摘要：
Methods and devices are provided for providing access through tissue to a surgical site. A surgical access device can be configured to be positioned in tissue to provide access through a working channel of the access device to a body cavity underlying the tissue. The access device can include a sealing element positioned at least partially within the working channel. The sealing element can be formed of a puncturable self-sealing material such as a gel and/or a foam configured to provide a channel seal that seals the working channel when no instrument is inserted through the sealing element and configured to provide an instrument seal that provides a seal around one or more surgical instruments inserted through the sealing element.
