A cannula device for use in laparoscopic surgery includes a rigid tubular member and an expandable receiver connected to a distal end of the tubular member. The receiver portion of the cannula expands from a substantially cylindrical configuration to an expanded pocket for receiving a severed organ or organ part, thereby facilitating removal of the severed organ from a patient's abdomen during a laparoscopic surgical procedure.
