Abstract

In one aspect, an apparatus for supporting an adjustable surgical platform is disclosed. In one embodiment, the apparatus includes a supporting platform portion with a body portion that defines bore along a central axis. Arm portions with engaging means extend radially from the supporting platform portion. The apparatus also includes a shaft portion extending from the supporting platform portion in a first direction, with a shaft body portion that defines a bore along a longitudinal axis B. The bore of the shaft body portion is in communication with the bore of the supporting platform portion. The apparatus further includes a base portion connected to the shaft portion, and that defines a bore in communication with the bore of the shaft portion and the bore of the supporting platform portion. Mounting means are configured to secure the base portion to a region of interest of a living subject.
