Abstract

A surgical instrument can be used to capture and retrieve tissue, or other specimens, from within the body of a patient through a single trocar port. The surgical instrument can include a grasper, wherein the grasper can be configured to capture a specimen, and a specimen retrieval bag, wherein the specimen retrieval bag can be configured to at least partially surround, or encapsulate, the captured specimen when the specimen retrieval bag is in a deployed position. In certain embodiments, the retrieval bag can be inverted as it is moved between undeployed and deployed positions. In various embodiments, the surgical instrument can further include a snare operably engaged with the specimen retrieval bag, wherein the snare can be configured to at least partially close the bag. A vacuum can be placed in communication with the bag to reduce the size of the bag before it is removed from the surgical site.

2. The surgical instrument of claim 1, wherein said actuator comprises a snare loop configured to at least partially close said specimen retrieval bag.

3. The surgical instrument of claim 1, wherein said specimen retrieval bag defines a perimeter, and wherein said actuator comprises a snare engaged with at least a portion of said perimeter.

4. The surgical instrument of claim 1, further comprising an outer sheath, wherein said outer sheath is configured to at least partially surround said specimen retrieval bag when said specimen retrieval bag is in said undeployed position.

5. The surgical instrument of claim 4, wherein said outer sheath is slidable between a distal position in which said outer sheath at least partially surrounds said specimen retrieval bag and a proximal position in which said specimen retrieval bag can be moved between said undeployed position and said deployed position.

6. The surgical instrument of claim 1, further comprising a trocar including a trocar lumen, wherein said grasper and said specimen retrieval bag are slidably received within said trocar lumen.

7. The surgical instrument of claim 1, wherein said grasper further includes a grasper lumen, and wherein said grasper lumen is configured to place said specimen retrieval bag in fluid communication with a vacuum source.

8. The surgical instrument of claim 1, wherein said grasper is at least partially positioned within said specimen retrieval bag when said specimen retrieval bag is in said undeployed position.

9. The surgical instrument of claim 1, wherein said grasper is at least partially positioned within said specimen retrieval bag when said specimen retrieval bag is in said deployed position.

10. The surgical instrument of claim 1, wherein said shaft comprises:

a shaft outer surface; and

a distal guide extending from said shaft outer surface, wherein said actuator extends through said distal guide.

11. 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 and at least one movable jaw, wherein said at least one movable jaw is configured to capture a specimen; and

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, wherein said specimen retrieval bag comprises a covering surface and an outer surface, 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 attachment member, wherein said specimen retrieval bag includes a first end and a second end, wherein said first end is affixed to said grasper by said attachment member at a bag attachment location, wherein said second end is positioned proximal with respect to said first end when said specimen retrieval bag is in said undeployed position, and wherein said second end is positioned distal with respect to said first end 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 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 at least one movable jaw 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 at least one movable jaw than said bag attachment location when said specimen retrieval bag is in said deployed position.
