A tissue retrieval device comprises a tissue retrieval bag and resilient arms. The bag is releasably engaged with the resilient arms. One or two resilient arms expand the bag along a first plane to open the mouth of the bag. Another resilient arm expands the bag along a second plane to unfurl the bag. The first plane is substantially perpendicular to the second plane. The device further comprises a support tube having a passageway and a push/pull rod slidingly positioned within the passageway. The resilient arms are engaged with the push/pull rod such that the resilient arms and the push/pull rod travel uniformly relative to the longitudinal axis of the support tube. The arms collapse within the support tube and are resiliently biased to extend outwardly when the push/pull rod is translated distally relative to the support tube to expose the bag and arms.
