Surgical access device

摘要

A surgical access device provides surgical access through an incision in the body wall to the inside of a body cavity of a patient. The surgical access device has a subassembly with an opening around a center axis and is adjustable between a closed configuration and an open configuration. The surgical access device has a sleeve attached to the subassembly and positionable in the incision. The sleeve defines a passageway through the body wall between the opening in the valve subassembly and the body cavity. The surgical access device also has at least one access channel extending from the subassembly. The access channel is outside the opening and the passageway and provides an access to the body cavity.
