摘要：
Described herein are devices and systems that can be used to perform minimally-invasive procedures including dilation, distraction and delivery of an implant. In one aspect, disclosed herein is a surgical access and orthopedic distraction device having a first cannula element including a first elongate portion and a first head portion and a second cannula element including a second elongate portion and a second head portion. The first and second head portions reversibly mate to define a lip surrounding at least a portion of a proximal access portal of an elongate, tubular working channel formed by the first and second elongate portions.
