Abstract
Laparoscopy organ retrieval apparatus and procedures are presented for minimum invasion surgery inclusive of laparoscopic nephrectomy, cholecystectomy and other organ dissection, morsellation removal from the abdomen through a keyhole incision. The apparatus and procedures permit the safe and total removal of an organ from a body cavity in a morsellated condition through the combination utilization of an entrapment envelope sheath. The entrapment envelope having an apparatus for opening and closing, the apparatus controlled from an exterior position of the body cavity wherein the entrapment envelope after entry of the sheath is extruded from the sheath which has been inserted through a laparoscopic port in place in a keyhole surgical opening. The entrapment envelope is constructed of flexible, relatively low bulk fluid impermeable materials having sufficient strength to contain morsellator entry, organ fragmentation and removal.
