Abstract
A tissue specimen retrieval device includes a first shaft and a second shaft telescopically movable relative to the first shaft. The second shaft supports an end effector assembly at a distal end thereof and is movable relative to the first shaft between a retracted position, wherein the end effector assembly is disposed within the first shaft, and a deployed position, wherein the end effector assembly extends from the first shaft in an expanded configuration. The end effector assembly includes a bag brim having a wire support with first and second ends that operably engage the distal end of the second shaft. The bag brim is transitionable from a first collapsed configuration within the first shaft to an expanded configuration upon deployment therefrom. The wire support includes torsion springs disposed between the first and second ends that cooperate to facilitate expansion of the bag brim upon deployment from the first shaft.
