项目摘要
DESCRIPTION (provided by applicant): The SENSIMMER" Virtual Phaco Trainer for Cataract Surgery is a hardware and software solution aimed at a worldwide market of ophthalmology residency programs (including 118 programs in the US). It is developed by the US small business concern ImmersiveTouch-Sensimmer Inc. (Westmont, IL), in collaboration with the surgery simulation team at the University of Illinois at Chicago (UIC) under PI Prof. Pat Banerjee, president of ImmersiveTouch-Sensimmer. The virtual trainer supports the teaching of cataract surgery by phacoemulsification ("phaco"). Phase I produced a prototype capsulorhexis trainer, now being perfected under an NEI-ARRA supplement. Phase II proposes to create a phacoemulsification trainer and to validate both trainers. Task 1. Validate post-ARRA Phase I capsulorhexis simulator. Validation was not funded in Phase I. Validation aims at showing face, construct, and concurrent validity of capsulorhexis. The scoring system of the capsulorhexis simulator includes the number of separate forceps grabs of the lens capsule membrane during capsulorhexis, the number of hits of the lens with the forceps, and the total time for the capsulorhexis. Qualitative factors such as optimal size and shape of the capsular tear and avoidance of errors such as radial tear, corneal incision stress, and corneal touches have recently been added. A system for scoring live operative performance and relating this to simulator performance still needs to be devised and validated. Task 2. Develop a Phase II capsulorhexis simulator. The Phase I simulator aims to simulate only a single standard case of capsulorhexis for verification. Commercialization will require a Phase II capsulorhexis simulator for individual patient variations. Patient variations can affect the visibility or accessibility of the anterior capsule and the rhexis edge (corneal opacity, vitreous opacity, deep set eye, anterior chamber depth, cortical cataract) as well as the mechanical stability or material properties of the eye and lens capsule (involuntary eye movement, posterior synechia = iris attached to lens, weak zonules, high vitreous pressure, capsular thickness and fragility in young vs. old, calcified plaque on anterior capsule). Task 3. Develop a phacoemulsification simulator. The trainee uses both hands and both feet: right hand = phaco handpiece; left hand = nucleus manipulator; right foot = phaco pedal; left foot = microscope adjustment. Real foot pedals (e.g., Alcon) will be used, and the phaco foot pedal will control three modes of the virtual phaco tip: (1) irrigation; (2) irrigation + aspiration; (3) irrigation + aspiration + ultrasound power. The SENSIMMER will simulate the phaco tip in virtual reality and model the instrument handle by the handle of the SensAble Phantom Omni haptic robot. The trainer will be capable of simulating standard surgical techniques (e.g., phaco chop; divide and conquer) and unusual clinical cases (e.g., weak zonules). The trainee will learn to control the rate of both fluid flow and ultrasonic power. Task 4. Validate the phacoemulsification simulator. Validation will again aim at demonstrating face, construct, and concurrent validity, as defined above. This will require developing scoring systems for both simulated and live phacoemulsification. The scoring system for simulated phacoemulsification will include factors such as total time for the operation, efficiency of instrument tip handling as measured by total tip path length, and appropriate use of phaco power settings to avoid thermal damage to the cornea.
PUBLIC HEALTH RELEVANCE: ImmersiveTouch-Sensimmer, 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 well developed modules for the two most difficult part-tasks of cataract surgery: capsulorrhexis and phacoemulsification.
描述(由申请人提供):SENSIMMER”白内障手术虚拟超乳培训器是一种硬件和软件解决方案,针对全球眼科住院医师项目市场(包括美国的118个项目)。它由美国小企业ImmersiveTouch-Sensimmer Inc.开发。(韦斯特蒙,伊利诺伊州),与伊利诺伊大学芝加哥分校(UIC)的手术模拟团队合作,由PI教授Pat Banerjee领导,ImmersiveTouch-Sensimmer总裁。虚拟培训师支持通过超声乳化(“phaco”)进行白内障手术的教学。第一阶段生产了一个原型撕囊训练器,目前正在NEI-ARRA补充下完善。第二阶段建议创建一个超声乳化培训师,并对两个培训师进行验证。任务1. ARRA Phase I撕囊模拟器。第一阶段没有为验证提供资金。验证旨在显示撕囊术的外观、结构和并发有效性。撕囊模拟器的评分系统包括撕囊过程中透镜囊膜的单独镊子抓取次数、镊子击打透镜的次数以及撕囊的总时间。最近增加了定性因素,如囊袋撕裂的最佳尺寸和形状,以及避免错误,如径向撕裂、角膜切口应力和角膜接触。仍需要设计和验证一种用于对现场手术性能进行评分并将其与模拟器性能相关联的系统。任务2.开发II期撕囊模拟器。第I阶段模拟器旨在仅模拟单个标准撕囊病例以进行验证。商业化将需要针对个体患者变化的II期撕囊模拟器。患者的变化可能会影响前囊和破裂边缘的可见性或可及性(角膜混浊、玻璃体混浊、深眼、前房深度、皮质性白内障)以及眼和透镜囊的机械稳定性或材料性质(不自主眼球运动,虹膜后粘连=虹膜附着于透镜,晶状体悬韧带薄弱,玻璃体压力高,年轻人与老年人的囊膜厚度和脆性,前囊上的钙化斑块)。任务3.开发超声乳化模拟器。受训者使用双手双脚:右手=超声乳化手柄;左手=髓核操纵器;右脚=超声乳化踏板;左脚=显微镜调节。真实的脚踏板(例如,Alcon),超声乳化脚踏板将控制虚拟超声乳化头端的三种模式:(1)灌注;(2)灌注+抽吸;(3)灌注+抽吸+超声功率。SENSIMMER将在虚拟现实中模拟超声乳化头端,并通过SensAble Phantom Omni触觉机器人的手柄对器械手柄进行建模。培训师将能够模拟标准手术技术(例如,超乳劈切;分而治之)和不寻常的临床病例(例如,弱小带)。受训者将学习控制流体流速和超声功率。任务4.打开超声乳化模拟器。验证将再次旨在证明表面,结构和并发有效性,如上所述。这将需要开发模拟和实时超声乳化的评分系统。模拟超声乳化术的评分系统将包括手术总时间、通过头端总路径长度测量的器械头端操作效率以及适当使用超声乳化功率设置以避免角膜热损伤等因素。
公共卫生相关性:ImmersiveTouch-Sensimmer,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第一和第二阶段之后,SENSIMMER虚拟超乳培训器将包括针对白内障手术中两个最困难的部分任务的开发良好的模块:撕囊和超声乳化。
