ABSTRACT:
A laparoscopic surgical extraction port (LSEP) includes a port having a radially-enlarged distal end. A sheath having a plurality of circumferentially-spaced prongs is slidingly mounted onto the port. With the prongs contracted radially-inwardly and the LSEP in its contracted position, a surgeon inserts the LSEP into a patient's abdominal cavity through an incision. The surgeon then expands the LSEP by pulling the port rearwardly such that the radially-enlarged distal end expands the prongs radially-outwardly. The surgeon then positions a specimen and endo-bag in the funnel formed by the expanded prongs. The specimen, endo-bag, and prongs are thereafter simultaneously extracted through the incision. A radially-inward force that is applied to the prongs by the incision substantially prevents the specimen from bunching or rupturing during the extraction process.
