Nami Surgical is a spin-out from the University of Glasgow. Biomedical engineers from the Centre for Medical and Industrial Ultrasonics (C-MIU) in the EPSRC Ultrasurge (Surgery enabled by Ultrasonics) Programme team ([www.gla.ac.uk/research/ultrasurge/][0]) have invented a solution to a complex problem in ultrasonic surgical devices.Ultrasonic scalpels are handheld surgical devices that simultaneously cut and cauterise. These devices are the gold standard energy instrument used in \>80% of minimally invasive surgeries. Feedback from surgeons is that they strongly prefer ultrasonic scalpels over conventional cutting tools.In parallel, surgical robotic devices are rapidly diffusing throughout the global healthcare system, with dozens of firms formed since 1999 to develop and manufacture these products. It is forecast that by 2025, close to 100% of US hospitals will have at least one surgical robot, up from about 25% in 2016\.However, due to the technical characteristics and physical limitations of existing ultrasonic scalpels they cannot be used with surgical robots. Existing scalpels have transducers that are too large for laparoscopic ports and thus require long end effector waveguides to transfer energy to the surgical site. These waveguides cannot be bent, lack manoeuvrability at the distal end, and generate heat (\>190C) that damages tissue and smoke that reduces visibility and is a biohazard.Our solution is a miniaturised ultrasonic scalpel that is compatible with robotic surgery. This patent-pending technology allows the ultrasonic scalpel to be mounted directly as the end effector of a wristed robotic arm so addressing a real clinical and market need.[0]: https://www.gla.ac.uk/research/az/ultrasurge/

NAMI Surgical是从格拉斯哥大学衍生出来的。来自医学和工业超声中心(C-MIU)的生物医学工程师在EPSRC超声(超声波实现的手术)计划小组([www.tar.ac.uk/Research/asussuge/][0])中发明了一种解决超声波手术设备中复杂问题的解决方案。超声刀是一种同时切割和烧灼的手持手术设备。这些设备是80%的微创手术中使用的黄金标准能量设备。外科医生的反馈是，他们强烈喜欢超声波手术刀，而不是传统的切割工具。与此同时，外科机器人设备正迅速普及到全球医疗体系，自1999年以来成立了数十家公司来开发和制造这些产品。据预测，到2025年，近100%的美国医院将拥有至少一个手术机器人，而2016年这一比例约为25%。但由于现有超声刀的技术特点和物理限制，它们不能与手术机器人一起使用。现有的手术刀的传感器对于腹腔镜端口来说太大了，因此需要长端效应器波导来将能量转移到手术部位。这些波导不能弯曲，在远端缺乏机动性，产生的热量(190C)会破坏组织，产生烟雾，降低能见度，是一种生物危险。我们的解决方案是一种与机器人手术兼容的微型超声刀。这项正在申请专利的技术允许超声波手术刀直接安装在扭曲的机械臂的末端执行器上，从而满足了真正的临床和市场需求。[0]：https://www.gla.ac.uk/research/az/ultrasurge/
