Methods and Devices for Providing Access Into a Body Cavity

摘要

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 movable sealing ports for receiving surgical instruments. Each movable 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 movable sealing port can be rotatable relative to the housing and each sealing element can be rotatable relative to the housing along a predetermined orbital path.

主权项

1. A surgical device, comprising:
a distal retractor configured to be positioned in an opening formed in tissue to provide a pathway through the tissue; a proximal lock ring configured to releasably mate to the retractor; and a base configured to be captured between the retractor and the lock ring when the lock ring is releasably mated to the retractor, the base being configured to rotate 360° about a central point of the base relative to the lock ring and the retractor when the lock ring is releasably mated to the retractor, the base including a first sealing port configured to form a seal around a first surgical instrument advanced therethrough, the base including a second sealing port configured to form a seal around a second surgical instrument advanced therethrough, the first sealing port being configured to rotate 360° about a central point of the first sealing port relative to the lock ring, the retractor, and the second sealing port, the central point of the first sealing port being laterally offset from the central point of the base, the second sealing port being configured to rotate 360° about a central point of the second sealing port relative to the lock ring, the retractor, and the first sealing port, and the central point of the second sealing port being laterally offset from the central point of the base and being laterally offset from the central point of the first sealing port.
