Abstract
Methods and devices are provided for providing surgical access into a body cavity. In one embodiment, a surgical access device is provided that includes a housing coupled to a retractor. The housing can be have one or more sealing ports for receiving surgical instruments. Each sealing port can include one or more sealing elements therein for sealing the port and/or forming a seal around a surgical instrument disposed therethrough. Each sealing port can be in a fixed position relative to the housing and can be rotatable with the housing relative to the retractor. A plurality of safety shields can extend from the housing into the retractor to protect the retractor from instruments inserted through the sealing ports and into the retractor.
