Abstract
An access system is provided for establishing an access path to a surgical site within a patient. The access system comprises an access portal defining a working channel with a central axis, and an adaptor with a mating section mountable to the access portal. The adaptor is selectively rotatable about the central axis. The access portal includes a plurality of openings and the adaptor includes a plurality of projections, each of the projections and openings being arranged so that, in a first orientation, the openings and projections align to allow mounting of the adaptor to the access portal and, in a second orientation, the openings and projections do not align to prevent disassociation between the adaptor and the access portal. The adaptor also includes a holder for a viewing device, the viewing device being movable with the adaptor about the access portal and vertically translatable relative to the access portal.

14. A method of viewing a spinal site during a surgical procedure using an access system comprising the steps of:
-
dilating a patient'"'"'s skin and tissue with one or more dilators to create an access path to a spinal site; placing an access portal of the access system over the one or more dilators, the access portal defining a working channel with a central axis and having at least one opening; securing a viewing device to the access portal; and rotating the viewing device about a central axis of the access portal to position the viewing device to view the spinal site, wherein the step of placing the access portal includes the step of mating an adaptor having at least one projection corresponding to at least one opening in the access portal, wherein the step of mating the adaptor to the access portal including the step of placing the at least one projection of the adaptor in the at least one opening of a first flange of the access portal, wherein the access portal include the first and a second flange spaced apart from one another to define a channel wherein the step of securing a viewing device to the access portal includes a step placing a mounting portion of the viewing device in a first aperture of a holder of the adaptor, wherein the holder extends proximally above a proximal end of the access portal and includes a first aperture with an axis that is aligned with the working channel of the access portal, the first aperture being configured to receive the mounting portion of the viewing device.
