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.

Dependent claims

A laparoscopic specimen extraction port having expanded and contracted positions, the laparoscopic specimen extraction port comprising:

an elongated, hollow port having a rearward portion, an intermediate portion, and a forward portion that is radially-enlarged relative to the intermediate portion;
a holding ring disposed radially-outwardly from the intermediate portion and adapted to slide relative to the intermediate portion, the holding ring being disposed at a rear end of the intermediate portion when the laparoscopic specimen extraction port is in the contracted position;
and
a plurality of circumferentially-spaced prongs having rearward ends connected to the holding ring and forward ends extending to the radially-enlarged, forward portion, the forward ends of the prongs expanding radially-outwardly relative to the rearward ends when the laparoscopic specimen extraction port is in the expanded position,
wherein, during transition from the contracted to the expanded position, the radially-enlarged forward portion expands the prongs radially-outwardly.
