Containment bag

A containment bag assembly for extracting a tissue specimen from a patient, the containment bag assembly comprising:

• a containment bag comprising one or more segmenting wires;
• an outer tube comprising a distal end and a proximal end, the outer tube further comprising a trocar;
• a flexible ring, the flexible ring configured to form a top opening of the containment bag, wherein the flexible ring comprises:
• two ring subassemblies, each ring subassembly comprising a proximal end and a distal end;
• and
• a flexible member positioned between and coupled to the distal ends of the two ring subassemblies, wherein the flexible member is movable between a collapsed position and an expanded position, the flexible member further having a lead-in feature, the lead-in feature having a blunt tip, wherein the blunt tip is configured to protrude past the distal end of the outer tube when a distal tip pressure is at or above a threshold and retract back into the lead-in feature of the flexible member when the distal tip pressure is below the threshold;
• wherein, when the flexible member is in the collapsed position, the two ring subassemblies are in a collapsed position and the containment bag is configured to be contained within the outer tube, and
• when the flexible member is in the expanded position, the two ring subassemblies and the flexible member bias the top opening of the containment bag to an open position to enable placement of the tissue specimen within the containment bag.
