Tissue specimen retrieval device with assisted deployment

A tissue specimen retrieval device, comprising:

• a first shaft including a pair of elongated slots defined in a distal end thereof and a pair of corresponding windows defined proximally of the pair of respective slots;
• a second shaft including a bag brim attached thereto, the second shaft telescopically movable within the first shaft between a retracted position, wherein the bag brim is disposed within the first shaft and a first deployed position wherein the bag brim at least partially deploys distally from the first shaft forming a substantially circular enclosure for supporting an open end of a tissue specimen bag thereon;
• and
• a pair of hook members each having an arm, a first end operably engaged to the bag brim and a free end including a hook at a distal end thereof, wherein, upon deployment from the first deployed position to a second deployed position, the hook of each hook member engages a respective window defined in the first shaft allowing each respective arm of each hook member to pivot outwardly within respective slots defined within the first shaft member to more fully deploy the bag brim and maximize the open end of the tissue specimen bag.
