A collapsible and expandable receptacle that can be inserted into a patient's cavity through a laparoscopic port (sleeve) is disclosed herein. The receptacle is configured so that when it enters the cavity it can be expanded or opened into a shape of a bowl or cone. A targeted tissue specimen can then be placed inside the expanded receptacle, and the surgeon has the room and visibility to cut the tissue with a power morcellator and avoid severing the bag or spreading unwanted particulate tissue to other areas inside the patient. Once the specimen has been cut and removed, the empty receptacle can be collapsed and removed out the same tissue removing sleeve.
