Patent ID: 8172772

Claim:
A surgical instrument for use in removing a specimen from within the body of a patient, the surgical instrument comprising: a grasper comprising: a shaft; a distal end; a first jaw; a second jaw, wherein said grasper is configured to capture a specimen between said first jaw and said second jaw; a specimen retrieval bag movable between an undeployed position and a deployed position, wherein said specimen retrieval bag comprises a first opening and a second opening, wherein said grasper extends through said first opening and said second opening, and wherein said specimen retrieval bag comprises a covering surface and an outer surface, an attachment member, wherein at least a portion of said specimen retrieval bag surrounding said first opening is fixedly mounted to said shaft of said grasper by said attachment member at a bag attachment location, wherein said first jaw and said second jaw are closer to said distal end than said bag attachment location, wherein said second opening is movable relative to said first opening, wherein said second opening is larger than said first opening when said specimen retrieval bag is in said deployed position, and wherein said specimen retrieval bag is configured to at least partially surround the captured specimen when said specimen retrieval bag is in said deployed position; and an actuator operably engaged with said specimen retrieval bag at an actuator attachment location, wherein said actuator extends along said shaft of said grasper, wherein said specimen retrieval bag is inverted when said specimen retrieval bag is moved between said undeployed position and said deployed position, wherein said specimen retrieval bag is turned-inside-out when it is inverted, wherein said outer surface of said specimen retrieval bag is positioned adjacent to said shaft when said specimen retrieval bag is in said undeployed position, wherein said covering surface faces away from said shaft when said specimen retrieval bag is in said undeployed position, wherein said covering surface of said specimen retrieval bag is positioned adjacent to said shaft when said specimen retrieval bag is in said deployed position, wherein said outer surface faces away from said shaft when said specimen retrieval bag is in said deployed position, wherein said bag attachment location is closer to said distal end than said actuator attachment location when said specimen retrieval bag is in said undeployed position, and wherein said actuator attachment location is closer to said distal end than said bag attachment location when said specimen retrieval bag is in said deployed position.
