SURGICAL ACCESS DEVICE INCLUDING LATERAL MOVING SEAL COOPERATING WITH BELLOWS ATTACHED TO PROXIMAL WALL OF CANNULA HOUSING

摘要

A surgical access device includes a seal assembly having an outer seal housing, an inner seal housing, and a seal cooperating with the inner seal housing, the outer seal housing defining a central longitudinal axis and having a longitudinal passage for receiving at least one surgical object therethrough. The surgical access device also includes a bellows configured to engage at least a portion of the inner seal housing cooperating with the seal, the bellows dimensioned and adapted to establish a biasing relationship with the seal. The seal is adapted for lateral movement relative to the central longitudinal axis of the outer seal housing and the bellows is configured to be attached to a proximal wall of the outer seal housing.
