MULTI-PLANAR OBTURATOR WITH FOLDABLE RETRACTOR |
摘要 |
Various methods and devices are provided for providing surgical access to a body cavity using a surgical access device that can include an elongate flexible member having proximal and distal ends and a sidewall extending therebetween. The elongate flexible member can be movable between a first position in which the elongate flexible member has at least one longitudinal fold formed in the sidewall such that a width of a longitudinal opening extending through the elongate flexible member is reduced, and a second position in which the fold in the sidewall is unfolded such that a width of the longitudinal opening is increased. In some embodiments, an obturator having expansion members can be used to unfold the elongate flexible member.
