DEVICES, SYSTEMS, AND METHODS FOR PROVIDING SURGICAL ACCESS AND FACILITATING CLOSURE OF SURGICAL ACCESS OPENINGS
摘要：
A method of surgery includes positioning a cannula within an opening in tissue and inserting a guide member into the cannula. The cannula includes an elongated portion having a base and an elongated tubular member extending distally from the base. The elongated tubular member includes an annular wall defining a longitudinal passageway. At least one slot extends through the annular wall and is disposed in communication with the longitudinal passageway. The guide member includes a guide housing and an elongated guide shaft. The guide member defines at least one lumen extending therethrough. The method further includes releasably engaging the guide housing with the base. Upon engagement of the guide housing with the base, the at least one lumen is aligned with the at least one slot to define a guide passageway through the guide member and cannula.
摘要（中）：

一种手术方法包括将套管定位在组织中的开口内并将引导构件插入套管中。 套管包括具有基部的细长部分和从基部向远侧延伸的细长管状部件。 细长管状构件包括限定纵向通道的环形壁。 至少一个槽延伸穿过环形壁并与纵向通道连通地设置。 引导构件包括导向壳体和细长导向轴。 引导构件限定延伸穿过其中的至少一个内腔。 该方法还包括可释放地将引导壳体与基座接合。 在引导壳体与基座接合时，至少一个内腔与至少一个狭槽对齐以限定穿过引导构件和插管的引导通道。
