摘要:
A surgical penetrating system includes a cannula and an obturator. The cannula has an outer wall arranged about a longitudinal axis and a longitudinal opening. At least one substantially linear penetrating member is mounted with respect to the outer wall of the cannula and extends in a general longitudinal direction with respect to the longitudinal axis. The penetrating member is adapted to facilitate passage of the cannula through tissue. Another embodiment of the surgical penetrating system includes a cannula having a longitudinal bore and a penetrating member at least partially and slidably mounted within the longitudinal bore of the cannula. The penetrating member has at least one leg and is axially movable between non-deployed and deployed positions. Moreover, the penetrating member can be mounted for movement relative to the leading end of the cannula and within the longitudinal bore of the cannula between a non-deployed position and a deployed position.
