1. An expandable access port, comprising:
a housing having an expandable conduit coupled thereto and having a threaded region with an external thread disposed along an exterior surface of the threaded region, the expandable conduit including a plurality of tines;
a planar cap coupled to the housing, the planar cap comprising a rounded base and one or more attachment regions projecting laterally outward from the rounded base, the one or more attachment regions each including two substantially parallel side surfaces that extend radially outward relative to the rounded base and an end surface at an end region of the two substantially parallel side surfaces;
an adjustment mechanism releasably coupled to one of the one or more attachment regions, the adjustment mechanism including an elastic member and a lever member for releasably coupling the adjustment mechanism directly to one of the one or more attachment regions; and
an actuation member threadably engaged with the external thread, the actuation member being designed to shift the expandable conduit between a first configuration and an expanded configuration by rotating the actuation member about the exterior surface of the threaded region.
