介绍一种新的微立体定向框架，称为Microtable，由安装在植入骨的球形标记上的桌面组成。微型工作台是为个别患者的解剖而定制的，以将手术器械引导到指定的目标。植入基准标记物，并进行CT扫描。微型工作台是为标记的位置和所需的手术轨迹量身定做的，并使用计算机数字控制机建造。验证研究是在体模上进行的，这些体模的几何结构类似于人工耳蜗术。用两种不同类型的基准标记对两种设计进行了测试。两种设计的微型工作台的平均定位误差分别为0.37±0.18和0.60±0.21 mm(n=5)。每个微型工作台的建造需要大约6分钟。新的框架实现了高精度和快速制造。我们目前正在使用Microtable对经皮人工耳蜗术的概念进行临床测试。
To introduce a novel microstereotactic frame, called the Microtable, consisting of a tabletop that mounts on bone-implanted spherical markers. The microtable is customized for individual patient anatomy to guide a surgical instrument to a specified target. Fiducial markers are bone-implanted, and CT scanning is performed. A microtable is custom-designed for the location of the markers and the desired surgical trajectory and is constructed using a computer-numerical-control machine. Validation studies were performed on phantoms with geometry similar to that for cochlear implant surgery. Two designs were tested with two different types of fiducial markers. Mean targeting error of the microtables for the two designs were 0.37±0.18 and 0.60±0.21 mm (n = 5). Construction of each microtable required approximately 6 min. The new frame achieves both high accuracy and rapid fabrication. We are currently using the Microtable for clinical testing of the concept of percutaneous cochlear implant surgery.
