1. A surgical access assembly comprising:
a surgical access device including an elongated shaft having an outer surface; and
a retention anchor selectively slidable along the outer surface of the elongated shaft, the retention anchor including:
an annular body including an opening defined through the annular body; and
an annular disk secured to the annular body, the annular disk including an aperture aligned with the opening through the annular body,
the elongated shaft extending through the opening in the annular body and the aperture in the annular disk, the annular disk transitionable between a first configuration in which the annular disk has a convex shape relative to the annular body to enable the retention anchor to slide along the elongated shaft and a second configuration in which the annular disk has a concave shape relative to the annular body, the concave shape defined between an inner terminal edge of the annular disk and an outer terminal edge of the annular disk to fix a position of the retention anchor on the elongated shaft.
