    • A surgical access system including a tissue distraction assembly and a tissue retraction assembly, both of which may be equipped with one or more electrodes for use in detecting the existence of (and optionally the distance and/or direction to) neural structures before, during, and after the establishment of an operative corridor to a surgical target site. The tissue retraction assembly has a plurality of blades which may be introduced while in a closed configuration, after which point they may be opened to create an operation corridor to the surgical target site, including pivoting at least one blade to expand the operative corridor adjacent to the operative site. The surgical access system further includes pressure sensing technology to measure the pressure being exerted upon body tissues before, during, and/or after retraction and/or distraction.
    • 一种包括组织牵引组件和组织缩回组件的手术进入系统,其两者可以装备有一个或多个电极,用于检测神经结构的存在(以及可选的距离和/或方向) 以及在手术目标地点建立手术走廊之后。 组织缩回组件具有多个叶片,其可以处于闭合构型中而被引入,之后它们可以被打开以形成到外科手术目标部位的手术走廊,包括枢转至少一个叶片以使相邻的手术走廊扩张 手术部位。 手术进入系统还包括压力感测技术,以测量在收缩和/或分注之前,期间和/或之后施加在身体组织上的压力。
