摘要：
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.
