The broader impact/commercial potential of this SBIR Phase I project is to advance the development of a novel system for abdominal minimally invasive surgery (MIS). The proposed procedure will be a safer, cleaner, and more efficient method of removing tissue specimens, such as a uterine fibroid, uterus, kidney or spleen, through a small incision. Existing MIS methods and instruments are not yet optimized for the removal of the separated tissue from the cavity without enlarging an incision or limiting the surgeon's visualization and maneuverability. The proposed method will use novel, safer and more efficient instruments developed for the removal of large tissue specimens via MIS. The proposed project will explore translation of an integrated power morcellator and containment system for cutting and removing large tissue specimens from inside a cavity without subsequent contamination. The proposed project is to conduct tests with standard MIS equipment, including a 5mm 30 degree angled laparoscope, laparoscopic camera, light source and monitor, and a CO2 rapid insufflator. The specimens to be cut will be beef tongue and potato, which is representative of a fibroid uterus. The proposed project will inform a surgical protocol to 1) improve safety and efficiency, and 2) prevent cavity contamination by the removed tissue. The simulator and trocar sleeves will be evaluated for traces of tissue contamination using the highly-precise ATP test. The project will explore the parameter space associated with the procedure, including the maximum time the power morcellator is in the on position, blade temperatures, and cavity pressure; as well as post-procedure examinations of the blades and shaft for cracks and fatigue fractures; and of the containers for abrasions, punctures and leaks.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该SBIR I期项目的更广泛影响/商业潜力是推进腹部微创手术（MIS）新型系统的开发。拟议的程序将是一个更安全，更干净，更有效的方法，通过一个小切口切除组织标本，如子宫肌瘤，子宫，肾脏或脾脏。现有的MIS方法和器械尚未优化用于在不扩大切口或限制外科医生的可视性和可操作性的情况下从腔中移除分离的组织。所提出的方法将使用新型、更安全、更有效的器械，用于通过MIS切除大型组织标本。 拟议的项目将探索一个集成的电动粉碎器和遏制系统的翻译，用于切割和从腔内取出大组织标本，而不会造成后续污染。拟定项目是使用标准MIS设备进行测试，包括5 mm 30度角腹腔镜、腹腔镜摄像机、光源和监视器以及CO2快速吹入器。待切割的标本将是牛舌和土豆，这是子宫肌瘤的代表。拟议项目将为手术方案提供信息，以1）提高安全性和效率，2）防止切除组织污染腔体。 将使用高精度ATP试验评价模拟器和穿刺器套管的组织污染痕迹。该项目将探索与手术相关的参数空间，包括电动粉碎器处于打开位置的最长时间、刀片温度和腔体压力;以及刀片和轴的术后检查，以检查是否存在裂纹和疲劳断裂;以及用于擦伤的容器，该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查进行评估，被认为值得支持的搜索.
