1. A tissue retrieval system comprising:
a tubular introducer having a proximal end and a distal end and a lumen extending between the proximal end and the distal end;
an actuator longitudinally slidable within the lumen of the introducer, the actuator having a proximal end and a distal end;
an actuator cap positioned at a distal end of the actuator
a pair of support arms extending from the actuator cap;
a guide bead;
a tissue retrieval bag coupled to the guide bead and removably coupled to the support arms, the tissue retrieval bag positionable within the lumen of the introducer in a stowed configuration and deployable by longitudinal movement of the actuator within the lumen of the introducer to an open configuration wherein the tissue retrieval bag is suspended from the support arms;
wherein the actuator cap is releasably mateable with the guide bead to maintain a position of the tissue retrieval bag relative to the support arms; and
wherein the actuator cap comprises a cantilever hook extending distally therefrom.
