Many surgeons are faced with inoperable or only partially operable brain lesions, such as tumors. Even when surgery is feasible, patient outcome is greatly affected by blood loss or infection. This has led many physicians toward non- or minimally-invasive surgery, which demands specialized toolkits. Focused ultrasound has great potential for assisting in such procedures due to its ability to focus a few cm away from the surface of the transducer. In a prior study, we developed a focused ultrasound prototype that could fit within a BrainPath trocar, specifically made for minimally invasive brain surgery. Here, we present the design and fabrication of a second prototype that reduces size, is MR-compatible, and has electronic steering capabilities.
许多外科医生都面临着无法手术或只能部分手术的脑部病变，如肿瘤。即使手术可行，患者的预后也会受到失血或感染的极大影响。这使得许多医生倾向于非侵入性或微创性手术，而这需要专门的工具包。聚焦超声因其能够在距换能器表面几厘米处聚焦，在辅助此类手术方面具有巨大潜力。在先前的一项研究中，我们开发了一种聚焦超声原型，它可以安装在专门用于微创脑部手术的BrainPath套管针内。在此，我们展示了第二个原型的设计与制造，该原型减小了尺寸，与磁共振兼容，并具有电子转向功能。
