Abstract
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.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
161 words
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, and wherein each prong has an arced cross-section and is thinner than it is wide.
Claim 2
Dependent Claim
161 words
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, and wherein each prong has an arced cross-section and is thinner than it is wide.
Claim 3
Dependent Claim
41 words
A laparoscopic specimen extraction port according to claim 1 , wherein the forward portion is radially-enlarged relative to an inside surface of the holding ring such that the forward portion prevents the holding ring from sliding forwardly beyond the forward portion.
Claim 4
Dependent Claim
41 words
A laparoscopic specimen extraction port according to claim 1 , further comprising a releasable holding mechanism to selectively secure the holding ring at the rear end of the intermediate portion when the laparoscopic specimen extraction port is in the contracted position.
Claim 5
Dependent Claim
38 words
A laparoscopic specimen extraction port according to claim 3 , wherein rotation of the port relative to the holding ring disengages the holding mechanism to allow the laparoscopic specimen extraction port to be manipulated into the expanded position.
Claim 6
Dependent Claim
139 words
A laparoscopic specimen extraction port according to claim 4 , wherein the holding mechanism comprises: a forwardly-facing surface defined by the holding ring; a notch on an inside surface of the holding ring, the notch extending rearwardly from the forwardly-facing surface; and a protrusion extending from the outer surface of the intermediate portion, a rearward edge of the protrusion being in front of the forwardly-facing surface when the laparoscopic specimen extraction port is in the contracted position to prevent the port from moving rearwardly relative to the holding ring, wherein rotation of the port relative to the holding ring aligns the protrusion with the notch, thereby allowing the protrusion to move through the notch and the port to move rearwardly relative to the holding ring to permit the laparoscopic specimen extraction port to be manipulated into the expanded position.
Claim 7
Dependent Claim
22 words
A laparoscopic specimen extraction port according to claim 2 , wherein the forward portion of the port comprises a radially-outwardly-tapering outer surface.
Claim 8
Dependent Claim
70 words
A laparoscopic specimen extraction port according to claim 6 , wherein each prong includes a forward tip that has inside and outside surfaces, and wherein the inside surface of the forward tip tapers radially-outwardly so that, when the laparoscopic specimen extraction port is in the contracted position, the outwardly-tapering inside surface of the forward tip of each prong adjoins the outwardly-tapering outer surface of the forward portion of the port.
Claim 9
Dependent Claim
27 words
A laparoscopic specimen extraction port according to claim 7 , wherein the forward portion of the port includes a tip that tapers radially-inwardly from the forward portion.
Claim 10
Dependent Claim
28 words
A laparoscopic specimen extraction port according to claim 2 , wherein the prongs comprise a flexible material that expands radially-outwardly during expansion of the laparoscopic specimen extraction port.
Claim 11
