摘要：
A surgical portal assembly includes a portal member adapted for positioning within a tissue tract and defining a longitudinal axis with leading and trailing ends. The portal member includes at least one longitudinal port for passage of an object. The portal member comprises a compressible material adapted to transition between a first expanded condition to facilitate securing of the portal within the tissue tract and in substantial seated relation with tissue surfaces defining the tissue tract, and a second compressed condition to facilitate at least partial insertion of the portal within the tissue tract. The portal assembly also includes an elongated member extending through the at least one longitudinal port and mechanically couplable to the portal member adjacent the leading end thereof. The elongated member is adapted to move through the at least one longitudinal port in a trailing direction to exert a compressive force at least adjacent the leading end to cause the portal member to transition toward the compressed condition.
