/></p><p><span>医用超声是一种安全有效的重要医学诊断方式，但通常用于医院的超声扫描仪器都体积较大，不具备便携性，但手持式超声的出现改变了这种状况，手持超声将传统笨重的大型超声台式机变成可随身携带、手机大小的彩超设备，从根本上改进了医生对疾病的诊断流程更为灾难、战争等特殊场景的医疗诊断带来革命性变化。</span></p><p><br /></p><p><p><img

Research报告讯，掌超将在2020-2025年迎来增长高峰，到2023年，全球掌上超声市场规模预计将超过4亿美元！全球范围内研发，生产手持式超声的厂家虽然不算多国外品牌有<strong>Butterfly Network</strong>、GE医疗、飞利浦医疗等，国内主要品牌有飞依诺、索诺星等。</span></p><p><br /></p><p><p><img

Medical公司旗下产品，该公司成立于2010年，由弗吉尼亚大学的研究人员成立。联合创始人威尔·莫尔丁（Will Mauldin）在达顿商学院（Darden School of Business）攻读生物医学工程（BME）博士生课程后，创立了里凡纳。威尔希望能够利用他在医学超声技术方面的专业知识来解决硬膜外麻醉和脊髓麻醉的高失败率。幸运的是，威尔的一位BME研究生同学有着丰富的的工业产品开发经验，因此凯文·欧文被招募来充实团队并正式成立公司。</span></p><p><br /></p><p><video width="100%" height="580" controls="controls"><source src="http://mpvideo.qpic.cn/0bf27qabaaaanqalfguwnjpfb7gdcd6aaeaa.f10002.mp4?dis_k=817d930e356078211e8d1ac45ee0ddd4&dis_t=1602649813" type="video/mp4"></source></video></p><p><br /></p><p><span>用传统方式进行硬膜外和脊柱麻醉的麻醉师需要经过大量训练，此外还需要有足够经验才能感觉到针头何时到达既定位置。这个过程还需要有患者的耐心配合，很难做到万无一失。特别是对于肥胖患者、脊柱狭窄或侧凸等异常患者来说更是如此。<br /></span></p><p><span><br /></span></p><p><span>因此，当麻醉师推送针头的时候，通常需要另一名超声医生在侧操作超声设备。据大量数据表明，超声引导脊柱麻醉的成功率和患者安全性均高于人工触诊。但同时，临床证据和实践情况往往还存在差异，原因是与常规超声相关的学习曲线非常陡峭，操作人员培训难度较大。根据研究表明，神经超声引导的效果几乎总是依赖于专业超声医生的水平。同时，大量研究还表明，即使经过一对一的培训和数百次手术之后，普通麻醉医生仍然无法达到利用超声引导脊柱麻醉的水平。</span></p><p><span><br /></span></p><p><p><img src="image/20201014/00a205bb9ae798a3591e61c5ecadbb52_4.jpg" /></p></p><p><br /></p><p><span>Accuro手持式炒成则能够在硬膜外和脊柱麻醉的过程中帮助减轻超声医生的压力。Accuro操作简单，并且在硬膜外和脊髓麻醉时提供良好辅助。当医生执行与神经轴麻醉相关的手术时，更轻松的获得所需椎间隙的定位。也就是说，能够提高麻醉效率。该设备的出现，能大大减轻培训负担，使所有麻醉医生都能从神经超声轻松获益。</span></p><p><span><br /></span></p><p><span>Accuro为手持式设备，体积与普通智能手机大小相仿，由电池供电，重量不到500克。该设备通过两项关键的新超声成像技术解决了上述问题。第一个是BoneEnhance的重建骨骼结构图像的新方法，突出显示骨骼表面。第二个是SpineNav3D的脊柱导航技术，该技术可对关键的脊柱标志（例如棘突和硬膜外腔）提供实时的自动化检测和深度测量。公司有信心这两个技术将能使麻醉师快速上手。</span></p><p><br
