Articulation stop
Abstract:
A joint apparatus includes an outer joint portion having an opening end, an outer joint axis, and an outer joint inside surface defining, at least in part, an internal vault. The joint apparatus also includes an inner joint portion including a spider interposed within the outer joint portion and a shaft extending through the opening end. The spider includes a trunnion. The trunnion is at least partially interposed within the vault. The shaft defines a shaft axis. The inner joint portion includes an angular range of motion limiting device that selectively restricts the articulation of the shaft relative to the outer joint to prevent the shaft from contacting the outer joint.
