    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 proximal housing and a distal retractor. At least one stability thread can extend around a perimeter of at least a portion of the distal retractor. In some embodiments, the stability thread can be mechanically adjustable to change a diameter of the distal retractor.

    摘要： Devices and methods are disclosed for accessing a body cavity or other surgical site while providing optimal device length and improved tissue retraction, device retention and stability, and seal integrity. A surgical access device is disclosed that generally comprises an external seal housing having at least one working channel and that is coupled to a flexible and/or resilient retractor. The retractor can include a resilient ring at its distal circumference configured to be deformed to facilitate insertion through an incision and then to return to an undeformed state having a diameter greater than a diameter of the incision once within a body cavity. Various means of coupling the retractor to the housing are disclosed, as are various types of seals that can be included within the housing. “Low-profile”and “peel-away cannula” embodiments of the surgical access device are disclosed, along with methods of accessing a body cavity using such devices.

    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 an elongate hollow tube having a proximal end that is configured to be positioned adjacent to a tissue surface and a distal end configured to extend through a body wall into a body cavity. The proximal end of the device can be can be configured to allow the proximal-most portion of the surgical access device to rest flush or substantially flush against a tissue surface of a patient when the device is inserted into the patient. In some embodiments, the elongate hollow tube can have a non-circular cross-section.
