Patent ID: 8057485

Claim:
A surgical specimen retrieval device, comprising: a housing having an enlarged proximal end and an elongated tubular portion extending from the enlarged end; a pair of spaced finger openings disposed to extend back from the proximal end of the housing; a spool including a toothed gear rotatably mounted within the enlarged proximal end laterally offset from the elongated tubular portion; an elongated deployment rod slidably received within the elongated tubular portion of the housing, the deployment rod having a proximal end and a distal end and serrated teeth carried on a portion of the deployment rod extending from a point near the proximal end to a point intermediate the proximal end and the distal end of the rod, the serrated teeth being disposed to engage the toothed gear on the spool, the deployment rod being movable from an extended position to an inserted position and then to a fully retracted position; a thumb opening disposed to extend back from the proximal end of the deployment rod; a pre-stressed loop disposed to extend forward from the distal end of the deployment rod; a specimen bag having a closable mouth, the bag being removably attached to the pre-stressed loop by interconnecting loose attachments, wherein the bag is initially disposed within the elongated tubular portion of the housing near its distal end, and wherein movement of the deployment rod from the extended position to the inserted position ejects the bag from the distal end of the tubular portion of the housing; a flexible line having a proximal end releasable secured to the spool and a distal end attached to the mouth of the bag; wherein the serrated teeth of the deployment rod are disposed to matingly engage the toothed gear of the spool when the deployment rod is in the extended and inserted positions, and the serrated teeth disengage from the gear when the deployment rod is in the fully retracted position, and movement of the deployment rod from the extended position toward the inserted position rotates the spool to pay out the flexible line, movement of the deployment rod from the inserted position toward the extended position rotates the spool to take up the flexible line and close the mouth of the bag, and movement of the deployment rod to the fully retracted position allows the spool to freely unwind to release the proximal end of the flexible line from the spool allowing the proximal end of the flexible line to exit the distal end of the tubular portion of the housing.
