Vented specimen retrieval bag

A surgical specimen retrieval apparatus, comprising:

• a proximal handle;
• a flexible specimen bag attached to a distal end of the proximal handle, having an open proximal end and a closed distal end;
• a distal ring supported by the handle and supporting the flexible specimen bag;
• a tube extending within the proximal handle configured for connection at a proximal end of the tube to a source of negative pressure;
• and
• a plurality of channels positioned in the specimen bag in fluid communication with the tube, configured to withdraw fluid from the bag so that the specimen bag closes around a specimen in the bag from the distal end to the proximal end when negative pressure is applied to the tube.
