Surgical portal apparatus with armature assembly

A surgical portal apparatus, which comprises:

• a portal housing;
• an elongated portal member connected to the portal housing and extending therefrom, the portal member defining a central longitudinal axis, the portal housing and the portal member having an axial bore for reception and passage of a surgical object;
• and
• an armature assembly including:
• at least two arms disposed within the portal housing, the at least two arms extending at least radially inwardly and positioned to intersect the axial bore, the at least two arms dimensioned and adapted to move relative to the longitudinal axis from a rest position to an activated position during passage of the surgical object, the at least two arms being operatively connected whereby movement of a first arm causes corresponding pivoting synchronized movement of a second arm;
• and
• an outer mount comprising a resilient material and being disposed within the portal housing, the outer mount having the at least two arms at least partially embedded within the resilient material thereof, the outer mount dimensioned and adapted to impart a biasing force to the at least two arms toward the rest position thereof, the outer mount having inner portions defining a passage to permit passage of the surgical object.
