An access port provides access through tissue to a surgical site or field, such as at the spine, in a minimally invasive manner. In one configuration, the access port is defined by a cannula-style retractor having a passage therethrough, a first end for insertion through tissue to the surgical site and a second end for positioning external therefrom. An access controller is associated with the second end of the retractor, the access controller selectively lockable to the retractor and including a passage leading to the retractor passage. The access controller may be used to selectively move the retractor and thus change the access path defined by the access port to the surgical site. The access controller may include features such as mirrors, light sources and retractor holders. The access port permits a user to clearly view and access the surgical field, including areas medial thereto, in a minimally invasive manner.

A method for creating and accessing a graphical user interface in the overscan area outside the area of the display normally visible to users of the common operating systems. This normal display area is generally known as the “desktop”. The desktop serves as the graphical user interface to the operating system. The desktop displays images representing documents and applications available to the user (icons). The desktop is restricted in the common environments to a predetermined set of resolutions (e.g., 640×480, 800×600, 1024×768) as defined by VGA and SuperVGA standards. Displayable borders outside this area are the overscan.
