受白内障手术的老年患者一样。将开发不同程度的模拟弹性以模拟人类透镜囊的弹性变化。B）手术器械插入和角膜切口处的枢轴点。当前模拟允许住院医师在接近前透镜囊时具有无限的操作空间和镊子角度，模拟“开放天空”方法。需要对角膜切口处的仪器的枢轴点进行建模，并且该问题的解决方案是重要的。c）前透镜囊的变形性。撕囊钳朝向前透镜囊的穿透深度目前无法由用户在撕裂之前容易地判断。需要对前囊进行实时变形建模，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。外科医生目前坐在虚拟超乳训练器前的姿势与在台式电脑前工作所需的姿势相同。该合作伙伴计划将头戴式显示器放置在固定框架上，以代表手术显微镜，并将触针直接放置在其下方，以更准确地代表外科医生在实际手术中的姿势。ImmersiveTouch Inc.已经就撕囊术和其他模块的潜在商业化进行了重要接触。以及眼保健行业的大公司，如Alcon Labs，它们可能会获得该技术的分销权。公共卫生相关：ImmersiveTouch Inc.开发创新的增强虚拟现实软件SENSIMMER}，用于神经外科和眼科等领域的住院医师手术培训。该伙伴关系与芝加哥的伊利诺伊大学合作，提议开发白内障手术培训模块并使其商业化。在STTR I期和II期之后，SENSIMMER虚拟超乳培训器将包括用于白内障手术主要部分任务的五个模块：（1）透明角膜切口（2）囊破裂术，（3）超声乳化术，（4）软皮质材料去除和（5）眼内透镜植入物植入。

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.
