SBIR Phase I: New laparoscopic power morcellator with containment system for minimally invasive surgeries.

这个SBIR第一阶段项目的更广泛的影响/商业潜力是推动腹部微创手术(MIS)新系统的开发。拟议的手术将是一种更安全、更清洁、更有效的方法，可以通过小切口取出子宫肌瘤、子宫、肾脏或脾等组织标本。现有的管理信息系统的方法和设备还不能在不扩大切口或限制外科医生的可视化和可操作性的情况下，将分离的组织从腔内移除。建议的方法将使用新的、更安全和更有效的工具，通过管理信息系统来取出大的组织标本。拟议的项目将探索一种集成的动力粉碎机和遏制系统的平移，以切割和移除腔内的大组织标本，而不会随后受到污染。拟议的项目是用标准的管理信息系统设备进行测试，包括一个5 mm的30度角度的腹腔镜，腹腔镜摄像机，光源和监视器，以及一个二氧化碳快速注气器。被切割的标本将是牛舌和土豆，这是肌瘤子宫的代表。拟议的项目将提供手术方案，以1)提高安全性和效率，以及2)防止被切除的组织对空洞的污染。模拟器和套管针套筒将使用高精度的ATP测试来评估组织污染的痕迹。该项目将探索与该程序相关的参数空间，包括动力粉碎机处于工作状态的最长时间、叶片位置、叶片温度和空腔压力；以及叶片和轴的裂纹和疲劳断裂的手术后检查；以及容器的磨损、穿孔和泄漏。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

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.
